%% One quote is sufficient. Please place additional entries on the quotes tab.

In fiction, armor has virtually no protective qualities. Characters who wear no armor to speak of are no more (and often less) at risk of injury or death than somebody who is "protected". A single swing of a sword is enough to kill an opponent wearing full plate armor. All arrows are armor-piercing and will penetrate even thick armor like it was just a sheet of paper. Indeed, it's often the case that people who wear armor find themselves far more competent after they either discard it or have it [[ClothingDamage destroyed for them]] by the nice people out to kill them. In the latter case, it leaves one wondering why they bothered with it in the first place, if they can survive attacks that completely demolish their armor anyway.

This trope probably stems from the fact that armor -- especially [[HelmetsAreHardlyHeroic helmets]] -- in movies, games, and other media often serves not to protect characters but to render them [[FacelessGoons faceless and anonymous]], dehumanizing them so they make excellent RedShirts and {{Mooks}} (not to mention that an entire army can be portrayed by a half dozen or so stuntmen). Related to this, quality armor (such as the plate suit that stamps someone as "medieval warrior" on sight) ought to be quite expensive; mooks might be looked at as issued cheap protection that only looks like elite armor. The UnspokenPlanGuarantee may also be connected; the armor represents a plan to be invulnerable, which, once presented to the audience, has to fail or it'd be boringly predictable. (This helps explain why ''hidden'' {{Bulletproof Vest}}s usually work.)

See also TheLawOfDiminishingDefensiveEffort, ArmorPiercingAttack, and AntiArmor. The logical extreme of this trope is the FullFrontalAssault. For non-armor objects that make for bizarrely non-useless armor, see PocketProtector. The best armor, of course, is PlotArmor. When armor isn't useless, but it limits speed, see ShedArmorGainSpeed.

!!Examples:

[[foldercontrol]]

[[folder:{{Anime}} and {{Manga}}]]
* ''Franchise/SailorMoon'': The Sailor Senshi wore nothing but moderately skimpy clothing made of what appears to be cotton, yet appeared to be perfectly capable of keeping their wearers -- exposed skin and all -- protected from everything from flying debris to flames to the vacuum of space. Further, while they were often smacked around, their clothing only showed it when they were fighting the BigBad or somebody directly under them. In the live-action ''Series/PrettyGuardianSailorMoon'', Senshi wears some armor -- a sports-bra-style BreastPlate made of what looks like fiberglass or plastic.
* In the same vein as ''Sailor Moon'', the characters from the ''Franchise/PrettyCure'' series wear different varieties of clothing, but still withstand the same kinds of forces the Senshi dealt with, including space. Unlike the Senshi, their uniforms would get scuffed in major battles, but never tore or ripped.
* ''Literature/FateZero'': The Black Knight [[spoiler:Sir Lancelot]] supposedly wears armor of the highest quality, but due to his insanely high stats, a Noble Phantasm that allows him to wield anything like he was born to do so (including an F15 jet fighter, a gatling gun and a steel pole) makes it almost meaningless, as he is only hit once throughout the entire series (Excluding when Rider ran him over with his A+ Rank Noble Phantasm chariot, which he survived seemingly without any more damage than a few bruises). His armor is technically extremely powerful and very useful, but he doesn´t even need it because he´s so damned good.
* ''Manga/InuYasha'': While in one of the earliest episodes Inuyasha insists on Kagome wearing his robe (a kind of magical fireproof vest), for most of the series a simple SailorFuku had no trouble keeping her safe from harm. And then there's Inuyasha's [[BringMyRedJacket own luck with that red robe]]...
* In the ''{{Mazinger}}'' saga:
** ''Anime/MazingerZ'' tried to avert this trope. [[HumongousMecha Mazinger's]] cockpit offered little protection, and in the first chapters, Kouji repeatedly got hurt and even knocked out because he fought in civilian clothes (and in the manga [[DangerouslyGenreSavvy the villains were aware of that and tried to exploit it]]. In an early story, [[TheDragon Baron Ashura]] commanded a [[{{Robeast}} Mechanical Beast]] to grab Mazinger, fly high and drop it, knowing -as Kouji did- that the freefall's impact would kill the pilot, even if [[SuperRobot Mazinger]] endured it). In order to avoid that, he began wearing a LatexSpaceSuit to protect his body during the fights. It was more protective than plain clothes, but he still got injured while wearing it.
** Another series of the franchise played this trope in a more straight fashion. ''[[Anime/GreatMazinger Tetsuya Tsurugi]]'', ''[[Anime/UFORoboGrendizer Duke Fleed]]'' and their allies wore sturdy {{Latex Space Suit}}s to protect their bodies from harm during the battles. The often got injured nonetheless, especially Tetsuya, who was [[LeeroyJenkins too rash and reckless]].
** On the other hand, ''Manga/NewMazinger'' averted this trope. Kabuto wore a PowerArmor protected him efficiently during the whole story.
* ''Anime/VisionOfEscaflowne'' Van's armour is destroyed in the first fight and he spends the rest of the series fighting in vest and trousers. Except when he is in the eponymous HumongousMecha, where he tends to sufferer a greater number of injuries rather than fewer.
** The series KnightInShiningArmor, Allen Schezar, isn't actually wearing any, although his clothes seem to have abnormally high levels of starch, [[GiantPoofySleeves especially in the shoulders]].
* ''Manga/DragonBall'' - Everybody who wore armor either got rid of it or [[CharacterDeath died]]. Or as often as not, [[DeathIsCheap both]]. However, this isn't due to the uselessness of armor (which was used quite often by even the protagonists) but due to the fact that they eventually got to the point that their superpowers outstripped their armor's ability to protect. It's also explained in some of the earlier seasons, as most characters wore armor or clothing that was weighted for training purposes, and after removing it they become much faster.
** One notable aversion is after Goku's first battle with Vegeta. When Vegeta recovers from his injuries, the doctor reveals that the only reason he's still alive is because his armor protected him from being crushed by Gohan.
* In ''Manga/OnePiece'', armor is usually either not present or is dismantled fairly quickly (ignoring, or course, characters who are literally MadeOfIron). One notable exception is in the Baratie Arc, where a major part of the battle involves Luffy's attempts to get through [[BigBad Don Krieg's]] armor.
* The ''{{Hellsing}}'' anime. Anyone with body armor is ''really'' dead by the end of the arc they show up in, if not the very episode. Now, the vampire in a miniskirt is fairly easy to HandWave. Walter Dornez, who remains human, take out dozens of ghouls, and has no armor greater than a cloth vest, is a bit harder to figure out. However, Walter ''has'' had decades of experience at this sort of work, and thus may be covered under the same rules that protect the OldMaster. Zigzagged with Alucard, who is totally unprotected, gets torn to shreds for it and [[HealingFactor just keeps on going anyways.]]
* In ''[[SamuraiSeven Samurai 7]]'', most of the titular samurai wear no armor, and the armored one is a cyborg. They are shot at frequently, by everything from soldiers to giant mecha.
* ''Anime/NeonGenesisEvangelion'' played with this trope:
** The armour on the Evangelion units protects the pilot but the list of damages is incredible. Broken skull-piece (Sachiel, #3), broken arm (ditto), pierced (Shamshel, #4; Armisael, #16), cut (Zeruel, #14), not to mention nearly turning its pilot into Kentucky Fried Shinji (Ramiel, #5; also aversion to ConvectionSchmonvection against Sandalphon, #11). Also, it can't do anything against psychic attacks at all. [[MindRape Poor Asuka ...]] [[spoiler: The armor's true purpose is to [[RestrainingBolt weaken and keep the Evas under control]]]].
** The multiple layers of armor covering the Geofront become increasingly less effective as the series progress. Ramiel (#5) takes 24 hours to drill through, while Zeruel (#14) penetrates it with just a few energy blasts. The first encountered angel- Salchiel (#3)- manages to blast through it in two shots- much faster than Zeruel- though he doesn't use this hole to his advantage.
** Played more conventionally in ''End of Evangelion''. When Misato takes out several of the invading commandos, a close examination will reveal that the soldiers' vest were penetrated despite Misato only using a pistol.
* ''Manga/{{Berserk}}'' is an excellent example; soldiers wearing full plate armour might as well have put on paper mache, as both Guts and the demons he fights can tear through it with the greatest of ease. Guts explains in one scene that his sword is three times thicker and heavier than a sword that length would usually be, and this is before the Eclipse. After the Eclipse, Guts gets an even ''bigger'' sword that was designed for killing dragons.
** Even minor states are shown to equip many tens of thousands of troops in full plate. It's no wonder they had to make it tinfoil thin.
** Eventually subverted in a flashback story from Guts' lone mercenary days before he met the Hawks: A certain king wants his son to [[ARealManIsAKiller kill his first man]] in single combat before he goes to war and chooses Guts for the honor of being killed. During the fight Guts tries to stab through a weak point in the boy's full plate armor, but it is revealed to be an expensively-made ArmorOfInvincibility and totally blunts the edge of Guts' sword. It is hinted that Guts might have pulled it off if he hadn't been weakened by captivity, but luckily he remembers a special technique that Gambino had taught him for throwing an armored man to the ground.
* Von Jobina in ''Manga/{{Bastard}}'', full stop. He's always clad in armor from head to toe but, as the series' resident ButtMonkey, that doesn't stop him from getting his ass kicked around.
* ''Anime/WolfsRain'': The Nobles' elite guard have heavy full-body armour and shields with built-in disruptor rays. Yet even all that doesn't prevent several of them from being ''bitten'' to death by wolves. The wolves went straight for their necks, which had no plate armor to allow their heads to move easily.
** Justified, in that the armor was intended to protect agains the attacks of other human beings instead of an extinct animal.
* ''Manga/SaintSeiya'': Varies wildly. Sometimes armors play a vital role in a fight, sometimes a Saint gets his armor destroyed yet it doesn't seem to make him more vulnerable to attacks. The fact that some armors leave a lot of the wearer's body completely exposed remains consistently unimportant.
** Shiryu is an isolated case, as he always seem to end up naked (and blind too), but still wins most of his fights. In the fandom it is common to joke that a battle starring Shiryu is to take a while while he's still armored (and seeing). It is a common theme that Shiryu needs to outgrow the need for his armor to win a battle, not in small part because the armor gets in the way of his special technique of the week. On the other hand, he usually ends up the most battered of the team (Seiya gets battered a lot too, but since it is usually in his HardHead, he's fine).
* ''Manga/BlackLagoon'' subverts this in the Greenback Jane arc. One of the few hired guns to walk away from the siege (not counting the ones who had to swim) -- and the only one to do so under his own power -- is the one who wore a bulletproof vest.
* The heavily kevlar-armoured soldiers in ''Manga/ElfenLied'' die in scores when battling naked teenage girls - then again, said teenage girls have immense PsychicPowers that render them ImmuneToBullets and lets them pull people's limbs off with their mind.
* ''TearsToTiara'' : The enemy soldiers in the first arc may as well have been wearing Saran Wrap, for all the good their armor did them against the heroes' attacks.
* ''Franchise/{{Gundam}}'': Played with in every possible way. Usually averted in the beginning, where the titular SuperPrototype is usually invulnerable or at least highly resistant to enemy fire at the start of the war, the usually played straight as the enemy develops weapons capable of penetrating it. (Or, as Char demonstrated, no amount of armor will protect you from a sudden and violent change in acceleration.) Played straight and justified in Universal Century series from ''[[Anime/MobileSuitZetaGundam Zeta Gundam]]'' onwards, as no armor [[spoiler: except for exceptionally thick ones like on Scirocco's The O]] could stand up to sustained exposure to beam weaponry, so the main defense was not getting hit in the first place. Thus, most Mobile Suits built after the [[Anime/MobileSuitGundam One Year War]] period usually had ''less'' armor than previous designs.
** Reaches a head in CrossboneGundam, where it turns out that while regular armor (that is, built onto a Mobile Suit as a standard feature) won't do jack against beam weaponry, ''ablative'' armor works just fine, and the Anti-Beam Coating mantles the Crossbone Gundams use means they can charge in as they please. (The Crossbones were designed on the principle that Mobile Suits of this time focused on evading and defending against ''long-range'' beam attacks, with beam shields in common use, and were thus rather inept at close-in or melee beam attacks.)
** Series that include Mobile Armors generally follow this principle: whenever a Mobile Armor is introduced, it is very likely to be destroyed in that episode. One notable exception is the first [[Anime/MobileSuitGundamSEEDDestiny Destroy Gundam]], which took an entire story arc to take down, while a later battle against 7 of them takes about 2 minutes. Another exception is the [[Anime/MobileSuitZetaGundam Psyco Gundam]], introduced around episode 20, and didn't leave the show until episode 40. An improved version returned in Gundam ZZ only to get destroyed. Probably the only one that survives the series it appears in is the [[Anime/MobileSuitGundam00 Regnant]] - and even then, its main reason for survival was its {{Roboteching}} WaveMotionGun and StunGuns, not armor. Neither its FlawedPrototype Empruss, nor its AceCustom successor Gadelaza achieves this feat, however.
* ''Manga/{{Naruto}}'': Various characters wear plate armor (samurai, Choza, Choji, the first three Hokages), some wear what appears to be chainmail underarmor (Naruto, Jiraiya, Anko), the vests/jackets most ninja wear is ostensibly supposed to be a form of armor (looking a lot like the type of flak vests used by soldiers before [[BulletproofVest bullet-resistant vests]] were invented). They have only ever been shown to be useful on ''three'' occasions:
** A sand jounin survived a neck shot with a sword because his flack jacket's high collar absorbed the strike and trapped the blade. He then counter attacked with a wind blade that sliced through armor.
** Hinata's chainmail underarmor saved her life when [[spoiler:Pain]] tried to stab her in the heart with a spike, though she did require some healing.
** A samurai being consumed in [[HellFire Amaterasu fire]] was saved by having his armor taken off.
* In ''Anime/TengenToppaGurrenLagann'', the only one to ever wear armor is actually Thymilph, the first General of the Capitol. He's also the second named character to die [[spoiler: (Kamina being the first, despite the fact that he only truly faded away after performing a Giga Drill Breaker, thus avenging his own death).]]
* Possibly the only thing in all of ''Manga/{{Bleach}}'' to wear armor is the giant summoned by Sajin Komamura's Bankai. However, it seems to wear normal samurai armor in a world where other characters can, say, cut through all the buildings in a half-mile radius just by unsheathing their sword. The fact that Komamura takes any damage the giant does makes the [[TheWorfEffect worf]] notoriously strong with this one.
** Hardly Worfed. The only person able to damage him through the Bankai was [[spoiler: Tousen, another captain who had become a [[SuperMode Vizard]], and that put a graze on his arm.]]
** {{Exaggerated}} in the Vandenreich arc, where [[spoiler:Komamura's DeadlyUpgrade causes his Bankai to shed its armor... and makes it completely indestructible]].
* In animated short ''Anime/{{Kigeki}}'', the Black Swordsman cuts through an army of heavily armoured cavalry knights like butter. One of them he even slices in half down the middle.
* In ''Anime/RurouniKenshin'', Kenshin's sensei tells an armored giant opponent to remove his armor because it restricts his movements, weakening his offense, and that the false sense of protection from armor weakens his dodging/parrying skills.
** Taken to the extreme with Bright King Anji, whose special technique [[ArtisticLicensePhysics delivers two strikes so quickly in succession that an object's hardness is negated]], meaning it can literally destroy anything, no matter how hard.
* Subverted in the last episode of ''{{Anime/Noir}}'', where a Soldat [[NunTooHoly nun]] charges at the titular duo with a broadsword and proves to be horribly difficult to kill because of the armored breast plate she's wearing, and while she clearly feels the impact of the shots she keeps charging at them and finally has to be taken down with a knife to her neck, which wasn't armored.
* ''Manga/FairyTail'': Despite being armor-equipping being her primary magic, Erza later in the manga seems to do much better the less armor she equips, as her stronger opponents tend to break through them very easily.
* ''Manga/{{Gamaran}}'': Armors (usually chainmails) are pretty effective against swords, but more often than not, the sword users (99% of the times, Ogame Ryu Members) will find a way to pierce the mail anyway. In Iori's case, is because he's so powerful that even his slashes can break a chainmail.
* Katanagatari: Subverted in at least one case - one of the Deviant Blades is a suit of armor that is not only impenetrable, but actually designed to defeat techniques specifically designed to penetrate armor. It's only defeated by the hero getting creative.
[[/folder]]

[[folder:Comic Books]]
* In ''ElfQuest'', when the elves fight the trolls for the Palace, the rogue half-troll Two-Edge set the elves up with plate armor. It does, in fact, even the odds - but even so, many die, and one character spends two good pages on the horrified realization that armor doesn't make him invincible (not that he was in much danger by that point, as co-creator Richard Pini had taken a shine to the lad and even vetoed an earlier dramatic death for him).
** It is not so much that this trope is played straight, but merely demonstrates that despite the considerable advantages of arming your foot soldiers in full plate armor, it's not impenetrable, especially not when your enemy is a hulking, raging troll
* In Frank Miller's ''[[ThreeHundred 300]]'' features Spartans going bare-chested into battle, with little but loinclothes and bracers as armor besides their shields. Miller, with his background drawing spandex-clad superheroes, was more comfortable drawing human physiques, and thought the Spartans in armor looked too weird. In reality, Spartans wore heavy bronze armor, including breastplates, which was a major advantage over the cloth armor and wicker shields of the Persian soldiers.
* In his first few years, PrinceValiant deliberately outfitted himself relatively lightly, to allow himself greater speed in combat. Somewhat justified here, as Val isn't even 18, going up against experienced, fully-armored knights. If he had a full loadout, he would be easily out-muscled. Using his maneuverability to stay ahead of his opponent is his only chance.
[[/folder]]

[[folder:Film]]
* ''TheHurtLocker'': Played relatively straight; a bomb squad worker is confronted with a bomb so big it completely fills a car trunk. He chooses to take off his armor at this point, noting that he might as well work in comfort, since the suit won't save him from a blast that big. The armor's weaknesses are demonstrated at the start of the film when the DecoyProtagonist is in full armor and running away from the bomb when it detonates, but is still killed by the blast. Also inverted; wearing the armor ''does'' save one life in the course of the film.
** The film makes several references to a 'kill radius'. While inside that zone the blast of an IED will be so forceful even their reinforced armour is of little protection. The suit's purpose is to protect the wearer while between the kill radius and minimum safe distance, and ''maybe'' save their lives while in the kill zone.
* The ''Film/TheLordOfTheRings'' films have interesting combination of both aversions and invocations of the trope.:
** Legolas and Aragorn wear no armor through all of fellowship and slaughter goblins and Uruk-hai with half plate armor and heavy shields by the dozens. At the Battle of Helms Deep in ''Literature/TheTwoTowers'', Aragorn wears a chain mail hauberk while Legolas has only bracers and leather paldrons. In this same battle, Théoden, wearing the best armor of anyone in Rohan's forces, gets wounded in the shoulder.
** The Uruk-hai berserkers take this trope to the max. They wear nothing but helmets and chainmail loincloths, yet are deadly against the defending Rohan forces. In a slight aversion, the helmet of one of them comes in handy while he is fighting Gimli, as Gimli had to hit him twice to take him down.
*** In ''The Fellowship of the Ring'', Merry and Pippin take several heavily armored Uruk-hai down by throwing rocks at their heavily armored heads. [[note]] Sort of TruthInTelevision, as medieval helmets, ''on their own'', offer limited protection against blunt-force blows - the helmet prevents cutting edges from making a mess of your head, but without some form of shock-absorbing padding it does next to nothing to mitigate the effects of a few pounds of steel (or rock) smacking into it at speed.[[/note]]
** The soldiers of Gondor especially have rather useless armor. In one scene in the Extended Edition of ''Return of the King'', an orc arrow goes straight through a random soldier's breastplate. In real life, steel breastplates would deflect an arrow from that range, especially from such a flimsy shortbow.
* In the second movie based on ''Film/ResidentEvil'', [[GodModeSue Alice]] takes down a fully armored Umbrella Squad while wearing only skimpy clothing. Jill Valentine also wears a skimpy outfit through most of the film and never sees fit to cover up a bit to guard against zombie bites.
* In ''Film/{{Hero}}'', the Emperor wears armor at all times to protect himself from assassins, but whenever he's confronted by one, they can kill him at will.
* ''Film/StarshipTroopers'' where the MI's armor vests provide no protection whatsoever. Bug claws, their ''own weapons'', and a high-velocity shovel-yes, a ''shovel''-penetrate without any trouble at all. You have to wonder why they even bother with armor...
** Note that in the [[Literature/StarshipTroopers book]] and [[Franchise/StarshipTroopers strategy board game]], armor worked extremely well. Indeed, the book is the PoweredArmor TropeCodifier for Western culture. Of course, [[Film/StarshipTroopers the film]] was intentionally designed as [[SpiritualAntithesis the polar opposite of the book]] in terms of message, characterization, and theme, and has been accurately (if snarkily) described as "based on the blurb on the back cover of a book by Robert Heinlein."
* ''Franchise/StarWars'':
** Many people make fun of the Stormtroopers' full body armor, which does not seem to protect them hits by blasters or light sabers. However, no Stormtroopers are ever shown to go down when a laser blast hits a wall near them, while some unarmored rebels and Imperial officers do. Thus, it might be shown that Stormtrooper armor does protect against shrapnel, [[TruthInTelevision which is one of the main functions of real body armor in today's ballistic age]]. In addition, after a few battle scenes, Stormtroopers who got hit directly by blasters (at rather close range) ''do'' indeed get up; they're wounded and have to be helped by teammates, but alive. The same doesn't apply for the unarmored rebels. Stormtrooper armor also seems to resist penetration from arrows and absorb the impact of rocks on Endor [[RockBeatsLaser (though the wearers]] ''[[RockBeatsLaser still]]'' [[RockBeatsLaser went down anyway]]). [[AllThereInTheManual Other sources]] state the armour should still absorb most of the impact from a bolt if it fails to avoid penetration. Despite this, the armour is never actually shown stopping anything visible.
*** Also consider the relative calibers of weapons involved. Han Solo readily mows down Stormtroopers with his pistol, but said pistol is a HandCannon by GFFA standards. The Rebels tend to prefer such heavy blaster pistols for exactly that reason. As for lightsabers, they go through basically anything that isn't [[{{Unobtainium}} cortosis, phrik, Mandalorian Iron]] (the last DependingOnTheWriter), or [[LikeCannotCutLike another lightsaber]].
** One plausible fan explanation is that Stormtrooper armor is about as effective as a bulletproof vest in real life--getting shot while wearing it hurts like hell and may break some ribs or cause you to fall over from shock, but at least it'll save your life. The camera doesn't linger on shot Stormtroopers, so for all we know they could be getting to their feet a few minutes later and limping off to the medic. While I'm at it, armor designed to absorb/dissipate energy bolts while remaining lightweight and long-wearing might not be equipped with heavy plating and padding to stop rocks, sticks, and knives.
** The most common fan interpretation of the armor failing on Endor is that while armor can protect one from rocks and sticks, that won't matter for long when the enemy is throwing hundreds of them onto you.
** Darth Vader deflects laser shots with his armored hand, though it's never explained in the film whether this is a function of his gauntlets, Force powers, or both. The novelization states it's the gloves, but Force Deflection is a power that allows a Force-user to block blaster bolts with their bare hands.
** Somewhat highlighted in the first film, where Han and Luke steal Stormtrooper armor so as to walk the halls of the Death Star undetected. As soon as they free Leia and escape the trash compactor, they immediately dispense with the armor. Once its use as camouflage is rendered irrelevant, so is its use as armor. Presumably they weren't properly trained in its use, which the men guarding the Death Star presumably are. Alternatively, they may have been trying to avoid friendly fire during the escape.
** In the EU, Stormtrooper armor usually works better. In ''[[ComicBook/XWingSeries Rogue Squadron]]'', Corran Horn credits the stolen armor he was wearing with saving his life after he gets shot (he spends a week in a bacta tank, but believes he would have been dead without the armor). The armor is also shown to be basically impervious to kinetic penetrators in the ''Literature/YoungJediKnights'' series: a metal spear is thrown at an armored character hard enough to lift him completely off his feet and throw him a few meters backward into a wall. The armor comes out with a small nick; the character is sore but otherwise unharmed.
** Then there's [[ProudWarriorRaceGuy Mandalorian]] battle armour, which, [[DependingOnTheAuthor depending on who's writing]], can be anywhere from slightly more effective than Stormtrooper armour to being [[BeyondTheImpossible virtually impervious to lightsabers]]. Considering the Mandalorians' long history of fighting Jedi, that second part can be justified as they found one of three materials in the universe that can withstand lightsabers.
*** This part is justified in universe as Mandalorians of different era wear armor made out of different materials. The heavy armor that is lightsaber resistant tends to be very heavy armor whereas the mass produced armor likely IS made out of the same materials Stormtroopers use, but is much cheaper and highly mobile.
** Fighter DeflectorShields also qualify. Everywhere except the films, an X-Wing's shields can repel TIE fighter lasers for several seconds. Not so in the movies, where the X-Wing is destroyed if it's hit squarely ''once''. There would be a partial justification for this in A New Hope, where they're told to switch their deflectors on "double front". As anyone who played X-Wing or its successors will point out, this dumps all your shields forward, leaving your rear uncovered. However, this was later followed by another pilot ordering "Stabilize your rear deflectors." when they anticipated a fighter attack. Further, the "double front" explanation falls utterly flat in light of the other films.
* Played straight in ''Film/ThreeHundred'', which mimics the [[ShirtlessScene bare-chested]] Spartan battle outfit found in Frank Miller's graphic novel.
* ''Franchise/TheChroniclesOfRiddick'': Necromonger troops wear heavy, bulky suits of what looks suspiciously like [[http://en.wikipedia.org/wiki/Maximilian_armour 16th-century Maximilian armor]], which have no apparent damage resistance whatsoever.
* All cops in ''Film/TheFifthElement'' wear bulky armor that does absolutely nothing to stop bullets.
* Most of the troops in ''RedCliff'' wear various forms of armor which provide no protection whatsoever. Master Archers who (because this is a JohnWoo film) can [[ImprobableAimingSkills bullseye any target they can see]] shoot enemy troops right through their breast plates, not even bothering to aim a few inches higher to hit exposed necks. The senior generals frequently cut off limbs with a single stroke, not even slowed down by the heavy metal armor their targets are wearing.
* In ''Anime/FinalFantasyTheSpiritsWithin'', the soldiers wear all of this heavy armor that does nothing to protect them from Phantoms.
* In ''BattleLosAngeles'', the Marines' armor is ineffective at stopping the aliens' weapons, as the incendiary rounds they have burns right through them and they impact with enough force to consistently throw people off their feet and backwards.
* In ''Film/{{Dredd}}'', Judge armor can't even seem to stop a pistol round, much less anything else. Dredd himself gets hit with an armor-piercing round which would logically go through, but his partner get hits with the pistol.
** Earlier, Dredd rebukes the rookie about her leaving her helmet on her bike instead of on her head. She replies that the helmet makes it difficult to use her PsychicPowers. Dredd replies that a bullet to the head would make that difficult too. Given how ineffective their armor is, it's unlikely their helmets would be much better. For his part, Dredd never takes his helmet off, as a nod to the comic, unlike the film ''Film/JudgeDredd''.
* In ''Film/IronMan3'' Extremis-enhanced soldiers cut through Tony's armors like butter, as their bare hands can generate heat of up to 3000 degrees Celsius. It also doesn't help that most of the versions of the armor we're shown during the battle are half-baked prototypes which Tony didn't bother perfecting before moving on to the next idea.
* Mostly averted in John Boorman's ''Film/{{Excalibur}}'' where the very heavily armored knights really do have to pound the living Hell out of each other to have any effect in a fight.
* In the climax of ''Film/RobinHood1991'', outlaws [[ItMakesSenseInContext in carnival costumes]] are beating up fully armoured soldiers with ease.
[[/folder]]

[[folder:Literature]]
* ''{{Dragaera}}'': Justified, as metal armor is a great target for sorcery. This is a bit of an after-the-fact handwave by author Steven Brust, who loves the cloak-twirling romances of Dumas and modeled his world after them, complete with the general lack of armor. We do see that some leather armor is used during war.
* Mostly {{Averted}} in ''Literature/TheDresdenFiles''. Armor, especially [[ColdIron iron]] and spelled armor like Harry's many trenchcoats, are extremely useful and Harry and co wear them even when it's extremely uncomfortable - and it saves their lives many times over.
** Once, [[spoiler: Michael's]] steel and ceramic plate armor layered with kevlar actually hurt him - the bullet had enough velocity to get in, but not out, and shredded his insides. He survived, but barely.
* Practically none of the ''{{Redwall}}'' characters wear armour, except Martin and the Badger Lords. Tsarmina's {{Mooks}} were an exception, but the armour was described as "cumbersome" and hindered more than it helped (particularly when [[spoiler:the heroes flooded the castle]]). Possibly justified because mice and other small mammals have slightly tougher skin than humans, their fighting style in the books is based more on speed which armour would hinder, and going by the flexibility of most rodent and mustelid skeletal structures it would be ''really'' difficult to make armour to fit them without severely restricting movement.
** Also the Redwall forest is not particularly industrialised - something of a lack of iron mines and foundries to provide the wherewithal for armour to be common. Note also that even swords are pretty rare in the books, with most combattants using spears, clubs and knives as melee weapons. Not a great smithing tradition, you might say.
* Creator/DanAbnett's ''TabletopGame/{{Warhammer 40000}}'' novel ''Literature/BrothersOfTheSnake'' discusses and averts this. When Space Marines fight a foe that they can see only with the naked eye, they open their visors with explicit commentary about how it makes them more vulnerable in one sense. Indeed, [[RealityEnsues several of them die because of it.]]
** A number of other ''TabletopGame/{{Warhammer 40000}}'' novels fall back on playing it straight, especially the Horus Heresy series (where hundreds of power armoured supermen get cut down by necessity, usually by guns that [[GameplayAndStorySegregation wouldn't actually penetrate the armour in the game itself]]) but notable exceptions are skirmishes in the Abnett Eisenhorn and Ravenor series, where even basic armour is a major obstacle to the protagonists, and Literature/CiaphasCain[[note]]'''HERO OF THE IMPERIUM'''[[/note]] who has his life saved on several occasions by his battered set of misappropriated carapace armour.
* ''VideoGame/PerfectDark'': The first novel (yes, novel) notes the uselessness of armor in the games. The evil company is so huge that it's offensive division is constantly outclassing the defensive division. Nobody is telling [[RightHandVersusLeftHand the right hand]] to stop inventing guns that can chew through the bulletproof vest [[RightHandVersusLeftHand the left hand]] issues the company soldiers.
* Partial credit for the Thalesians in David Eddings' {{Elenium}} and {{Tamuli}} - Thalesian knights go to war in chainmail, not in full plate, as Thalesia is full of deep rivers and streams, making platemail more of a hazard than a help. A chainmail shirt is easily removable, whereas by the time you have a chance to get a full suit of riding armour off, you'll have drowned.
** Funnily enough, a full suit of riding armor incorporates quite a bit of chain, is about as heavy as a full chainmail and is easier to remove under water than chainmail. If we were looking at normal plate, it would be lighter than chain, and way easier to remove. Removing chain is about pulling it a bit over your head, and wriggling out of it, while gravity pulls it down, which is way harder to do underwater than to cut the straps of the plate parts that hinder swimming.
** To Khalad's assertion that he could create a crossbow capable of firing a bolt several miles, Vanion shakes his head and forsees the obsolescence of the knight in full armour.
** A literal case happens at the end of the Elenium, when they encounter several undead Zemochian knights. The Zemochians have never understood that armor is supposed to ''protect'' you, and assume it's there for intimidation purposes only - so they wear ScaryImpracticalArmor that hinders their movement and has countless weak and blind spots, and with spikes that threaten to cut or impale the wearer if they make a wrong move.
** Played with: Adus' armor, which might have saved him if it had ever been fitted to him. As it was, there were more than enough unarmored gaps for Talen's dagger to slide through. (Whether Adus had sufficient brainpower to put armor pieces on correctly is another question.)
** Also played with in the final confrontation between Sparhawk and Martel. Martel's armour is very far from useless, but it's style and ornamentation make it far heavier than the suit worn by Sparhawk, and causes Martel to lose his wind quickly.
* In the WheelOfTime, many characters forgo armor either because they fight with magic, or because they're trained swordsmen, not soldiers, and the armor would only slow them down. Besides them, this trope is largely averted for mundane weapons. Though obviously magic fireballs and lightning aren't terribly impeded by steel.
* Literature/ASongOfIceAndFire takes this trope, plays it straight, subverts it, and does everything in-between. Characters survive from armor's protection, die from it's weight, and have to calculate how much armor to use along with how it's advantages and disadvantage apply to a certain situation.
** Victarion Greyjoy uses the advantage of armor to it's full effect whilst fighting out at sea. When boarding any enemy vessel he notes most forgo heavy plate for fear of drowning should they fall into the sea. Victarion has no such fear. Notably it's only when he encounters another warrior brave enough to don armor like himself, something Victarion [[WorthyOpponent respects]], does he find a challenge.
** Prince Oberyn Martell only wears light armor when facing "[[NamesToRunAwayFromReallyFast The Mountain]]", Ser Gregor Clegane, in a TrialByCombat. This is actually a sound strategy given armor wouldn't be all that useful against the ridiculous brute force of his opponent. Instead the Red Viper opts uses his superior speed to his advantage. [[spoiler: Whilst he inflicts mortal wounds on the Mountain, the Prince lets his guard down and is killed nonetheless.]] This is basically the same strategy used, with rather more success, by Bronn during Tyrion's TrialByCombat in the Eyrie.
* Literature/TheOnceAndFutureKing sometimes plays it straight, such as when Lancelot kills [[spoiler: Agravain]], but usually inverts this. When fighting unarmoured peasants on the battlefield, being an armoured knight is like using an invincibility hack. White includes one passage where a knight was none the worse for wear from being unhorsed and mobbed by spearmen. Indeed, after his comrades rescued him, it was actually found that he fought ''better'' because now he had lost his temper.
* [[SubvertedTrope Subverted]] in TheTraitorSonCycle by Miles Cameron. Armor is one of the few things that mankind has to protect them against the forces of the Wild. More than once, a man's life is saved solely due to the fact that he is wearing armor... or dies painfully because he was not. The most telling example is of a HoldTheLine situation where a single man in medium armor is forced to hold a breached gate against an incoming swarm of boglins. The armored man takes many blows during the battle, but since boglins are armed with only stone weaponry and have no strategy asides from ZergRush, which isn't very useful in an extremely narrow area, he's able to hold them off for quite some time. One unarmored man jumps in and tries to help him, and within three seconds, the man who jumped in is injured, grabbed by boglins, pulled into the onrushing mass, and is eaten alive.
* Subverted in ''Franchise/StarWarsExpandedUniverse'' series ''Literature/NewJediOrder'': Yuuzhan Vong armor is incredibly tough, they can withstand blaster fire, and even lightsabers. However the Vong aren't always full armored and the regular {{Mooks}} don't wear helmets.
** Then there's the matter of the Yuuzhan Vong's [[OrganicTechnology living armor]] having ''allergies''.
* Justified in SergeyLukyanenko's ''ALordFromPlanetEarth'' with the [[SharpenedToASingleAtom planar]] [[AbsurdlySharpBlade swords]] being the main weapon of combat. The blade can cut through anything without slowing down with LikeCannotCutLike completely averted (swordfighting techniques are focused on avoiding getting your own blade cut while timing your strikes to cut the opponent's blade). Combatants can wear special armor, but even that can't prevent a blade that sharp from cutting. The main goal of the armor is to harden at the point of the cut in order to allow the wound to heal (which takes about 3 seconds given how fine it is). A wound to the heart, though, can never heal, as the heart beating will expand the tiny cut into a gaping hole. An additional effect of the armor hardening is to try to [[BareHandedBladeBlock hold the sides of the blade]], keeping the opponent from moving it. The protagonist accidentally figures out how to defeat the latter function, killing the BigBad of the first novel in the process in a gruesome fashion.
** In the third novel, the protagonist dons an advanced nano-armor that can take any hit and will protect the wearer and self-repair (being composed of nanites). However, the nano-armor still can't stop a planar blade, although it, presumably, can function like the normal dueling armor. When the protagonist faces off against his Fang counterpart wearing their equivalent of the armor, the two armors destroy each other nanite-by-nanite.
* Subverted and PlayedWith in ''Literature/TheStormlightArchive'', where knights wear Shardplate, magitek PoweredArmor capable of shrugging off anything short of a [[AbsurdlySharpBlade Shardblade]] or sustained attacks by almost entire armies. Two knights equipped with full Plate and Blades are able to survive against an army that outnumbered their own greatly for the better part of a day, albeit with horrific casualties among their more conventionally armored allies.
[[/folder]]

[[folder:Live Action TV]]
* ''Series/StargateSG1'' featured all kinds of armor, almost none of which were actually useful. The kevlar worn by the Tau'ri (humans from Earth) does nothing to stop any of the weapons they face (in fact, it's been stated that it actually makes things worse when it comes to [[BoomStick staff weapons]]). It's worth noting that SG-1 itself doesn't bother with armor yet seems to have the lowest casualty rate of any SG team. Jaffa armor starts off being effective, a situation that is changed once the Tau'ri replace low-velocity [=MP5s=] with P90s and armor-piercing ammunition, instantly turning initially invincible juggernauts into generic {{mook}}s.
** "Heroes," the same episode that mentioned the kevlar problem, also demonstrated an experiment in new anti-Jaffa armor inserts, which let Sgt. Siler take a full staff blast in the gut and only get knocked back and lightly set on fire. This armor is credited with [[spoiler:saving Colonel O'Neill's life when he's shot in action]].
** The Jaffa in the original movie were more ceremonially dressed, and didn't wear armor, allowing O'Neill to take one down with a burst of submachine gun rounds into the exposed gut. The TV show had to tone down the violence though, and had armored Jaffa largely because bullet impacts on armor are less graphic than bloody chunks getting shot out of somebody. So the armor was more to protect the show's rating than the Jaffa themselves.
** Realistically averted in one episode where SG-1 is doing an operation on Earth wearing bulletproof vests. Col. Simmons shoots O'Neill twice in the back. One bullet is stopped by the vest and breaks a rib, the other hits him in his unarmored arm.
---> '''O'Neill:''' I want sleeves on my vest.
** Also averted with Anubis' Kull Warriors, whose armour was friggin' invincible to pretty much all the conventional weapons the Tau'ri could bring to bear, even heavy explosives. However, like kevlar, it does little to stop a dart gun with a needle small enough to go between the weaves.
** Ori warriors also wear armor that appears to be more for show. Then again, it's not clear how that armor faces against energy weapons, as we mostly see it fail spectacularly against [=P90s=]. Of course, the Ori hardly concern themselves about the lives of their worshipers.
* ''Series/KamenRiderKabuto'': Each Rider has a bulky "Masked Form" and a sleek "Rider Form". Allegedly the Masked Form is tougher and better protected, but one cannot help noticing that the Riders invariably cast it off at the first opportunity and finish off the monster in Rider Form.
** The Riders in that series need to shed the heavier armor to use their finishing moves. Yeah, even the ones whose finishers use almost-completely external equipment (Drake and Sasword). It's only in their leaner modes that they can move at hyper-speeds, too, and not having anybody who could counter the monsters' ability to do that themselves was why ZECT was losing so badly before the Riders started seeing action.
* {{Lampshaded}} in ''Series/{{Heroes}}''. As Mr. Bennet is putting on a Bulletproof Vest, he admits that it'll be useless against the supervillains he's about to face, and he's only bothering with it in order to keep up TheMasquerade.
* Averted in ''Series/{{Firefly}}''. In the pilot, Zoe wears a bulletproof vest to the meeting with Patience, [[GenreSavvy expecting violence to ensue]]. When it inevitably does, she takes a bullet to the chest and is knocked flat and apparently unconscious for a couple minutes, but is otherwise unwounded. In [[Film/{{Serenity}} the movie]], the Operative likewise wears full body armor to his meeting with Mal, and it likewise saves his life when Mal loses his temper.
** Seemingly played straight in the flashback to the Unification War in the pilot when Mal shoots an armored Alliance soldier. Under closer analysis it's muddier: Mal fired several shots before the guy fell over, and he was using a full size assault rifle. Also, given that the Alliance equips its troops with body armor as a matter of course, Mal's rifle could have been loaded with armor-piercing rounds. Or the guy might have been knocked unconscious by the impact without the bullets penetrating.
* While normally played straight in ''{{Andromeda}}'' (with personnel armor, that is, starship armor works just fine), Gennite soldirs have "photo-reactive" armor that is show to be quite resistant to handheld weapons.
** One episode also mentions that most handheld weapons use guided projectiles. Thus, they can be fooled by special bracelets that throw up interference.
** considering every weapon is some kind of plasma, laser, or coil gun, armor generally seems useless. the Electromagnetic Bracelets are used as an excuse for some defense.
** [[NietzscheWannabe Nietzschean]] bone blades (which grow out of their forearms) can also go right through armor. This is similar to RealLife cases of bulletproof vests being incapable of stopping a blade.
* On ''Series/SpartacusBloodAndSand'', Roman soldiers in full armor seem, if anything, more hindered when fighting against nearly-naked rebel gladiators. In one instance Spartacus even knocks a helmeted soldier unconscious using another soldier's helmet! The rebels meticulously collect any weapons they can from fallen soldiers, but never bother with their armor or helmets, presumably because they did not do their deceased wearers any good.
** Another reason would be that, in the heat of battle, you wouldn't want to be wearing the enemy's uniform. The rebels do start wearing more castoff and modified Roman armor as the series progresses, especially in War of the Damned.
* Averted in ''Series/GameOfThrones'' when Jorah Mormont, wearing plate armor, fights against a more agile but unarmored Dothraki warrior. The Dothraki lands a blow but his arakh gets stuck in Mormont's armor and doesn't hurt him; Mormont uses that moment to kill the Dothraki.
** Played stunningly straight in season 4, the heavily armored Champion of Meeren is easily dispatched by a Dothraki arakh and later on Ramsay Bolton manages to kill several fully armed soldiers while half-naked.
** But also averted in Season 4 when the Hound, unimpressed with her water-dancing technique, invites Arya to stick her fencing blade into him. The sharp point stops against the armour and the Hound knocks her down, pointing out that her swordfighting instructor got himself killed because his opponent had little skill, but had armour and a big f**king sword.
* It's a gimmie that the Sheriff's men in any series of RobinHood will be issued with almost completely unarrowproof armour. In the creators defence, the mooks are often shown with what a well equipped soldier in the reign of King Richard might wear. It's just that the outlaw's longbows shouldn't be around for another hundred years or so.
* Averted in season 3 of Breaking Bad when the Cousins use bullet proof vests [[spoiler: in their mission to kill Hank. One of them takes several handgun bullets to the chest and walks away unharmed. [[BoomHeadshot Too bad it didn't cover his head.]]]]
[[/folder]]

[[folder:Multiple media]]
* In ''Franchise/{{Bionicle}}'', armor is mostly a part of the characters' anatomy, but unless it's explicitly made of some super-rare and super-strong material (like protosteel), or is somehow connected to their powers, does little to protect their wearers during battle. This is because there rarely is any physical combat, most of the attacks are based on powers that make protective armor not only useless, but at times disadvantageous. And even so, the armor almost always leaves many fleshy bits uncovered. But even when armor does prove useful, there usually is some contrived story reason why they have to take it off (such as with the Exo-Toa mechs that blocked the users' powers). In a nutshell: armor is essential for day-to-day life, but doesn't do much during battle. This is however averted in the Bara Magna storyline, where the fights are physical and armor is very important.

* ''Roleplay/DestroyTheGodmodder'': Zigzagged, having armor gives entities no bonus, but armor alchemies stand out for being the only clothing alchemies to actually do anything.

[[folder:Tabletop Games]]
* In ''TabletopGame/DungeonsAndDragons'' armor is the ''easiest'' way to get higher Armor Class, but it tops out at a certain point, and using the really heavy armor [[MightyGlacier comes with drawbacks]] -- including penalties to many physical actions. Some characters are prohibited from using their special powers while wearing armor that is too heavy, or wearing any armor at all. In versions 3.0 and beyond, armor is also judged worthless when determining whether "touch attack" spells hit, which generally confer the most devastating effects in the game. Ultimately there are many magical alternatives to armor that will increase your Armor Class at a greater cost, but without all the drawbacks.
** Monks in particular embody this trope since they lose almost all of their abilities if they put on anything heavier than a wool shirt. Additionally, they gain a bonus to Armour Class based on their Wisdom and level. It is fairly easy, magic aside, for a monk to quickly outstrip even the heaviest armoured fighters.
** In the 3.5 Edition, many players feel that Armor Class itself, encompassing all types of defense, is useless because most monsters have a high probability of hitting you anyway, due to their huge Base Attack Bonuses granted by racial hit dice, their often enormous strength, and the fact that their natural attacks do not follow the same degradation formula that weapon users do. It does limit the extent of Power Attack that can be levied against players and certain creatures do make extensive use of weapons, meaning that their last few hits have a lowered chance of hitting you, but it doesn't change the fact that against anyone who doesn't use weapons will tear a player character apart and there's nothing his or her armor can do about it. Players ultimately discovered that [[TheLawOfDiminishingDefensiveEffort the best defense is a good offense]], sacrificing Armor Class for the sake of increased attack power, effectively turning most characters into {{Glass Cannon}}s.
** As early as level 7 (of 20), the right combination of magical effects (decoys and percentile "miss chance" rolls) can provide just as much protection as an arbitrarily high armor class. These effects are most readily available to Sorcerers and Wizards, the characters who suffer the most from wearing actual armor.
** With 4e armor becomes more of a relative thing because characters add half their level to their armor class while adding half their level to their chance to hit. While it can create problems, it tends to nicely simulate films of the fantasy genre: Achilles in ''Troy'' can wade through soldiers by slashing throats and otherwise finding the weak spots in their armor, while Aragorn and Legolas don't get hit during a mass melee despite their light armor.
*** Additionally, if a character is wearing light or no armor they can add their DEX ''or'' their INT bonus to their armor class. So now Gandalf, even as a 5th level wizard, is all but impossible to hit for orcs due to his awesome intelligence.
*** At the very high levels, a character who wears no armor (and uses Dex or Int to boost AC) will eventually outpace the heavily-armored characters. Various fixes have been created and proposed to fix this issue.
*** Also, not to forget, 4e Essentials allows a Warlock to wear Chainmail without any kind of backdraw in battle.
** In D&D in general, there is a rule about heavy armor and sleep. If a character sleeps while wearing heavy armor, he'll wake up more exhausted than when he went to sleep.
*** Which is [[TruthInTelevision truth in television]], as any armor is not designed for comfort at the best of times and is downright ''uncomfortable'' when lying down. You don't sleep well wearing it.
** Armor in D&D 3 ed. is essentially this. In reality, heavy armour provides protection at a expense of mobility. In D&D armor protects the character from being hit but does nothing to attacks that connected. It also places a cap on dexterity bonus rendering the character easier to hit. It means that very nimble character is usually better off not wearing most armors. Which is peculiar as D&D 3 ed. incorporates mechanics for non-armor damage reduction.
*** A smart DM may avert that version by a describing failed enemy attack roll on a heavily armored target as "the blow bounces off harmlessly" or some such.
* One of the official ''TabletopGame/{{Pathfinder}}'' supplements has a barbarian variant that grants the ability "Naked Courage." It grants the character a bonus to AC when not wearing armour. Granted, it's a fairly small bonus.
** ''Pathfinder'' also published the "NPC Codex", which provides official stats for the game's iconic characters. With her spells running, Seoni (the sorceress in the slinky red dress) officially has a better armor class than any of the heavy-armor wearing melee characters.
** Firearms, if allowed, render armour useless at close range since they are treated as touch attacks.
* ''Franchise/{{Star Wars|Expanded Universe}} d20 had armor that really was useless, unless you were already almost dead. It provided damage reduction only when you were out of vitality points or against a critical hit, when damage went to wound points. So for most of a battle, all most armor did was provide a situation bonus to one ability and an armor check penalty to certain skills. ...yay? It also denied you your class-based AC and limited your max Dex Bonus. This could be designed to reflect the stormtrooper armor's uselessness.
** In ''Franchise/{{Star Wars|Expanded Universe}}: Saga Edition'', characters gain bonuses to their Reflex Defense (the defense that keeps blaster bolts hitting you) from armor or a [[StatisticallySpeaking level-based bonus]], and they don't stack. At higher levels, it's better to go into a fight naked, rather than wearing the heaviest protection you can find. However, it isn't played completely straight as the bonuses to Fortitude Defense from armor do stack and with the right talents, you can get them to stack with the Reflex Defense as well.
* One of the most notable examples in the ''TabletopGame/{{Warhammer 40000}}'' background is the standard issue flak armour of the Imperial Guard - a bulletproof, heat and shrapnel resistant uniform with potentially extra armoured-areas by our standards... that is generally useless against most of the weaponry of the other species within ''TabletopGame/{{Warhammer 40000}}''. The PowerArmor worn by the SpaceMarine Mascots, on the other hand, is generally an aversion. Most weapons have a better than even chance of bouncing off harmlessly, and the even more powerful Terminator Armor is protection against anything short of Heavy Anti-tank weaponry or plasma weapons, and for dealing with such weapons, [[LuckilyMyShieldWillProtectMe Storm Shields]] and [[EnergyShields The built in energy shield]] of terminator armor still provide reasonable protection.
** Admitedly, the weaponry used by other species includes, but is not limited to, [[{{BFG}} armor-piercing rocket-propelled grenades]], [[AbsurdlySharpBlade mono-edged high-speed shurikens]], [[AbnormalAmmo armored flesh-eating acidic worms]] or [[EnergyWeapon droplets of superheated plasma]]. And that's just what the line infantry uses. Specialists and other elites can, and often do, pack much deadlier weaponry. On the other hand, flak armor provides quite decent protection against lasbolts, bullets (even high-caliber ones) and most conventional melee weapons and its one of the best armors available to starting characters in the [[DarkHeresy RPG]] Unfortunately in the tabletop game, the only faction to use such weapons is usually the Imperial Guard themselves. Granted though, in 40k lore the Imperial GUard is usually fighting traitorous planetary defense forces or Imperial Guard regiments turned to Chaos.
** the Imperial Guard are intentionally a RedshirtArmy, so they follow several tropes of skilled and decently equipped soldiers being useless. Medium and high levels of armor provide good protection, but light armor is penetrated by the basic weapons, not to mention heavy and armor piercing ones.
** Dark Eldar wyches play this trope to a tee, with a superhuman athleticism that means the less armour they wear, the more they've practised to avoid needing it (and wearing less armour allows you to be more agile). A wych who goes into battle [[FullFrontalAssault wearing nothing]] will mess your heavily-armoured troops up badly.
** Terminator armor is dramatically nerfed in ''TabletopGame/SpaceHulk'', where Genestealers easily shred it (in the normal game, they just have a rule that reduces its protection from "block 5/6th of attacks" to "block 1/3rd of attacks", 1/6th of the time).
* In ''{{Exalted}}'', averted at the low levels, as good armor vastly increases your survival chance in a fight--aside from the fact that the rules specifically state that the only reason to wear [[HelmetsArehardlyHeroic a helmet]] is if you don't think your hairstyle is [[RuleOfCool cool enough]]. Played straight at high levels, as there are enough MartialArtsAndCrafts abilities that only need to touch you to mess you up in ways ranging from petrification to ''having your soul fall off'' that characters will mostly be depending on magically-powered defenses, rendering armor somewhat redundant.
** Armour is a lot more useful with the 2.5 revisions, which halved the cost in Artifact dots for a decent suit and reduced weapon damage across the board. It's still vulnerable to bad-touch effects, though.
* Armor in ''{{GURPS}}'' very roughly mirrors the rise and fall in armor usefulness in reality, with available armor playing catch up early in each TL. This ceases to be the case at TL 12 where you can buy guns that delete people from reality, which renders armor rather pointless.
** In 4th Edition {{GURPS}}: Spaceships the rules have led to the comparison "eggshells armed with hammers".
* ''TabletopGame/{{FATAL}}'' has such things as stabbing attacks (which hurt rather a lot even through armour) and magical armour that actively ''reduces'' your Current Armour stat. And that's not going into the armour that kills you and raises you as a zombie serial killer, armour that simply kills you, or armour that fills your crap with kitten seeds.
** Even that's not as terrible as the armor that turns you into [[DudeNotFunny grotesquely offensive racial stereotypes]] from countries or ethnicities that supposedly don't even exist in the setting. It ain't called "the worst RPG ever made" for nothin'.
* In '''{{Ammo}}''' almost every player character has some sort of manga-inspired power, but only a few will be even moderately defensive, or last more than a few battle turns. Armors, both passive or PoweredArmor, are ''required'', even against the weakest foe. Between normal unprotected humans a round kick is often lethal, and two is overkilling.
* For WildTalents this is a ZigZaggingTrope. Armor is both hugely important and easy to circumvent, much like in real life, and attack powers with Non-Physical can ignore most armor outright. With that said, it's also possible to build armor that normal weapons and even many superpowers can't penetrate, and stacking all three types of armor (light, medium, and heavy) will make you pretty damn hard to stop.
* The only form of armor worth using in ''SeventhSea'' is a rare form of nigh-magical armor held by one nation. If you're anyone else... well, they don't even print statistics for armor. That should tell you all you need to know.
** Technically, they ''did'' print statistics for armor, if "it does nothing" counts as statistics.
** To quote the ''Player's Guide'', "Everyone else simply does without."
** Armor rules were later printed in the ''[[FanonDiscontinuity Cathay]]'' supplement, which was written after all of the setting's creators had [[JustForPun jumped ship]].
* In ''[[TableTopGame/MiddleEarthRolePlaying MERP]]'' [[note]]and by extension ''{{Rolemaster}}[[/note]], unarmoured was usually better than soft and hard leather armour against most weapons. Each weapon had a strike table against each armour type (AT) and it was far easier to hit higher armors on average, but you dealt mere damage. The real killer in rolemaster/MERP was the critical strike table roll, which was easier to gain against most armors in the game than it was against not wearing armor at all. Soft and Rigid leather was not only easier to hit and deal damage to, it was far more deadly to wear as critical strike table rolls occured more often! Medium armors like chain also suffered from this to an extent against many weapons. Not only did critical strike table rolls deal things such as stuns, even the weakest table (A) had a chance to maim, incapacitate or outright kill your character on a percentage roll! And this is something you not only had to invest dev points in for manouvrability, it also carried a quickness penalty to make you even easier to hit while wearing it!
* Discussed in the ''Fate Core System'', which by default assigns no special bonuses to either weapons ''or'' armor; mechanically, combat is resolved simply using skills, stunts, and aspects just like any other type of conflict. The point is brought up that if one does make some types of weapons and armor better than others strictly in game terms -- and there's explicitly nothing preventing any given GM from doing so --, then player characters will naturally gravitate towards wanting the best, [=NPCs=] (at least the important ones) will have to compensate to not get slaughtered in droves themselves, and it's potentially easy to end up with a game that ends up playing out ''just'' the same way it would if it didn't bother with the modifiers in the first place, only with less variety in terms of "useful" equipment. (Which is, of course, a plausible enough outcome, just not necessarily the most ''entertaining'' one.)
* In early editions, armor was practically pointless in ''Mechwarrior'', the RPG spinoff of ''TabletopGame/BattleTech''. The only armor that existed with any regularity was the flak jacket, armored flak suit, and anti-laser ablative armor. Statistically, any of those armors would stop, on average, three shots from the weapon type they are designed to resist (ballistic weapons and lasers, respectively) and ''nothing'' from everything else. It also only protected a limited portion of the body (the flak suit being the exception--covering more of the body and providing a bit more protection, but degrading more quickly due to it being constantly hit). This meant that your rare and highly expensive laser-absorbing armor could be bashed to pieces by a thug with a tree branch and there was nothing you could do about it, and none of this was much good if your characters were called on to fight vehicles or 'Mechs. Later editions of the game improved this somewhat, but it was only after the advent of the revised second edition that ''Mechwarrior'' characters finally had a modicum of protection to call on.
* In the 4th Edition of ''ArsMagica'' Armour actually makes characters '''more''' vulnerable to injury. This is because the encumbrance penalty imposed by the weight of the armour detracts from the character's Defense, giving the opponent a bonus to their Attack Advantage that can be substantial enough to more than compensate for the armour's Soak.

[[/folder]]

[[folder:Video Games]]
* In ''VideoGame/DarkSoulsII'', the tougher enemies you face don't just have higher attack strength, rather they're are able to 'ignore' your damage resistance (anywhere from 30 to 100 percent). You'd be better off wearing robes or any light armor that is lightweight and/or has special effects (example would be Ironclad Armor or the Chaos Hood).
* In ''VideoGame/TheElderScrollsIIIMorrowind'' and ''VideoGame/TheElderScrollsIVOblivion'' a character's protection depends more on his skill with armor class rather than the armor itself, though despite that [=NPCs=] are almost always armored appropriately. This includes the existence of "Battlemage" profession, military mages wearing heavy armor. [=NPCs=] will occasionally [[LampshadeHanging reference this trope]] if the player asks them for advice. You're warned not to judge how tough a fight will be based on the amount or quality of your opponents armor or weapons, as the really powerful characters don't need these things to kill you.
** Another thing is that, a least in ''Oblivion'', Normal Armour is useless against magic, as are basic shield spells.
** In addition to the above, in ''VideoGame/TheElderScrollsVSkyrim'' armor will never block more than 80% of the damage dealt. If you max out your heavy armor skill tree, it's possible to reach this cap wearing nothing more advanced than steel.
** Skyrim Armor also depends on the level of smithing and which skill tree you invested in. If you are a master smith, alchemist, and trained in the use of light armor, it's very well that a set of simple reinforced leather is actually ''stronger'' for you than even something made from ''dragon bones'', or ebony metal (which is crystallised gods' blood) forged with demon hearts.
* ''VideoGame/{{BioShock 2}}''. Yes, you are wearing a suit that can withstand pressure at the bottom of the ocean. No, that won't help against a gun. Or a wrench. Or fire. Or anything else, for that matter.
** It's weaker than human skin, but it does have two very important features - because the Big Daddy is a bunch of ADAM-infused organs surgically grafted to a diving suit, you get one whole second of undershirt to prevent fatal damage temporarily, at which point you have the option of using a single medkit, which heals ALL damage. This represents the Big Daddy's massive health pool, rather than their damage resistance.
** However, in the first game you do get to equip a Big Daddy diving suit, which, unlike in Bioshock 2, does reduce the damage you take. You still aren't invincible though.
* ''Franchise/MetalGear Online'' lets you customize your player characters, where you have the option of giving him/her combat armor or helmets, but these are merely aesthetic accessories, and have no effect on how much damage you take. You still take as much damage as shirtless male characters or bikini-clad female characters.
* ''SoulCalibur'': The female warrior [[RoyalsWhoActuallyDoSomething Hilde]] and male hero [[TheAtoner Siegfried]] both wear heavy plate armor, and yet they still take damage at the same rate as the rest of the cast, who wear ordinary clothes, fabric bodysuits, or in Voldo's case, a simple codpiece.
** Nightmare too; when he's not Siegfried, he ''[[AnimatedArmor is]]'' a set of heavy plate armor and still takes the same amount of damage as all the bondage-clad nudists running around. Plus, [[GuestFighter Darth Vader's]] in the fourth game and is subject to the same convention too (contradicting the ''Film/StarWars'' example above in "Film").
* Averted in VideoGame/SabresOfInfinity with Banehardened armor, which, while incredibly expensive, renders the wearer extremely effective protection against conventional weapons.
* Played straight in ''VideoGame/DeadOrAlive'', with the fully power-armored SpaceMarine Nicole being just as vulnerable to punches and kicks as the more {{Stripperiffic}}ally-dressed women.
* In ''VideoGame/{{Drakengard}}'', there is no amount of armor you can be wearing, damaged or undamaged, that changes how much damage you take. And in cutscenes, we're shown it works the same way for TheEvilArmy, although that's possibly because the protagonist is a BadassNormal.
* The ''VideoGame/GhostsNGoblins''/''[[VideoGame/GhostsNGoblins Ghouls 'n Ghosts]]'' series has Arthur, who starts in full plate armour: however it just takes [[OneHitPointWonder one hit]] and your armor goes flying off, leaving you to fight beasties in his [[GoofyPrintUnderwear pretty underpants]]. Another hit in that state, and he's dead.
** Ultimate Ghosts 'n Goblins has a variety of armors, most of which can take more than one hit. The trouble happens when you ''need'' a certain armor that can take only one hit to get past a certain point (especially the Angel Armor), meaning that once you lose the armor, you're hosed. Two ways, in fact.
* In the anime-themed PC game ''VideoGame/ShogoMobileArmorDivision'', the enemies come in many varieties, some sporting basic uniforms, others power armor, and still others ten foot tall mini-mechas. The difference that makes in their durability is negligible: 100, 125 and 150 health points. All forms die to a single shotgun blast or a short burst from an assault rifle.
* ''Franchise/FireEmblem'' doesn't actually include armor as a mechanic (except for the 2nd game where shields existed). Defense is based entirely on character growths and class based caps, rather than what armor a character is physically wearing. For example in ''[[VideoGame/FireEmblemTellius Radiant Dawn]]'', full plate wearing Meg's defenses are lower than the breastplate, helmet and shield wearing Aran (although Meg has a higher defense cap, but her growths are so poor she will almost never reach it)
** Still, characters and classes featured with heavy armor tend to have a higher Defense base, growth, and cap.
*** The exception to the above rule is [[CrutchCharacter Jagen]] from [[VideoGame/FireEmblemAkaneia the first game]], who has a 0% defense growth despite wearing his famous purple armor.
* Exists but to a lesser degree in the ''VideoGame/MonsterHunter'' series. While armor is both useful and effective, the trope comes into play in terms of how you'll commonly use them. The good armor is made from killing the monster the armor set comes from many times to get loot used to make it. The problem is that the armor tends to be most resistant to the element said monster uses. Say you kill a monster with electric powers over and over again, you've now made armor most effective in defending against the very monster you now never need to see again. While the armor can still help if there's ANOTHER monster of that element you have trouble with, this still heavily contrasts with crafting weapons which do the opposite (are less effective against the monster you were grinding with and more effective on some other monster).
** When it comes to offering damage protection from monster attacks, most armors in Monster Hunter games are horrible when faced with monsters of the same rank. You got armor with high elemental resistance and high raw defense? Yeah that's great, instead of being killed in 1-2 hits now you can take about 3 (maybe 4!) hits before dying.
*** Being able to take a few more hits makes a huge difference. Try taking on G-rank with a High-rank or Low-rank armor and you will die if a monster so much as sneeze on you. It is very recommended that you upgrade your armor to one of the current rank you're on in order to get the defense even if it means sacrificing armor skill. If both armor are of similar rank though, the defense is negligible.
* While armor ''is'' quite important and tends to provide benefits other than sheer protection in ''WorldOfWarcraft'', these values don't necessarily correlate with the ''amount'' of armor. [[ChainmailBikini Females get away with much less armor in general]], and an Eyepatch provides just as much protection as a full plate helmet, as long as it's given the same armor class. Another weird instance is the druid's bear form, which, despite not showing any armor whatsoever, magically ''quintuples'' the armor rating of his equipment, enabling the usually rather fragile, leather-wearing class to be a very capable tank which outranks full plate warriors and paladins in terms of sheer physical damage reduction (however, they can't use shields to block or weapons to parry, and have a rather limited array of abilities).
** In addition, ArmorIsUseless when fighting elemental enemies whose elemental damage ignores armor, as do spells. Which kinda makes sense to some extent; getting hit by a fireball will probably melt you the same regardless of the thickness of what you're wearing--it may even be worse with metal armor if it's hot enough--but considering how the fire came from a flaming boulder, and therefore part of the damage is blunt force trauma, there's many types of magic for which you must scour your brain for the reasoning of how it damages someone, in that you'll survive a fireball from someone around the same level around you, despite how it's hot enough to ''set a boulder on fire'', which makes it kind of like a meteor...
* In ''VideoGame/{{Fable}}'', different armors have different strengths and weaknesses, but these are negligible. Defeating the final boss wearing nothing but underpants is not only possible, but hardly more difficult than doing so in full plate-mail.
** Lionhead Studios realized that armor was useless in ''Fable'', and as a result, in ''VideoGame/FableII'', you get the same armor bonus for wearing a harlot dress as you do for wearing a heavily layered assassin outfit: ''zero''.
* Played straight in ''GearsOfWar'', where one of the FEW people wearing an honest helmet, Anthony [[MeaningfulName Carmine]], gets sniped in the head early on, killing him. Though the helmet made him one of TheFaceless, despite being an actual character, his death was an in-joke to the developers, based off a study that showed people who wore helmets like that get shot more due to the lack of peripheral vision.
** Lampshaded in ''Gears of War 2'' though. During one level the group is complaining about the smell and even has to run through toxic gas later in the game. The one member wearing a helmet points out that they wouldn't have this problem if they'd wear one. Also, the character with the helmet is the Benjamen Carmine, little brother of Anthony Carmine.
--->'''B. Carmine:''' If you wore a helmet, you wouldn't have to breathe in the dust.\\
'''Dom:''' Yeah, ''[coughs]'' but I wouldn't be able to see snipers so well, would I?"''\\
'''Marcus''' Cool it Dom...
** In ''Gears of War 3'', Clayton Carmine, also wearing a helmet, is walking with the squad towards a COG base when a friendly sniper mistakes them for the Lambent, and shoots Clay in the head [[spoiler:only for the bullet to ricochet off Clay's helmet, prompting a shocked, "Jeez louise, what the ''fuck''?!"]]
** While all the gears tromp around [[WebAnimation/ZeroPunctuation half a car's]] worth of armor, they seem to be about as tough as the Locust, most of whom aren't even wearing shirts. [[DeathWorld Sera]] also seems to have a surprising number of indigenous species that are completely immune to gunfire on some or most of their carapace (including rockworms, serapedes, Berserkers, and [[NamesToRunAwayFromReallyFast Corpsers]]), which begs the questions of why no one's making armor out of them.
** Averted by Maulers and Armored Kantus. Maulers carry a shield that can absorb (or in the case of Elites, ''reflect'') bullets and even rockets. Kantus armor slows the wearer down (and denies it the use of Ink Grenades in Beast Mode) but is nearly immune to bullets. Unlike the Mauler's shield, a Kantus' armor doesn't help it against fire or explosives.
** Exaggerated in ''3'', which has unarmored versions of Anya, Dizzy, Marcus, and a version of Cole in football pads. All can take just as much damage as their heavily armored counterparts.
* ''DynastyWarriors'' and ''SamuraiWarriors'' have a number of characters who run around the battlefield in heavy armour. There is little or no evidence that they take any less damage than the characters who run around in robes or barechested. They do tend to be pretty slow, though.
** DW and SW seem to work off the principle of GlassCannon instead. Those bigger guys or armored guys DO do more damage, or at the very least, have much larger range. Except for Xiahou Yuan. [[BlessedWithSuck Because he just fails that much.]] Whoopee! Free arrows! Now, do you have anything else to offer? Worse, his attacks have a habit of juggling enemies, which means they can't attack, but they also take a third as much damage, making one on one fights take even longer.
* Played straight at higher levels in {{Elona}}, as elemental resistance followed by speed become the most important defense. After all, if an enemy only does 1-3 HP damage, but gets 5-8 TURNS compared to your one, (say a quickling or alien kid, who does additional acid damage on top of that) then you may as well be taking 30HP damage a turn anyway. However, with light enough armor you can cut this down to as low as two or three, and with a pair of rings of speed, even out, as well as get chances to dodge the attacks. However, it is inverted again when you face down [[http://elona.wikia.com/wiki/Fort_of_Chaos_(Beast) Frisia, the cat queen]], as you'll never be able to match her speed unless you play a Catgod as well, or a quickling or bell, so it's best to reduce the damage you take as much as possible and let her kill herself by spamming Firewall/Acidground or throwing things which cause damage over time along with wearing the artifact mentioned. She takes so many turns compared to your character that you'll do much more damage in the same amount of time as trying to hit her with your main weapon, even if she only takes roughly 5-8 HP damage per turn. The other two bonus bosses are chumps compared to Frisia.
* Armor in ''MightAndMagic 6 - 8'' is only as good as three things: Your skill with the armor in question, The abilities of the enemy you're fighting, and how good your Repair Skill is. Given how many late game enemies had abilities that (a) ignore armor class and (b) break armor, you may as well rely entirely on magic resistance once you reach the LostTechnology section of the games.
** Leather armor is ''slightly'' more useful than the other armors - every class that ''can'' use armor can upgrade the leather skill to a level where this is no disadvantage to having one on, which meshes well with that it, as all armors, can carry useful bonuses that have nothing to do with armor class (there are no non-armor options for the torso slot), and in 7 and 8 the Grandmaster bonus applies even if the armor class does not.
* In "VideoGame/SonicTheHedgeHog2006 the first Iblis boss battle with Silver requires you to throw rocks a Iblis's ARMORED HEAD!
* In ''VideoGame/MountAndBlade'', most weapons do cutting damage, which is significantly hampered by armor. Piercing and blunt attacks get through more often, but generally have less power once they pass the armor.
* ''{{X-COM}}: UFO Defense'' is a peculiar case that caused a fair bit of Administrivia/{{Natter}}. A soldier wearing the most powerful armor in the game, hit where it's thickest, has roughly a 2/3 chance of surviving one hit from the most common alien weapon. There's no guarantee against multiple shots. What would be rejected in most games is here a crucial improvement from losing half the squad on nearly every mission. The first armor available occasionally saves from getting their faces imploded, and instead leaves them in dire need of a medic on the field and time in the infirmary when they return.[[note]]Thus doing exactly what reasonable armor can be expected to do in real life; making what would have been fatalities into living casualties.[[/note]] It's another major development.[[note]]The reasoning behind the armor in the game is somewhat complicated and involves random numbers. Basically, when a unit is hit by an attack, the attack can do between 50 and 200 percent of it's base damage. That damage value is then compared to the armor value of the unit (which varies depending on where it is hit), and an additional random value is either added or subtracted to the armor value. If the modified armor value is greater than the modified damage value, the armor holds and ''nothing happens'': no armor reduction, no damage to the unit, nothing. If the armor value is less than the damage value, then the armor is damaged and some of the damage "bleeds" through to the unit. With plasma weapons and rookie soldiers, ANY damage bleed is likely going to kill them, but the damage roulette means that it's entirely possible (though ''extremely'' unlikely) for a human rookie with no armor to survive a Heavy Plasma shot to the chest. Better armor obviously means higher armor values but they don't guarantee survival odds, just improve them.[[/note]]
** Tricky players note that advanced armor makes automatic high-explosive and incendiary rounds into amusing close combat weapons, and that its flying version reduces Chryssalids from nigh-invincible instant death machines to mostly harmless. (While it also makes Silacoids completely harmless, [[GoldfishPoopGang that's not really a downgrade for them]].) The sequel ''Apocalypse'' has much stronger armor.
* ''VideoGame/XCOMEnemyUnknown'', the 2012 reboot of X-Com, plays BodyArmorAsHitpoints, and it ''does'' improve your operatives's survivability in battle as long as you take care to avoid getting exposed to flanking attacks, as {{critical hit}}s will still hurt like crazy. In some cases, the armor can even help your operatives avoid being hospitalized in the medical bay for days or even ''weeks'' if the damage they suffered is less than the bonus health provided by the armor. Furthermore, the advanced suits of armor all possess unique abilities that give your operatives other benefits besides protection from weapons fire.
** The ''Enemy Within'' expansion pack adds MEC troopers wearing PoweredArmor (although they have to literally lose AnArmAndALeg to be able to do that, replacing them with robotic substitutes). MEC troopers are very tough to kill, especially since going into Overwatch without moving during the turn adds more protection. This is to compensate for the fact that MEC troopers are too large to be able to hide behind objects and are thus always exposed.
* ''Franchise/FinalFantasy''
** In the original ''VideoGame/FinalFantasyI'', the Black Belt could wear some equipment, but when unarmored he gains one absorb for each level which will outstrip the absorb he can get from armors at very high levels. It's not something that people who tries to beat the game on a timely pace should worry about, though.
** ''VideoGame/FinalFantasyVII'': The only "armor" you can buy for any character is "bangles," which are essentially large, heavy bracelets. You can see the characters wearing them, and occasionally even making motions as if they are trying to block or deflect attacks with them. As for how well this works... the way the game calculates damage means that defence stats in general aren't really worth the effort to improve (the most effective armor work by halving damage from physical elements), a glitch means that mdef ignores what armor is supposed to contribute to it, and you can cause your defence to roll over if you raised your stats high enough.
** ''VideoGame/FinalFantasyVIII'': While most ''Final Fantasy'' characters equip armor, even if only in inventory, here characters do not wear armor, visually or no. In-universe they're covert operatives who often go undercover, and wearing heavy armor would blow said cover pretty quickly. Besides, with Guardian Forces and junctioned magic, they don't ''need'' it.
** ''VideoGame/FinalFantasyII'' plays this trope straight by the end-game. While armor does exist, Firion will be better off, facing the Emperor with only two Blood Weapons and a Ribbon equipped. Wearing any kind of armor will greatly reduce his chance of avoiding both physical and magical attacks, thus making armor literally useless.
** ''VideoGame/FinalFantasyX'' has this rule too, to a certain extent. Nobody wears armor, aside from the crusaders, who are practically the RedShirtArmy of Spira. Any playable character in the entire game, however, can only equip a weapon and an arm-guard.
** ''VideoGame/FinalFantasyXII'': Subverted in the opening sequence. Some poor sap had a gaping hole in his armor, right in front of his throat. Three guesses where he was shot, and the first two don't count.
* In ''''VideoGame/BlackSigil'': Blade of the Exiled'', armor isn't entirely useless so much as Defense is. You appear to take the same damage from introductory-area enemies, even after abusing a specific shop's buy/sell mechanics to purchase hundreds of Defense Up potions and using them to max every character's Defense. It's for this very reason that it's best to equip armor based on any offense and status resistances they have, as opposed to Defense. At least ''technically'' the armor itself isn't what's useless...
* Played straight in the ''VideoGame/RainbowSix'' games, though this is more of a case of Helmets Are Useless. Heavy armor will completely shrug off shotguns loaded with buckshot at point blank range as well as submachineguns with [=JHPs=] at long range, as long as it doesn't hit your head, which doesn't happen very often since enemies almost always [[BoomHeadshot aim for your head]] and are often equipped with assault rifles. In the first game in particular, the AI was known to score headshots from [[ImprobableAimingSkills beyond the real life effective range of their weapons]] ''[[TheComputerIsACheatingBastard while looking completely the other way]]''.
** Lampshaded in [[Literature/RainbowSix the original novel]], where it is noted that 7.62 rounds will still go through their armour. Of course, it takes about three missions before [[CurbStompBattle anyone they go up against can even get a shot off.]]
* ''VideoGame/OperationBodyCount''. While most attacks will hit armor first, two enemies that start appearing in the first 10 levels will also damage your health directly regardless of armor: Giant rats and [[DemonicSpiders shock drones]]. The former has health damage reduced by the presence of armor, the latter completely bypasses it.
* ''VisualNovel/YoJinBo'': Nobody wears armor, except for [[spoiler: Mon-Mon]], who wears [[BulletproofVest chain mail]] under his clothes. Which does save him from being stabbed in the back in one event, but the trope is played straight aside from that one instance.
* In ''VideoGame/CityOfHeroes'', your powers are completely divorced from your appearance, so armor really ''is'' useless. At least for protection, anyway. If you choose to wear armor, it's typically for conceptual reasons or looking cool.
** Not counting armor (or shields) provided ''by'' your powers, which work and do provide protection when in use. Although there aren't many powers that really produce material armor instead of auras of some sort, and you'll still get something like being temporarily covered in ice or granite instead of plate mail or a flak jacket out of them.
* In the ''VideoGame/SiegeOfAvalon'' Anthology, the action takes place in a castle under siege, which had run out of good quality steel months earlier. Consequently, the armor and weapons coming out of the armory are pretty much worthless--one soldier calls them "tin swords and paper armor," and one of your earlier optional quests is to locate a cache of steel in the ruins of the town outside (though you only get a sword, not armor, for completing it). The real determining factors of whether you survive are how many hit points you have, how quickly you heal, whether you heal yourself using magic (and how good you are at it), and how many hits you actually take. Even the enchanted armor you can pick up toward the end of the game is more useful for the enchantments than the armor they're attached to.
* In ''VideoGame/{{Scribblenauts}}'' it is possible to create armor, helmets, shields, etc. but they don't make it any harder to die.
* None of the possible [=PCs=], or your companions for that matter, wear armor in ''VideoGame/JadeEmpire'', and it doesn't affect their defense at all, although amusingly several incorrect descriptions of you by enemies describe you wearing head-to-toe suits of armor.
* ''VideoGame/NeverwinterNights'' was based on the D&D ruleset, so armor was completely useless for around half of all possible characters at higher levels and only moderately useful for the other half.
** Ditto ''VideoGame/NeverwinterNights2''. At a certain level, you're wearing armor less for protection and more for the bonus effects from the enchantment on it.
* ''SpaceEmpires'': Mostly averted in the series. It can have special effects, like damage regeneration, and armor-piercing weapons aren't very common.
* In ''[[GaiaOnline zOMG]]'' your character's appearance is fully independent of your stats, to allow for total character customization. However, this also means that no matter how cool that Mythrill Armor(sic) looks on you, or how badass you look with your giant axe, you can still get killed by a flamingo if you don't have rings. The opposite is true as well.
** This is illustrated in the zOMG Manga, where a guard named Baldur is equipped with rare and expensive Mythrill Armor and an [[KatanasAreJustBetter Ancient Katana]], but is still taken out in one hit by a Buzz Saw. Conversely, Dani (Who is wearing Armor, but forgoes the chest plate) and Blaze (who isn't wearing armor at all, save for a small leather jacket) are much more effective fighters.
* In ''Franchise/AssassinsCreed'', Assassinations, Hidden Blade {{Counter Attack}}s and ''[[VideoGame/AssassinsCreedBrotherhood Brotherhood]]'''s new Arrow Storm and Execution moves will one-shot anyone regardless of health. Also, the Captain from ''Brotherhood'' multiplayer is a OneHitPointWonder despite wearing full plate. On the other hand, Ezio's damage-taking improves as he gets better armour and more heavily-armoured opponents are themselves harder to kill in a straight fight, with Borgia Captains ([[GetBackHereBoss those that fight you anyway]]) and [[PraetorianGuard Papal Guards]] needing multiple Hidden Gun shots to kill. To add to this, the Armor of Altaïr saved Ezio from a nasty stabbing at the end of ''2'', while part of [[spoiler: the Cesare fight]] is spent stripping off the boss's armour so he can be properly hurt.
** They seem to be improving on that with the enemies, as in ''[[VideoGame/AssassinsCreedRevelations Revelations]]'' the Janissaries cannot be [[OneHitKO one-hit killed]] by the hidden blade.
* ''VideoGame/{{Tyrian}}'': Once your ship loses its shields, its own armor is what separates you from a very explosive death. On higher difficulties, even ships with the highest armor ratings will fall apart after about a dozen hits.
* ''RagnarokOnline'' - upper end armors like full plate armor are comparatively little more powerful than lesser armors. While a character in full plate in most {{RPG}}s can get beat on all day (especially by 'trash' and low level monsters) and not feel it, RO characters in full plate take much more damage than the idea of full plate armor seems to indicate. It is true that armor is upgradeable and you can add 'cards' to the slots, it is ridiculous how little protection the best armors give warriors and tanks.
* ''VideoGame/DeusEx'': straight in the first game. Armored soldiers from UNATCO and Majestic 12 have as many hit points as homeless bums. NSF terrorists are actually weaker.
* DoubleSubverted in ''VideoGame/{{Fallout 3}}''. Normally armor does a pretty good job reducing damage. Then you go to [[DownloadableContent Point Lookout]], where [[ArmorPiercingAttack the enemies automatically get a certain amount of free damage in]]. This means that a player who easily mows through Enclave soldiers and Super Mutants can get pwned by mutated rednecks with shotguns. It can also be double subverted because of the equipment degradation reducing effectiveness over time and the low-quality (as in broken, not poorly made) equipment most [=NPCs=] have, which can result in a pair of Brotherhood of Steel knights in PoweredArmor getting killed by a trio of raiders in Mad Max-style armor.
** ''VideoGame/FalloutNewVegas'' changes the armor calculations from being percentile to being additive, and if you don't exceed somethings armor rating you only do ScratchDamage. It's played straight or averted depending on [[ZigZaggedTrope where you are in the game]]: higher enemy damage makes armor progressively less helpful, and all energy weapons ignore some by default anyway (although one Perk makes metal armor more potent against energy weapons). Any of the various infinity plus one armors, however, do greatly increase your survivability, and the wearables with stat boosts but poor defense are ''highly'' [[CripplingOverspecialization situational]].
*** It does get double subverted on the highest difficulty, and against the most powerful enemies. Basically, they're going to kill you in either 1 or 2 hits, and no armor you wear will help with that. Worse, if they make you slower then lighter equipment. Most of the DLC enemies and some of the main game enemies also scale to the player's Experience level. On the vice versa, your offensive capacity ALSO skyrockets so everyone is basically a Glass Cannon.
*** As with the later-released ''VideoGame/TheElderScrollsVSkyrim'', [[ScratchDamage armor will stop no more than 80% of incoming damage.]]
*** The Giant Rats/Rodents of Unusual Size in Broc Flower Cave, with their saber-like gnawing teeth, especially on higher difficulties, hit hard enough to kill a Courier in two hits at the level where they may first find the cave, regardless of the armor they have procured.
* The improved graphics of ''VideoGame/TheLegendOfZeldaTwilightPrincess'' reveal that Link wears chainmail under his trademark green tunic. But he takes exactly the same amount of damage from goblin attacks with the armor as he does without it in the prologue.
* Averted in the multiplayer online game ''WorldOfTanks'', that is all about armor. Highly armored vehicles take little or no damage when shot by much weaker vehicles. There are weaker spots in hulls or turrets, but that's relative to the overall endurance of the vehicles, and only an appropriately powerful gun can truly exploit them. For example, a Tier IV Russian light tank like the A-20 could empty his ammo rack on a Tier IX Heavy like the IS-4, without causing serious damage.
* Not a very obvious example, but basically everybody in every ''Franchise/{{Halo}}'' game. Energy shields are pretty much the only real defense anybody has (Elites, Spartans, Jackals) in each game, and a unit not having a personal shield, or having its shield ''down,'' is practically synonymous with "defenseless," despite all units (Covenant, Human, whatever) being heavily armored. Not even [[SuperSoldier Spartans,]] with their supposedly incredibly advanced tailored-specifically-for-Spartan painstakingly-manufactured cutting-edge-armor, can survive one single shot to the head ''from a basic pistol'' in ''any game,'' or more than just a couple shots to the body from almost any other weapon in any game. Even though most weapons in the universe are admittedly pretty advanced, it's appalling how useless armor is, when it ''should'' be equally advanced, really.
* ''VideoGame/{{Prototype 2}}'' has a DLC Pack which includes an Armored form for Protagonist James Heller, as well as another that was used by Alex Mercer in the first one; both of them are merely skins, so you won't take any less damage using either one.
** Averted for the [[VideoGame/{{Prototype}} first one]], though; Armor Power does a number on your speed and mobility, but decreases the overall damage you'll take.
* Parodied in ''[[VideoGame/AlexKidd Alex Kidd in High-Tech World]]'', where putting on a suit of samurai armor would completely immobilize you, causing a GameOver.
* Averted in ''VideoGame/DwarfFortress'', up to a point; any stabbing or slashing attack that fails the armour check is re-rolled for bludgeoning damage, which plate armour or chainmail do very little to protect against. Broken ribs are definitely preferable to getting run through with a sword, however.
** One straight example is that the current version's armor is remarkably vulnerable to AnnoyingArrows, with weak-material arrows reliably piercing anything up to adamantine. The only exceptions are that wood or bone arrows/bolts are still liable to deflect off any metal armor while [[{{Unobtanium}} adamantime]] arrows bounce off everything in spite of their hardness because of their extremely low density.
* Averted in ''VideoGame/TeamFortress2'' with the Heavy and Demoman, who wear black ballistic vests and have the highest amount of health of all the classes (300 and 175 HP respectively) (aside from the Soldier, who has 200).
* Averted in the third ''VideoGame/MaxPayne'', where armoured paramilitaries and [[spoiler: {{Dirty Cop}}s]] are noticeably harder to kill than unprotected favela gangbangers or mobsters. The extreme of this are the thankfully rare {{Heavily Armored Mook}}s that are ImmuneToBullets centre mass and can only be killed with headshots. It's especially obvious when Max goes to the [[spoiler: UFE HQ]] and fights both the armoured frontliners and the unarmoured desk jockeys; the latter are much easier to kill.
* At first it was {{Subverted}} in ''VideoGame/StarWarsTheOldRepublic''. Tanking classes, the ones who could take the most damage, typically wore heavy armor that would cover them head to toe, even the Jedi ([[HelmetsAreHardlyHeroic though rarely with face-concealing gear]]). The SquishyWizard classes were restricted to light armor, and the rest were an intermediate between the two.\\
\\
Then with later game updates, adaptive armor was added, which are really just ImpossiblyCoolClothes. Since armor rating is based off the mods added to them, and adaptive armor sets could accept any mods, this allows players to disassemble hyper-advanced PowerArmor, put the components in a flashy robe or jacket, and get the exact same ratings. Now, the servers are filled with Jedi running around in [[Film/ReturnOfTheJedi Leia's stripper outfit]] and Troopers relying only on their well-toned abs for chest protection, with equal chances of winning against better-armed (and outfitted) opponents.
* ''VideoGame/StarTrekOnline'' has this problem due to the fact that the game really relies on DPS - even if you have a high resistance rating and powerful shields, escorts can melt that and your hull in an instant.
* We don't know enough about ''VideoGame/PillarsOfEternity's'' game mechanics yet to say one way or the other whether this is true in general, but the lore does speak of an unusual subversion. The [[FantasyGunControl primitive black powder muskets]] of the setting are effective at piercing wizards' spell shields at close range, so wizards have turned to bulletproof plating as a defense against gunslingers.
* Played straight (at least after you become a Jedi) in ''VideoGame/KnightsOfTheOldRepublic'', where the main character wearing armor actually [[ArmorAndMagicDontMix makes Force powers unusable]], making it necessary to downgrade from heavy combat vests to the simple robes of a Jedi. The sequel introduces a few types of armor designed for Force-users that lack this restriction, although they're only available as random loot.
* Played realistically straight in ''7.62 High Caliber''. Combat is extremely lethal and even the weakest pistol in the game can cause fatal damage with two or three shots to the chest. Armor, like in real life, only provides a token amount of damage resistance, enough for several assault rifle rounds at the most; ceramic and titanium plates can be inserted for improved protection in certain vests, but they can be broken completely by enough damage and have to be replaced. Even worse, helmets and bulletproof vests only protect the head and torso respectively, so any shots not to those areas get no damage resistance (unless you turn on an option on the difficulty settings). And armor piercing ammo (or powerful cartridges) tend to just slice through that armor anyway, so it'll usually only provide just enough protection to escape immediate death and run for cover. As in real life, the best defense is to not get shot.
* ''VideoGame/KingdomHearts''
** The only reason why Sora wears armor in [[Film/{{Tron}} Space Paranoids]] is [[FisherKingdom to blend in]]. Of course, the armor happens to be his magical clothes in a different shape, and he can still use his Drive Forms; his circuits change color to match each form, from [[OneManArmy red]] to [[ArmorAndMagicDontMix blue]] to [[HarsherInHindsight yellow]].
** Completely played straight with his and Riku's armor for [[Film/TronLegacy The Grid]]. Their armor's only purpose here is to hold their Identity Discs and, [[spoiler:in Sora's case, his Recusant's Sigil; in Riku's case, his Spirit Dream Eater symbol]].
* In ''VideoGame/StarCraftI'' each point of armor translates to one point less damage taken from each attack. Given how little armor units have and the rate most units attack or do damage, this really doesn't make an appreciable difference.
** Not entirely invoked because while armor typically does very little to reduce the damage of a Siege Tank which typically does a whopping 70 damage it matters little if you reduce the damage by a few points. But take a Terran Marine which typically does 6 points of damage and send him up against a fully upgraded Battlecruiser which will have 6 points of armor and the marine will do little to no damage.
** Also, the "armor" stat isn't the full effect of armor. An unarmored human civilian has far fewer hitpoints than a generic marine.
* In the ''SyphonFilter'' series starting with the second game, certain enemies deliver headshots that OneHitKill regardless of armor condition. Explosions fire, and certain high-power guns also ignore armor. In the fourth game, there are thugs that wear both flak jackets and helmets, but still die from a single headshot.
* In the ''Videogame/TotalWar'' series, whether armored troops are useful depends on both how you use them and what they're up against. Heavy knights on foot or on horseback can tear into light infantry with minimal losses and wade through heavy arrow barrages with limited casualties, but horse-mounted knights are still very vulnerable to pikemen and spears even with all their armor and barding. Dismounted heavily-armored troops are also vulnerable to cavalry charges unless they have their own spears, since all that armor won't help when a lance-wielding knight in full plate charges you on the back of a furious destrier. Heavy armor can also be a drawback when fighting certain heavy infantry types like Venetian Hammers, who deal massive bonus damage to heavily-armored units.
* Partly true in ''GalacticCivilizations II'', given that armor is one of the three types of defenses you can install on ships, the other two being DeflectorShields and [[PointDefenseless anti-missile systems]]. Basically, each type of defense is a good counter only for a specific type of weapon. Armor is good against kinetic projectiles, shields are good against energy weapons, and anti-missile systems are (obviously) good against missiles. Against any other type of weapon, their effect is reduced to the square root of the value. So, armor with a defense rating of 9 will only provide 3 defense points against lasers or missiles. Even without this approach, late-game weapons completely outstrip equivalent defensive technologies to the point of making them pointless even if they match.
* Averted in ''VideoGame/{{Warframe}}''. Grineer heavy armour means that even basic Lancers and Troopers are IncrediblyDurableEnemies that can take a few bursts of fire if you don't AttackItsWeakPoint, and their EliteMooks are even tougher. In contrast, Corpus only wear future spacesuits and have to rely on their DeflectorShields, turning into GlassCannon once those are down.
* ''VideoGame/{{Boktai}}2'' had armor available to the main character which ''does'' offer a miniscule defense increase, but also decreases his ''movement speed'' based on it's weight. Players very quickly learn they're better off playing as an armor-less FragileSpeedster that is quick enough to dodge and outrun enemies and with a curative item or two on standby, rather than a slow-as-molasses character that's still a GlassCannon.
* ''Franchise/MassEffect'' both averts and plays this straight:
** The first game included armor customization for both Shepard and his/her squadmates, with armor bonuses and protection factored in through multiple armor classes.
** The sequel both played this straight and averted it. The player could now acquire armor pieces that improved various aspects of their health, shields, shield recharge time, ammo capacity and so forth. Meanwhile, all of the squadmates' armors became merely cosmetic, with instances like Garrus' damaged armor, Miranda's catsuit and Jack's "strips of clothing" having the exact same armor rating as their fully-armored versions from the Alternate Appearance Pack DLC's.
*** The two healthiest teammates are Grunt, a Krogan in full armor, and Thane, who wears a [[BadassLongcoat trenchcoat]] and bares the skin over his vital organs for medical reasons. However, this doesn't extend to the Suicide Mission, where characters who are heavily armored can fall just as easily as the one's who aren't during the rendezvous with the secondary fire team.
** In the third game, squadmates received a 25% bonus to certain stats (shields, power damage, weapon damage, etc.) based on what costume they are wearing. However, the game also played it straight in certain situations (having [[spoiler:Ashley/Kaidan potentially die from a single shot to their torso during the Cerberus Coup]]) and averted in others (Shepard's armor saving his/her life, but being burned off, when s/he's hit with Harbinger's beam).
*** Likewise, Tali is notably covered with what appears to be blood in the Extended Cut's evacuation scene, even if she's wearing her From Ashes DLC costume (which includes an armored facemask).
* In the first ''{{Diablo}}'', armor was virtually mandatory for players but due to a bug, monsters with high armor rating were actually easier to hit. Diablo himself had a 95% chance to be hit by even a level 1 character swinging a broken dagger.
* In early versions of ''{{Diablo}} II'', enemy attack rating was actually four times bigger than displayed, making the "chance to hit" percentage meaningless. As a result, and because most advanced armor types didn't have unique versions and required more strength (which was a dump stat unless you were a barbarian) there was little point in going higher than the most basic armors. As well, defensive skills that increased armor were useless. The attack rating change was made at the last moment before release because the game was considered to be too easy.
** The expansion reduced the multiplier from x4 to x2 and added unique versions of better armors. It still wasn't enough because for some reason you had a 95% chance to hit while moving and you're always moving. Using a shield was infinitely better.

* In ''Webcomic/ErrantStory'', weapons technology (guns, magic, Durus Flamma weaponry, etc.) has advanced significantly farther and faster than armor, making most armor relatively useless. Sarine [[{{Lampshade}} comments]] on this when considering if she should get her damaged armor repaired, stating that most people don't even bother wearing armor any more because of it. However Jon did have to fire pointblank in an armor-wearing elf's gut just in case.
* In ''Webcomic/ExterminatusNow'', the main characters don't bother to wear armor when assaulting a facility infested with demons. Since the only real defense against a demon is to not get hit at all, armor would only slow them down.

* In ''OrionsArm'' early space warfare is described as being like playing hide-and-seek with bazookas.
* {{Tobuscus}} parodies this in his [[WithLyrics Literal Trailer]] for ''VideoGame/AssassinsCreedBrotherhood''. The lyrics accompany Ezio defeating two pairs of guards with his Hidden Blades and throwing knives, respectively.
-->''Hopefully those guards have good armor / No they don't, maybe they do / They don't.''
* Averted in ''Literature/{{Worm}}''. Taylor's spidersilk costume is bulletproof and knifeproof and has saved her life many times over.

* In ''WesternAnimation/{{Futurama}}'', Bender's Big Score, the head nudist scammer informs the cast that he was wearing a doom proof vest -- then dolefully repents that he wasn't wearing doom-proof pants.
* ''WesternAnimation/DuckDodgersInTheTwentyFourthAndAHalfCentury'': Duck Dodgers plays this trope straight in his first confrontation with Marvin the Martian. Marvin threatens him with disintegration-ray. He smugly announces in an AsideComment that he is wearing a disintegration-proof vest, and [[ExactlyWhatItSaysOnTheTin indeed he is]]; Dodgers dares him to shoot, and Marvin does so. Dodgers disintegrates. The completely undamaged vest hangs in mid-air for a moment before plopping onto the pile of Dodger's ashes.
* At the end of the ''UltimateAvengers'' movie, when the team fights [[ComicBook/IncredibleHulk The Hulk]], guess who appears to be doing the least well in the fight? ComicBook/IronMan. That's right, the only dude wearing any kind of outfit that would seem useful when fighting something that can rip a tank apart, is the one who seemingly does the least. This becomes somewhat ridiculous when you realize that CaptainAmerica (who has enhanced strength and speed but is otherwise entirely human) [[MadeOfIron receives direct hits multiple times and is still conscious at the end of the fight]]. Clearly, Cap knows how to roll with a punch.
* In ''WesternAnimation/StarWarsTheCloneWars'', the Jedi wade into battle wearing ordinary fabric (and sometimes quite [[MsFanservice revealing, in the cases of Aayla and Ahsoka]]) clothing, while the Mooks under their command have full body armor and armor. The latter get mown down by the dozen; the former only get killed for [[RuleofDrama drama's]] sake. Though Obi Wan wears some of the clone trooper armor that he's first seen wearing in [[WesternAnimation/StarWarsCloneWars the previous Clone Wars cartoon]].
** One episode sees [[RoyalsWhoActuallyDoSomething Padme and Satine investigating]] a poisoning outbreak. When they finally track down the badguys, said badguys open fire. The front line consists of consists of one lightly armored officer and two ''heavily'' armored guards bearing blaster-deflecting shields. Guess who goes down?

[[folder:Real Life]]
* Varies in terms of ballistic armor; in the United States, most bullet-resistant vests are rated based on the [[http://en.wikipedia.org/wiki/Ballistic_vest#Performance_standards NIJ's laboratory testing]]. Each tier is rated based on the highest-powered round it can stop. If you find yourself wearing a type IIA vest in a firefight, for example, it should do its job fairly well if everyone present has a 9mm handgun. But once somebody breaks out a .44 Magnum, you might as well be wearing so many kitchen aprons.
* During some battles, Greek hoplites did not have torso armor and relied on their huge shield - hoplon - for protection. Note: They did have normal clothes, and likely also had skirts which served as a part of armor.
* A CyclicTrope in regards to naval warfare. During the age of WoodenShipsAndIronMen, cannon fire could blast through anything that could float, so warships didn't bother with armor. Then came the era of ironclads, where cannon balls would [[NoSell bounce off]] armored hulls. This began an arms race between naval weapons and naval armor that saw both getting [[SerialEscalation ever bigger and heavier]]. This pattern finally broke in UsefulNotes/WorldWarII, when it became clear that heavily armored warships were not effective against serious airpower. Thus, ships were generally low on armor again... at least until the 1970s and 80s, and especially TheFalklandsWar showed that then-modern destroyers were so unprotected that they would take catastrophic damage from things that WWII-era ships could just shrug off. So they began adding ''some'' protective armor back; for instance, the ''USS Cole'' (a 90s design) survived an explosion that would've destroyed a 70s-era Spruance-class destroyer.
** Armor for wooden ships was common, just not ''metal'' armor. The 24 inches of oak timber that make up the outer skin of the USS Constitution were *very* effective in repelling solid shot from contemporary opponents, so much so that it's nickname was "Old Ironsides". Similar construction on most period ships meant that long-range cannon fire was mostly useless for sinking a ship - the English expended a full fleet's worth of ammunition to little effect on the Spanish Armada in the first day's battle, simply because they wouldn't close to a range where their cannon shot could penetrate the wooden sides of the Spanish galleons. Only at close range (under 50 yards) could cannon of the era be counted on to reliably penetrate the sides of warships.
** The Soviet Navy feared the Iowa-class battleships above any other ships in the US fleet because of this. There is a story that they even nicknamed them the "Cockroach Battleships" because, when the Sovs ran simulations, they just wouldn't die.
** In practice, UsefulNotes/WorldWarII capital ships could survive tremendous amounts of air attack, enough that ''Tirpitz'' needed a gigantic 5.4 ton supersonic bomb designed specifically to sink her, [[CrowningMomentOfAwesome and it survived the first hit from it well enough to steam under her own power afterwards]].
*** And the atomic bomb ''itself'' is [[AwesomeButImpractical somewhat unusable]] weapon...
*** The problem with battleship armor was that (since just armoring the whole ship equally would have made it unreasonably heavy) it was optimized to protect against incoming shells, and there primarily those coming in on relatively low angles and hitting the sides. High-angle shots and bombs would hit the thinner deck armor, and torpedoes would just hit below the armored belt in the first place (indeed, the original purpose of destroyers, all the way back to before World War ''One'' was to serve specifically as ''torpedo boat'' destroyers to help protect the vulnerable battleships against just such attacks). These weaknesses were never truly eliminated, and since gunfire is at best a secondary threat on the modern naval battlefield to begin with the main defensive benefit of a hypothetical 'modern' battleship would be its sheer ''size'' -- which doesn't really justify the expense, especially given that aircraft carriers are vastly superior. Battleships simply have no purpose anymore.
** A similar effect ended up going into the use of anti-torpedo technology. At their advent, ships used Torpedo nets to "catch" torpedoes and explode them further from the hull to reduce damage. This stopped working after WWI when Torpedoes became fast enough to penetrate Torpedo nets. So designers came up with the anti-torpedo bulge, an additional section of the hull with absolutely no purpose other then to be destroyed by torpedoes in lieu of a hull breach. Eventually, torpedoes became guided, being able to explode under the ship. Now a days there is literally no defense against torpedo attacks from modern submarines.
*** Not entirely true. The VA-111 Shkval supercavitating torpedo was designed as an anti-torpedo weapon. However, there are some operational problems, given that the oxidiser for the rocket motor consists of over a ton of [[http://en.wikipedia.org/wiki/Russian_submarine_Kursk_explosion concentrated hydrogen peroxide]]... not to mention the fact that anything going that fast underwater cannot be guided with any form of precision.
* Modern body armor is all about tradeoffs.
** The lightest vests are very light, but only block handgun bullets, and then only over a limited portion of the body. Many provide no protection at all against knives and similar sharp objects, which is a problem for prison guards, necessitating the development of armor which was both knife and bullet resistant.
** Heavier vests, such as dragon scale and interceptor body armor, can provide protection even from rifle rounds thanks to ceramic plating, but only the portions with plates are protected, often leaving limbs vulnerable. Dragon scale armor is more flexible, but less heat-resistant, as the glue can fatigue in extreme heat.
** Heavier armor still is available, but it is considered too heavy to be worn for everyday use - it is typically only worn for extreme situations, such as bomb defusal and similar things. It can provide great resistance, even to the limbs, but the weight is prohibitive.
* During UsefulNotes/WorldWarI, armies experimented with chain mail and found that it actually made bullet wounds ''worse'' -- it couldn't stop a bullet ''and'' the rings would shatter, shoving more shrapnel into the wound than if the bullet just hit an unarmoured person. However, when hung like a curtain, it proved surprisingly effective at stopping shrapnel, leading to terrifying items like the British [[http://upload.wikimedia.org/wikipedia/commons/3/3b/Splatter_Mask_%28WWI%29.jpg splatter mask]] for tank crews.
* Not the fault of the armor, but human psychology can make armor useless. People tend to react to increased safety by ''taking more risk'', in an unconscious attempt to balance risk versus reward (riskier behavior is offset by safety equipment like armor, resulting in increased reward for the same amount of risk); this is called the [[http://en.wikipedia.org/wiki/Peltzman_effect Peltzman effect]]. The problem is that a) risky behavior may transfer the risk to {{Innocent Bystander}}s rather than the one wearing the safety equipment, and b) people are ''really bad'' at judging risk, meaning that instead of balancing out, safety equipment + risky behavior may actually be significantly ''more'' dangerous than no safety equipment + no risky behavior.
** The battlefield behavior of medieval [[KnightInShiningArmor knights]] sometimes appeared to confirm this. Knightly armor, especially full plate armor which developed in the 14th century, was actually quite effective and useful. Not only did it offer more protection against arrows, swords, and lances than anything else available, but it was much more [[RealityIsUnrealistic light and flexible]] than most modern people realize. The problem was that bodies of knights were often so eager to come to grips with the enemy--both for glory and to capture loot and ransoms--that they would sometimes decide to charge against a highly prepared, dug-in enemy line [[LeeroyJenkins without waiting for]] their own crossbowmen and infantry to soften up the enemy enough for a cavalry charge to have a chance of breaking through. In the worst case such recklessness could lead to a bloody defeat, and the slaughter of mounted knights at Courtrai in 1302 and Crecy in 1346 may have been partly due to the French cavalry's overconfidence in possessing better armor than their opponents.
*** Averted by Julian the Apostate. He thought he was a living god, attacked a Persian cataphract unit whilst wearing no armour, and [[SuicidalOverconfidence ended up with predictable results]].
** This was brought up on QI - The safest place to fix a large, sharp spike into a car was right in the middle of the steering wheel. Drivers are so used to a cocoon of airbags and crumple zones that they take more risks when driving, often to the detriment of those around them. This isn't so much ArmorIsUseless for the driver so much as the driver's armour for any unfortunate sod in the way.
** Though not technically for "combat" but still a form of battle, protective gear in full-contact sports has spurred similar discussions. In games like American Football or Hockey, the response to improvements in padding and helmets was to simply ''hit harder.'' Concussions and neurospinal injuries now plague both sports to a startling degree in comparison to their early years.
* Additional protection also introduced additional risks in boxing. In the bare-knuckle days a blow to your opponent's head would damage your hands too much to be viable, but now boxing gloves protect the hands these blows have become a lot more popular, meaning both fighters are at risk of more serious injuries.
* Bomb-disposal technicians have to weigh the odds that protective armor suits will actually shield them from injury against the degree to which it may impede their vision and movement. If an explosive device is deemed sufficiently powerful that armor can't possibly help, and robots aren't an option, a brave technician may forego armor to free up their hands to work (and allow them to run like hell if the attempt to deactivate it proves futile).
