Shields. Big pieces of wood and/or metal that protect at least one half of your body against attack. Pretty useful in battle, you might think. And indeed some characters will gratefully sigh that LuckilyMyShieldWillProtectMe. Others, however, are not so sure.

In reality, people covered by a shield from shoulder to knee are rather difficult to hit. Only their head and calves/feet are exposed. This meant that in {{the Middle Ages}}, a popular trick was to stab your opponent in the foot and then, whether they saw what you were trying to do and went to protect their foot, or didn't and dropped their guard when hit, you stab them in the face. Which is arguably less [[RuleOfCool cool]] than [[SliceAndDiceSwordsmanship heroic slashing]].

ShieldsAreUseless applies whenever shields are shown to have a negligible effect in combat. A [[TheHero Hero]] may discard his shield before charging the BigBad just to show how BadAss he really is. Yes, our hero is so awesome that he doesn't need a shield. In the villainous version, {{mooks}} will have shields - but the good guy, armed with the {{BFS}} or DualWielding, will still slaughter them by the hundreds. Apparently they learn to use their shields at the medieval equivalent of the ImperialStormtrooperMarksmanshipAcademy.

Closely related to ArmorIsUseless. Not to be confused with DeflectorShields.

Contrast LuckilyMyShieldWillProtectMe, BarrierWarrior. Compare and contrast ThrowingYourShieldAlwaysWorks -- it shows there's something you can do with them, but rather relies on the belief that there's no particular use in holding onto it.

[[folder:Anime]]
* Samson is one of the few characters in ''Manga/{{Berserk}}'' to use a shield, and as soon as he blocks with it instead of parrying with his weapon a single slash from [[{{BFS}} Guts' swords]] went through it, [[ArmorIsUseless Samson's helmet]], and his entire head.

[[folder:Comic Books]]
* In ''ComicBook/{{Asterix}}'', the Roman legionariess are regularly shown with their large ''scutum'' wall-pattern shields, often put into strong defensive formations like the Tortoise or the Square. Historically, such shields and formations were quite effective. Unfortunately for the Romans, their defenses are worth precisely jack-squat against the Gauls of the UndefeatableLittleVillage, who [[FoeTossingCharge plow through formations and flatten legionaries]] on a regular basis, which usually ends with both legionaries and shields crumpled like newspaper. Usually, ''scutum'' only see some use when the Gauls get their hands on them...to [[ShieldBash bash legionaries over the head repeatedly]].

[[folder:Film]]
* In ''Kingdom of Heaven'', when [[spoiler:the walls of Jerusalem are breached]], Orlando Bloom's character throws aside his shield and charges into the fray with only his sword. In reality this would be a death sentence.
* In the ''Film/TheLordOfTheRings'' trilogy, shields are used for a variety of standard and creative purposes, but often we see the {{Red Shirt Arm|y}}ies on both sides just letting their shields hang by their sides as they're casually dispatched.
** The only member of the Fellowship to carry a shield is Boromir, and we know what happened to him.
** The most famous use of a shield in the trilogy? A surfboard for Legolas.
* In ''Film/{{Hero}}'', Flying Snow and Broken Sword fight through the entire imperial guard single-handedly, slicing through their shields like cardboard.

[[folder:Live-Action TV]]
* In ''Series/GameOfThrones'', Bronn refuses a shield for his duel with Vardis Egan. Combined with his lighter armor, he's able to use his increased mobility to defeat the MightyGlacier.
** Brienne of Tarth's shield isn't of much help in the melee, as Ser Loras Tyrell causes enough damage to it with his axe that she is forced to discard it during their fight.
* Because of how shields were treated by the simulation model at the time the episode aired, the Viking's shield is this on ''Series/DeadliestWarrior''. Specifically, all equipment was ranked by the number of kills made, and the shield (obviously) recorded the fewest kills of all the equipment assigned to the Viking and Samurai (if you're curious, the Samurai was given a ''kanabo''[[note]]gigantic wooden club studded with metal that's most commonly attested as a mythological weapon wielded by ''Oni''[[/note]] in the same slot as the Viking's shield). The simulation did not give ''any'' consideration to how many deaths the shield prevented (its primary function).

[[folder:Tabletop Games]]
* Shields in ''TabletopGame/{{GURPS}}'' provide no help against guns and energy weapon unless they're big enough to hide behind.
* ''TabletopGame/DungeonsAndDragons'': Shields give a passive bonus to your AC, typically by a mere 1 or 2 (5% or 10%) without any modifiers. In doing do, however, they take up a hand, preventing your character from using both hands for offense. Various magical enchantments, feats, and different rule systems can be used to make shields more useful. These examples should be listed in LuckilyMyShieldWillProtectMe.
** ''Basic D&D'' shields only provides a nominal passive bonus to AC. However, they provide BreakableWeapons known as Shield Weapons that give an attack and a better AC bonus if you train them well enough.
** In the 4th edition of ''Dungeons & Dragons'', shields provide no armor bonus if the character has no proficiency.
* ''TabletopGame/D20Modern'' allows the player to carry a shield. While it may seem like an odd choice in a game where firearms are generally quite available, sufficiently large shields (like riot shields) which also provide ballistic protection offer the benefit of ''cover'', a vital mechanic for staying alive.

[[folder:Video Games]]
* Sniper Joes are shield-toting enemies you'll find in many of the classic ''VideoGame/MegaManClassic'' games. Their shields are quite effective at blocking even fully charged buster shots, but are useless against weapons that go ''through'' enemies, like the Elec Beam. Similarly, [[SpellMyNameWithAnS Mettool/Metall/Mettaur]] hide under hard hats, and there are weapons that can destroy them while they're hiding.
** VideoGame/{{Mega Man X}}2 featured shielded enemies who could be temporarily disarmed with a single charged shot.
** As of ''VideoGame/{{Mega Man X}}8'', X's fully charged buster shot, Zero's 3-hit sword combo, and Axl's rapid-fire shots can flip Metools over. They all also have at least one boss weapon that breaks shields like the previously-mentioned techniques, and one that bypasses shields completely.
* The businessman's briefcase shield, however, is no match for the mighty MadKarateMan's skills!
* ''VideoGame/WorldOfWarcraft'': Played straight for offensively-minded Warriors, Paladins and Enhancement Shaman, which will much rather use a two-handed weapon or dual-wield. Averted for tanking, where the shield provides a good chunk of armor, allows blocking and is required for several useful abilities such as Shield Bash (smacking an enemy with the shield to interrupt spells).
** Nowadays however, the tank specializations for warriors and paladins can be quite deadly in PvP if used right through combination of being able to survive normally lethal burst and being concentrated on while being able to deal decent enough damage to be a threat as well as taking up time from people who try to kill them while their allies enjoy not being attacked. A well geared warrior/paladin designed like this can tear lesser geared damage specialized classes apart, especially cloth wearers. One on one fights with them can be quite unfair due to their survivability as well.
** The Death Knight class is the only plate wearing class that cannot use shields. They can still act as a tank but use other damage mitigation abilities to offset the lack of a shield.
** Paladins and Shaman also find some shields to be useful for spellcasting while still offering decent protection (blocking won't be very effective, but shields still make up about a third of the players total armor value).
* In ''VideoGame/TalesOfSymphonia'', Kratos and Zelos can equip shields. They don't actually do anything except add a few points to the defense stat.
** Actually, the shields can occasionally deflect insignificant projectile attacks that happen to land directly on their hitbox. ''VideoGame/TalesOfPhantasia'' (the first game in the series) had Cless, whose shield showed up on his sprite even when he didn't have one equipped, and could sometimes negate enemy attacks if he wasn't moving.
* ''VideoGame/{{Age of Empires|I}}'': Several units carry shields (in some cases added by upgrades) without getting any tangible benefit from them.
** ''Age of Empires Online'' averts this since shields are part of all units equipment that are seen using them. Generally speaking, they add a slight health boost and a significant ranged defense boost. the Babylonian Shield Carrier is entirely based on this, using a massive shield to make ranged attacks almost useless.
* Bastiodon from ''Franchise/{{Pokemon}}'' has a shield as a face and is one of the most defensive Pokémon in the game, but that doesn't stop Ground and Fighting-type attacks from walking all over him.
* Played nearly (and painfully) straight in the Punchout-esque WiiWare game ''Rage of the Gladiators''. While some attacks can be blocked with the shield, most simply go right through it and [[NintendoHard deal full damage to you.]] Some of them can't be evaded and need to be blocked with a shield though, like most long-lasting beam attacks.
* ''VideoGame/EarthwormJim'' will encounter Lawyers who hide behind their bulletproof briefcases. Luckily Jim can whip them out of their hands easily.
* The Tsaesci, a race of SnakePeople in ''Franchise/TheElderScrolls'' universe, have a cultural disdain for shields, since their martial arts emphasize agility over blocking. If a Tsaesci warrior doesn't want to get hit by his opponent, ''he gets out of the way''.
* ''VideoGame/MetalSlug'', a shielded infantry can take many hits from gun shots, but with grenade, the shield goes down in one hit if the bomb doesn't outright kill him.
* Throughout the core ''VideoGame/PhantasyStar'' series (outside of the first game), you are given the option of equipping shields on men and "emels" on women for extra defense. However, the games, instead of having dedicated weapon and armor slots, equip the characters' left and right hands. When it is nearly always more effect to either [[DualWielding dual wield]] or use a two-handed weapon, you're going to ignore shields pretty fast, unless you stick them on your mages.
* Thoroughly averted in ''DwarfFortress'', which handles shields unusually realistically; instead of counting as extra armour, they grant a large bonus to a separate 'parry' role and also act as a secondary weapon that does quite respectable bludgeoning damage. If anything, they're actually overpowered at the moment because BreakableWeapons and other equipment haven't been implemented, so even a simple wooden shield can deflect a blast of dragonfire and suffer no damage.
* ''VideoGame/TeamFortress2'': Played fairly straight with the Razorback, a shield for the Sniper whose only purpose is to prevent the inevitable BackStab but has only one use that delays the Spy for literally two seconds, is clearly visible to the enemy (so the Spy can just shoot them with their Revolver), and the Sniper might not even notice it breaking (and when he does, he only has his melee weapon for self-defense at close range).
** The available unlocks released after the initial class updates subvert this. The Darwin's Danger Shield provides the Sniper with an additional 25 hit points and a 15% reduction in bullet damage. This combination of bonuses allows them to survive uncharged headshots or fully charged bodyshots (even offsetting the machina damage bonus) when at full health, while simply being more vulnerable to explosive damage. Considering that a sniper's greatest threats are other snipers, and not explosive classes... there's a reason that this weapon has been consistently banned in every competitive or even semi-competitive league.
* In the original ''VideoGame/SuperSmashBros'', Link's shield is purely cosmetic. Later games decided to fix this by allowing his shield to block attacks while he's standing still.

[[folder:Real Life]]
* Mostly averted. The lighter your armour is, the more the shield counts for defence. Oftentimes it was the warrior's only defence.
* Inversely, the heavier your armour is, the less the shield counts for defence. With the invention of full suits of plate armour, knights stopped carrying shields because they were already so heavily protected that a shield was little more than an extra encumbrance. Compare the [[http://en.wikipedia.org/wiki/Kite_shield kite shield]] of the early Middle Ages to the considerably smaller [[http://en.wikipedia.org/wiki/Heater_shield heater shield]].
* Use of shields also depends on culture. Japan, for example, effectively abandoned the use of personal shields from the late Heian period onwards, while nearby countries like China or Korea still used shields often.
