"What scared me the most was when my father would put on the gasmask. His face would disappear... This was not a human being at all."
An extremely popular form of the Faceless Goons
, achieved by taking your enemy Mooks and giving them all gas masks. Note that this almost always occurs in situations where the gas masks serve no real practical purpose
, as chemical weapons aren't even a factor in whatever conflict is involved.
In situations (especially video games) where the majority of Mooks are not Faceless Goons
, gas masks are often the mark of Elite Mooks
. Despite the prevalence of gas masks amongst the enemy forces, it never seems to occur to them to use chemical weapons against the heroes. This is even though 1) being evil, they presumably have no qualms against doing so and
2) the heroes typically are wearing nothing except civilian clothes and a smile. If they're lucky
Funnily enough, in many video games, enemies wearing gas masks are still affected by gas-based weapons.
Let us be brutally honest, though — it looks either damned cool
or damned scary
. There's a reason Vader's
face looks like a stylized gas mask. May also show up as the Mask part of Coat, Hat, Mask
, and more commonly as part of a Malevolent Masked Man
ensemble. See also Hazmat Suit
The lack of an obvious need for gas masks may be justified as preventative measures: in other words, if everybody has a gas mask, no enemy will waste time attempting to gas them. British citizens were issued gas masks during World War II
for this reason, and Germany never dropped chemical weapons on England (so they either weren't needed or worked perfectly - take your pick.)

Anime & Manga
- Bubblegum Crisis:
- A rare good guy example is the S.W.A.T.-like troopers of the Armored Division Police who wear gas masks when going into combat, even though they mostly fight cybernetic killer machines which never actually use gas as a weapon. It's possible that they only wear those masks in order to prevent the viewer from becoming too attached to the Red Shirts.
- There is a certain scene in the first movie hinting why they wear them every time. A short view from the perspective of one trooper shows them having H.U.D.s in the goggles. So they might be a cheap way of ensuring gas protection, combat information, and radio communication.
- Also note that they are normally not meant to fight military-grade boomers; Dialy in the first episode even suggests letting the military handle the boomers. The ADP is normally meant to fight terrorists or criminals using high tech or civilian type boomers which went rogue. In the former case, gas attacks might happen and smoke grenades might be used by the police itself. Also, since they have riot shields in their arsenal, they might also be used as riot control, in which tear gas might be used by the police.
- Zaku IIs in Mobile Suit Gundam have cables running around their faces into a "snout", giving them a gas-mask-like look. Combined with their Mono-eyes and the fact that they're (Humongous) Mecha-Mooks, it makes them nearly the ultimate in mook-dom. This reaches its peak with the Geara Zulu from Mobile Suit Gundam Unicorn, which actually does look like it's wearing a gas mask.
- Used weirdly during the chuunin exam: Team 7 + Kabuto run into some ninjas from another village, but there are only three of them; they're wearing cloth masks separate from their gas masks which only cover their mouths, and they can be easily told apart.
- They all make a reappearance in a filler episode where they use their masks for breathing underwater, and we actually see one without his mask. It later turns out that Hanzo, their village leader (until Pain takes over), wears one as well. Even later, we find out it's not just to let him breathe underwater; it also prevents others from being affected by his poison breath and he himself from being temporarily paralyzed by the poison released if the transplanted organ he implanted in his abdomen which make it is ruptured.
- When we first see these (book 2 or episode 6), they're worn by the Demon Brothers from a rogue faction of the Hidden Mist village. There, they're more clearly compact rebreathers and are used as such (the Brothers were hiding in a puddle).
- The samurai from the Land of Iron eventually turn out to be this, though it's a long time before we find out those helmets have gas masks in them (they're also Red Shirt rather than Mooks, being good guys when we see them).
- In Trigun, the bandit villain Brilliant Dynamites Neon has an army of bandits who serve him, all of whom wear gas masks. This is mostly due to the fact that he uses gas to knock out crews on the sand steamers that he robs. It turns against him when Meryl and Millie beat up two mooks and steal their outfits.
- Both played straight and inverted in Desert Punk: the mooks wear gas masks when they're outside, but so does everyone else. They also serve an actual purpose, as, besides working as actual gas masks against frequent poison attacks, they have built in binoculars and personal air-conditioning units.
- The regular-level soldiers in Hellsing wear gas masks. The Nazi Vampires also wear them...as protection from the sunlight. At night, they don't wear them, though many of them pull scarves up over their face, presumably because it looks totally awesome.
- The ordinary soldiers of the Britannian army in Code Geass wear gas masks as part of their uniform. They don't get attention in the series often, in battles that are mostly decided with Knightmares, but for some reason, their opaque masks never gain significance even though they could block the protagonist's mind control powers.
- In Cowboy Bebop, the temperatures on Callisto are so frigid that many wear masks outdoors. A large gang of them mistake forever-broke Spike for a cash-laden Vicious and attempt to rob him. This does not end well for them.
- In Nausicaš of the Valley of the Wind, the manga and the movie, almost everyone carries gas masks in order to deal with the highly toxic atmosphere of the Sea of Corruption. Wormhandlers and Torumekian grunts, however, rarely take them off.
- Digimon Xros Wars has Troopmon. Supplementary material elaborates that they are actually comprised of energy stolen from other Digimon stuffed in the rubber suit-gas mask combo, and when destroyed, that energy is just recollected and reused, making them an interesting variation of this trope.
- Caesar Clown's mooks in One Piece were introduced this way, wearing rather creepy gas masks. It's justified in this case, however, because Caesar's powers (and their armaments) are all based around gass based weapons.
- Bunky Echohawk is fond of drawing these.
- Nort soldiers in Rogue Trooper almost always wear gas masks. Justified because the atmosphere of Nu-Earth is poisonous to normal humans.
- Used, lampshaded, justified, subverted, and used as a Chekhov's Gun in a Buck Danny comic, when he is escorted by russian guards in full chemical warfare gear. He manages to escape from them briefly to give a warning signal. The Big Bad demands why his lieutenant dressed the Mooks like that, and the man cites that the KGB handbook says it has a good intimidation factor. The Big Bad is angry that the man thinks that someone like Buck would be frightened of some overalls. In the end, it turns out the lieutenant was on Buck's side from the start and meant for him to give the warning.
- The Front Line Group wore gas masks to hide their identities when they first showed up in No Hero.
- In All Fall Down, the Order of Despots' minions are all equipped with their stand issue, needlessly creepy gas masks.
- Black Spectre, a Nebulous Evil Organization that primarily antagonizes Daredevil, has its agents wear gas mask/helmets that include full face visors.
- The invading human forces in The Conversion Bureau: Cold War are decked out in full NBC (Nuclear Biological Chemical) gear, which helps great against the potion throwing guards. Though the suits can still be torn by arrows.
Film — Animation
- In the Disney animated feature Atlantis The Lost Empire, the villain's loyal mooks wore gas masks throughout the entire film (even though it's set in 1914 — before gas warfare was actually used). Likely reasons include ease of animation and dehumanization to make them acceptable casualties. (Plus, while gas warfare wasn't used, running into gas pockets was a likely hazard).
- Gas had not been deployed as a weapon yet, but the concept of a gas mask dates back to the 9th century. A gas mask was patented in America in 1849 by Lewis Haslett, for filtering dust, while Garrett A. Morgan invented a gas mask in 1912 that proved useful for gas/smoke-filled environments.
- The soldiers of the evil Wizard Blackwolf in Ralph Bakshi's animated film Wizards. Yes, you saw it right, they work for a wizard and they wear World War I gas masks. Two of these mooks get the best scene in the whole movie:
Max: Fritz, get up for God's sake! Get up! They've killed Fritz! They've killed Fritz! (draws gun) Those lousy, stinking yellow fairies! Those horrible atrocity-filled vermin! Those despicable animal warmongers! They've killed Fritz! (starts shooting off-screen) Take that! Take that! (Fritz gets up) Take that, you green slime! You black-hearted, sharp, bow-legged—
Fritz: Max, Max, I'm okay. I'm okay, Max. Just a scratch; look, I'm all right.
Max: Oh. Oh, damn. There you go again, stepping on my lines, raining on my parade, costing me medals. Oh, damn. (gun misfires, killing Fritz) Ooh. Oh, Fritz?
- The eponymous soldiers of The Kerberos Saga (which spans multiple media but is included here due to the Adaptation Displacement of Jin-Roh: The Wolf Brigade) are an aversion of the "mook" half of this trope, as an attentive viewer will notice that A) every single brigade member has a distinct personality and backstory, B) the inhumanity given to them by their status as "dogs" is often implied to make them morally superior to humans, and C) no troopers ever die in the series while their mask is still on..
- Interstella 5555: The 5tory of the 5ecret 5tar 5ystem: The mooks sent by the Earl de Darkwood to kidnap the band are wearing gas masks. Justified, however, as they do use sleeping gas weapons to put down the opposition and capture their quarry alive and unharmed. It also hides for some time the ironic fact that they are humans kidnapping aliens.
- In Hoodwinked Too: Hood Vs. Evil, the resident Gas Mask Mooks are none other than Three Little Pigs reimagined as bazooka-toting mercenaries.
Film — Live-Action
- The first Resident Evil movie begins with a squadron of faceless goons abseiling in the windows via different camera angles.
- In Iron Sky the Nazis are seen wearing gas masks as they load up into their flying saucers.
- The Crazies: In both the original and the remake, all of the soldiers wear gas masks, although the Trixy virus is spread via drinking infected water. The soldiers wear them in case the virus has gone airborne and to hide their identities from the public.
- Ultraviolet (2006) features an assortment of Faceless Goons, many of whom wear gas masks as their identity-concealer of choice. These include Big Bad Daxus' personal platoon (who are specifically referred to as "the Gas Guard" in a semi-important manner, even though they turn out to be just regular Mooks wearing gas masks instead of motorcycle helmets), as well as a dozen white-clad Elite Mooks who try to fight Violet using katanas instead of firearms (and end up doing a rather lousy job of it). Although the gas masks are somewhat handwaved in that the film takes place amid massive paranoia about a highly infectious blood-based disease, it's not clear why these particular goons feel obliged to protect their purity of essence with gas masks, instead of being content with the cloth surgical masks or motorcycle helmets most of the other Mooks use.
- The Russian stormtroopers in the Hitman movie wear gas masks and football-gear-based armor straight out of Jin-roh: The Wolf Brigade. Just in case they ever need to storm another opera house.
- Repo! The Genetic Opera has Rotti's henchgirls donning gas masks in Things You See in a Graveyard. Justified as they're throwing tear gas grenades.
- The opening scene in Ian McKellen's Richard III has Richard's commandos wearing gas masks. Of course, this is to allow a Dramatic Reveal of the villain during the opening titles. (Bonus feature: compare that opening to the first shots of A New Hope.)
- The tractor drivers in The Grapes of Wrath. Incidentally, the driver who talks to Muley just wears goggles.
- The Stormtroopers from Star Wars. Probably the example people think of about this trope, or at least high on the list of candidates.
- Flash Gordon (1980). The soldiers in Ming's palace.
- Justified in Avatar, as the toxic atmosphere requires some form of rebreather. However, the masks worn in the film are flat and not concealing at all.
- The Gravers in Phantasm films wear gas masks. Reggie fights one in a chainsaw battle in the second movie.
- The zombie German soldiers in the World War One sequence in Sucker Punch.
- HYDRA's forces in Captain America: The First Avenger.
- The opening attack on the Afghan village in The Beast Of War has the Soviet protagonists all wearing gas masks, partly because of all the dust kicked up by their tanks, but also because they're using Deadly Gas.
- The League of Gentlemen (1960). The ex-soldiers-turned-bank robbers wear gas masks during The Caper, because they're using tear gas to cover their withdrawal from the bank, as well as to scare bystanders into compliance and hide their identities.
- In The Running Man, all the guards in the detention zone at the start wear gas masks and protective goggles. They do have a good reason however, considering all the unhealthy stuff in the air from the old industrial complex. The prisoners are less fortunate.
- A rare heroic example in The Hunger Games: Mockingjay Part 1 when the rescue team from District 13 arrives at the Capitol to rescue Peeta and the other captured victors. The gas masks help protect the team from knockout gas they use on Peacekeepers during the operation.
- Batman has a futuristic example in the Wayne Manor armory. Disconcertingly, it's just there, practically begging for some kind of backstory. Did Bruce make it as an art project of some kind? Is it a Wayne Industries prototype? Or did it come from a horrifying, still-recent chemical war? We may never know.
- World War Z: In the Battle at Yonkers, the Army brass decide to invoke this trope in order to create the appearance for the news cameras that the US Army troopers are invincible killing machines that are ready to mow down the shambling zombie hordes. On top of the MOPP-4 masks was layered body armor and the latest in satellite commo gear. It fails miserably — as told by a line infantryman, all this succeeded in doing is making every grunt on the line more tired, overheated, and inaccurate due to trying to shoot while wearing all that junk. That was just the infantry: the armor, artillery, close air support, and engineering divisions had also been selected and loaded for maximum visual effect and bragging rights for the news crews as opposed to maximum efficiency in actually destroying zombies.
- Brave New World features an interesting variation. Riot police wear gas masks as they spray relaxing gas ('Soma', which is a common relaxant in the story), and then play a record of calming narration to dispel mobs, which fits with the novel's theme of dystopian control without direct oppression or bloodshed.
- Federation troopers in Blake's 7 — although some do remove their helmets.
- The Breen from the Star Trek franchise (especially Star Trek: Deep Space Nine). Explained by their homeworld being a frozen wasteland having a rather noxious atmosphere outside of which they can't survive. Although a few characters claim to have visited the Breen homeworld and say that it's actually perfectly habitable and at a comfortable temperature. The Breen apparently wear their environment suits and masks just to appear enigmatic. It is said that no outsider has ever seen what one looks like beneath their masks and lived to tell of it.
- On Babylon 5, the Babylon 5 security personnel could be considered such by certain aliens, since parts of the station are filled with atmospheres for various exotic aliens, requiring oxygen-breathers to wear special masks (or to get gill implants, as some elect to do instead).
- An interesting example is Kamen Rider: The First. The mooks wear Gas Masks, but are killed just as easily as in their skeleton-costume days (and they give the same "yee!" shout as they hop around!) The Shocker Greeed in Let's Go Kamen Riders has a gas mask apparently as homage, though The First and The Next aren't in main series continuity. Fewer appear in Kamen Rider: The Next and mostly in a non-combat role with foodsoldier work largely left to the Shocker Riders.
- The colorful Wumpers in Gekisou Sentai Carranger look like they have gas masks. They made limited appearances in Power Rangers Turbo as General Havoc's robots, and a whitewashed one was used as the (ironically color-obsessed) and rather tough Monster of the Week, Chromite. To sentai fans, it must have looked like the Rangers were being owned by a single Putty Patroller.
- [adult swim] — They're smokin'!
- Borderline example: "The Empty Child"/"The Doctor Dances" on Doctor Who set during World War II. The "monster", a small boy, wore a gas-mask and was actually a zombie, who could control technology, could only say the words "Are you my mummy?", and could convert everyone else to be just like him. Nothing says fun like watching a grown man gag as a gas-mask forces its way up his throat.
- Arrow: The armoured car bandits in "Trust but Verify", although they are actually using tear gas as part of their heists.
- Psychopathic Records rapper Jumpsteady typically appears in a bodysuit with gas mask when he associates with Insane Clown Posse.
- Gas masks are a repeated visual in Frank Zappa's music, including the liner notes for Joe's Garage and the concert film Baby Snakes.
- Weasels Ripped My Flesh included a song called "Prelude to the Afternoon of a Sexually Aroused Gas Mask."
- A gas mask is the Iconic Item of Norwegian alternative rock band Kaizers Orchestra and is a common element in album art designs, sometimes cleverly hidden. The mask is worn by their organist during live performances.
- One constant about Thrash metal band Sodom's soldier mascot Knarrenheinz is the gasmask he wears.
- Warhammer 40,000
- Armageddon Steel Legion and the Death Korps of Krieg, among other Imperial Guard legions. Then again, they tend to live in places where the masks are a good idea for survival in general.
- The Death Korps also wear them to hide the fact that they're clones, a practice which is frowned upon in the rest of the Imperium.
- In Dan Abnett's Gaunt's Ghosts novel Straight Silver, both sides make extensive use of gas masks. Then again, they need them.
- The Chaos cultists in the Dark Vengeance box have a mixture of gas masks and other, cruder face-covering devices.
- Some Plague Marines have helmets reminiscent of gas masks.
- Warhammer Fantasy includes specialized Skaven wearing gas masks for protection against various airborne ills of their own devising; they are not named characters, making them mooks, but they are generally not cannon fodder, either.
- A lot of d20Modern artwork shows military-looking mooks (mercenaries?) in gas masks, apparently just for Rule of Cool. (PCs using chemical weapons are extremely rare, but it can happen.)
- The Combine Overwatch soldiers and Civil Protection officers in Half-Life 2, as demonstrated above. Apparently, an early version of the script had City 17's air unbreathable, so that everyone wore gas masks. This was dropped, but the Combine gas masks weren't. It should also be pointed out that Overwatch soldiers required the mask to include their vocoder, due to their vocal cords being ripped out (visible when you see the topless Overwatch model in Nova Prospekt), and Civil Protection officers would need them for anonymity, due to being rather brutal to citizens. The Gas Masks actually work against them at times. Using the "'bug bait" on a normal person gets no reaction, but using it on a Civil Protection Officer or an Overwatch Soldier causes them to flail about, apparently choking. That might just be because they're Friendly Fire Proof.
- Some of the marines in the original Half-Life also wore gas masks (including Adrian Shephard in Opposing Force).note
- The mourners in RuneScape.
- In Far Cry for the PC, the toughest enemy soldiers are Elite Mooks who are identified by the gas masks they wear. Why they do so is something of a mystery, as chemical weapons are never a factor, and it turns out that the mutagen the bad guys are toying with isn't even airborne.
- From the Wolfenstein series:
- In Return to Castle Wolfenstein, heavily armored Venom Troopers wear long greatcoats and gas masks. It's unclear why they do so, as none of the other enemy soldiers wear any sort of NBC gear. The gas masks only seem to serve as a message to the player that these guys can soak more bullets than normal soldiers.
- Same goes for the Drache Troopers in Wolfenstein, though, in their case, it could at least be argued that they need them to filter out the smoke produced by their flamethrowers (especially since they have a tendency to use them in confined spaces). The Veil Assassins and Heavy Troopers have no such excuse, though; rather, they wear gas masks because they are not exactly human anymore.
- Borderlands: Some of the Atlas soldiers appear to be wearing gas masks. Far more visible (and numerous) in the Secret Armory of General Knoxx DLC.
- Medal of Honor
- Likewise, in Medal of Honor: Airborne, the Mini-Boss-like Panzergrenadiers (guys with rocket launchers) and Nazi Storm Elites (guys with heavy body armor wielding MG 42 machine gun turrets as portable weapons!) wear gas masks for no apparent reason other than to signal that they're supposed to be badass.
- Medal of Honor: Allied Assault has a rare justified example: the only soldiers wearing gas masks are the ones guarding the interior of the mustard gas factory in the game's final mission.
- In Deus Ex, some of the soldiers seem to incorporate light gas masks into their mouthpiece headgear. Oddly, these don't seem to provide any actual protection against tear gas grenades, or even against pepper spray. That might be because tear gas and pepper spray are eye irritants — since there's a global pandemic going on, it's probably not for protection against chemicals at all.
- In Iron Storm, enemy Siberian Troopers wear gas masks and heavy body armor. As per usual, the gas masks serve mostly to signal they're badass (they carry mini-rocket launchers that gib you in one hit) rather than to protect against NBC weapons. In fact, their gas masks are purely cosmetic and provide absolutely no protection against mustard gas grenades or LSD gas grenades.
- Umbrella Special Forces operative Hunk from the Resident Evil series is a rare example of a Gas Mask Mook with a name and his own story.
- Some late-game mooks in Resident Evil 4 and Resident Evil 5 wear gas masks. In 4, they're disturbingly sewed to Ganados' faces and make it slightly harder for Ada and Leon to elbow off their heads, whereas the ones in 5 protect against headshots and make them immune to flash grenades. There's no reason for them in "5", although it's implied to be justified in "4": the exposed flesh of the gas mask wearing enemies is horribly mutilated, presumably from chemicals, and they can't take them off because, well, they're sewed on.
- Henderson Security from Supernormal Step
- The masks in this case were originally intended to avert the dehumanization associated with this trope because they served as a means of preventing racial tension towards Henderson Security's diverse work force. By the time of the comic, however, this had become a minor issue and the masks were simply maintained as a symbol of their position. For the reader, the masks are meant to have the typical effect.
- Every single character in Gone with the Blastwave is one of these, unless you want to count the giant mutant moth. The markings on their helmets, which seem to indicate their roles in the unit, are the only way to tell them apart. It's not clear whether this is just a defensive measure in the war they're fighting or whether the post-apocalyptic setting makes it necessary for survival. Either way, it adds to the general theme of the characters being faceless mooks in a war they don't understand or particularly care about. Page 50 filler shows "25 essential expressions" on these.
- The four protagonists of Romantically Apocalyptic (Sniper, Captain, Pilot, and Engineer) all wear gasmasks, though this may be because of the rather eccentric captain. Lampshaded in a flashback scene in which a pre-apocalypse child version of Captain still insists on wearing a gasmask.
- The members of Senator Madder's "security detail" in Tales Of Gnosis College appear to be Gas Mask Mooks.
- The Fear Mythos: one of the Archangel's recurring minions is a gas-masked sniper.
- Destro's Iron Grenadiers from G.I. Joe.
- In Rudolf Ising's 1939 anti-war cartoon Peace on Earth, the now-anthropomorphic animals recall how Man finally wiped himself out in one final war. The grimness of these sequences is hyper-accentuated by their never-removed gas-masks which seem to run the length of their whole bodies- Grandpa thinks that the gas masks were actually "great, long snoots, which fastened on to their stomachs", a sufficiently horrifying description, when combined with the masks mirrored lenses ("...and their eyes flashed!") to creep out at least one grandkid. The two last ones shoot each other dead before falling into the muck and mud, ever faceless.
- The Equalists from The Legend of Korra. Rather unusually, as there doesn't seem to be any particular reason for them to be wearing gas masks — at least, not yet.
- As of Season 1 Episode 3 "The Revelation", they do have a reason. A pair of Badass Bikers throw some kind of gas grenades/smoke bombs to cover their escape, and their masks protect them from the green gas. The masks also fit with the anonymity cultivated by their leader Amon, who wears a White Mask of Doom, albeit an opera mask not a gas mask.
- Kuvira's army in Season 4 has thousands of these acting as her rank-and-file grunts.
- The Terras in Motorcity wear these, as their faces are mutated due to toxic waste dumped by Kane Co.
- Very much a Truth in Television, as various SWAT and Counter terrorist teams wear gas masks regardless of whether they're going to use gas or not. Two reasons for this: a) preventative measures in case who they're going against does or if they themselves decide to use tear gas or smoke grenades and dust that would be thrown up by entry charges and b) the psychological effect it has on the enemy inside the building they're about to storm. Many gas masks are also compatible with flash reduction lenses, which means the wearer is less vulnerable to flash grenades.
- Possibly the most iconic example would be the Iranian Embassy Siege, where Special Air Service operators retook the embassy after a six-day siege. One of the more iconic images of the event were the images◊ people watching the news or reading the paper got to see of darkly-dressed SAS operatives wielding MP5 submachine guns and sporting bug-eyed lens gas-masks. It's a look that has carried over to a lot of other media depicting counter-terrorist and special operations forces.
- It's not wholly fair to call them evil, but they're almost certainly the source of this trope: during World War I, a lot of German soldiers wore gas masks because of all the chlorine gas they were using in battle, most famously at Ypres.
- In the awkward segue between horse and vehicle warfare, horses sported some variety of mask.
- The Allies started to issue gas masks once they were fully developed. They didn't wear them constantly because they were incredibly uncomfortable, and you could actually choke in one if you didn't switch the filters often enough.
- The above Philip K Dick quote comes from the notes of one of his stories, where he is remembering his father, a World War I veteran, showing him the mask when he was a child.
- The US Marines have a nickname they're fond of that they claim to have been given by the Germans, Teufel Hunden, meaning "Devil Dogs", attributed to reports from the Battle of Belleau Wood where Marines wore bulky gas masks and clawed their way up a steep hill to get at the Germans, foaming at the mouths from the heat and exertion. Supposedly, this gave them a hellish, dog-like appearance. note .
- "Teufelshunde" is actually gramatically correct German.
- Chemical weapons were not used prominently in Europe during World War II, not even by Nazi Germany, because, aside from the majority of German transport being comprised of horses, both sides had lived through such a horrible experience with them in the last war that they were terrified of using them again. There was a tacit understanding that if either side started using chemical weapons, the other side would retaliate with their own chemical weapons, and escalation would soon lead to whole armies and entire cities being nerve gassed. Each side had spent the past two decades living with thousands of wounded soldiers crippled by exposure to poison gas, the reality of these weapons had really hit home, so they never seriously considered using them.
- That wasn't to say that the Germans didn't have poison gas - they made tons of the stuff, but Hitler refused to use it (because of his own experience with gas in WWI). The UK also stockpiled chemical arms, which would have been used against a German invasion.
- Even the Japanese, who hadn't fought on the Western Front and who were willing to use chemical and biological weapons against the Chinese, were terrified that the United States would resort to chemical warfare attacks against their defensive tunnels on the Home Islands. This is why they never used chemical weapons, even when their home territory like Okinawa was being invaded. Their military central command issued explicit orders never to do anything that might provoke the Americans into using chemical weapons, such as specifically using chemical weapons on American troops.
- Of course, the much more mobile nature of WWII combat also made chemical weapons far less useful. It's easy to resist the temptation to use gas when it doesn't do much good anyway.
- Despite all this, most nations of WWII developed their own gas mask technology further to protect the wearer more effectively. Just in case.
- Iraqi soldiers fit this well enough as they utilized chemical weapons against Iran.
- As well as against Kurdish villages on their own territory.
- During the Cold War, every country manufactured masks to protect themselves from chemical and biological weapons. The Soviets created many masks that represented human skulls which were intended to also have a psychological impact on enemy troops. These mask designs were used in Half-Life 2 and other dystopian fiction. Also, many Russian families keep these skull masks just in case, and Russian truckers like to put these masks on the necks of their trucks' diesel tanks.
- The particular mask worn by Civil Protection from Half-Life 2 is called ShMG Nerekhta. Here are some real life photos of one.
- Even after the Cold War, new masks are being designed and produced, as various improvements are made (usually in terms of comfort and durability) and old equipment wears out or becomes obsolete.
