Call of Duty: World at War
|
Call of Duty: World at War is the sixth main Call of Duty game and the second by Treyarch, starting their Black Ops story arc. Released in 2008, it is the last Call of Duty game set primarily in the Second World War until Call of Duty: WWII nine years later. The game features two campaigns, one in the Pacific theatre and the other in the Soviet Union; a British campaign was also planned, but cut due to lack of time (this also caused the much-hated level "Blowtorch and Corkscrew" to be farmed out to Pi Studios, who were responsible for the multiplayer maps of Wolfenstein).
The following weapons appear in the video game Call of Duty: World at War:
Overview
World at War shares many of the weapon/loadout mechanics of Modern Warfare, including the "Create-a-Class" system. Per the WWII setting, the "sniper rifles" and "assault rifles" categories are renamed to "bolt action rifles" and simply "rifles" respectively, the latter category referring to rifles that aren't manually operated. WWII-era attachment options for weapons also are available in this game, with select weapons having a few new options such as extended magazines, flash suppressors, bayonets, and bipods. The "camouflage" customization option from CoD4 is not found in World at War's multiplayer, only referenced as a cut feature in game files. Interestingly, most weapons found in the "Blowtorch and Corkscrew" mission have a wet, rained-on finish, a trait unique to this specific mission.
World at War is the first game to introduce Nazi Zombies (later known simply as Zombies in later games), a horde survival gamemode where players are pit into surviving waves of endless undead. Additional weapons (as well as ammunition for the same weapon) can be purchased off the walls as a white chalk silhouette and a random weapon can be purchased through the "Mystery Box", which contains weapons that are otherwise not available off the walls and it contains a few fictional and unique powerful "wonder weapons". Rather than attachments, players can upgrade their weapons through the "Pack-A-Punch" machine only available in "Der Riese", giving them massive stat buffs as well as special abilities for some weapons. Weapons that are upgraded through Pack-A-Punch will have intricate engravings on the metal, one of the few instances where a "camouflage" of sorts is used in the game (along with the muddied finish, mentioned above).
Melee attacks are performed with knives as opposed to bludgeoning with the current weapon as with CoD4, though using the bayonet attachment for most weapons allows the player to perform quick lunges and stabs. Finding the Bowie Knife in Nazi Zombies allows increased melee damage, this replaces the standard knife entirely.
Handguns
Colt M1911 Hybrid
A confusing and anachronistic M1911 variant is the sidearm of the US Marines in the game and is given to playable character Pvt. Miller in the missions "Little Resistance" and "Hard Landing". It holds eight rounds when a real M1911 from the period would only hold seven (plus one in the chamber); while standard-size eight-round magazines are available, they were not produced until the 1980s. The ammunition capacity in the game is likely a game balancing decision to make the pistol equal to the other sidearms in the game, which all hold 8 rounds. The M1911 also has a straight mainspring housing and a short trigger, indicating an anachronistic Series 80 frame. As such, the pistol has an A1 slide and trigger, a Series 80 frame and an eight-round magazine from the 1980s - a combination unlikely to be found in the hand of a WWII GI. The M1911 variant is the starting weapon in Nazi Zombies in all maps.
A secret M1911 variant called the "Holy Pistol" can be used in the Nazi Zombies map "Nacht Der Untoten" on the PC, by using the "Give All" PC command. It is a visually-identical M1911 that fires high-explosive grenades, and as such is similar to the upgraded M1911s obtained by putting the standard pistol into the "Pack-a-Punch" machines found in the Zombies maps of later games (although these also had an altered appearance).
Nambu Type 14
The Nambu Type 14 Transition model is the sidearm used by Imperial Japanese forces in the game. It is the very first firearm obtained in the game, given to the player by Sgt. Sullivan at the beginning of the mission "Semper Fi". The pistol also makes an appearance at the end of the mission after Miller is wounded by a Japanese soldier with a katana, regardless of whether or not the player replaced it during the course of the level. Like most sidearms, the weapon is fairly uncommon and the best way to obtain one is by taking it from a wounded enemy who has entered "Last Stand" mode.
Smith & Wesson Model 27
The most powerful handgun in the game is the Smith & Wesson Model 27 with the front sight and grip of the older Smith & Wesson .357 Registered Magnum, the predecessor of the Model 27. It is only available in multiplayer and can be given by the random weapons box in Nazi Zombies. It should be noted that the Model 27/Registered Magnum never actually saw active service; only US Army General George S. Patton was known to carry a S&W .357 Magnum during WW2. A more realistic choice of service revolver would have been a Smith & Wesson Model 10 or an M1917.
Tokarev TT-33
The Tokarev TT-33 is the sidearm of the Red Army and is given to playable character Pvt. Petrenko in the missions "Their Land, Their Blood", "Ring of Steel", "Eviction" and "Downfall". The weapon is fairly effective in the close quarter fighting of the Soviet campaign but due to a lack of ammunition, its use is limited. NPCs may also be seen using the weapon on rare occasions.
Walther P38
The Walther P38 is the standard sidearm of German forces in the game. One can be picked up in the mission "Vendetta" and can be used to unlock the achievement/trophy "Gun Slinger". The weapon is also used against the player at the end of the mission "Downfall" as he is attempting to plant the Soviet flag on the roof of the Reichstag. Like the Nambu Type 14, the weapon is fairly uncommon and the best way to obtain is from enemies who have entered "Last Stand" mode.
Submachine Guns
MP 40
The MP 40 is the primary submachine gun used by the Germans and is seen in every mission of the Soviet campaign. The "dual magazines" attachment is available in multiplayer, effectively giving it the MP 40/I Dual Magazine System, though it incorrectly fires both magazines continuously and is treated like an extended magazine. A sound suppressor and "Aperture Sight" can also be added in MP.
In multiplayer, the MP 40 quickly become infamous as one of the strongest weapons in the game, with preferred class set ups adding the dual magazine attachment and pairing it with the Stopping Power or Juggernaut perks, which increase bullet damage and increase player health, respectively. Stopping Power allows the MP 40 to kill in two shots at much longer ranges than other SMGs, while using Juggernaut allowed for players to have a better chance to win close range gunfights as the MP 40 on consoles deals over 50 damage per shot at close range, allowing for two shot kills when most other weapons need three shots to kill.
PPSh-41
The PPSh-41 is the primary weapon of Sgt. Reznov and first seen in the mission "Vendetta", after he gives Petrenko a scoped Mosin-Nagant. It is also the standard Soviet submachine gun and can be found in abundance towards the end of the Soviet campaign. The version used in single-player and Nazi Zombies is loaded with the weapon's trademark 71-round drum magazine while the one available in multiplayer instead uses the smaller 35-round stick magazine by default; the drum magazine has to be unlocked as an attachment. As the "Round Drum" attachment simply doubles the size of the base magazine, the drum holds 70 rounds instead of 71, which is the capacity of the singleplayer and zombies drum.
Thompson M1A1
The Thompson M1A1 fitted with a Cutts compensator is the primary submachine gun used by American forces and is Sgt. Roebuck's main weapon. In-game, the weapon is visibly modeled with a 30-round magazine, but it only holds 20 rounds, while the "Round Drum" attachment doubles this to 40. Thompson drums did not hold 40 (unless you underloaded it), the 40 round capacity is due to the game simply doubling the base capacity when the extended magazine attachment is used. Additionally the M1A1 physically cannot be loaded with a drum magazine - this is a feature of the older M1928 Thompson. The Create-a-Class icon shows the Thompson without the Cutts compensator. It is slightly anachronistic to the mission "Semper Fi" taking place in August 1942; during that time, the earlier Thompson M1 was in use, while the M1A1 was adopted two months later. It is also anachronistic for the pre-October 1942 multiplayer maps.
Type 100
The Type 100 is the primary Japanese submachine gun. It seems to be the 1944 model, making its appearance in "Semper Fi", set in 1942, anachronistic. They are also far too common, being depicted as a standard infantry weapon, in the hands of around a third of all Japanese soldiers. It is also anachronistic for the pre-1944 multiplayer maps. Notably, it is held improperly by the magazine by the player character, but properly in third person. Confusingly, enemies with the Type 100 sometimes banzai charge the player, despite the fact that the weapon is never fitted with a bayonet. In multiplayer, a suppressor, "Aperture Sight," and extended "Box Magazine" can be unlocked for the Type 100, with the latter doubling capacity from 30 to 60.
Shotguns
Double-barreled shotgun
A full-size Double-barreled shotgun appears in the subway, lying around in the offices. Like the Winchester Model 1897, it is devastating at close range, capable of blowing off heads and limbs. When firing, the weapon incorrectly ejects a spent cartridge (and to top it off, it is a rifle round as opposed to a shotgun shell), which is impossible with real double-barreled shotguns as they have no ejection port and need to have their shells removed manually (although some are capable of automatically ejecting shells once the barrels have been broken open). When the weapon is reloaded, it acts as if none of the shells have been ejected and any empty cartridges (this time being proper shotgun shells) will still be inside the gun and are removed manually. The Create-a-Class description in multiplayer states that the weapon is American, although it is found in Eastern Front missions in the campaign.
Sawn-off double-barreled shotgun
The "Sawed-Off" optional attachment for the double-barreled shotgun is self-explanatory. In the campaign, this version appears in the asylum in "Ring of Steel," found in the kitchen.
Winchester Model 1897 Trench Gun
Referred to in-game as the "M1897 Trench Gun", the Winchester Model 1897 "Trench Gun" is Sgt. Sullivan's primary weapon and can be found in numerous American levels. Interestingly, it has different magazine sizes in both single-player (six rounds) and multiplayer (four rounds), neither of which is actually correct (the real weapon holds five rounds in the tube magazine, plus one in the chamber; considering how the weapon in-game is always pumped at the end of a reload, the 6-round capacity could not possibly be 5+1, as pumping the weapon would eject the chambered shell). A vertical foregrip (which appears to be a simple wooden handle haphazardly drilled into the original forend) and a M1917 bayonet can be unlocked for use with the Trench Gun in multiplayer.
Rifles & Carbines
As mentioned earlier, rifles in this game are divided into "bolt action rifles" and "rifles". However, the "bolt action rifle" category incorrectly includes the PTRS-41, which is a semi-automatic anti-tank rifle (though one can make the argument since the PTRS in-game has a lower rate of fire compared to the other semi-automatic rifles, likely for balancing purposes).
Arisaka Type 99
The Arisaka Type 99 is the main rifle for the Japanese. Banzai attackers attach Model 30 bayonets to their Arisakas, which are then called "Arisaka Bayonet." A scoped version can also be found in the missions "Semper Fi", "Burn 'em Out" and "Blowtorch and Corkscrew". The weapon is modelled on the earlier Type 99 rifles as it has the monopod, flip up anti-aircraft rear sight, protected front sight, and a plum shaped bolt handle.
FG 42/I
The FG 42/I appears under the machine guns category, and is the only weapon in this class that can be equipped with a telescopic sight. It incorrectly has a 32-round magazine in single-player; this is corrected to 20 rounds in multiplayer. It is also anachronistic for the pre-1943 multiplayer maps.
Gewehr 43
The Gewehr 43 is the secondary rifle for the Germans and is seen in the missions "Their Land, Their Blood", "Ring of Steel", "Heart of the Reich" and "Downfall". As expected, there are still bullets in the magazine that the player removes when reloading, even if the last shot was fired. It is also anachronistic for the pre-1943 multiplayer maps.
Karabiner 98k
The Karabiner 98k is the main rifle for the German Army. The weapon appears to be modelled after one of the earlier models and not the "Kriegsmodell" as it has a bolt disassembly disc, spring retained barrel bands, cleaning rod, and a protected front sight. It also has a manufacture date of 1944 as well as "DOT" written on the top of the reciever, indicating it is a Waffenwerke Brunn rifle produced in Czechoslovakia.
M1 Carbine
The M1 Carbine is the secondary rifle of American forces and is rarely seen until the mission "Breaking Point", where it can be picked up from most of the American corpses. It is erroneously called an "M1A1 Carbine" in-game, despite not having a folding stock. In MP, unlockable attachments for the carbine include an M3 Carbine-style flash hider, an "Aperture Sight," bayonet, and a 30 round extended box magazine.
M1 Garand
The M1 Garand is the standard rifle of the American forces, and is seen in the hands of nearly all of the American Marines. It is depicted as being able to reload partway through an en-bloc clip; while there is facility for unloading the gun without firing every shot, it was not considered practical to do so in combat (since real soldiers don't have a magic invisible ammo hopper that consolidate their spare ammunition neatly into full clips) and American soldiers were generally advised to fire off remaining shots if reloading was necessary. In-game, this is represented by having a mid-clip reload take longer than an empty reload. In addition to a flash hider, bayonet, and rifle grenades, a sniper scope can be unlocked for the Garand in multiplayer, giving it the appearance of the M1C sniper variant.
Mosin Nagant M38 Carbine
The Mosin Nagant M38 Carbine is first given to Petrenko fitted with a scope by Reznov in the mission "Vendetta". In later missions the rifle is found in the hands of Russian soldiers. They are rather abundant in early missions but get scarcer as the game goes on. Due to a graphical error, the bolt never actually opens to expose the breech until the player prepares to load a clip; otherwise it remains solid metal and casings do not actually eject from the rifle itself. All M38's are fitted with downturned bolt handles meant to work with sniper scopes, even the ones that don't have scopes. While not anachronistic, this model of the Mosin Nagant being used is inaccurate due to the M91/30 variant being the standard issue rifle for Soviet forces during the 1930s and throughout World War II. The M38 carbine variant served as a weapon for rear echelon troops.
PTRS-41
The PTRS-41 is always seen with a scope, and as with multiple optic-equipped weapons in the Call of Duty series, the front sight is missing. However, the real rifle was never issued with a scope, apart from field-expedient modifications, which were for spotting purposes only; these scopes were typically PU scopes, not meant for the PTRS, and as such couldn't be properly zeroed (note that in the iOS counterpart Call of Duty: Zombies, the weapon lacks the scope and appropriately uses iron sights, though it has a front sight mounted on the gas block rather than the end of the barrel). The PTRS is first seen in single player during "Vendetta" and much later in "Heart of the Reich" and "Downfall". It is ridiculous to depict a single man firing this weapon from the shoulder; the PTRS-41 is six feet long and weighs forty-five pounds, and unless he was an absolute giant of a man, the immense recoil produced when firing would knock him on his back. A single soldier would only ever be expected to be able to carry the fully assembled rifle for short distances.
Springfield M1903A1
The Springfield M1903A1 is never seen in single player without a scope, and comes with a scope that can be unlocked in multiplayer. The rifle is not an M1903A4 as it is based off of an A1 and mounts a higher-powered scope than the M73 and M84 scopes commonly used on the A4 variant. The scope mounts are also moved forward towards the barrel and forward receiver to accommodate for its length. The A1 sniper variant was more common in the Pacific (as it was the standard sniper rifle of the USMC), which is why it is also seen in other games set in that theatre rather than the A4.
Sturmgewehr 44
The Sturmgewehr 44 is the main support weapon used by the Germans and the only assault rifle in the game. It is rare in earlier levels but becomes more widespread towards the end of the Russian campaign. It is also anachronistic for the pre-1943 multiplayer maps.
Tokarev SVT-40
The secondary Russian rifle is the Tokarev SVT-40. It is seen only in the final two missions "Heart of the Reich" and "Downfall". In multiplayer mode, The SVT-40 is available for the "Rifleman" class; one of the three starting classes.
Machine Guns
Interestingly, World at War is the only main entry of the series post-COD4 (not including Advanced Warfare) that machine guns are accurately classified as "machine guns" and not "light machine guns" as with later games of the series (including Treyarch's own entries). The "machine guns" category in-game includes the aforementioned FG 42/I, an automatic rifle of sorts. All machine guns (both fixed and portable) are capable of blowing limbs and heads off of enemy soldiers as well as Zombies in the Nazi Zombies game mode.
Browning Automatic Rifle M1918A2
The M1918A2 Browning Automatic Rifle is classed as a machine gun in the game. In single-player it is never seen without a bipod, but this must be unlocked in multiplayer. It is the starting weapon in "Hard Landing", and can also be found in the trenches in "Burn 'em Out" and being carried by some allied Marines in "Breaking Point" and "Relentless".
Browning M1919A4
The Browning M1919A4 is used in both infantry and mounted forms. It is used with a bipod equipped (which was only available for the M1919A6 version) in the mission "Relentless"; it is seen without a bipod later on in single-player. Either way, it would be impractical for it to be used as a man-portable weapon; the M1919A6 variant would have been more suitable for that role. In first-person view, it has a strip of cloth wrapped around the barrel close to the frame acting as a makeshift handguard, but this is absent on the world model. It is the last machine gun unlocked in multiplayer.
The PBY Catalina in "Black Cats" has M1919s dual-mounted in the bow turret and single gun mounted in the tail turret.
Degtyaryev DP-28
The Degtyaryev DP-28 is only featured in multiplayer. It has decent power, but poor aim speed, running speed, and reloading speed.
MG 34
When starting up the game, archival footage of Wehrmacht soldiers firing a MG 34 is shown during the title reels. It is replaced by the man-portable MG 42 in the game.
MG 42
The MG 42 is the main machine gun used by the German Army, found both as a mounted weapon and a man-portable version. The version that can be picked up by the player incorrectly uses a 125-round belt drum in single-player and Nazi Zombies, although this is corrected to 50 rounds in multiplayer. It can be found in the mission "Vendetta" which is set in the Battle of Stalingrad, however, while the MG 42 actually saw limited use at Stalingrad, the game's depiction commits the common error of showing the weapon with the post-1943 vertical charging handle instead of the period-appropriate and rare slab-sided horizontal handle. It is also anachronistic for the pre-1943 multiplayer maps.
Type 99
The Type 99 is the main Japanese light machine gun. It incorrectly holds 32 rounds in single-player, but correctly 30 in multiplayer. The bipod and a bayonet can be unlocked as attachments for the Type 99 in multiplayer.
Launchers
M9A1 Bazooka
Miller picks up an M9A1 Bazooka to destroy the Japanese tanks during the assault on Peleliu airfield in "Hard Landing". It is also used by two Soviet Soldiers in the level "Downfall". It is one of the immediately unlocked Perks when "Create a Class" is unlocked. The sight is incorrectly depicted with a German sniper scope-style reticle.
Panzerfaust
Although not a gameplay weapon, the Panzerfaust appears in the cutscene of the campaign level "Blood and Iron".
Panzerschreck
The Panzerschreck is the main rocket launcher for the German Army and is seen in every mission of the Soviet campaign except "Vendetta". It is not available in multiplayer as an available perk nor weapon, though it does appear in Nazi Zombies.
Flamethrowers
M2 Flamethrower
The player first acquires an M2 Flamethrower from the hands of a fallen Marine who is killed trying to clear a machine gun nest in "Hard Landing". In the levels "Burn Em' Out" and "Blowtorch and Corkscrew", Miller (rather appropriately) starts with the weapon. In The Eastern Front missions "Vendetta", "Heart of the Reich" and "Downfall", German soldiers use the M2, standing for the more accurate Flammenwerfer 35. It has infinite fuel, but to prevent endless streams of fire the weapon is managed by an overheat gauge; firing for too long will fill the gauge, at which point the weapon will refuse to fire until it has cooled down.
Grenades & Explosives
Dyakonov Grenade Launcher
The Dyakonov Rifle Grenade Launcher can be attached to the Mosin Nagant M38 Carbine.
Gewehrgranatengerät Grenade Launcher
The Gewehrgranatengerät Rifle Grenade Launcher can be attached to the Karabiner 98k, the Gewehr 43, and the Arisaka Type 99 rather than the latter's appropriate Type 2 launcher.
M7 Grenade Launcher
The M7 rifle grenade launcher is a muzzle device that attaches to the M1 Garand and is used a few times in the Pacific campaign; the first time is during the mission "Hard Landing" when the American force is attacking Japanese Type 96 25mm triple installations at the airfield on Peleliu Island. It is used to launch Mk 2 hand grenades fitted with M1A1 rifle grenade adapters (this is anachronistic as the M1 adapter, which featured 4 claws and no stabilizing cup, was the only variant used during the war). In multiplayer, it can be attached to the M1 Garand and to the Springfield M1903A1 (which should use an M1 grenade launcher). There is a slight error in how they are presented: mounting one would normally require the rifle to first be emptied, then individual blank cartridges loaded for each shot fired; in-game, they're simply attached and fired.
It also incorrectly allows semi-automatic fire from the Garand while mounted: the wartime M7 could not do this.
AN/M8 HC smoke grenade
The AN/M8 HC smoke grenade is used as the standard smoke grenade in the American campaign.
M18 smoke grenade
The M18 smoke grenade is used as the "Tabun Gas" grenade in multiplayer. Tabun was the first nerve gas ever produced and the first of the "G-series" of non-persistent nerve agents, GA (Tabun), GB (Sarin), GD (Soman) and GF (Cyclosarin), being discovered accidentally by German scientists working on organophosphate insecticides in 1936. While over 12,500 tons of the chemical were produced during the war, it was only ever put into air-dropped bombs and artillery shells, not grenades, and was never used in combat.
M34A1 Mortar Shell
In "Breaking Point," Private Miller can pick up shells from Japanese mortar pits to use as improvised hand grenades. Though rendered as proper Type 100 mortar shells on the ground, they turn into 81mm M34A1 mortar shells in the player's hand.
Mk 2 hand grenade
The Mk 2 hand grenade is the standard American grenade in single-player and is the only frag grenade in multiplayer. It should also be noted that in the first mission, "Semper Fi", the Mk 2 is shown with the olive drab color. This is anachronistic as the mission is set in 1942 and Mk 2 hand grenades were completely yellow prior to 1943.
The Mk 2 grenade icon is also used for the grenade indicator icon, even when the grenade is not a Mk 2.
Model 24 Stielhandgranate
The Model 24 Stielhandgranate "Potato Masher" is the principal hand grenade used by the Germans, and is also the only hand grenade available in the Nazi Zombies mode.
No. 74 Mk. I S.T. Grenade
Though there are no British troops in the game, the British No. 74 S.T. Grenade is available. This is the only in-game remainder of a planned British campaign that was cut for time reasons during development.
RGD-33 hand grenade
The RGD-33 is the standard Soviet hand grenade.
S-Mine
The S-Mine is available in-game, referred to by its famous nickname, the "Bouncing Betty". When placed, it will remain inert until an enemy moves near it, at which point it will leap upwards, before detonating at chest height.
TNT
TNT appears in the game as the main component of mission-specific demolition charges used to destroy specific targets in the campaign and is available in the first perk tier in multiplayer.
Type 97 hand grenade
The Type 97 hand grenade is the main Japanese hand grenade.
Emplaced Weapons
ATO-42 Flamethrower
Dimitri's OT-34/85 tank in "Blood & Iron" is armed with an ATO-42 Flamethrower which replaces the Degtyaryov DT machine gun.
Berezin UBT
Soviet Ilyushin Il-2 ground-attack aircraft are armed with Berezin UBT machine guns.
Browning M2
A Browning M2 fitted with a reflector gunsight is mounted in each of the Catalina's waist blisters in "Black Cats".
Browning M1919A4
M4A1 Sherman tanks have hull-mounted Browning M1919A4s. It is also erroneously shown as the turret gun for the Soviet T-34 tank in both single-player campaign and multiplayer. A more accurate turret gun would be a mounted DP-28 (which is already in the game) or possibly the SG-43.
Degtyaryov DT-29
Soviet T-34/85 tanks are armed with Degtyaryov DT machine guns.
M116 75 mm Pack Howitzer
American LVT(A)-4 amphibious vehicles are equipped with M116 75 mm Pack Howitzers in Mount M7s.
MG 34 Panzerlauf
German tanks have mounted MG 34 Panzerlauf.
MG 42
The MG 42 is mounted on German Sd.Kfz. 251 armored personnel carriers, Panzer IV Ausf. J, and King Tiger tanks.
Nudelman-Suranov NS-37
Two 37 mm Nudelman-Suranov NS-37 aircraft autocannons are mounted under the Sturmovik's wings.
Oerlikon 20mm Cannon
In "Black Cats", the player's Catalina is armed with twin Oerlikon 20mm Cannons under the bow turret. This is not part of any standard Catalina fit, but was reported as a field modification to "Black Cat" Catalinas in the Pacific; however, it required the removal of the twin M1919s in the bow turret, which are still present on the game's Catalina.
Type 92 Heavy Machine Gun
The Type 92 heavy machine gun is the main Japanese heavy machine gun and is found in every mission of the American campaign. In "Black Cats" Type 92 HMGs are mounted on Type T-25 MTBs.
Type 97 Aircraft Machine Gun
Japanese Mitsubishi A6M "Zero"s are armed with Type 97 aircraft machine guns.
Type 97 light machine gun
The Type 97 light machine gun is mounted on Japanese Type 97 ShinHōtō Chi-Ha medium tanks.
Type 99 20mm Cannon
Type 99 cannons are mounted on the A6M Zeros. Several M6A Seiran floatplanes on the Sub Pens map also feature a pair of Type 99s in the wings. Designed to be operated from the massive I-400-class aircraft carrier submarines (I-400 serves as the centerpiece of the map, with one of her sister subs also present), the real M6A did not actually feature offensive guns, but the in-game model is simply the game's Zero model with the nose/engine swapped for that of the Seiran, thus sharing its wing-mounted cannons.
Others
8.8 cm FlaK 37
8.8 cm FlaK 37 AA-Guns, which the same models as in Call of Duty 3, are seen in the Russian campaign missions. Notably, during the "Heart of the Reich" mission where German soldiers defend the Reichstag-Building with various FlaKs. Unlike the following PaK 43, the FlaK's 88×571mmR shells are not modeled; instead, the Germans insert some sandbags.
8.8 cm Pak 43/41
At the beginning of the mission "Heart of the Reich" Soviet soldiers fire two 8.8 cm Pak 43/41s at the Reichstag building. Unfortunately, the gun breech on the model is static and there is no model for the round they are inserting, leading to the disagreeable impression that the player has encountered a group of elite Soviet combat mimes.
203 mm howitzer M1931 (B-4)
Archive footage in the game shows several of these 18-ton 203 mm howitzer M1931 (B-4) during the intro sequence of the game and introduction to the Soviet campaign's Berlin levels; they are seen being used in the direct fire role, shooting down streets with their barrels level. They do not appear during gameplay.
Bofors 40mm
Some Bofors 40mm AA guns are seen on the map "Battery".
Thompson M1928A1
A M1928A1 Thompson fitted with a straight foregrip and a 30-round stick magazine appears in the hands of the American soldier prominently featured on the box art for the game, although it does not appear in the game itself.
Type 1 47mm Anti-Tank Gun
Japanese soldiers use several Type 1 47mm Anti-Tank Guns in the single-player campaign missions "Hard Landing" and "Relentless". Two Type 1s are also seen on the multiplayer map "Banzai". It is also the main gun of the Type 97 Shinhōtō Chi-Ha medium tanks.
As a note of trivia, these guns were used in the 1936-1939 The Spanish Civil War mod for Call of Duty 2 as usable AT guns.
A Type 3 200mm naval gun must be destroyed in the single-player mission "Relentless". The naval gun is also seen on the multiplayer map "Cliffside".
Type 96 AT / AA Gun
Japanese Type 96 25 mm AT/AA Guns in triple mountings, referred to as Triple 25 by the game, can be seen in several of the Pacific levels and commandeered by the player sometimes; per series traditions for large crew-served weapons, the gun has infinite ammunition (rather than 15-round magazines for each gun) and the player character is able to substitute for a nine-man crew by themselves.
Type 97 81-mm Infantry Mortar
The Type 97 Mortar is used by Japanese soldiers in the missions "Hard Landing", "Burn 'em out" and "Breaking Point". As mentioned earlier, when Miller picks up a Japanese mortar shell it turns into an American M34A1 shell.
