Call of Duty 4: Modern Warfare
Call of Duty 4: Modern Warfare (also known as CoD4:MW, CoD4, Modern Warfare 1, and MW1) is the fourth main installment of the Call of Duty series, and first installment of the Modern Warfare trilogy, officially released on November 5, 2007 in North-America for the PC, PS3 and Xbox 360, developed by Infinity Ward and published by Activision. This is the first game in the series to be set in modern time, taking place in the year 2011 during a fictional conflict between the United States, United Kingdom, and Russia against Russian Ultranationalist Rebels and an unnamed Middle-Eastern country (which happens to be where Saudi Arabia is), their forces simply known as "OpFor." The player takes the roles of Sergeant "Soap" MacTavish, a marksman and demolition expert of the British SAS, and Sergeant Paul Jackson, a US Marine of the 1st Reconnaissance Battalion.
A remastered version titled Call of Duty: Modern Warfare Remastered was released on November 4, 2016 as a bonus alongside the deluxe editions of Call of Duty: Infinite Warfare. On December 13th, 2016, Supply Drops and various kinds of micro-DLC items were added to the Multiplayer. Among them, "Weapon Kits" were introduced, which can alter a weapon's appearance with a new set of base textures or a completely new model.
Warning: Major plot spoilers in some of the weapon descriptions.
The following weapons appear in the video game Call of Duty 4: Modern Warfare:
The Beretta 92SB, incorrectly appears in-game as the "M9", is the main sidearm of Sergeant Paul Jackson and many other Marines and enemies, though an M45 / MEU(SOC) would be more accurate to see in use by the Marines as they are part of the 1st Reconnaissance Battalion; this is somewhat fixed in the "Shock and Awe" level, where Jackson's secondary weapon is a Springfield Armory Loaded instead. In-game, the 92SB has the same damage figures as the USP and the 1911, but has the least effective range. This is offset with the highest magazine capacity (fifteen rounds of 9mm) and the lowest recoil, allowing quick follow up shots. It can be suppressed. Interestingly, the hammer stays in the half-cocked position at all times, despite the fact it should be fully cocked after the first shot. What appears to be a 92-series pistol can also be seen on the Porter Justice posters, a (fictional) movie that looks to be a standard over the top Asian action movie.
Beretta M9 (remastered version)
In Modern Warfare Remastered, the weapon is correctly modeled after a Beretta M9.
Heckler & Koch USP45
The H&K USP45 is the sidearm of "Soap" MacTavish and other SAS soldiers in the game, but it would be more accurate to see them using SIG-Sauer P226, SIG-Sauer P228 or Browning Hi-Power. It uses .45 ACP rounds in a 12-round magazine. Its recoil, capacity, and stopping power make this gun the most balanced in its class. The hammer stays down at all times, which is possible since some variations of the USP do have a DAO setup in reality.
It appears that at some stage in design this weapon was going to be a Heckler & Koch Mark 23 rather than a USP; it mounts the prototype Mark 23 LAM, and has a visible projecting barrel in both first and third person modes which would not be present on a standard USP45. Interestingly, the Modern Warfare 2 USP45 model also has the rear sights of a Mark 23 even though this version does not, most likely due to recycling parts of the scrapped Mark 23 model.
The "Competition" weapon kit gives the weapon a bright and glossy red slide and a slightly brighter frame, and the "Spec Ops" kit gives it a barrel weight similar to that of the USP Match.
IMI/Magnum Research Desert Eagle Mark XIX
The Desert Eagle, chambered for .50 Action Express in-game, is the most powerful pistol. It holds seven rounds in its magazine and has the worst recoil. The main villain Imran Zakhaev carries this pistol as his weapon of choice. In the opening credit sequence, Zakhaev gives it to Khaled Al-Asad to kill President Yasir Al-Fulani. The only opportunity to use a Desert Eagle in singleplayer is in the level "Crew Expendable," where an Ultranationalist attacks with two of them. One with a black slide and barrel can be seen in the SAS armory. This gun is one of six multiplayer weapons that can have a gold finish, though the Gold Desert Eagle is unlocked at level 55 rather than through challenges. The weapon's hammer never in the cocked position, which would be required to be able to fire this single-action pistol. The ammo name for the Desert Eagle in the game files is .357 Magnum, contradicting the in-game .50 AE model and magazine capacity.
The original game's Gold Desert Eagle has been replaced in the Remaster with the "Commander Desert Eagle," still featuring a gold frame and slide, but now with a silver hammer, safety, and barrel, along with a shiny gray grip. Unlike the default Desert Eagle, it cannot have any custom camouflages or kits applied. In addition, the Desert Eagle replaces the Glock pistol on the icons of the Overkill and Last Stand perks
Springfield Armory PX9109L
A version of the 1911 makes an appearance in-game as the "M1911 .45". The handgun it was modeled after can't be known for sure, but it is closest to a Springfield Armory PX9109L, more commonly known as the "Loaded" model. It has four aftermarket parts: a stainless barrel bushing, black guide rod, black guide rod plug, and brown Simonich Gunner grips. It also uses Wilson Combat 47D eight-round magazines, but they only hold seven in singleplayer for some reason. It is the sidearm of choice for Captain Price and Viktor Zakhaev. Price lends his PX9109L to Soap after their helicopter is shot down in an early level, uses it to execute a high value target around the middle of the game, and slides it to Soap on the bridge at the end of the game. Staff Sergeant Griggs carries a stainless version with black grips, and uses it while pulling Soap to cover on the bridge. The stainless version can also be seen in the SAS armory. It can be suppressed. The weapon's hammer is never in the cocked position, which would be required to be able to fire this single-action pistol; oddly it is always in the half-cocked position.
The "M1911" as it appears in the Remastered Version is now properly depicted with the hammer cocked.
The "Whiteout" weapon kit exclusive to the SMG category paints them in glossy white and black.
FN P90 TR
The FN P90 TR, a version of the P90 with three accessory rails, is a rarely seen weapon (it is occasionally used by some enemies). Its sole "special" appearance is in the 1996 mission "All Ghillied Up" with suppressor and red dot sight, and in this case it is anachronistic; while the original P90 was available during that time, the TR variant was introduced three years later. In "Heat" and the epilogue mission "Mile High Club" it is simply an unsuppressed P90 using open rail iron sights. All versions fire 5.7x28mm rounds from a fifty-round magazine. The P90 is modeled with relatively weak per-hit damage and mediocre accuracy, relying on a high rate of fire and large magazine capacity for its effectiveness. The weapon is easy to wield in multiplayer, so much so that it has been restricted in competitive play due to its "spray" advantage over other weapons. Despite however many additions, it always has an unused laser attached to the side rail and H&K Diopter sights if it does not have a special sight.
The Remastered P90 TR is once again equipped with HK diopter sights and the unusable LAM. A new addition, however, is the translucent depleting magazine.
Heckler & Koch MP5N
The H&K MP5N is often used by "Soap" MacTavish and some of the SAS soldiers, along with the Marines in Russia and Captain "Deadly" Pelayo after her AH-1W "Super Cobra" is shot down, and also by some enemies. The MP5 fires 9x19mm rounds from a thirty-round box magazine. Accurate and decently powerful, it is a popular all-around weapon in multiplayer.
Applying camouflages to the weapon will paint over the weapon's selector markings, but the "Whiteout" weapon kit keeps them intact.
Heckler & Koch MP5SD3
"Soap" MacTavish and other SAS soldiers wield H&K MP5SD3 in the prologue and epilogue levels. When a suppressor is attached to an MP5 in multiplayer, it becomes an MP5SD3 with a Navy trigger group.
IMI Mini Uzi
Many enemies use the Mini Uzi. Modeled with weaker damage, it fires 9mm rounds from a thirty-two-round magazine. The high rate of fire and bouncing recoil leave its accuracy poor for all but the shortest ranges. Viktor Zakhaev carries one while escorting Al-Fulani to his execution, and while running from Soap, Gaz and Griggs. It is incorrectly shown firing from a closed bolt. This gun is one of six weapons in multiplayer that can have a gold finish.
Skorpion SA Vz. 61
Some enemies use the SA Vz.61 Skorpion. The side of the weapon reads "Zastava" and "Yugoslavia", despite being modeled after the original Czech Vz. 61 Skorpion and not the Vz. 61 E / M84 variant that would have a black pistol grip. Its high short-range damage, lack of recoil, and extreme rate of fire make it effective up close, balanced by a slow reload, low capacity (twenty .32 ACP rounds), and weak long-range damage. The weapon also has very little muzzle climb. Due to an early bug in multiplayer, where its damage did not decrease when silenced, the weapon has been banned from all major competitive leagues. The ban is likely for its ability to cause fifty damage at close range (half the regular health, 1/4th of the damage in Old School, and kills in one shot on Hardcore).
Benelli M4 Super 90
The Benelli M4 Super 90 appears as the "M1014." It has a higher rate of fire than the W1200, but a lower magazine capacity (in multiplayer) and, like the W1200, a slow reload time. It is used by some Marines and by Soap MacTavish in "Safehouse." The player never cocks the weapon on an empty reload, which would mean that a round isn't chambered and the gun couldn't fire. This gun is one of six weapons in multiplayer that can have a gold finish. In multiplayer the weapon holds four rounds but in singleplayer it holds seven rounds. This was also the only semi-automatic weapon, prior to a post-release patch, and in the remaster, to not have a ridiculous maximum rate of fire, as it's capped at 300 rounds a minute, as opposed to the 1200 RPM exhibited by the other semi-auto weapons. Said patch dropped the max ROF for the G3 and M14 down to 444 RPM due to these two weapons being ripe for exploit with modded controllers (or, on PC, the classic trick of binding "fire" to the mouse scroll wheel).
The Winchester 1200 appears as the "W1200" and is used by some of the Marines and many enemies throughout the game. Gaz pulls out a Model 1200 in "Crew Expendable." Lieutenant Vasquez carries one without the stock on his back, although he never uses it. It is powerful at close range, but is slow to reload and cannot even hit anything past ten meters. Marine use in-game can be considered erroneous, as the US Marine Corps use the Mossberg 590/590A1.
Assault Rifles & Battle Rifles
Most enemies and incorrectly Russian soldiers use the AK-47 instead of the AK-74M. It is also hybrid, featuring the early stamped receiver of a Type I AK-47, but the ribbed top cover from the later AKM. It fires 7.62x39mm rounds from a thirty-round magazine. Some of them have GP-30 40mm muzzle-loaded grenade launchers mounted on them. They feature a similar detonation safety as the M203 rounds, which is supposed to deter close-range use, but instead encourages it due to its lethal impact damage. It is powerful, relatively accurate, and the equivalent to the M16 rifle. The AK-47 has become an established favorite online, and especially in the competitive leagues, for many of the same reasons it has in the real world: it is powerful and flexible, offering dependable performance in nearly every situation. This gun is one of six weapons in multiplayer that can have a gold finish, this one most likely inspired by Saddam Hussein's gold-plated AK-47.
AKM (remastered version)
In Modern Warfare Remastered, the AK-47's weapon model has been changed to that of an AKM, as indicated by the stamped receiver, the sloped flash hider and the straight stock. An interesting attention to detail is the Cyrillic select fire markings "АВ" meaning "Автоматический" (Auto) and "ОД" meaning "Одиночный" (Single) which indicates Russian manufacture.
A mix-and-match of different Kalashnikovs appears in the game as a submachine gun under the name "AK-74u." While it handles like the other SMGs and its damage is modeled equivalent to the H&K MP5, the AK-74u penetrates walls and other cover like the other assault rifles, a trait it does not share with the other SMGs, though in return its sights also have more pronounced idle sway like an assault rifle. With decent power and accuracy, the AK-74u is an effective close- and medium-range weapon. In the campaign, it is mostly seen in the hands of Al-Asad's Middle East forces, and has a slower rate of fire than in multiplayer. One with a GP-30 is seen in the S.A.S. armory. It is modeled on the JG "AK Beta-F" airsoft rifle, which is an AKS-47 with a very short front end, an AKS-74U gas block/front sight, flash hider, and rear sight, and black polymer furniture with an RIS rail on the handguard. The version in-game has bakelite magazines, which led to some to believe it actually was a 74; the curve of the magazine and grooves on the magwell give away that it is based on a 47.
AKS-74U (remastered version)
In Modern Warfare Remastered, the weapon is modeled after an actual AKS-74U, but it is still has the original model's underfolding stock and black furniture. With the "Whiteout" weapon kit equipped in Multiplayer, the magazine is re-textured to look like a Magpul PMAG, with a black finish and a similar textured grip pattern. The key distinguishing difference is that the Soviet-style mag is pinched for the length of the projectile at the front, where a 5.45 PMAG has a uniform body thickness. Like the AKM, the AKS-74U also has Cyrillic select fire markings "AB" and "OД".
The civilian Colt AR-15A3 (distinguishable by its 16 inch non-stepped heavy barrel) is one of the main assault rifles featured in the game. The AR-15A3 (a semi-automatic only weapon) is referred to as an "M4A1" (a full-auto firing weapon) in singleplayer, but as an "M4 Carbine" (a three-round burst firing weapon) in multiplayer, and while it actually fires full-auto in-game, its fire selector switch is always set to semi-auto. The weapon features a Colt Canada C8 four-position collapsible stock, an M16A1 pistol grip and M16A1 flash hider, a KAC RIS handguard, and lacks a bayonet lug. It also has KAC rail covers on whatever rails are not in use (meaning always one on the right side), but they are only visible from a third-person view, and is equpped with a KAC foregrip as standard, but it is not visible in third person. If selected, the AR-15A3 can use an M203 grenade launcher; the third-person model of the launcher is oddly scaled down to about half the proper size, though the first-person model is scaled correctly. If optics are attached, the front sight/gas block is removed to provide a clearer sight picture, however this raises the same issue as the M16A4 above. Attachments available for the AR-15A3 in the multiplayer are: a Sightmark Sure Shot reflex sight, a Trijicon 4x32 ACOG, an M203 grenade launcher, or a suppressor. As expected, the Sure Shot and ACOG replace the carrying handle, the M203 replaces the KAC foregrip, and the Suppressor replaces the M16A1 flash hider. In singleplayer it appears in one of four specialized versons. There is a fifth, unused version called "M4 SOPMOD," that has the same attachments as the weapon of the same name in the actual game, except having iron sights. It can be seen in the SAS armory and can be acquired through the "Give All" cheat in the developer's console on the PC version while on the level "All In."
M4A1 (remastered version)
In Modern Warfare Remastered, the weapon is correctly modeled after an M4A1.
Heckler & Koch G36C
The H&K G36C is the first weapon the player get to use in the campaign. It is Gaz's signature weapon, and also used by other SAS soldiers, the Russian loyalists in the mission "Safehouse" and by many enemies late in the game. It anachronistically appears in both missions set in 1996; while the production of the original G36 began during that time, the G36C itself was not introduced until 2001. It is always equipped with a Tasco red dot scope in single-player. It has slightly heavier recoil than the Colt AR-15A3, but a higher rate of fire and much less sight sway. It is modeled with equal damage to the AR-15A3, reflecting its intermediate status as a carbine. It is incorrectly depicted with a magazine that is released by flicking the weapon downwards akin to an AR magazine; G36 magazines are removed by actuating the paddle forward of the trigger guard, similar to the AK-47. It is clearly missing the front sight and because of how low the red dot sits, you should be able to see the rear sight; the Remastered Edition corrects this by putting the red dot on a riser, but still removes the front sight.
Heckler & Koch HK91A3
The Heckler & Koch HK91A3, noted by lack of paddle magazine-release, collapsible stock, and two position fire selector (which is always set to safe, even with the animation for picking one up off the ground showing the player release the safety with his left hand), incorrectly designated as a "G3" in-game, is a common battle rifle used by the enemy factions. While firing on full-auto in single-player, in multiplayer it is restricted to semi-auto, but with a greatly increased maximum rate of fire (1200 RPM vs 600 RPM). The HK91A3 fires 7.62x51mm NATO from a twenty-round magazine. In the game, the base damage from this weapon is inaccurately equivalent to both the AK-47 and M16A4, though it seems to have better damage at range. The M14, which fires the same ammunition and is in the same class, is accurately modeled as more powerful than rifles firing intermediate cartridges such as the 5.56x45mm NATO or the 7.62x39mm Soviet. The in-game weapon accurately reflects the high accuracy of the G3 however the amount of recoil is inaccurately portrayed as being very low when firing.
Whereas most of the other weapons were replaced with the proper models they were named after for Remastered, the HK91A3 has made it into the new version with no significant modifications to turn it into any version of the Heckler & Koch G3. Nevertheless, the "Battleworm" weapon kit gives it an early G3 wooden buttstock and a CETME Model C handguard.
The M14 with a shortened barrel appears exclusively in multiplayer with a black stock, silver Knight's Armaments RAS, a silver RAS scope mount, and black rail covers on the side rails. It fires 7.62x51mm from a twenty-round magazine, like the G3, but unlike the G3 is accurately portrayed as being significantly more powerful than the other assault rifles, and has a hefty recoil befitting the powerful cartridge. Like the G3, the semi-auto sniper rifles and pistols, its maximum rate of fire is a ridiculous figure of 1200 RPM. The bolt does not lock open upon emptying the weapon.
It should be noted that the weapon lacks the bayonet lug under the front sight, and the third-person model also lacks the fire-control lever, making it resemble the Springfield Armory M1A civilian version.
In Modern Warfare Remastered, the weapon has the bayonet lug and correctly has the fire selector in third-person. The optic mount is now only present with an optic. An M14 with a torn-up wooden stock is present in the Multiplayer as part of the "Battleworn" weapon kit. Like in the original game, the bolt does not lock back upon being emptied.
The M16A4 is one of the available assault rifles in the game, used by many of the U.S. Recon Marines. Lt. Vasquez carries an M16A4/M203 combo as his weapon of choice. In-game, the M16A4 is attributed with almost the same damage as the AK-47 and the "G3", despite the real weapon having far from the energy of either. In single-player, the M16A4 incorrectly fires fully automatic (like the M16A3), unlike in multiplayer, in which it is depicted accurately, firing in three-round burst mode. This makes an on-target salvo from the M16A4 very effective, but also makes misses much more costly, especially in close-quarters when pitted against full-auto weapons. Optics mounted on the M16A4 remove the front sight and gas block, which would render the gun unable to cycle automatically after the first shot, and the shooter would have to manually rack the bolt to load the next round into the chamber, effectively making the gun bolt-action. In addition, when not equipped with an M203, the third-person model appears with the standard M16A2-style handguard instead of the KAC M5 railed handguard with covers that appears in first-person. When equipped with a M203, the old dedicated M203 heat shield is used instead of the KAC railed handguard, giving the weapon the appearance of an M16A2. The weapon also appears to be using an M16A1 flash hider and it has an M16A1 carrying handle in third-person (if optics are not equipped). In the campaign, it is portrayed to fire in full auto and only burst in multiplayer. The same still applies to the Remastered edition.
The M16A4 in Modern Warfare Remastered comes standard with 2 less rail covers on the 3 and 9 o'clock rails, the fire selector properly set to "Burst", and a slightly shorter rear sight (or slightly taller carry handle). The old heatshield is retained when the M203 is equipped, however the model is the same rail-mounted M203 as used on the rest of the assault rifles. This can clearly be seen with the "Battleworn" weapon kit equipped. Like the M4A1, the front sight is replaced with a low-profile gas block when using optics.
The Sturmgewehr 44 only appears in multiplayer, referred to as the "MP44" (as it was in earlier Call of Duty games). It is powerful with no sway whatsoever while aiming (which it shares with the burst firing M16 and the 2 semi-auto rifles in its class), but has high recoil and low accuracy during sustained fire. It appears as a nod to the previous Call of Duty games, and is also the same model of the STG-44 from Call of Duty 2. It is incompatible with the attachments available for other assault rifles (another throwback to the earlier titles, where weapons could not be modified beyond adding scopes to bolt-action and semi-auto rifles), but it can still accept camouflage.
A programming bug makes all weapon scopes use the "scope_overlay_m40a3" image (the M40A3 reticle) rather than their own; the game files contain seven other reticle models, including two separate ones for the M21. Unfortunately, this error was not corrected in the remastered edition.
The Barrett M82 appears once in the single player mission "One Shot, One Kill" as a stationary weapon (with variable zoom and unlimited ammunition), which Lieutenant Price uses to take the titular shot. It is an unlockable weapon in multiplayer, where it is the most powerful rifle available. Much is made of the supposedly realistic ballistics in "One Shot, One Kill;" a long list of factors affecting the shot is given, but the only two actually accounted for are bullet drop due to range and deflection due to wind; the weapon does fire modelled projectiles in this sequence rather than using hitscans. The actual purpose of the long-range shot is rather less than realistic; the first shot the player fires which intersects Zakhaev's hitbox will always curve and hit his arm no matter where it was aimed, while all subsequent shots, regardless of aim, will curve away and miss him. This odd "force field" is later seen again when the player is tasked with firing RPGs at a Mi-24 Hind with Zakhaev in it, and they will always curve away from it to miss.
In Modern Warfare Remastered's multiplayer, the "Assassin" weapon kit places the M82A1 into a fictional chassis that features a full length RIS rail, giving it some resemblance to the Barrett M107.
All enemy snipers use the Dragunov SVD. Its random recoil makes it difficult to use. This gun is one of the six weapons in multiplayer that can have a gold finish.
The M21 Sniper Rifle appears in this game in both suppressed and unsuppressed versions. Both SAS and Marine snipers use it. It is a top of the line M14 rifle fitted with a scope (and a silver RAS mount for that scope), silver Knight's Armaments RAS, black rail covers on the side rails, and a smaller ten-round magazine. It is fitted with a "Leupold Mark 4 6.5-20x50mm ER/T" scope. The rear end seems to be enlarged in-game, most likely something to do with the scoping-in animations working properly, and the whole thing is also mirrored. Similarly to the M14, the third-person model lacks the fire selector (though it actually has a bayonet lug), making it resemble a scoped Springfield Armory M1A.
The third-person model in Modern Warfare Remastered now correctly displays the fire selector in third-person.
The M40A3 is only usable in multiplayer, most likely due to a USMC sniper mission being cut from singleplayer, and is similar in performance to the R700. It is more accurate and nearly as powerful. It holds five rounds of 7.62x51mm NATO in an integral box-magazine and has to be loaded one bullet at a time. One with a black stock can be seen in the SAS armory. In multiplayer, it is the most popular sniper rifle, due to an oversight that increases its base damage when attached with an ACOG scope.
In Modern Warfare Remastered's multiplayer, the "Assassin" weapon kit places the M40A3 into a custom chassis similar in style to the Cadex Defence Strike Dual rifle chassis.
Remington Model 700P
The Remington Model 700P appears as the "R700." It is very powerful but has the shakiest scope view, heavy recoil, and frequently misses where it as actually shooting. It only appears once in single player, used by "Soap" MacTavish at the beginning of "Sins of the Father." It holds four rounds of 7.62x51mm NATO in an integral box magazine and has to be loaded one bullet at a time. The caliber is determined based on the size of the bolt and breech. Though the M40A3 is very much the same weapon, they have slightly different attributes in-game.
Similarly to the M40A3, the "Assassin" weapon kit places the Remington 700 into a chassis comparable to the Cadex Defence Strike Dual rifle chassis.
The RPD light machine gun is the enemy's support weapon. It fires 7.62x39mm rounds from a hundred-round belt box. Mounted RPDs are usable in "Shock and Awe" and "Safehouse." It is the most accurate machine gun when aiming down the sight (even without an ACOG or red dot sight), but has poor hip-fire accuracy and takes almost ten seconds to reload. It is incorrectly seen in the hands of Russian troops in 1996 and 2011, who have actually switched to the PKM decades before.
An excellent attention to detail in the remastered version is the ammunition belt of the RPD and other machine guns will correctly correspond to the number of remaining rounds. A break from most FPS games where the ammo belt will always be full and then either suddenly disappear when the weapon is empty, or simply never run out as the player character replaces it just to play fair.
The M60E3 appears, incorrectly referred to as the M60E4, which has a much shorter barrel and larger handguard than the E3. It only appears once in single player, at the end of the game, used by one of the soldiers accompanying Zakhaev. It has a higher rate of fire in single player than in multiplayer. It fires 7.62x51mm rounds from a hundred-round belt box. It is the strongest machine gun, but it suffers from damage drop-off at long ranges and also takes almost ten seconds to reload. This gun is one of the six weapons in multiplayer that can have a gold finish.
The M249E2 appears in the game, used by the US Marines (most notably Staff Sergeant Griggs) and members of the SAS (standing in for the FN Minimi). The M249 loads a hundred-round belt of 5.56x45mm. Its rate of fire is greater than the RPD or M60, but it does less damage per bullet. Its recoil is greater in single player than in multiplayer. It can mount a grip, ACOG scope, or red dot sight in multiplayer.
GP-30 Grenade Launcher
The GP-30 grenade launcher is seen on the AK-47 only and is mislabelled as a GP-25; the quadrant sight for the launcher is mounted on the right-hand side of the weapon, while the GP-25's would be mounted on the left. One is also seen mounted on an "AK-74u" in the SAS armory. While the grenades do the same damage as the M203's, the GP-30 has a much faster draw time, but slightly slower reload.
M203 Grenade Launcher (Airsoft)
An airsoft version of the M203 grenade launcher, distinguishable by its distinctive RIS mount, appears as the standard grenade launcher for every weapon except the AK-47. Since a direct hit with even an unarmed shot is an instant kill, the M203 has earned the nickname "Noob Tube." Equipping an M203 prevents that class from using Perk 1. When mounted on the AR-15A3 and M16A4, the third-person model's lower receiver height is stretched and gives it a somewhat silly appearance, and the M203 itself is too small in scale in third-person, by about half. It also lacks a trigger guard.
The FGM-148 Javelin anti-tank guided missile launcher is used in the single-player missions "War Pig" and "Heat" to destroy enemy tanks; it is single-shot and requires a lock-on to fire and can only lock onto (and thus fire at) those tanks; in-game the entire unit, launch tube and command launch unit combined, is discarded after firing for the user to pull a new fully-formed one out of nowhere. A direct-attack mode Javelin can be found near the missile silos on "All In." In both modes the Javelin is shown firing at impossibly short range: it climbs practically vertically rather than at a steep diagonal, and should not be able to hit targets closer than 160m in indirect mode or 65m in direct mode.
FIM-92 Stingers appear in enemy weapons caches in "Hunted" and "All Ghillied Up," though using one in the latter mission runs counter to its stealth aspect. They are used against enemy helicopters. As to why NATO MANPADS happen to be conveniently lying around Ukraine and Russia, just waiting to be used against Mi-8s and Mi-24s is another mystery in entirety.
While the Stinger has yet to acquire the later-series ability to generate digital targeting boxes with its iron sights, it is still very inaccurately portrayed: the player character does not insert a BCU into the weapon before firing (something which is needed to give a 45-second window when the weapon can actually be fired) meaning it is apparently powered by some kind of integral perpetual battery and thermodynamics-reversing unit, and the missile is shown as seeking straight out of the tube rather than flying in a straight line for 660 feet before it can track anything.
Some Marine NPCs have an M136 AT4 strapped to their packs. It was cut as a usable weapon from the final game, but is accessible in "Shock and Awe" through the "Give All" cheat.
The RPG-7 is commonly seen in enemy hands and can be used by the player in-game. In multiplayer it is a good weapon against helicopters but has abysmal accuracy at long range due to the round spiraling unpredictably, probably because it doesn't deploy its stabilizing fins after launch.
Amusingly, after the August 8, 2017 update, the player is able to use an RPG-7's warhead as a melee weapon called "Danger Close". One of the animations involves the player character juggling with three warheads and then throwing away two of them, resulting in two explosions being heard.
The RPG-26 is seen strapped to the packs of several Ultranationalists, with textures burgled from the AT4 model rather haphazardly applied to it.
M67 Hand Grenade
The frag grenades seen in-game are M67 hand grenades. They bounce much greater than their real-world counterparts and inflict damage solely through concussive force. In singleplayer, the player begins each level with four grenades. In multiplayer, everyone has one grenade and can choose a perk to carry three.
M83 Smoke Grenade
M83 smoke grenades only appear in single player in "All In" and "Heat." Smoke grenades in multiplayer cannot be used in conjunction with the "Special Grenades x3" perk.
M18 (remastered version)
In Modern Warfare Remastered, the M83 is replaced with the M18 smoke grenade.
M84 Stun Grenade
M84 stun grenades appear as both the stun and flash bang grenades, oddly having its uses split between the two. In multiplayer, a player can select either a flashbang or a stun grenade as special grenades, and carry three with a perk.
M18A1 Claymore Mine
The M18A1 Claymore Mine appears in the single-player levels "Blackout" and "One Shot, One Kill." They are also available in multiplayer, where a player can equip two Claymores as a perk.
C4 packs are issued in certain singleplayer missions and available in multiplayer by equipping the C4 perk.
The M240C can be seen mounted coaxially on the M1A1HA Abrams.
The M240D is seen mounted on the loader's hatch of the M1A1HA Abrams tanks in several missions.
The Browning M2HB is seen mounted on the commander's hatch of M1A1HA Abrams tanks in several missions. It is not supposed to be available to the player at any point, but a usable M2HB on a stand is outside the map in "Charlie Don't Surf," accessible by exploiting a bug.
General Dynamics GAU-17/A
The General Dynamics GAU-17/A appears as a usable stationary weapon mounted on a downed helicopter in the mission "Heat" and is used by a door gunner on a Black Hawk in both "Crew Expendable" and "The Sins of the Father." That the M134 in "Heat" works at all is miraculous: an aircraft-mounted M134 is attached to the craft's electrical system, since it needs external power to function. This had been proven fairly recently in 2002 during the Battle of Takur Ghar / Roberts Ridge in Afghanistan, when the downed MH-47 Chinook Razor 03 could not return fire with its miniguns due to damaged electrical systems. Unlike later Modern Warfare games it does not have a slotted flash hider, but does have the additional barrel discs of a GAU-17 rather than the single clamp of a Dillon Aero model.
Mk. 19 Automatic Grenade Launcher
The Mk 19 grenade launcher appears as a usable weapon mounted on a CH-46 Sea Knight helicopter in the mission "Shock and Awe," its use governed by a heat gauge.
M242 Bushmaster Chaingun
An M242 Bushmaster Chaingun can be spotted mounted on an M2A2 Bradley IFV in the multiplayer map "Ambush".
Opfor and Ultranationalist BMP-2 infantry fighting vehicles are modeled with the coaxial PKTM machine gun, although they only appear to use the 2A42 autocannon.
Kurzer 8 cm Granatwerfer 42
The Shipunov 2A42 is mounted on Mi-28N Havoc helicopters, used by both Russian loyalist forces by the Ultranationalist party during the missions "All Ghilled Up" and "One Shot, One Kill." The latter use is anachronistic, as the mission takes place in the year 1996 and the all-weather Mi-28N (distinguished by the mast-mounted radar) was not operational until 2006; the first prototype didn't even fly until November of 1996. BMP-2 IFVs also use the Shipunov 2A42.
General Dynamics M197 Vulcan
The M197 Vulcan is mounted on AH-1W Super Cobras used by the US Marines. In multiplayer, the Super Cobra is the support helicopter for both US Marines and SAS, awarded for 7 kills in a row.
General Electric GAU-12/U
The Bofors 40mm is mounted on the AC-130U Spooky in the mission "Death From Above," alongside the GAU-12/U and M102 Howitzer.
M102 105mm Howitzer
The M102 105mm howitzer is mounted on the AC-130U Spooky in the mission "Death From Above," alongside the GAU-12/U and 40mm Bofors.
The Glock 17's silhouette appears in the "Last Stand" and "Overkill" perk symbols.
In the intro for "The Coup", soldiers carrying Al-fulani are carrying AK-74s, which switch to AK-47s (AKMs in Modern Warfare Remastered) in-game.
In some levels, "Soap" MacTavish can find posters on the walls with the details of an AKM assault rifle.
In a nod to the previous Call of Duty installments, WWII-era posters of a woman holding an M1928A1 Thompson can be found in various buildings, one being the SAS armory.
Many statues throughout the campaign and multiplayer levels are of Russian soldiers holding PPSh-41. No usable PPSh-41 appears in-game.
RGD-5 hand grenade
The RGD-5 hand grenade is added to the models of some enemies in Modern Warfare Remastered. It is unusable in gameplay.
Modern Warfare Remastered exclusive weapons
A Luger P08 with some minor cosmetic alterations has been added to Modern Warfare Remastered via an update on August 8, 2017; it is referred to as the "BR9". Despite the real Luger using 9x19mm or 7.65x21mm ammunition, the in-game weapon is attributed with the same high damage as the Desert Eagle and the Taurus Model 689 (as well as a recoil profile similar to that of the Desert Eagle), though with faster damage drop-off at ranges.
The "Prokolot" (which means pierce in Russian) is a three-round burst pistol that was added to Modern Warfare Remastered, via an update on May 2, 2017. It is a hybrid weapon featuring parts of the Arsenal Strike One and the Arsenal USA Stryk-B, though its length is intermediate between the two. It also seems to have a custom Glock trigger. The grip is also similar in appearance to the MP-443 Grach.
Taurus Model 689
A Taurus Model 689 with rubber grips has been added to Modern Warfare Remastered via an update on February 7, 2017. Like the Colt Anaconda from Modern Warfare 2 and Modern Warfare 3, it is referred to as ".44 Magnum", although this time it is wrong since the Model 689 isn't available in this caliber. It also inappropriately has the ability to equip a suppressor, and shares ammunition with the Desert Eagle, which is incorrect since the Desert Eagle in-game is modeled after the .50 AE version.
The "Fang 45" is a fictional AR15-style pistol caliber carbine chambered in .45 ACP that was added to Modern Warfare Remastered via an update on May 2, 2017. It appears to be a mixture of an LWRC SMG-45 and a Patriot Ordnance Factory PSG.
The MAC-10 has been added to Modern Warfare Remastered via an update on March 14, 2017. Despite the 30-round capacity (normally used for the .45 ACP version), the weapon is implied to be chambered in 9x19mm, as it shares ammunition with the M9, MP5 and Mini Uzi. During empty reloads, the open bolt is pulled back before changing the magazine. On a side note and interesting bit of trivia, the MAC-10 was originally featured in the Nintendo DS version of Call of Duty 4.
The "PK-PSD9" is a three-round burst submachine gun that was added to Modern Warfare Remastered via an update on August 8, 2017. It consists of the aforementioned "Prokolot" fitted with an extended magazine, and placed into a carbine conversion kit that includes a spare mag holder (similarly to the CAA Tactical RONI, but at the front instead of the rear). The muzzle brake seems to be inspired by the RONI Civilian Pistol Carbine Conversion C-G2.
A heavily embellished Saiga 12K converted to full-auto has been added to Modern Warfare Remastered via an update on February 7, 2017. It is referred to as "Kamchatka-12" in-game, and has a stock similar to the SLR-95 Thumbhole stock. Kamchatka is the name of an eastern peninsula region in Russia.
Dual-wielded Sears Ranger double barreled shotguns were added to Modern Warfare Remastered via an update on June 27, 2017. Prior to this, a sawed-off double barreled shotgun could be seen holstered on the backpack of the depot supply drop contact (who is an ex-SAS captain) in Remastered.
AAC Honey Badger
The "Lynx CQ300" is a new assault rifle that was added on the August 8, 2017 update. It resembles the AAC Honey Badger that was featured in Call of Duty: Ghosts, and it also reuses the same reload animation. The Honey Badger's integrated suppressor is replaced with a custom muzzle brake, and it also has a grip stop resembling the Lanco Tactical Grip Stop 2.
The "BOS14" is an assault rifle that was added to Modern Warfare Remastered via an update on May 2, 2017. It is primarily based on the SCAR 17 Ultralight, a bullpup conversion of the SCAR-H, though the BOS14 has a 5.56x45mm magazine, essentially making its basis a bullpup version of the SCAR-L.
The "XM-LAR" is a FAL-type fully-automatic rifle that was added to Modern Warfare Remastered via an update on February 7, 2017. It consists of an FN LAR lower receiver and rear sight, a railed diagonal-sided upper typical of modern FAL variants like the DSA FALs, IMBEL IA2 and SC-2010, and a DSA SA58 OSW handguard and charging handle, as well as a custom stock. It shares ammunition with the 7.62x39mm AKM, despite clearly having a 7.62x51mm 20-round magazine (holding 30 rounds in-game).
Cheyenne Tactical M-200 Intervention
The Cheyenne Tactical M-200 Intervention was added to Modern Warfare Remastered via an update on June 27, 2017, called the "S-Tac Aggressor". The weapon model is fitted with a handguard looking similar to that of the PGW LRT-3 sniper rifle.
The "D-25S" is a semi-automatic sniper rifle that has been added to Modern Warfare Remastered, via an update on March 14, 2017. It appears to consist of an F&D Defense FD308 upper receiver and a Heckler & Koch G28 lower receiver, as well as a Geissele Super Modular Rail HK style handguard and a stock very similar to the Magpul PRS. It shares ammunition with the 7.62x51mm rifles in-game, and it is referred to as "DMR-25" in the game files. "CAL .308" and "MADISON WI USA" can be seen written on the magazine well.
The PKM has been added to Modern Warfare Remastered via an update on March 14, 2017. It correctly feeds from the right side (unlike the PKP Pecheneg from Modern Warfare 3), but for some reason it shares ammo with the differently chambered M249 SAW.
