Arma 3, stylized as ARMA 3, Arma III, ArmA 3, or ArmA III, is a military-simulation video game developed and published by Bohemia Interactive Studio (BIS) exclusively for the PC. It is the third installment of the ArmA series, officially announced on May 19, 2011, and is built around the new Real Virtuality 4 engine owned by BIS. The playable alpha version of the game was made purchasable on the Steam store and BIS' page on March 5, 2013. The beta was released on June 25, and the full release was on September 13, 2013. New weapons and vehicles are added with each new part of the free-to-download campaign, split up into multiple chapters.
The storyline is set in 2035, when NATO influence is on the decline, while a new Eastern military alliance led by China and Iran called the Canton Protocol Strategic Alliance Treaty (CSAT) is on the rise. The setting are two islands located in the Aegean Sea, the 270km² Altis (based upon the 477km² Greek island, Lemnos) and the 20km² Stratis (based on the 43km² island of Agios Efstratios). The Republic of Altis and Stratis is in a state of civil strife following a military coup by the Altis Armed Forces (AAF), where a loyalist insurgency group known as the Freedom and Independence Army (FIA) wages a guerrilla war against the AAF. Following the signature of a ceasefire between the AAF and the FIA, the US Armed Forces is involved as NATO peacekeepers to oversee the ceasefire. However, the ceasefire breaks down, and the AAF allies with CSAT to suppress the FIA by full force, while restricting NATO to Stratis. Things go from bad to worse when the AAF declares war on NATO due to a muddied firing incident on Stratis, triggering an all-out war. The main protagonist of the campaign is Corporal Ben Kerry, an American NATO soldier stationed on Stratis, who needs to work with the enigmatic Captain Scott Miller and the FIA remnants to survive and turn the tide of the war.
ArmA 3 received multiple expansions and DLCs post-release, adding new weapons and equipment. The first major expansion, Apex, features a new 100km² Pacific setting, Tanoa, a new co-op story campaign, and a variety of new high- and low-tech weapons. After a natural disaster, Tanoa is left vulnerable to crime and disorder from a local paramilitary criminal group, the Syndikat. New armed factions added are the Chinese Pacific CSAT forces, special forces for both NATO and CSAT, the Combat Technology Research Group (CTRG) and Viper respectively, and the minor faction of the Tanoan Gendarmerie. The DLC campaign has players playing as CTRG Group 15 operators dismantling Syndikat influence on the islands and uncovering a CSAT conspiracy behind the scenes. It was released on 11 July 2016, after some time in public beta testing.
A second expansion called Contact was announced 23 May 2019. Like Apex it featured a new Poland-based map, Livonia, a new story campaign, and new units - this time the Livonian Defense Force and the Russian Spetsnaz.
ArmA 3 received four "Creator DLC" expansions, which are developed by external third party developers but published by Bohemia Interactive.
- Global Mobilization - Cold War Germany: Developed by Vertexmacht and released on April 29th, 2019. This DLC features a new German-based map, Weferlingen, and new Cold War era factions and equipment, including West Germany, East Germany, and Denmark.
- S.O.G. Prairie Fire: Developed by Savage Game Studios and released on May 6th, 2021. This DLC features a 300km2 Vietnam-based map, Cam Lao Nam, as well as Vietnam War-era equipment and factions such as the US Army, the Army of the Republic of Vietnam (ARVN), the Viet Cong and the North Vietnamese Army (NVA).
- CSLA Iron Curtain: Developed by CSLA Studio and released on June 16th, 2021. This DLC features a Central European map, Gabreta, set on the Czechoslovak-West German border during the Cold War in the 1980s.

- Western Sahara: Developed by Rotators Collective and released on November 18th, 2021. This DLC is set within a "canon-compatible" version of the Armaverse in year 2036, and features Sefrou-Ramal, a Sahara-based map set in the African country of Argana. Factions featured include US-led NATO forces in Argana, ION Services private military contractors, United Assistance Mission in Argana (UNA) peacekeepers, the Sefrawi Freedom and Independence Army, and indigenous Tura tribal fighters.
On this page, weapons marked with a (*) are DLC content (outside of the major DLCs, whose content are in separate sections), and their respective DLCs must be purchased in order to use them.
Faction name reference (for the purposes of this page):
- BLUFOR: NATO
- OPFOR/REDFOR: CSAT
- INDFOR/GREENFOR: AAF
The following weapons are featured in ArmA III:
The Walther P99 serves as the standard sidearm of NATO forces. Its in game designation is P07, and it's rechambered for 9x21mm. It appears in two variations in the game, the base game featuring it with a black slide and tan frame, while Apex adds a version with a green frame.
The MP-443 Grach appears as the CSAT's standard-issue sidearm under the fictional classification of Rook-40 (Rook being the translation of "Grach". Like the P99, it is rechambered to 9x21mm, and their magazines are interchangeable.
The ACP-C2 is the standard sidearm of the GREENFOR forces. It is a 1911 variant, based on a combination of a variety of models, namely the Kimber Custom Covert II, with the Kimber Desert Warrior and the Colt Rail Gun. It is chambered in .45 ACP and has a magazine capacity of nine.
The FN FNP-45 is BLUFOR's "heavy pistol". Heavy pistols are essentially similar to regular pistols in game, except they can mount certain optics on their top rail and have higher power per-shot in return for lesser ammo capacity. It was released as a free update on October 31st, 2013. In-game, it is known as the 4-five, and is chambered for .45 ACP, though it uses 11-round magazines rather than sharing the ACP C2's nine-rounders. Is also used by the LDF in the "Contact" expansion.
Chiappa Rhino 60DS
The Chiappa Rhino 60DS is CSAT's "heavy pistol", released alongside the FNP-45 as a free update on October 31st. As a revolver, it has an even smaller capacity than the FNP, and cannot accept a suppressor. In-game, it is named the Zubr (Russian for Bison), and is chambered in .45 ACP.
Taurus Judge (*)
Released on the 29th of May, 2014, the Taurus Judge is refurbished as the Starter Pistol for the Karts DLC. Instead of blanks, it fires flare shells, in either red or green colours, in burst of 3 per shell. The reload animation changes depending on the amount of rounds present before the reload, though for some reason the number of rounds present before reload is used for both the number of ejected rounds and the number of rounds in the new speedloader.
The TDI Vector is the BLUFOR SMG of choice. It is known as the Vermin SMG, and fires the .45 ACP cartridge, with a magazine capacity of 30.
CZ Scorpion Evo 3 A1
The CZ Scorpion Evo 3 A1 is the CSAT SMG of choice. It's known in game as the Sting, and uses 9x21mm ammo in curved 30 round magazines.
ST Kinetics CPW
The ST Kinetics CPW is the INDFOR SMG of choice, know in game as the PDW2000. It uses 9x21mm ammo, in either straight 30 round magazines or 16 round pistol magazines.
The ADR-97 is a family of 5.7mm submachine guns added in the Warlods Update on Dec. 3, 2018, based on the FN P90. The weapons originally came from an officially supported ArmA 3 mod called the ADR-97 Weapon Pack, created by ArmA 3 programmer Jakub Horyna in his spare time. Four variants of the ADR-97 are found: the base ADR-97 based on the PS90, the ADR-97C compact version based on the original P90, and railed versions of the two, ADR-97 TR and ADR-97C TR, based on the PS90 TR and the P90 TR respectively.
The rounds in the translucent magazine are fully animated, and deplete as the gun fires. The gun is used by the LDF in the "Contact" expansion.
The MX family of rifles is the standard-issue weapon for NATO forces. The MX series, designed by real-life CMMG, Inc., has design elements borrowed from the Remington ACR and Robinson Armament XCR. It fires caseless 6.5x39mm ammunition, though it is implied that it could could fire traditional cased ammunition due to the presence of an ejection port on the right-hand side of the weapon.
The MX comes in five variants:
- The standard MX rifle, equipped with a Magpul UBR stock.
- The MXC carbine with a shortened barrel and handguard, equipped with a Magpul CTR stock. Both the MX and the MXC are also equipped with the Magpul AFG2 Angled Foregrip with a flat "A1-style" surface.
- The MX 3GL grenadier variant with an underbarrel Metal Storm 3GL instead of a foregrip.
- The MX SW squad support weapon with extended lower handguard and barrel, Z-M LR 300 stock, vertical foregrip, an integrated bipod, and using thicker 100-round magazines.
- The MXM marksman rifle with the Magpul PRS stock, extended barrel, and vertical foregrip. Both the MX SW and MXM also feature simplified Picatinny rails on their handguards.
DIO KH2002 Sama
A fictional variant of the DIO KH2002 Sama, known in game as the Katiba, is the standard-issue service weapon of CSAT soldiers in the Mediterranean (which is composed of Iranian forces). Like the MX series, it fires caseless 6.5mm rounds, though their magazines are rather obviously not interchangeable. The carrying handle has been replaced with a lowered and railed one that highly resembles that of the G36C, with new irons integrated into it, and the original charging handle has been modified and extended to the left to fit this lowered carrying handle. The Katiba is available in a carbine variation with a short barrel and a grenadier version with an underbarrel EGLM.
FN F2000 Tactical
A fictional variant of the FN F2000 Tactical designated the Mk20 is the standard issue service weapon of the AAF. It features the Monolith Arms rail system and an unremovable foregrip, preventing it from using bipods. It is also available in a shorter-barreled version as the "Mk20C", and a version of the carbine with the FN GL-1 instead of the foregrip, called the "Mk20 EGLM". Like the real weapon, it fires 5.56x45mm NATO.
IMI Tavor TAR-21
The IMI Tavor TAR-21 is used by the FIA guerrillas. The in game designation for the full length variant is TRG-21, suffixed "EGLM" when equipped with the GL-1, while its carbine version (corresponding to the CTAR-21 variant in real life) is known as TRG-20. They're chambered in 5.56x45mm NATO.
Kel-Tec RFB Carbine
Kel-Tec RFB Carbines modified into a fictional amphibious weapon appears as the SDAR (Special Dual-medium Assault Rifle), and is used by all factions. It is chambered in 5.56x45mm NATO, and can use two types of magazines: 30-round STANAG magazines, and 20-round magazines with 5.56mm supercavitating ammunition, allowing it to fire underwater (visually, the weapon is always using straight 20-round magazines). Conceptually, the weapon is identical to the ADS Amphibious Rifle developed in Russia, with its name being almost a direct translation of ADS.
Oddly enough, its selector switch has only two positions marked; safe and fire, albeit the rifle's ability to fire in semi, three-round burst and full automatic modes. To compensate for its selectable settings, the switch will just stop halfway, at the 6 o'clock position, for burst fire.
Mk 14 Mod 0 EBR
The Mk 14 Mod 0 EBR is used by INDFOR soldiers in the Marksman role. It's known in-game as the Mk 18 ABR (Advanced Battle Rifle), and is chambered for 7.62x51mm NATO.
The CheyTac M200 is the anti-materiel rifle of the BLUFOR faction, and is labelled as the M320 LRR (Long Range Rifle) ingame. It is chambered in .408 CheyTac.
Gepard GM6 Lynx
The GM6 Lynx is the anti-materiel rifle of the CSAT faction. It's one of the few weapons in the entire game to have its real name, and its field manual entry also mentions its real manufacturer, Gepard. It was first demoed at the Gamescon conference, and was licenced from SERO Engineering Ltd., the designer of the weapon. It's chambered in 12.7x108mm.
The VS-121 was released on October 31st, 2013, and replaces the Mk14 EBR for CSAT's marksmen. In game, it's known as the Rahim, and is chambered for 7.62x54mm. It can fire in full-auto like the SVU-A.
Noreen "Bad News" (*)
Added as part of the Marksmen DLC on 8/4/15, the MAR-10 is heavily inspired by the Noreen "Bad News" rifle according to the devs. It uses custom stock, custom grip and custom handguard seemingly inspired by the War Sport LVOA handguard. It's chambered for .338 Lapua, and is tied to the NATO faction.
The side of the magazine well depicts a modified Bohemia Interactive logo and is marked "Bohemia Industries Firearms Division", a cheeky reference to the game's developers, Bohemia Interactive. The logo also appears on the Type 115 in the Apex DLC.
SIG-Sauer SIG556 DMR (*)
Added as part of the Marksmen DLC, the Mk-I EMR (Enhanced Marksman Rifle) is heavily inspired by the SIG556 DMR. It was rechambered in game for 7.62mm, with the developers giving the reasoning that 5.56mm would be too weak for ArmA 3's future. It fires in single or full auto, and is also tied to the NATO faction.
The weapon is marked "Mk-I EMR 7.62mm Bohemia Armory", another Easter Egg referring to the game's developers.
The first Marksmen rifle for the CSAT faction is pretty odd. It's known as the Cyrus. It's claimed by the developers to be inspired by the SVD and Saiga rifles, and seems to be primarily based on the SVDK. It's chambered for 9.3x64mm as a counterpart to NATO's .338 Lapua Magnum, and fires in single or full auto.
The side of the magazine well reads: "Cyrus 9.3x64 / Made in Chenarus", referencing Chenarus, the fictional country from ArmA 2.
The other CSAT faction Marksmen rifle is a very VSS-esque design, designated the ASP-1 Kir. Perhaps owing to the future setting, it's a very customized design. It is integrally suppressed, and chambered for the subsonic 12.7x54mm round, making it the least accurate and shortest-ranged rifle in the game, in return for incredible power within its short effective range. Its caliber suggests it to be an evolution of the VKS, which the developers mentioned was one inspiration/real life counterpart. Is also used by the Spetnatz in the "Contact" DLC.
A more retro design in these future days, the M14 battle rifle turns up almost totally un-modified as the Mk14. It's tied to the FIA faction, is chambered for 7.62mm, and fires in semi or full-auto.
A civilian variant with shorter 10 rounder mags, a wooden stock and in semi-auto only was added in the Contact DLC as the "Mk14 Classic" where it's commonly used by Livonian hunters.
KAC Stoner LMG
The KAC Stoner LMG, appearing as the Mk200, is the machine gun available to INDFOR in-game. It features a Magpul UBR stock and can be fitted with various accessories. It fires 6.5x39mm caseless ammunition. Is also used by LDF in the "Contact" DLC.
IMI Negev NG7
The IMI Negev NG7 is the CSAT medium machine gun, chambered in 7.62x51mm NATO, and appears as the Zafir. It is fitted with a variety of modern furniture, including a FAB Defense stock. The Field Manual says that the Zafir is mass-produced in China based on a copied Israeli design.
The first of two GPMGs added with the Marksmen DLC, the SPMG (Special Purpose Machine Gun) is a design inspired by the General Dynamics Lightweight Medium Machine Gun. It's tied to the NATO faction, and fires .338 Norma Magnum rounds in 130-round belt boxes.
Heckler & Koch MG5 A2 (*)
The other GPMG added by the Marksmen DLC was CSAT's Navid, also inspired by a real-world analogue, the Heckler & Koch MG5 A2. It fires in full-auto, and interestingly, a three-round burst fire mode that fires much, much faster than the full-auto mode. It's chambered for 9.3x64mm.
Metal Storm 3GL
The 3GL from Australian company Metal Storm is the standard underbarrel launcher of NATO forces, mounted on the MX rifle. It fires both normal 40mm grenades (which is realistically unlikely, given the 3GL's use of electronic firing through induction coils instead of primers and strikers) and stacked 40mm grenades (represented as "three-round magazines" in terms of game coding), in frag, flare and smoke variants. The in-game reload animation depicts the grenades as being muzzle-loaded instead of breech-loaded, for some reason.
The "EGLM" of CSAT's DIO KH2002 appears to be based on the ML40 40mm underbarrel grenade launcher from Madritsch Weapon Technology. It is visually different from the FN GL-1, and opens to the side instead of having a forward-sliding breech.
FN GL-1 launchers, named EGLM, are seen mounted on FN F2000 Tactical and Tavor TAR-21 rifles in-game. It fires frag, flare, and smoke rounds, of varying types.
The 9K115-2 Metis-M (NATO reporting name AT-13 Saxhorn-2) SACLOS wire-guided launcher was added to ArmA 3 for free in the Tanks DLC update released on April 11th, 2018, under the fictional designation of 9M135 Vorona (with the fictional NATO reporting name AT-19 Sweeper). It is exclusive to CSAT, used by both their Mediterranean and Pacific branch, and can fire HEAT tandem or HE missiles. It only exists as a man-portable launcher, which doesn't exist in real life but did previously appear in ArmA II.
Carl Gustaf M4
The Carl Gustaf M4 recoilless rifle was added to ArmA 3 for free in the Tanks DLC update released on April 11th, 2018. Despite being primarily trialed by the US Army in real life, it uses the Navy Mk / Mod naming scheme in-game, being designated MAAWS Mk4 with Mod 1 and Mod 0 being the two appearing variants. It is available to NATO (both Mediterranean and Pacific branches) and AAF, and used in limited numbers by CTRG and FIA. Mod 1 features an Aimpoint FCS12 computerized sight with a laser rangefinder, and is used exclusively by NATO and CTRG. The Mod 0 variant lacks this fire control system and uses a traditional optical sight, and is used by AAF and FIA.
Essentially the NATO counterpart to CSAT's RPG-42 unguided launcher, both variants of the MAAWS can fire HEAT tandem or HE munitions. Unlike the real Carl Gustaf M3 adopted under the MAAWS designation by the United States military whose designation stands for "Multi-Role Anti-armor / Anti-personnel Weapon System", the in-game MAAWS rather redundantly stands for "Multi-role Anti-armor Anti-tank Weapon System", according to the field manual. It's also used by the LDF in the "Contact" DLC.
The NLAW (British designation for the MBT LAW) is the standard launcher of NATO troops. It is designated the PCML in game, standing for Person-Carried Missile Launcher. Unlike the real NLAW, the in-game PCML is reloadable. It fires 150 mm missiles with HEAT tandem charge warheads, and uses a visual sensor for lock-on.
The game simulates the soft-launch system of the real MBT LAW; the missile is first launched out of the launcher with a low powered ignition, and the main rocket then ignites after the missile travels for a few meters. The missile has a flight time of 7 seconds, and self destructs if it fails to hit anything when it runs out of fuel.
The RPG-32 Hashim appears as the RPG-42 Alamut and is the standard CSAT launcher. Completely unguided, the RPG-42 can fire PG-42V HEAT tandem warheads or TBG-42V HE warheads. It's used by the Russian Spetnatz in the "Contact" DLC.
The Rafael Mini-Spike appears as the Titan MPRL (full name: Titan Multi-Purpose Rocket Launcher), in two variants: a full-size one with a fictional longer hexagonal tube that only takes anti-aircraft munitions, and a "Compact" version with the size and square profile of the actual Mini-Spike, which can take anti-tank or anti-personnel munitions. The AA missiles are thermal guided, the AT missiles are thermal guided and can also use SACLOS guidance from the Titan MPRL Compact, and can also fire in direct fire mode or in a top attack mode, while the AP missiles are purely SACLOS guided. Both Titan variants are universal to all factions, and also comes in tripod mounted variants. The launcher is described as using 127 mm missiles instead of the real Mini-Spike's 75mm missiles.
GE GAU-8/A Avenger
The General Electric GAU-8/A Avenger cannon appears as the main armament of the NATO "A-164 Wipeout" (derived from the A-10 Thunderbolt II) CAS jet.
Browning M2 Heavy Barrel
The Browning M2HB is seen mounted on the back of the Offroad Technical, used by the FIA faction in-game. It also features as part of the Remote Controlled Weapon System, or the RCWS, alongside the GMG.
The Tanks DLC added the "AWC 300 Nyx" (Armoured Weapons Carrier) for the GREENFOR, a tankette based on the Wiesel AWC. In it's 20mm autocannon armament, it's paired up with a coaxial MG3.
The Mk6 Mortar is an 82mm mortar resembling a futuristic M224 Mortar. It is available to all major factions except CSAT Pacific. It has access to HE shells, white smoke shells, and white parachute flares. Like other mounted weapons, it can be disassembled for easy transport.
Heckler & Koch GMG
The Heckler & Koch GMG is seen as part of the RCWS, and is mounted on a bevvy of Arma 3's vehicles.
The XM312 appears as the Mk30. It's used in tripods, raised tripods, autonomous tripods, and on patrol boats. It's used by the NATO, CSAT, and INDFOR factions.
The XM307 appears as the Mk32. It's used on tripods, raised tripods, and autonomous tripods. It's used by NATO, CSAT, and INDFOR factions.
Dillon Aero M134 Minigun
The DA M134 Minigun is seen mounted on the "AH-9" attack helicopter (derived from the AH-6 Little Bird) used by the NATO faction in-game. It's also seen on the Assault Boat, and on the PO-30 Orca CSAT helicopter.
General Dynamics XM301
The GD XM301 is seen mounted on the "AH-99 Blackfoot" attack helicopter (derived from the RAH-66 Comanche) used by the NATO faction in-game.
General Dynamics GAU-19/A
The GD GAU-19/A is seen mounted on the "Mi-48 Kajman" attack helicopter (derived from the Mi-28 "Havoc") used by the CSAT faction in-game. It is unclear why the GAU-19/A is featured as the main armament of the Mi-48 instead of the Shipunov 2A42, although this reason could be for ArmA III's futuristic background. It does act like the 2A42, switching from HE to AP without needing to re-chamber.
ZVI Plamen PL-20 2x20mm gun pod
The "A-143 Buzzard" multi-role light attack jet used by the AAF is a L-159 Alca, previously seen in the Army of the Czech Republic DLC for ArmA 2. It comes with its underslung ZVI Plamen PL-20 gun pod with dual 20mm cannons.
The USS Freedom, a Gerald R. Ford class aircraft carrier, comes with automated defenses and is available for free. The Phalanx CIWS are labelled as "Praetorian 1C AAA".
General Electric M61A2 (*)
A F/A-18 Super Hornet/F-22 hybrid designated "F/A-181 Black Wasp II" was added to BLUFOR in the Jets DLC. Its primary armament is a 20mm "M61 Minigun", likely referring to the real jets' M61 Vulcan.
"M61 Minigun" (*)
A JAS 39 Gripen was added to GREENFOR in the Jets DLC, designated "A-149 Gryphon". While the real JAS 39 Gripen is armed with a Mauser BK-27 27mm autocannon, the in-game Gryphon is armed with the same M61 Minigun as the Black Wasp II.
Gryazev-Shipunov GSh-30-1 (*)
The Jets DLC adds the "To-201 Shikra" stealth multirole fighter jet to the CSAT side that seems to be a Su-57/Mig-29 hybrid with a 30mm "Gsh Cannon", likely based on the Gryazev-Shipunov GSh-30-1.
M15 Anti-Tank Mine
The AT Mine is the M15 anti-tank mine. They're triggered when heavier vehicles drive over them; most civilian vehicles and quad bikes can drive over them without triggering them.
A slightly futuristic M18A1 Claymore appears as the Claymore Charge. The ArmA Claymore correctly demonstrates the real Claymore's command detonation, and can also be primed for a 40 second timed fuze. It has an effective kill radius of up to 50 meters, directed towards the front of the Claymore.
M18 Smoke Grenade
The Smoke Grenade model in ArmA 3 is the M18 smoke grenade. Colors available include white, red, orange, green, yellow, blue, and purple.
M67 Hand Grenade
The M67 Hand Grenade appears in-game as the RGO Grenade, which is actually the name of a Soviet hand grenade that stood for "Hand Grenade Defensive". Like the real RGO, it is heavier and releases more fragments, giving it a larger lethal area.
A "next generation" Selectable Lightweight Attack Munition known as the M6 SLAM is found in ArmA 3 (in real life, production terminated in 2002, and the number only went up to M4). They're directional anti-vehicle landmines triggered when a vehicle comes in range.
V40 Mini Grenade
The V40 Mini Grenade appears in-game as the RGN Grenade. Like the RGO Grenade, its name is also taken from a Soviet hand grenade, standing for "Hand Grenade Offensive". And just like the real deal, it is lighter and can be thrown farther, but releases less fragments, making it suitable for more offensive use.
The APERS Mine is a pressure-activated anti-personnel landmine. It seems to be based on a VS-50 or TS-50 anti-personnel mine.
Arma 3 Apex
The Makarov PMM appears as the standard backup pistol for the Syndikat militia forces. It's known as the PM in game, and is chambered for 9x21mm. The Field Manual describes the weapon as a Ukrainian made pistol based on the Makarov pistol, rechambered for 9x21mm. It uses its own 10-round magazines incompatible with any other 9mm pistols; the Field Manual notes that the PM's 9x21mm is shorter and wider (due to different caliber measuring procedures in Russia), making it incompatible with the international standard 9x21mm. It has no attachments.
Heckler & Koch MP5K
The Tanoan Gendarmerie Police use an MP5K with RIS and PDW stock. It's known in game as the Protector, and like most future SMGs, is chambered for 9x21mm in curved 30 round magazines (shared with the CZ Scorpion Evo 3 A1 coding-wise, thus the magazine icon is that of the Scorpion magazine).
Heckler & Koch HK416A5
The Heckler & Koch HK416A5 appears as the standard arm of CTRG Special Forces on Tanoa. It appears as the SPAR-16 (full name: Special Purpose Assault Rifle, only mentioned by the announcer in the NATO showcase) under a variety of variants; the standard assault rifle, SPAR-16S light support weapon with extended barrel, Beta C drum magazines (holding 150 rounds instead of the real 100) and vertical foregrip, and SPAR-16 GL equipped with the M320 GLM. It's chambered for 5.56x45mm, and has a bevvy of rails for attachments.
A modified version of the QBZ-95-1 appears as the standard arm of the Pacific forces of CSAT in a variety of configurations. It's known in its normal form as the CAR-95, and is chambered for 5.8mm. Its alternate variants are the CAR-95-1 light support weapon variant with extended barrel, integrated bipod, and exclusively using 100-round drum mags (an analogue to the QBB-95, though named in the style of QBZ-95-1), and the CAR-95 GL fitted with the QLG-10A grenade launcher.
It has the selector switch of the original QBZ-95 instead of the QBZ-95-1, located on the stock instead of on the grip. Rather than having its prominent carry handle, it has the railed upper receiver modification from T97.ca for the Type 97 NSR, a civilian version of the QBZ-97 5.56mm export model for the Canadian market. Unlike the reference image, the charging handle extends to the right instead of the left.
The 2012 prototype of the AK-12 appears in the Apex DLC with some odd mish-mash of capabilities from multiple variants. Like the prototype variation it's modeled after, it features full-auto, semi-auto, and burst-fire modes, bursts firing at a noticeably higher rate than the other modes; however, burst-fire is limited to two rounds at a time, which is something from the production version. It's also chambered in 7.62x39mm, presumably to keep the ammo in line with the AKM rifle, though a steel magazine on the AKM turns into a polymer magazine when used on the AK-12. It's used by the Syndikat faction.
In the Contact DLC, two additional variants of the AK-12 are added to the game, completing the family: the "AKU-12" (a misnomer of the planned AK-12U) carbine, and the "RPK-12" LMG variant. These are all used by the Russian Spetsnaz, and share the same 7.62mm chambering. In real life, these two prototype variants were only planned, and most likely didn't enter development stage, instead only existing on early photoshopped images. The 2016 iteration of the AK-12 design later developed carbine and LMG variants, those being AK-15K and RPK-16 respectively (though the RPK-16 only exists in 5.45mm), which look markedly different from the early designs appearing in-game.
The welcome return of the AKM is made in Apex. It's one of the very few main rifles with no points for attachments. It's chambered for 7.62x39mm, and is a standard arm of the Syndikat criminal faction.
The AKS-74U appears, the only weapon chambered in 5.45x39mm so far in the game. It's standard for Syndikat launcher users.
The Type 115 is a very, very strange addition. It seems similar to concepts like the H&K OICW and the Chinese QTS-11, combining two separate firearms into one case. In this case, the upper is a 6.5mm assault rifle, and the lower is a semi-auto only rifle in the .50 BW caseless round which is based off the .50 Beowulf round. It's used exclusively by the CSAT Special Forces "Viper" division.
Heckler & Koch HK417 A2
The Heckler & Koch HK417A2 appears under the name SPAR-17 as the standard DMR of the CTRG forces on Tanoa. It's chambered for 7.62x51mm, and has a variety of attachment points.
The QBU-88 appears under the name CMR-76 and is used by the CSAT Pacific faction as the standard DMR rifle. It's chambered for 6.5mm in exclusive 20 round magazines, and naturally, has lots of room for attachments.
The M249 Paratrooper appears as the standard LMG for Syndikat gunners, under the name LIM-85 (Light Infantry Machine gun). It has two different selectable firing speeds, one fast and one slow; the original FN Minimi has such a feature through its manually adjustable two-position gas valve with the settings normal and adverse, adverse increasing the ROF from 700–850 RPM to 950–1,150. The feature was eliminated on the M249, however. It's chambered for 5.56x45mm, has a heat shield, and a railed handguard that oddly enough seems to be patterned after the railed handguard of the Mk 46 Mod 1. It lacks M249's original bipod, and has an unremovable rail-mounted grippod instead.
The GP-25 is the underbarrel grenade launcher used by the Syndikat, mounted on AK-12s. Coding-wise, it uses the same 40mm grenade as ammunition as most grenade launchers in the game. Logically however, this would not work since the GP-25 uses caseless VOG-25 grenades instead of the cased 40x46mm grenades depicted on the menus and used on the other launchers. Animation-wise, the GP-25 is shown loading and firing caseless VOG grenades correctly.
Heckler & Koch M320
The Heckler & Koch M320 is the underbarrel grenade launcher for the CTRG special forces on Tanoa, mounted on their H&K HK416A5 assault rifles. It is named GLM on the HUD.
The QLG-10A, designated GL 15A, is the standard underbarrel grenade launcher for CSAT Pacific, mounted on their modified QBZ-95-1s. In-game, it fires the same 40mm grenades as everyone else, giving it the same grenade logic problems as the GP-25.
The RPG-7 appears as itself, and is the standard launcher for Syndikat forces. The only grenade the weapon can launch is the RPG-7V HEAT grenade. A neat detail is that the rear sight is animated based on the user's zeroing.
The V44-X Blackfish, the VTOL transport aircraft of NATO Pacific (based on a futuristic V-22 Osprey), comes in a gunship configuration that uses a GAU-12/U alongside the Bofors 40mm and M102 Howitzer, just like the real-life AC-130U.

Arma 3 Contact
Note: The AKU-12 and RPK-12, added in the Contact DLC, are covered in the AK-12 section found under the Arma 3 Apex heading. Likewise, the 10-round Mk14 variant added in Contact DLC is covered in the M14 section under the Arma 3 base game heading.
The Kozlice, Czech for over/under shotgun, returns from Operation Flashpoint in both sawn-off and full-length form. It appears to be a fictional version based on the Beretta DT-11 with elements of the CZ Drake, and commonly appears with Livonian hunters and looters.
Crye Precision SIX12
The Crye Precision SIX12 in its underslung configuration is available for use by Livonian forces, equipped on their Promet assault rifles. It is known in-game as the TSP-12.
FB MSBS GROT B16 FB-A0
The bullpup version of the FB MSBS GROT B16 FB-A0 appears as the Promet, the standard arm of the Livonian Defense Force. "Promet" is Polish for Promethium, reflecting the Polish tradition of naming rifles after minerals and elements.
Chambered in 6.5mm, the weapon is configured in four versions: a 16-inch barreled assault rifle (which would be designated as Grot B16FB in real life under the Polish naming system), the assault rifle with its proprietary GP grenade launcher ("Promet GL" in-game), the assault rifle equipped with the Six12 underbarrel shotgun ("Promet SG" in-game), or a 20-inch barreled marksman rifle (designated Grot B20PSFB under the Polish naming system, "Promet MR" in-game). The assault rifle can be equipped with a number of attachments, including a unique carry handle with an integrated scope.
The pistol grip and magazine are based on HS Produkt VHS 2 and the unique carry handle having same reference to VHS 2
Livonian forces can equip the MSBS's proprietary GP grenade launcher on their Promet rifles, which is known in-game as the UGP-40.
