ArmA: Armed Assault (also known as ArmA: Combat Operations in North America and simply referred to as "ArmA") is the first installment of the ArmA series, considered as the spiritual successor to the original Operation Flashpoint. It was released in North America on May 4, 2007.
The storyline revolves around a war in the fictional island of Sahrani, which was divided into two regimes; Democratic Republic of Sahrani - DRS in the north, and Kingdom of South Sahrani in the south. The player takes the role of a United States Army soldier fighting with his platoon and collaborating with the Royal Army Corps of Sahrani (RACS, based on the Saudi Arabian Army) against the Sahrani Liberation Army (SLA, based on the Yemeni Army). Like Operation Flashpoint, the campaign also allows players to fight as a Special Forces Operative, a Main Battle Tank crewman and a Helicopter Transport/Attack pilot.
An expansion pack called ArmA: Queen's Gambit was released on September 28 in the same year and features new weapons, new characters (including Mercenaries and Partisans), new missions, two new storylines and gameplay improvement.
The following weapons appear in the video game ArmA: Armed Assault and its expansion pack, ArmA: Queen's Gambit:
The Beretta M9 is the standard issue sidearm for both the US and RACS factions. An M9 fitted with AAC EVOLUTION 9mm suppressor is also available for Special Forces operators.
Trivia: The expression "STFU" is engraved on the M9's slide in-game, and is the initials for "Shut The F*** Up".
Makarov PM
The Makarov PM is the standard sidearm for the SLA faction in-game.
Makarov PB
The suppressed Makarov PB is used by SLA commandos. It is referred to as the 69P in-game.

The H&K MP5A5 is the standard-issue weapon for the RACS Helicopter and Vehicle crewman, with the ability to fire semi-automatic, with three-round bursts or full-automatic.
Heckler & Koch MP5SD6

Assault Rifle and Carbines
Colt M4 Carbine
The standard-issue weapon for the US in-game is the original M4 Carbine, which fires in either semi-automatic or with three-round bursts, unlike the later M4A1 which can fire at full-automatic. It is available with either standard ironsights, M68 Aimpoint CCO or a Trijicon ACOG, as well as the M203A1 Grenade Launcher.
Colt M4A1 Carbine
The full-automatic M4A1 Carbine also appears in-game, mounting either standard ironsights, the M68 Aimpoint CCO or a Trijicon ACOG, as well as the M203A1 Grenade Launcher. The M4A1 Carbine used by Special Forces operatives also mounts a KAC QDSS-NT4 suppressor and a Surefire Tactical Flashlight. All models except the latter are fitted with an AN/PEQ-2 IR Designator.
Colt M16A2
The M16A2 is the standard-issue weapon of the RACS in-game, available with only standard ironsights, although it can be fitted with an M203 Grenade Launcher. It can be fired at either semi-automatic or with three-round bursts.
Colt M16A4
The M16A4 is introduced with the 1.04 update, and standard in the Queen's Gambit expansion pack, where it is used primarily by the USMC. It can be fitted with a Trijicon ACOG or standard ironsights and the M203A2 Grenade Launcher, although all models are equipped with the AN/PEQ-2 IR Designator.
Heckler & Koch G36
The Heckler & Koch G36, fitted with a ZF 3x4° dual optical sight, is carried by the RACS Royal Marksman class. It can be fired at semi-automatic, in (incorrect) three-round bursts and full-automatic.
Heckler & Koch G36K
The Heckler & Koch G36K, fitted with a ZF 3x4° dual optical sight, is used by the Mercenary Team Leader class. It can be fired at semi-automatic, in (also incorrect) three-round bursts and full-automatic.
Heckler & Koch G36C
The Heckler & Koch G36C is used by the RACS Royal Guard class. For some reason, even though possible, the G36C is fitted with a standard carry handle/ZF 3x4° dual optical sight instead of its original rail-top carry handle as seen below, and also erroneously features a three-round burst fire mode.
Izhmash AK-74
The AK-74 is the main weapon of the SLA. It can be fitted with a GP-25 Grenade Launcher. It fires in semi-automatic or full-automatic.
Izhmash AKS-74
The AKS-74, fitted with a PSO-1 scope and used by the SLA Especas Marksman class, is introduced in the 1.04 update.
Izhmash AKS-74U
The AKS-74U is used by SLA Helicopter and Vehicle Crewman, as well as by Especas operatives. The Especas Saboteur class use a model referred to as the AKS-74UN and fitted with a PBS-4 Cound suppressor. It is erroneously listed as a "submachine gun" in-game, although understandable due to it's small length compared to most assault rifles or carbines.
Sniper Rifles
Barrett M107
The Barrett M107 was introduced in the v1.04 update.
Izhmash SVD Dragunov
The SVD Dragunov is the standard-issue sniper rifle for the SLA in-game.
Mark 12 Mod 0 Special Purpose Rifle
The Mk 12 Mod 0 SPR is used by US and Mercenary designated marksmen. The Mk 12 can be loaded with a 30-round magazine, though it erroneously uses a model of a 20-round magazine.

The M24 SWS is the standard issue sniper rifle for the US and RACS forces in-game, and features a woodland camouflage scheme.
ZiD KSVK
The KSVK was introduced in the v1.04 update as the counterpart to the Barrett M107.
Machine Guns
FN M240G
The M240G is used as a General Purpose Machine Gun (GMPG) by the US forces, as well as the standard-issue machine gun for the RACS. Note that whilst the M240G is correct for the USMC forces depicted in-game, the M240B would be more accurate for the US Army faction. It is also mounted in both US and RACS machine gun nests.
FN M249-E2 SAW
The M249-E2 SAW is used by the US Automatic Rifleman class.
ZiD PKM
The PKM is the standard-issue machine gun for SLA forces. It is also mounted in SLA machine gun nests, on the back of the Datsun and Hilux "Technicals", and door-mounted on the Mi-17 Transport Helicopter.
Launchers
FIM-92F Stinger
The FIM-92F Stinger is used by the US and RACS forces in-game. It is also seen in a static twin-turret mount.
FGM-148 Javelin
The FGM-148 Javelin is used by USMC anti-tank gunners. Funnily enough, not only the Command Launch Unit (CLU) have a rather generic tracking system, the animation shows the rocket apparently being launched with the CLU! A waste of $125,000.
The M136 AT4 is the standard anti-tank weapon for the US and RACS forces. It is erroneously depicted as reloadable despite the real-life AT4 being a disposable, "fire and forget" weapon. The reload animation also depicts the imaginary warhead as being loaded into the front of the weapon, making one suspect the reload animation is copied from the SLA RPG-7V. This errors are also depict in Operation Flashpoint.
M203 / KAC M203A1 / M203A2 Grenade Launchers
The M203 is featured in three different models in-game: the original M203 fitted on the RACS M16A2, the M203A1 fitted on the US M4 and M4A1 Carbines, as well as the M203A2 fitted on the USMC M16A4.
RG-6 Grenade Launcher
The RG-6 Grenade Launcher, referred to as the 6G30 in-game, was introduced in the Queens Gambit expansion pack for use by the SLA.
SA-7 Grail (9K32 Strela)

Browning M2HB
The Browning M2HB appears in numerous configurations in the game. It is used by the US as static, mounted on an M3 tripod and a stand. (The RACS also use a stand-mounted M2HB).

The DShKM is used by the SLA as static. It is also mounted on the back of the Datsun and Hilux "Technicals", the turret of the UAZ-469 and the Commander's Hatch of the T-72 (also used by the RACS), although the NSVT would be more accurate for the latter.
FN M240C
The M240C machine gun is mounted coaxially on the M1A1 Abrams Main Battle Tank.
The General Dynamics GAU-17/A is door-mounted on the UH-60 Blackhawk and is the primary armament of the AH-6 "Little Bird" used by the US and RACS. It is referred to in-game as the M134 and can be fired at 2000 or 4000 rpm.
The GD M197 Vulcan is mounted on the US AH-1Z Viper helicopter. Erroneously though, sometimes the Viper is referred to as the "AH-1W Super Cobra" in-game, the variant which the AH-1Z is based on. Also, it will be more accurate to see the AH-64 Apache or AH-64D Apache Longbow used by the US Army faction.
