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) against the Sahrani Liberation Army (SLA). 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".

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.

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.
