The game will revolve around a war in the fictional ex-Soviet republic of Chernarus, which is being fought over by the government, communist rebels, the United States and the Russian Federation. In total there are around 81 variants of the weapons available in the game.
The Colt M1911A1 pistol is the standard sidearm of Marine Force Recon units.
Makarov PM
The Makarov PM pistol is the standard sidearm for most of the factions involved in the game, including the Russian Federation, Chernarussian Defence Forces, Chendaki rebels and NAPA insurgents. A suppressed version is also used by Russian Spetznaz soldiers.

The MP5SD6 submachine gun, distinguished by the presence of single, burst and auto firing modes and a Navy trigger group, is available in the game, though it is not standard equipment among any of the factions.
