ARMA 2: Operation Arrowhead is a standalone expansion to the original ARMA 2 and does not require the original game in order to play.

Three years after the conflict in Chernarus, portrayed in the original ArmA 2, a new flashpoint in the Green Sea region heats up. Coalition forces led by the US Army are sent to Takistan to quickly restore peace and prevent further civilian casualties in this standalone expansion pack to ArmA 2. You will enlist into various roles within the US Army, from basic infantrymen, through special operatives, to pilots and tank crew in this new installment in the award winning line up of military simulators for PC from Bohemia Interactive.
