ArmA II: Reinforcements

Arma II: Reinforcements is a standalone expansion pack to Arma II that brings two new factions to the Arma universe. The two factions are the British Armed forces and the Private Military Company. Players can play through the British Armed Forces campaign to reinforce coalition troops and battle a large-scale outbreak of guerilla insurgency with a mechanized division. Players can also join the Private Military Company, which has been recently contracted to protect a UN weapons inspection team in Takistan. Arma II: Reinforcements allows the player to play the game separately or combine with the original Arma II: Combined Operations for the ultimate military combat experience. Players can also join in on the massive online multiplayer battles with up to 50 players and hundreds of AI units.
