ArmA 3 MilSim
Groups like Task For 121 ArmA MilSim emulate the Army branch from the U.S. Military and use real military tactics during “operations”. Four nights a week there are official games, “ops”, where someone will Zeus and create a real life scenario that the military must engage in. The clan is broken into several units such as Combat Applications Group (CAG), 75th Rangers Regiment, 160th SOAR, 66th Armored Regiment, and the 49th Field Artillery. Each unit will have responsibilities and make plans for the op. There is a chain of command and there are promotions that allow players to work themselves up through the ranks.
