MilSim is an abbreviation of military simulation, and refers to military simulations conducted by civilians for entertainment purposes. There are several forms of MilSim: airsoft games, paintball games, and video games simulating military scenarios and tactics. Weapons used in MilSim are commonly airsoft guns. Airsoft guns are used more often in MilSim than paintball guns due to their availability as replica weapons without any modification.

Gameplay varies in style and composition but often range from short-term skirmishes, organized scenarios, C.Q.B., field, military simulations (MilSim), or historical reenactments and indoor airsoft fields.[1] Combat situations on the battlefield may involve the use of military tactics to achieve objectives set in each game. Participants may attempt to emulate the tactical equipment and accessories used by modern military and police organizations.
