MilSim includes activities that strive to provide an experience of combat, or military service, without planning to actually engage in real conflicts. There are several forms of MilSim: physical shooting sport (e.g. airsoft, paintball, or laser tag) with an emphasis on realism, based on military scenarios and team tactics; historical reenactment of famous battles; a focus on stylistic imitation of a military era, such as cosplaying; and military-themed e-sports (e.g. video games). Airsoft guns are used commonly in MilSim due to their cosmetic realism, satisfactory external ballistics, compatibility with genuine firearm accessories, and inexpensive ammunition, though blank guns may be used to add immersion in events such as MilSim West.
