Milsim, or military simulation, is a type of tactical game that attempts to accurately replicate a real-world military operation. Milsim events are often organized by airsoft and paintball groups, as the use of simulated weapons and tactics allows for the realistic portrayal of tactical situations without the need for actual firearms. Milsim events usually involve a large number of participants, and can range from a few hours to an entire weekend, with objectives that are tailored to the mission at hand. During milsim events, teams of players are typically outfitted with military-style clothing and gear and employ tactics that closely resemble those employed by real-world military forces. Milsim can also involve the use of simulated communications equipment, such as radios and walkie-talkies, as well as other props, such as smoke bombs and flashbangs. Milsim events offer participants the chance to engage in realistic combat scenarios in a safe, controlled environment, and can be great fun for both experienced players and newcomers alike.
