Airsoft is a hugely popular recreational sport, similar to paintball, where teams compete to eliminate opponents by shooting them with small, spherical plastic projectiles (BBs) fired from realistic replica firearms. Since the plastic BBs do not leave a visible mark like paint, the game relies heavily on an "honor system," where players who are hit must honestly call themselves out of play. Gameplay scenarios range from casual skirmishes to elaborate military simulations (MilSim), emphasizing tactical movement, teamwork, and the use of replica tactical gear in both indoor and outdoor fields.
