What is Airsoft?

Airsoft is a combat simulation game that is similar to paintball, but uses completely different equipment, and is much more realistic in its play and game style. Airsoft players usually use AEGs (Automatic Electric Guns), that fire small plastic BBs at their opponents to eliminate them from the game. Other types of Airsoft guns can also be used including gas or CO2 powered or spring powered, that required the user to cock the gun to fire.

Airsoft is played on the honor system as the BBs do not leave a tell tale mark or paint. There are referees, O.C.s or other game officials to facilitate the safety, hit calling and operation of the game. Airsoft games or scenarios do not use "Capture the flag", but instead utilize a much more realistic scenario system. Prior to events players are organized into teams, armies or units, and given missions to complete or objectives to accomplish, while the other team must try to stop them, or complete different objectives of their own.
