Airsoft is a modern combat simulation sport that has been around for more than 30 years. Players eliminate opponents or practice hitting targets with spherical airsoft pellets that are launched from varying types of airsoft weapons.  

Airsoft is generally a very safe sport. When compared to paintball, the rounds deliver far less energy when striking a target. A round weighing .20 grams and traveling at 300 feet per second transfers about 1 joule of energy. A typical paintball round weighing 3.00 grams traveling 300 feet per second transfers about 12 joules. This typically means the BBs cause far less damage. Although airsoft BBs can leave a small welt at close range they are much smaller and generally far less painful than their paintball counterparts.
