A paintball tank, also known as a paintball armoured vehicle (PAV) is a vehicle, or a portable structure that resembles a vehicle, sometimes used in the sport of paintball, usually with the intent of military simulation. The purpose of the tank is to provide a mobile shelter for one or several players, from which they may employ their markers against players on the opposing team. Small pneumatic guns, effectively low-powered potato cannons loaded with foam darts, are also often employed against other tanks.
Paintball tanks are commonly used for woodsball and scenario paintball games, and similar designs have also seen use in Airsoft scenario games, with varying degrees of similarity to a true tank.
