I thought I'll post a photo of a WWII "themed" paintball scenario game from eastern front we took part in recently. It is of course nowhere near the reenactment quality, only half of the players had uniforms resembling the real ones. There were three vehicles on the game (one armoured one - sadly a post war model) and our working anti-tank gun. The gun shoots safe "AP" projectiles over pretty long distance and was purchased from these guys: Paintball Artillery Systems | SEAR
