POTD: Nigerian Navy SBS with Training with Paintball Guns

    Isaac emailed us this photo of the Nigerian Navy SBS (Special Boat Service) special forces training with Tippmann U.S. Army Project Salvo paintball markers. These .68 caliber paintball guns are patterned after the AR-15 and include an M4-style 6 position stock and quad rails. The US Army designation is just commercial branding.
