This papercraft is the No.6 car "The Army Surplus Special", is the vehicle used by Sgt. Blast and Private Meekley, based on the anime Wacky Races. Wacky Races is an American animated television series produced by Hanna-Barbera. The paper model is designed by Webdude. Two soldiers, one a sergeant and the other a private, racing in an army tank/jeep hybrid with a small steamroller‘s wheel attached to the front. The Army Surplus Special makes use of its tank facilities while racing, including its cannon, which can spin around to face forward or back, and the hatch, where Sergeant Blast rides.
The Surplus Special is equipped with a supply of land mines and back-mounted thrusters. The Surplus Special fires its gun backwards to propel itself forwards for extra speed. As their names suggest, Private Meekly is very meek and merely follows orders without question, while Sergeant Blast "blasts" orders in a stereotypical drill-sergeant voice.
