The twins' ultra-mini tank - the Badger - secures a spot in the Guinness Book of World Records for "Smallest All-Terrain Armored Vehicle." The recognition inspires them to beef-up the Badger's armor so they can market the tank to SWAT teams and bomb squads. As a reward for completing the Badger, Mike and Geoff will treat the shop crew to a survival trip in the woods. After a long, hard weekend of work, H&H finishes the Badger just in time to test its armor. But will their new design stand up against high caliber guns and deadly amounts of TNT?
