Gama Goat 6x6 Off-road Test - Military Truck

The Gama Goat was a six-wheel-drive semi-amphibious off-road vehicle originally developed for use by the US Military in the Vietnam War. The 'Goat used an articulated chassis, so that from distance it appears to be a four-wheel drive vehicle pulling a two-wheel trailer, but it is a single six-wheel vehicle with a four-wheel steering arrangement with the front and rear wheels turning in opposite directions. It was famous for its ability to travel over exceptionally rough and muddy terrain. The vehicle's nickname came from two sources; "Gama" from the name of the inventor of its powered articulated joint, Roger Gamount, and "Goat" for its mountain goat-like off-road ability. Its military designation was M561, 6×6 tactical 1-1/4-ton truck. There was also an ambulance version known as the M792. The 'Goat is prized among military vehicle collectors because it is so unusual and in short supply. The vehicle was replaced by the CUCV and HMMWV.
