Designed by Chance-Vought Aircraft and built from 1969 to 1973, the M561 is a six-wheel drive semi-amphibious off-road 1 ¼ ton cargo truck used by the U.S. military in the Vietnam War. The front and rear units are connected and articulated but do not bend around turns. The steering was unusual in that the front and rear wheels turned in opposite directions, making for wide turns. The body is aluminum to help reduce weight for “swimming,” but its amphibious characteristics were limited to calm water fording only. The nickname Gama Goat derived from the name of the inventor of its powdered articulated joint, Roger Gamaunt, and Goat referenced its mountain goat like off-road capabilities. As for its appearance, beauty is in the eye of the beholder. This example was manufactured circa 1970 and has a USMC paint scheme and Detroit Diesel 3-53N 3 cylinder diesel engine. Over 1,700 Gama Goats were built for the USMC. It comes with a spare tire. Consignor research is included.
