This is a Gama Goat model, which depicts the ambulance version of that unique 6-wheel drive U.S. military vehicle. The Gama Goat was originally commissioned in 1966 as an off-road, amphibious vehicle, a 6-wheel drive truck consisting of a 4-wheel tractor and a 2-wheel carrier module. It employed an articulation joint between the two modules that allowed them to move independently of one another, allowing goat-like nimble traversing of rough terrain. The M792 ambulance truck variant featured additional seats that could be folded out to make a bed for the wounded, a heater to warm up the rear carrier module, and a canvas roof to protect its passengers from the elements. The M792 was deployed in the Invasion of Grenada which took place in 1983.
