when did the military start using the humvee
Humvee In 1979, the U.S. Army drafted final specifications for a High Mobility Multipurpose Wheeled Vehicle (HMMWV), which was to replace all the tactical vehicles in the 1/4 to 1 1/4-ton range,[8] namely the M151 quarter-ton jeep and M561 Gama Goat, as one "jack-of-all-trades" light tactical vehicle to perform the role of several existing trucks.[9][unreliable source?] The specification called for excellent on and off-road performance, the ability to carry a large payload, and improved survivability against indirect fire.[10] Compared to the jeep, it was larger and had a much wider track, with a 16 in (410 mm) ground clearance, double that of most sport-utility vehicles. The new truck was to climb a 60 percent incline and traverse a 40 percent slope. The air intake was to be mounted flush on top of the right fender (or to be raised on a stovepipe to roof level to ford 5 ft (1.5 m) of water[11] and electronics waterproofed to drive through 2.5 ft (0.76 m) of water were specified. The radiator was to be mounted high, sloping over the engine on a forward-hinged hood.
