The High Mobility Multipurpose Wheeled Vehicle (HMMWV), commonly known as the Humvee, is a four-wheel drive military automobile produced by AM General. It has largely supplanted the roles formerly served by smaller jeeps such as the M151 1⁄4-short-ton (230 kg) MUTT, the M561 "Gama Goat", their M718A1 and M792 ambulance versions, the CUCV, and other light trucks. Primarily used by the United States military, it is also used by numerous other countries and organizations and even in civilian adaptations. The Humvee's widespread use in the Persian Gulf War helped inspire the civilian Hummer automotive marque.
The Humvee uses independent suspensions and portal geared hubs similar to portal axles to make for a full 16 inches of ground clearance. The vehicle also has disc brakes on all 4 wheels, and 4-wheel double-wishbone suspension. The brake discs are not mounted at the wheels as on conventional automobiles, but are inboard, attached to the outside of each differential. The front and rear differentials are Torsen type, and the center differential is a regular, lockable type. There are at least 17 variants of the HMMWV in service with the United States Armed Forces. HMMWVs serve as cargo/troop carriers, automatic weapons platforms,ambulances (four litter patients or eight ambulatory patients), M220 TOW missile carriers,M119 howitzer prime movers, M1097 Avenger Pedestal Mounted Stinger platforms, MRQ-12 direct air support vehicles, S250 shelter carriers, and other roles. The HMMWV is capable offording 2.5 ft (76 cm) normally, or 5 ft (1.5 m) with the deep-water fording kits installed.
