This side of a tank, there is no more iconic U.S. Army vehicle that the High Mobility Multipurpose Wheeled Vehicle (HMMVV), or as it's better known, the Humvee. Design on them started in the late 1970s, with the Jeep-like vehicles first delivered in the mid-1980s. Humvees invaded Iraq twice, carrying soldiers and marines rapidly over desert. A wide range of equipment configurations made the HMMVV at times a troop carrier, an ambulance, and anti-tank tool, and an artillery pack mule. As useful as the vehicle was fighting against Saddam Hussein's Iraqi military during the Iraq War, it suffered on counterinsurgency patrols, as its light weight left it vulnerable to powerful roadside bombs. Yesterday, the Army announced the contract for the Joint Light Tactical Vehicle program: Oshkosh's Light Combat Tactical All-Terrain Vehicle, or L-ATV.
