High Mobility Multipurpose Wheeled Vehicle (HMMWV) is a family of four-wheel drive cars, military trucks and commercial vehicles manufactured by AM General. It largely replaced the roles previously performed by the original jeep. The Humvee was widely used in the Gulf War in 1991, where it sailed through treacherous desert terrain; this use helped inspire civilian versions of the Hummer.
In 1979, the U.S. military developed specifications for a high-mobility multi-purpose wheeled vehicle (HMMWV) to replace all tactical vehicles. The specification required excellent road and off-road performance, the ability to carry heavy payloads and improved resistance to indirect fire.
The HMMWV first saw combat in Operation Just Cause, the US invasion of Panama in 1989. The HMMWV was designed primarily to transport people and light cargo behind the front lines, not as a front-line combat vehicle.
Model M966 / M966A1 TOW had basic armor, without a winch.
