High-Mobility Multipurpose Wheeled Vehicle, the official(?) acronym for the vehicle more commonly known as the Humvee. The Humvee was designed by AM General as a replacement for the aging Jeep design. It's less susceptible (seemingly almost impervious) to the Jeep's rolling problems, can carry more equipment, and was designed to serve in a more modern battlefield. The Humvee is also unusually designed to sink as quickly as possible in water. Thanks to an intake snorkel on the top of its hood, it can drive through almost any body of water, as long as the snorkel is above the surface.
