Military light utility vehicle, or simply light utility vehicle (LUV), is a term used for the lightest weight class military vehicle category. A Jeep-like four-wheel drive vehicle for military use by definition lighter than other military trucks and vehicles, inherently compact and usually with light or no armour, with short body overhangs for nimble all-terrain mobility, and frequently around 4-passenger capacity.

A military vehicle is any vehicle for land-based military transport and activity, including combat vehicles, both specifically designed for or significantly used by military. Most military vehicles require off-road capabilities and/or vehicle armor, making them heavy. Some have vehicle tracks instead of just wheels; half-tracks have both. Furthermore, some military vehicles are amphibious, constructed for use on land and water, and sometimes also intermediate surfaces.
