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.

A ground combat vehicle, also known as a land assault vehicle or simply a combat vehicle or an assault vehicle, is a land-based military vehicle intended to be used for combat operations. They differ from non-combat military vehicles such as trucks in that they are designed for use in active combat zones, to be used in mechanized warfare and mobile infantry roles.
