Military transport refers to the movement of personnel, equipment, and supplies by land, sea, or air. Two common forms of military transport are jeeps and humvees. Jeeps are four-wheel drive vehicles that are used for reconnaissance and light transport. Humvees are six-wheel drive vehicles that are used for heavier transport and can be outfitted with weapons. Both jeeps and humvees are used by the military for transportation in a variety of environments.
