The Palletized Load System (PLS) is a truck-based logistics system that entered service in the United States Army in 1993. It performs line haul (long distance), local haul (short distance), unit resupply, and other missions in the tactical environment to support modernized and highly mobile combat units. It provides rapid movement of combat configured loads of ammunition and all classes of supply, shelters and containers. It mirrors similar systems in use with the British (Demountable Rack Offload and Pickup System (DROPS)) and other armed forces.
