Heavy vehicles are primarily used for the same range of purposes as the medium, such as carrying cargo, as dump trucks, or tractors. They haul heavy-duty loads including combat vehicles (e.g. tanks), engineer equipment (e.g. earthmovers) and weapon systems, ammunition, food, fuel, and other supplies. They are used for long-haul highway transports from ports to the theater of operations or more locally for tactical movement.
Originally heavy trucks were little more than a way to move cube and weight from one place to the other, within either a cargo body or as a tractor pulling a trailer or semi-trailer. Recent trends require much more as the U.S. Army and Marine Corps adopt technology-based logistic supply-chain management solutions to palletized presorted loads, electronically tracking and manageing them from origin to the destination unit in the field, minimizing handling, delay and risk. Vehicle systems such as PLS and LVS incorporate pallet racks or CONEX/ISO handling, cranes, remote operator controls, and other logistics productivity features.
Time Line of the U.S. Military Heavy Truck Fleet
The military heavy truck fleet includes trucks that were designed for military tactical requirements as well trucks such as the M915-series that were based on existing commercial designs which were then adapted for military use. The table gives the approximate time sequence of the heavy truck models that served the needs of the U.S. military.
