Trailers for Military Vehicles
Trailers are regularly fitted to military vehicles to increase cargo capacity or for hauling specialized equipment or weapons.
Each military truck, including jeeps, HMMWVs and other light vehicles, will have one or more trailers that are designated for use with it. Military trailers typically have the same wheel and tire size, load height, and track as the specified towing vehicle to maximize performance under all conditions and to simplify logistics.

Nearly all tactical vehicles (wheeled and tracked) are equipped with a standard towing pintle and trailer electrical cable receptacle. Trailers, in turn, are equipped with a standard lunette ring and inter-vehicle cable that mate with the towing vehicle. Compatible electrical voltage is also made available for trailer lights and any other requirements. Although the matched trailer is preferred, almost any trailer within a weight class and with matching voltage can be connected and pulled by any towing vehicle due to the standardization of connectors. In addition, some trailers required a towing vehicle that provided an air supply for brakes or other purpose.

There is some ambiguity and overlap in the use of the terms trailer and semitrailer. In the Olive-Drab.com charts of military trailers and semitrailers, the term trailer is used to describe a small trailer with one or two axles in the rear, for example a jeep trailer. Trailer also describes a larger vehicle with two or more axles, front and rear, so its entire weight is borne by its own wheels. The term semitrailer refers to a vehicle that has rear axles but no front axle assembly such that at least part of its weight is borne by the towing vehicle. A jeep trailer is thus technically a semitrailer, but the term is not used for such light trailers.
A few trailers have an integrated dolly at the front (e.g. Trailer, Tank, 45 Ton, M9) so they are both a semitrailer (not considering the dolly) or a trailer when the dolly is taken as part of the unit.
Chassis models are trailers or semitrailers that have the frame, axles, suspension, electrical etc. but do not have a body. The chassis model may be the base for a series of complete-body models, such as the M126 Chassis, Semitrailer that is the base for the M127 flatbed/stake body, the M128 / M129 van semitrailers. Or the chassis may be used to build specialized units (e.g. quartermaster, engineering or signal equipment) that require a sturdy trailer chassis for mobility.
