The Medium Tactical Vehicle Replacement (MTVR) is a series of vehicles used by the U.S. Marines. The first MTVRs were delivered in late 1999. The MTVR is the equivalent of the U.S. Army's Family of Medium Tactical Vehicles (FMTV); the Marines do not use the FMTV and the Army does not use the MTVR.
Six-wheel drive is an all-wheel drive drivetrain configuration of three axles with at least two wheels on each axle capable of being driven simultaneously by the vehicle's engine. Unlike four-wheel drive drivetrains, the configuration is largely confined to heavy-duty off-road and military vehicles, such as all-terrain vehicles, armored vehicles, and prime movers.
An artillery tractor, also referred to as a gun tractor, is a specialized heavy-duty form of tractor unit used to tow artillery pieces of varying weights and calibres. It may be wheeled, tracked, or half-tracked.
The M35 2½-ton cargo truck is a long-lived 2½-ton 6×6 cargo truck initially used by the United States Army and subsequently utilized by many nations around the world. Over time it evolved into a family of specialized vehicles. It inherited the nickname "Deuce and a Half" from an older 2½-ton truck, the World War II GMC CCKW.
The M39 series 5-ton 6×6 truck (G744) was a family of heavy tactical trucks built for the United States Armed Forces. The basic cargo version was designed to transport a 5-ton (4,500 kg), 14 ft (4.3 m) long load over all terrain in all weather. In on-road service the load weight was doubled.
The GMC CCKW, also known as "Jimmy", or the G-508 by its Ordnance Supply Catalog number, was a highly successful series of off-road capable, 21⁄2-ton, 6×6 trucks, built in large numbers to a standardized design for the U.S. Army, that saw heavy service, predominantly as cargo trucks, in both World War II and the Korean War. The original "Deuce and a Half", it formed the backbone of the famed Red Ball Express that kept Allied armies supplied as they pushed eastward after the Normandy invasion.
The M25 tank transporter (G160) was a combination 6x6 M26 armored heavy tank transporter/tank recovery tractor and companion 40-ton M15 trailer introduced into US Army service in Europe in 1944–45. Manufactured by Pacific Car & Foundry Co., it was a substantial upgrade over the Diamond T M19 transporter/trailer duo introduced in 1940.
The Dodge WC series is a prolific range of light 4WD and medium 6WD military utility trucks, produced by Chrysler under the Dodge and Fargo marques during World War II. Together with the 1⁄4-ton jeeps produced by Willys and Ford, the Dodge 1⁄2‑ton G-505 and 3⁄4‑ton G-502 trucks made up nearly all of the light 4WD trucks supplied to the U.S. military in WWII – with Dodge contributing some 337,500 4WD units.
Motor transport (MT) refers to the operation and maintenance of a military vehicle fleet, and sometimes to the servicemembers to operate and maintain them.

Mack Trucks has been selling heavy duty trucks and buses to the United States military since 1911. Virtually every model has been used. The majority have been commercial models designed and built by Mack with their own components, but they have also designed and built military specification tactical trucks. The military vehicles are rated by payload measured in tons.
The M809 Series 5-ton 6x6 truck (G908) was a family of heavy tactical trucks built for the United States Armed Forces. The basic cargo version was designed to transport a 5-ton (4,500 kg), 14 ft (4.3 m) long load over all terrain in all weather. In on-road service the load weight was doubled. Built by AM General, they evolved into the M939 Series.
The 5‑ton 6x6 truck, officially "Truck, 5-ton, 6x6", was a class of heavy-duty six-wheel drive trucks used by the US Armed Forces. The basic cargo version was designed to transport a 5-ton (4,500 kg) load over all roads and cross-country terrain in all weather. Through three evolutionary series there have been component improvements, but all trucks were mechanically very similar. They were the standard heavy-duty truck of the US military for 40 years, until replaced by the Medium Tactical Vehicle (MTV) beginning in 1991.
The 2+1⁄2-ton, 6×6 truck was a standard class of medium duty trucks, designed at the beginning of World War II for the US Armed Forces, in service for over half a century, from 1940 into the 1990s. Also frequently known as the deuce and a half, or just deuce, this nickname was popularized post WWII, most likely in the Vietnam War era. The basic cargo versions were designed to transport a cargo load of nominally 2+1⁄2 short tons over all terrain, in all weather. The 2+1⁄2-ton trucks were used ubiquitously in World War II, and continued to be the U.S. standard medium duty truck class after the war, including wide usage in the Korean and Vietnam Wars, as well as the first Gulf War.
