In this, the Group G series numbers were designated to represent "Tank / Automotive materiel" – the various military vehicles and directly related materiel. These designations represent vehicles, modules, parts, and catalogs for supply and repair purposes. There can be numerous volumes, changes, and updates under each designation. The Group G list itself is also included, being numbered G-1.
Generally, the G-series codes tended to group together "families" of vehicles that were similar in terms of their engine, transmission, drive train, and chassis, but have external differences. The body style and function of the vehicles within the same G-number may vary greatly.
"Armored, half-track, and scout cars; gun, howitzer, and mortar motor carriages; cargo, mortar, personnel, half-track and universal carriers; armored amphibian, light, medium, and heavy tanks; light, medium, heavy, crane and amphibian/track-type tractors; wheeled tractors; armored, bomb, heavy-duty and tractor crane trailers; tank recovery and tank transporter trailer trucks, with their parts and equipment. Ordnance maintenance bomb service, emergency repair, machine shop and repair trucks, with their parts and equipment. Prime movers, passenger cars, fuel tank trucks, fuel and water tank trailers, and semitrailers; trucks, with stake, platform, dump, and special bodies; amphibian cargo and personnel trucks; motorcycles and side cars."

This page details tank production by the United States of America during World War II.
The Studebaker US6 (G630) was a series of 2+1⁄2-ton 6×6 and 5-ton 6×4 trucks manufactured by the Studebaker Corporation and REO Motor Car Company during World War II. The basic cargo version was designed to transport a 2+1⁄2-short-ton cargo load over any type of terrain in any weather. Most of these were exported to the Soviet Union under Lend-Lease by the US during World War II, since the competing GMC 6×6 CCKW design proved to be more suitable for Western Front conditions.
The 155 mm Gun Motor Carriage M40 was an American self-propelled artillery vehicle built on a widened and lengthened Medium Tank M4A3 chassis, but with a Continental engine and with HVSS, which was introduced at the end of the Second World War.
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.
Truck classifications are typically based upon the maximum loaded weight of the truck, typically using the gross vehicle weight rating (GVWR) and sometimes also the gross trailer weight rating (GTWR), and can vary among jurisdictions.
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.
Ben Hur trailer was the nickname of the World War II U.S. Army Trailer, 1-ton payload, 2-wheel, cargo, and the Trailer, 1-ton payload, 2-wheel, water tank, 250 gallon. Specialized variants were also manufactured.
The G-506 trucks, 1+1⁄2-ton, 4x4, produced as the Chevrolet G7100 models, were a series of (light) medium four wheel drive trucks used by the United States Army and its allies during and after World War II. This series came in standard cargo, as well as many specialist type bodies.
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.
The Autocar Model U8144T, officially "5- to 6-Ton, 4×4, Ponton Tractor Truck", was the largest, and most heavy-duty, of a family of heavy four-wheel drive trucks developed for, and deployed primarily with, the United States Army in World War II. They were of a "cab over engine" design, and produced by the Autocar Company from 1941 to 1945 with 2,711 being built.
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 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.
The Diamond T 4-ton 6×6 truck was a heavy tactical truck built for the United States Army during World War II. Its G-number was G-509. Cargo models were designed to transport a 4-ton (3,600 kg) load over all terrain in all weather. There were also wrecker, dump, and other models. They were replaced by the M39 series 5-ton 6×6 trucks in the 1950s.
