Chevrolet K51 Panel Van. Signal truck

The G-506 trucks, 1+1⁄2-ton, 4×4, produced as the Chevrolet G7100 (and originally G4100) 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 G506 was a United States Army Ordnance Corps supply catalog designation for the 1+1⁄2-ton, 4X4, truck chassis built in large numbers by the Chevrolet Motor Division of GM. Their official model numbers were initially the “G4100”, and later the “G7100” series. They became standard 1+1⁄2-ton 4×4 trucks for the US Army and Army Air Corps during World War II.

During World War II, the US military purchased a total of 167,373 four by four 11⁄2-ton trucks, and Chevrolet supplied the great majority of them. According to the 1946 revision of the U.S. military’s Summary Report of Acceptances, Tank-Automotive Materiel, Dodge (Fargo) – the initial standard supplier of U.S. 1+1⁄2-ton 4×4 trucks – contributed 6,762 VF model, G-621 series trucks in 1940; and Ford (Marmon-Herrington) and Diamond T supplied another 6,271 and 136 units respectively, leaving 154,204 Chevrolet trucks.

However, some 47,700 of the G7107 and G7117 model trucks were shipped to the Soviet Union as part of the Lend-Lease program. The Soviet Red Army’s logistics/transport capabilities improved dramatically in the spring and summer of 1943 largely as a result of the steady supply of American-made trucks (such as Studebaker US6s and the Chevrolet G506s) for the USSR.
