The Dodge WC series was a prolific range of light 4WD and medium 6WD military utility trucks, produced by Dodge/Fargo during World War II. Dodge WC-series came in many purpose-built variants from the factory. The WC series evolved out of, and was part of a more extended family of trucks, with great mechanical parts commonality, that included open- and closed-cab cargo and weapons carriers, command cars, reconnaissance vehicles, telephone installation trucks, panel vans, carryalls, ambulances and mobile workshops. From 1940 to 1942, almost 82,400 1⁄2-ton 4x4 Dodge trucks were built. WC was not an abbreviation of "Weapons Carrier", but a Dodge model code – initially W for 1941, and C for half-ton rating.—Wikipedia
