The Commercial Utility Cargo Vehicle (CUCV) (later Light Service Support Vehicle (LSSV) is a vehicle program instituted to provide the United States military with light utility vehicles based on civilian trucks.

General Motors and AM General have produced CUCVs since 1984 in three distinct generations: CUCV, CUCV II, and LSSV. Replacing the M880/M890 series, the CUCV represented General Motors' first major light-truck military vehicle production since World War II. GM CUCVs were assembled mostly from existing heavy duty light commercial truck parts. The CUCVs came in four basic body styles: pickup, utility, ambulance body and chassis cab. The M1008 was the basic cargo truck, the M1010 was the ambulance, and the M1009 was a Chevrolet K5 Blazer uprated to 3/4-ton capacity. With the exception of the M1009, the trucks were all rated as 11/4 ton (commonly called a "five-quarter"), even though some of them had payloads in excess of that. There were heavier-duty variants, including the M1028, M1028A1, M1028A2 and M1028A3 shelter carriers (the shelter being a mobile command, communications or intelligence operations enclosure). The M1031 was the chassis cab. These latter trucks were all rated for heavier 3,600 lb (1,600 kg) or 3,900 lb (1,800 kg) loads, compared to the M1008s 2,900 lb (1,300 kg) load capacity. The M1028A2 (converted M1031 or m1028a1) and m1028A3 (converted M1028) models had dual rear wheels. Many M1028s were upgraded at the company level to M1028A2 and A3 specs—the dual wheel rear end arrangement was a result of the M1028 flipping on its side because of the high center of gravity when carrying equipment shelters.

GM produced some 70,000 CUCVs from 1983 to 1986 (model years were 1984–1987), though most were model year 1984. Chevrolet continued to build CUCVs in low numbers from 1986 to 1996, mainly to accommodate military markets that needed replacements for existing CUCVs.

Controls

• Roll for steering
• Pitch for forward and backward movement
• AG1 to keep upright.

Notes

• This is probably one of the few things I've made with no weapons.
