===Military Adaptations===
The Commercial Off The Shelf (COTS) concept, which became the Commercial Utility Cargo Vehicle (CUCV) program, was intended to augment the purpose-built but expensive Gama Goat 6x6, 1¼-ton trucks and M151 series ¼-ton "jeeps" nearing the end of their service life in the mid-1970s. 
The CUCV program name was changed to Light Service Support Vehicle (LSSV) in 2000
==== CUCV I====
In the mid-1980s, Chevrolet C/Ks replaced Dodge vehicles in CUCV I and CUCV II guise.
The C/K Series CUCV came in four basic body styles, based on an improved K30 or K5 chassis and running gear: 
*M1008 - 1¼-ton cargo truck (Often referred to as a "D30" or K3500 for post-1987 models)
*M1008A - 1¼-ton communications
* M1009 - ¾-ton utility (K5)
* M1010 - 1¼-ton ambulance
The CUCV I was not just an adapted C/K series truck, but an entirely re-engineered package. There were many variants of these basic styles.
GM produced some 70,000 CUCVs from 1983 to 1986 (model years 1984–1987), though most were model year 1984.
==== CUCV II====
The second CUCV program began in 1987 and carried through to 2001. These units were basic civilian Chevrolet C/K, Tahoe, and Suburban units sent for aftermarket paint and body upgrades, as well as the addition of a 24VDC starting and radio power system (The remainder of the vehicle was 12VDC). 
All CUCV IIs were manufactured with full-time all-wheel drive.
==== Milverado====
The "Milverado" was a MILCOTS (Militarized Commercial Off The Shelf) Chevrolet Silverado 2500 HD produced by General Motors for the Canadian Armed Forces. A total of 1061 units were ordered starting in the 2001 model year.
