Introduced in 1953 as the M170 military version, the civilian CJ-6 made its debut in 1955 as a 1956 model. Never very popular in the United States, most CJ-6 models were sold to Sweden and South America.  

 The M170 military version shared many of the features of the M38A1 (Military CJ-5), but had the passenger-door opening extended back to the rear wheel well. Most were used as front-line field ambulances, able to carry four litters. A few were also used as radio units.
