Both Ford and General Motors produced military vehicles prior to the war, but once war was declared, Chrysler also began producing modified conventional vehicles for the war effort.

Chrysler was considered to be the leader in the field with their Dodge truck cab and suspension designs. By 1941, the Chrysler Corporation became an integral part of the Canadian family of military vehicle producers. Many of the top technical advisors provided to the Canadian government from the automotive industry during the war were Chrysler employees.
