The American capacity for mass production, shipping, and distribution was one of the major reasons why the Allies won World War II. Among the wonders to move quickly from American factories to the front lines were hundreds of thousands of jeeps. These trucks were simple to use and maintain. They could go anywhere and be adapted for multiple roles.
Stateside factories shipped jeeps in enormous crates—one per jeep. When an assembly line of trained US Army mechanics was ready, it could assemble a jeep in 3 minutes. You can read a copy of the instructions used by soldiers in 1943 at the Military Vehicle Preservation Association.
