The jeep became the primary light wheeled transport vehicle of the United States military and its allies, with President Eisenhower once calling it "one of three decisive weapons the U.S. had during WWII. It was the world's first mass-produced four-wheel drive car; almost 650,000 units were built, constituting a quarter of the total U.S. non-combat motor vehicles produced during the war, and almost two-thirds of the 988,000 light 4WD vehicles produced, counted together with the Dodge WC series. Large numbers of jeeps were provided to U.S. allies, including Soviet Union at the time — aside from large amounts of 11⁄2- and 21⁄2-ton trucks, some 50,000 1⁄4-ton jeeps and 25,000 3⁄4-ton Dodges were shipped to Russia during WWII — more than Nazi Germany's combined total production of their best performing similar vehicles, the Kübelwagen and the amphibious Schwimmwagen.
