These unique vehicles also saw heavy service under General John J. "Blackjack" Pershing as both the Jeffery armored car and as regular transports during the Army's 1916 Punitive Expedition through Mexico; Quads were also used extensively during Pershing's later European campaigns of World War I. The United States Marine Corps also adopted the Jeffery Quad, using it in the occupation of Haiti, and of the Dominican Republic, from 1915 through 1917.
