The Jeffery Quad, and from the company's take-over by Nash Motors after 1916, the "Nash" Quad truck, greatly assisted the World War I efforts of several Allied nations, particularly the French. The United States Marine Corps first adopted Quads in anger in the U.S. occupation of Haiti, and of the Dominican Republic, from 1915 through 1917. The U.S. Army's first heavy usage of Quads was under general John "Blackjack" Pershing in the 1916 Pancho Villa Expedition in Mexico — both as regular transport trucks, and in the form of the Jeffery armored car. Once the U.S.A. entered World War I, Nash Quads were used heavily in Pershing's subsequent campaigns in Europe, and they became the workhorse of the Allied Expeditionary Force there. Some 11,500 Jeffery / Nash Quads were built between 1913 and 1919.
