The Diamond T Motor Car Company became one of the U.S. Army's official suppliers in the mid-1930s. And so in 1940, with war looming, orders for Diamond T's brand-new 6×6, 4-ton trucks began rolling in: some 36,500 of the various versions would be supplied between November 1940 and August 1945. During the war years Diamond T would go on to deliver more than 50,000 vehicles to the U.S. Army and its allies, of which over 30,000 were heavy 4-ton, 6×6 trucks. The "Diamond" was present in all theaters of operation.

Because of its expertise in producing heavy-duty vehicles, Diamond T also manufactured the famous halftrack, with more than 10,000 examples produced. This comprehensive and fully illustrated account describes in technical detail the evolution of the Diamond T design, and all the Diamond T models produced for the Army during World War II, including wrecker trucks, pontoon trucks, dump trucks, halftracks, and prime mover trucks.
