“During the first nineteen months of its participation in World War II, the U.S. Army purchased almost 950,000 trucks, nineteen times the number it had procured during the corresponding period of World War I. From Pearl Harbor to V-J Day it procured for its own and Allied forces some 84,000 tanks, 2.2 million trucks, 6.2 million rifles, 350,000 artillery pieces, .5 billion rounds of ground artillery ammunition, 41 billion rounds of small arms ammunition. It shipped overseas 127 million measurement tons of cargo, and 7.3 million troops and other passengers.” – Richard M. Leighton and Robert W. Coakley, Global Logistics and Strategy: 1940-1943
