When World War II broke out in September 1939 the US Army – starved of resources since 1919 – numbered just 174,000 men. By VJ-Day, 2 September 1945, a total of 8.3 million had served in an army which had risen to a stable strength of 91 divisions. The Army's contribution to the war against Japan – 20 divisions and numerous smaller units – has tended to be overshadowed by the exploits of the much smaller Marine Corps. This first of three titles describes the organisation, uniforms and equipment of the US Army in the CBI and the Central and South-West Pacific from 1941 to 1945.

It was the Mediterranean theatre which saw the blooding of the US Army against the German Wehrmacht, in North Africa in the winter of 1943-44 of World War II (1939-1945). After this rough education the US forces pressed on to Sicily, the South of France and the Italian mainland. Here, faced by difficult terrain, they and their British Commonwealth allies fought a long campaign until VE-Day. This second of a series of three MAA titles covers the uniforms worn on these fronts, including US Army cold weather, airborne and tankers' gear; some particularly interesting and important units, including mountain, Japanese-American and African-American troops; and a variety of crew-served weapons.

The GIs who struggled ashore through the surf of Omaha and Utah Beaches on 6 June 1944 were members of the best-equipped army ever assembled up to that date. It was in the NW Europe campaign of June 1944-May 1945 of World War II that the US Army was finally able to show its full potential for fluent mechanised warfare. This title describes both combat and service uniforms worn in the ETO, from the assault troops on the D-Day beaches to bemedalled veterans celebrating VE-Day; other subjects covered include artillery, tanks, anti-tank weapons, the engineers, the replacement system; and the insignia of the divisions committed to this front.
