General S.D. Rockenbach, Patton's commanding officer and Chief of the A.E.F. Tanks Corps, and Major Sereno Brett, a tank expert in his own right, also provide important accounts. After the war, the U.S. Army continued to experiment with tanks and debate their appropriate role within the military. I to the eve of World War II, document the evolution of tank development. Various tank models, including British, French, German, Swedish and Italian, as well as American, models are depicted. The tanks are shown both idle and being operated in war games and other experimental tests.
Textual records complement the photographs and bring many contemporary issues to light.
Such questions weighed heavily on the minds of Army officials, as revealed through reports, War College lectures, newspapers and correspondence. An interesting piece of correspondence to Major Sereno Brett in 1930 argues against the formation of a proposed Army Tank Division. This is, in effect, an army corps. Something about half this size seems more reasonable. The greater the mobility the greater the difficulty to control.
