Book excerpt: An extensive guide to Japan’s Army Air Force Units and their ace pilots during conflicts in the 1930s and ‘40s, now in English. Commencing with a detailed study of the development, equipment, and operations flown by this force since its inception immediately after the end of World War I, until the catastrophic conclusion of World War II, the initial section deals with the wars in China and Manchuria, as well as the Pacific War of 1941-1945. The second section explores the history of each unit, listing the types of aircraft used, the bases from which they flew, and the unit and formation commanders. Notable mission details are also included. Finally, the third section offers biographical notes for notable fighter pilots and features supporting listings and a glossary of Japanese terms. Photographs of pilots and aircraft are also included, along with line drawings indicating the unit markings carried. This revised edition is a companion volume to Japanese Naval Air Force Fighter Units and Their Aces, 1932–1945.
