U.S. Army Special Operations in World War II fills a gap in the Army's record of its overseas activities. As David W. Hogan so clearly states, a variety of commando and guerrilla operations were conducted on the plains of Europe and in the jungles of the Pacific to harass the Axis armies, to gather intelligence, and to support the more conventional Allied military efforts, yet their significance was a matter of dispute. Hogan examines the critical issues underlying special operations and shows how American leaders employed commandos-rangers in Army parlance-and guerrillas extensively, if not systematically, during the war. An important overview of the Army's past experience, the study contains useful lessons at a time of keen interest in the critical role being played by special operation forces in meeting today's contingencies.
