On Operational Art, a companion volume to Michael D. Krause's and R. Cody Phillips's Historical Perspectives of the Operational Art, captures the doctrinal debate over the concept of operational art. Edited by Clayton R. Newell and Michael D. Krause, the well-organized anthology presents a snapshot of the development of operational art when the Army's attention was focused on Europe and the Soviet Union. Consisting of original essays by distinguished historians and senior military commanders, to include a prominent German officer, the collection has not only a joint and combined flavor but also a tactical and strategic dimension. Reflecting contemporary thoughts on new developments in U.S. military doctrine and covering significant battles and campaigns from the past, On Operational Art is invaluable as a frame of reference for understanding the operational level of war from the insightful commentary on the various aspects of practical application. Those interested in the theory of war will find it useful for studying the evolution of doctrine from theory into practice.
