Similarly, operational design is expanded from one to four chapters to provide a more thorough step-by-step guide through the process. New chapters in this second edition include “Integrating the Instruments of Power,” “The Spectrum of Conflict and Range of Military Operations,” and “The Nuclear Weapons Triad and Missile Defense.” ’s contributing authors and editors include both military practitioners and scholars of security studies, political science, and history. In addition to being required reading for US Air Force cadets, the book provides an essential overview of strategy and practice for anyone interested in modern airpower.
