How the character of war is changing and how militaries can successfully adapt to meet the challenge This book by military strategist Andrew F. Krepinevich, Jr., is the definitive take on the race for military dominance in the twenty-first century. It shows how militaries that successfully pursue disruptive innovation can gain a major advantage over their rivals, while those that fail to do so risk exposing their countries to great danger. The Precision Warfare Revolution introduced by the U.S. military in the First Gulf War found the United States enjoying a near monopoly in this form of warfare for several decades. But now other powers have these capabilities. The U.S. military also confronts an emerging military revolution driven by advances across a wide range of technologies--from artificial intelligence and synthetic biology to quantum computing and additive manufacturing. To stay competitive, the U.S. military must pursue disruptive innovation in a race with other militaries to exploit war's changing character. Clues exist as to the winner's identity. They are revealed by militaries that went beyond the bounds of mere innovation to overturn the existing forms of warfare, changing the course of history and the fate of nations. Through exploring their experiences, Krepinevich shows how the U.S. military can win the race to identify and exploit the "next big thing" in warfare.
