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 nature of war is constant change. We live in an era of exponential technological acceleration which is transforming how wars are waged. Today, the battlespace is transparent; multi-domain sensors can see anything, and long-range precision fire can target everything that is observed. Autonomous weapons can be unleashed into the battlespace and attack any target from above, hitting the weakest point of tanks and armored vehicles. The velocity of war is hyper-fast.

What happens to the US Army after the battles are over, the citizen soldiers depart, and all that remains is the Regular Army? In this pathbreaking work, Brian Linn argues that in each decade following every major conflict since the War of 1812 the postwar army has undergone a long, painful, and remarkably consistent recovery process as it struggled to build a new model force to replace the "Old Army" that entered the conflict.

World War II is usually seen as a titanic land battle, decided by mass armies, most importantly those on the Eastern Front. Phillips Payson O'Brien shows us the war in a completely different light. In this compelling new history of the Allied path to victory, he argues that in terms of production, technology, and economic power, the war was far more a contest of air and sea than of land supremacy.

Just a few years ago, people spoke of the US as a hyperpower—a titan stalking the world stage with more relative power than any empire in history. Yet as early as 1993, CIA director James Woolsey pointed out that although Western powers had "slain a large dragon" by defeating the Soviet Union in the Cold War, they now faced a "variety of poisonous snakes." In The Dragons and the Snakes, the eminent soldier-scholar David Kilcullen asks how, and what, opponents of the West have learned during the last quarter-century of conflict.
