Invisible Armies: An Epic History of Guerrilla Warfare from Ancient Times to the Present offers the most comprehensive history of guerrilla warfare and terrorism to date. From the ancient city-states of Mesopotamia to present-day Iraq and Afghanistan, Max Boot guides readers through five thousand years of low-intensity conflict. Through a combination of deft storytelling and colorful portraits—from the iconic figures of Mao Zedong and Che Guevara to lesser-known but equally fascinating characters such as Orde Wingate and Edward Lansdale—Boot brings the history of insurgency and counterinsurgency to life as never before. Along the way, he turns conventional wisdom on its head: Contrary to popular belief, irregular warfare has been the norm over the ages; so-called conventional conflicts between uniformed, national militaries are the anomaly. Boot also explicitly relates history lessons to current national security policy considerations, lending the book contemporary significance for soldiers, students, policymakers, and the general public.
