This volume in the Praeger Security International (PSI) series "Classics of the Counterinsurgency Era" defines the laws of insurgency and outlines the strategy and tactics to combat such threats. Drawn from the observations of a French officer, David Galula, who witnessed guerrilla warfare on three continents, the book remains relevant today as American policymakers, military analysts, and members of the public look to the counterinsurgency era of the 1960s for lessons to apply to the current situation in Iraq and Afghanistan. With a new foreword by John A. Nagl, author of Counterinsurgency Lessons from Malaya and Vietnam (Praeger, 2002).
