Georgii Samoilovich Isserson (1898-1976) was one of the most prescient and prolific authors on military art in the years preceding World War II. His theories greatly influenced the Red Army's conduct of operations and were instrumental in achieving victory over Germany. This book gathers together for the first time English translations of Isserson's most influential works, including some that are still classified. His writings on the preparation and conduct of the deep offensive operation--the deployment of tanks, mechanized infantry, air power and airborne troops to penetrate deeply echeloned defenses--also serve as a primer on how to construct a position to defeat such an attack. His well argued defense of the deep operation based on an examination of recent wars and his reminiscences about the people and events that shaped Soviet military theory in the 1930s are included.
