Book excerpt: This landmark study, first published by Cornell University Press in 1966, shows how Hitler's elite army grew from a praetorian guard of barely 28,000 men at the beginning of the Second World War to a combat-hardened army of more than 500,000 in 1945. George H. Stein examines in detail the structure and organization of the Waffen SS and describes the rigid personnel selection and intensive physical, military, and ideological training that helped to create the tough and dedicated cadre around which the larger force of the later war years was built.
