The Wehrmacht (literally "defense force") was the name of the unified armed forces of Germany from 1935 to 1945. It consisted of the Wehrmacht Heer (army), the Kriegsmarine (navy) and the Luftwaffe (air force). The Waffen-SS, an initially small paramilitary section of Heinrich Himmler's Allgemeine SS that grew to nearly a million strong during World War II, was not officially part of the Wehrmacht, but subject to OKW, OKH, as well as Field Command. Thus, the Waffen-SS was, de facto, a fourth branch of the Wehrmacht.
