The Wehrmacht was the unified armed forces of Nazi Germany from 1935 to 1946. It consisted of the Heer (army), the Kriegsmarine (navy) and the Luftwaffe (air force). The designation Wehrmacht for Nazi Germany's military replaced the previously used term, Reichswehr (1919–35), and constituted the Third Reich’s efforts to rearm the nation to a greater extent than the Treaty of Versailles permitted.
The Waffen-SS was created as the armed wing of the Nazi Party's Schutzstaffel (SS, "Protective Squadron"). Its military formations included men from Nazi Germany, along with volunteers and conscripts from both occupied and un-occupied lands.
