Schutzstaffel

The Schutzstaffel (lit. Protection Squadron), also known as the SS, was a major paramilitary organisation in Nazi Germany under Adolf Hitler's rule. The SS, under Heinrich Himmler's command, was responsible for most of the atrocities committed by the Reich during World War II. After 1945, the SS was banned in Germany, along with the Nazi Party, as a criminal organisation.

In the parodies
At least some of the characters in Downfall were known to be members of the SS - that includes Otto Günsche, Hermann Fegelein, and of course, his mentor and orgnaisation head Heinrich Himmler.
