I don't know why, something just made me think of that.The Schutzstaffel (Protective Squadron), or SS, was a large paramilitary organization that belonged to the Nazi party. The SS was led by Heinrich Himmler from 1929 until it was disbanded in 1945 with the defeat of Germany in World War II. The Nazis regarded the SS as an elite unit, a Party's "praetorian guard", with all SS personnel selected on racial and ideological grounds. The SS was distinguished from the German military, Nazi Party, and German state officials by their own SS ranks, SS unit insignia, and SS uniforms.
The SS fighting units, called the Waffen-SS, were to evolve into highly skilled and effective soldiers, in many cases superior in these respects to the German army, the Heer.
The most recognizable branches of the SS, later charged with war crimes and crimes against humanity, were the departments that comprised the Reichssicherheitshauptamt (RSHA, Reich Security Head Office), Sicherheitsdienst (SD, Security Service), Einsatzgruppen (Special Mission Groups), the concentration camp service known as the SS-Totenkopfverbände (SS-TV, Death's Head Formations), and the Gestapo (Secret State Police).
