From wiki.

Obersturmbannführer...was a paramilitary German Nazi Party (NSDAP) rank used by both the SA and the SS. It was created in May 1933 to fill the need for an additional rank above Sturmbannführer as the SA expanded...
...Adolf Eichmann was promoted to Obersturmbannführer in 1940...

How lovely to be called a Nazi in a joke thread. Thanks for that.
