In which year was this Nazi Party paramilitary rank created that Emil Ketterer belonged?
Obergruppenführer Obergruppenführer (] , "senior group leader") was a Nazi Party paramilitary rank that was first created in 1932 as a rank of the "Sturmabteilung" (SA), and adopted by the "Schutzstaffel" (SS) one year later. Until April 1942, it was the highest commissioned SS rank, inferior only to "Reichsführer-SS" (Heinrich Himmler or RFSS, which was the internal SS-abbreviation for Himmler) Translated as "senior group leader", the rank of "Obergruppenführer" was senior to "Gruppenführer". A similarly named rank of "Untergruppenführer" existed in the SA from 1929 to 1930 and as a title until 1933. In April 1942, the new rank of "SS-Oberst-Gruppenführer" was created which was above "Obergruppenführer" and below "Reichsführer-SS".
SS-Stabsscharführer SS-Stabsscharführer was a non-commissioned officer title which was used by the Waffen-SS between the years of 1938 to 1945. "SS-Stabsscharführer" was not an actual SS rank, but rather a positional title held by the senior SS-NCO of a company, battalion, or regiment. Typically, those holding the position of "Stabsscharführer" ranked "SS-Oberscharführer" (OR-6) or "SS-Hauptscharführer" (OR-7) above.
