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".
