SS-Oberst-Gruppenführer () was (from 1942 to 1945) the highest commissioned rank in the Schutzstaffel (SS), with the exception of Reichsführer-SS, which became a commissioned rank when held by SS commander Heinrich Himmler. The rank is translated as "highest group leader" and alternatively as "colonel group leader". The rank was correctly spelled Oberst-Gruppenführer to avoid confusion with the more junior rank of Obergruppenführer. Overview Oberst-Gruppenführer was considered the equivalent of a colonel general (Generaloberst) in the German Army, which is generally seen as the equivalent of a four-star general or army general in other armed forces.

On the same day orders were issued for a dual promotion within the Ordnungspolizei, making Kurt Daluege a Generaloberst der Polizei at the same time. Daluege's rank was the only police promotion to this rank. The last two of the four Oberst-Gruppenführer promotions were made in 1944, this time to Waffen-SS generals. Dietrich's date of rank was back-dated to 1942, making him the most senior officer of the Waffen-SS. The final seniority list was as follows: Franz Xaver Schwarz, 20 April 1942 (... der Allgemeinen SS) Josef "Sepp" Dietrich, 20 April 1942 (... und Panzer-Generaloberst der Waffen-SS) Kurt Daluege, 20 April 1942 (... und Generaloberst der Polizei) Paul Hausser, 1 August 1944 (... und Generaloberst der Waffen-SS) Franz Xaver Schwarz, who held Ehrenführer (honorary leader), was the only holder of the rank who was not granted equivalent police or Waffen-SS rank.
