In 1930, Gruppenführer became an SS rank and was originally bestowed upon those officers who commanded SS-Gruppen and also upon senior officers of the SS command staff. In 1932, the SS was reorganized and the SS-Gruppen were reformed into SS-Abschnitte. A Gruppenführer commanded an SS-Abschnitt while a new rank, that of Obergruppenführer, oversaw the SS-Oberabschnitte which were the largest SS units in Germany.[2]
