In the German Wehrmacht a General of a branch (German: General der Waffengattung) was linked to service arms of the Heer (army) and Luftwaffe (air force), depending on where the officer served and what troops he (nominally) commanded. It was equivalent to the three-star ranks of admiral in the Nazi Kriegsmarine, and SS-Obergruppenführer und General der Waffen-SS in the Waffen-SS. A commander-in-chief (Kommandierender General or Befehlshaber) of a German army corps was usually of this rank.
