In the spring of 1945 Shadow Division Steiermark controlled two RAD brigades, and these were mobilized for combat duty as an "Alarm" division under the name Mountain Division Steiermark. The division's two regiments were composed of a very diverse mix of personnel from the Army, Luftwaffe, Kriegsmarine, Waffen-SS, police, and other organizations. It appears also to be related to Kampfgruppe Raithel and/or Kampfgruppe Semmering, though the late-war documentation is weak.
