The Brandenburgers conducted a mixture of covert and conventional operations but became increasingly involved in ordinary infantry actions and were eventually converted into a Panzer-Grenadier Division, suffering heavy losses in Russia. Otto Skorzeny (most famed for his rescue of Benito Mussolini) conducted many special operations for Adolf Hitler. Skorzeny commanded Sonderlehrgang z.b.V. Oranienburg, Sonderverband z.b.V. Friedenthal, and SS-Jäger-Bataillon 502, 500th SS Parachute Battalion, SS-Jagdverband Mitte and all other SS commando units.
