Siegfried Müller (mercenary)

Siegfried Friedrich Heinrich Müller (26 October 1920 – 17 April 1983), referred to as "Congo Müller" (''Kongo-Müller''), was a German-born soldier and mercenary. Müller served as an officer-candidate in the ''Wehrmacht'' in World War II and, after emigrating to Apartheid South Africa, became a mercenary commanding part of 5 Commando in the Congo Crisis.

Given substantial media attention by foreign journalists in the Congo, Müller achieved widespread notoriety in West and East Germany in the mid-1960s as a result of war crimes and overt nostalgia for the Nazi era, including his affectation of prominently wearing his Iron Cross. Due to his controversial actions in the continent he became a particularly unsavory character in common's people view of the work of European mercenaries in African conflicts. Provided by Wikipedia
