Siegfried Müller

Siegfried Müller (1920–1983) was a German Wehrmacht officer-candidate who served in World War II and later became a notorious mercenary known as 'Kongo' Müller for his brutal actions in the Congo Crisis. He earned a fearsome reputation as a talented soldier and murderer during mercenary operations in Africa. After the war, he fought in conflicts including attempts in the early 1960s that led to defection.
