Major Nguyễn Văn Nhung (1919 or 1920 – 31 January 1964) was an officer in the Army of the Republic of Vietnam (ARVN). After joining the French Army in 1944 during the colonial era of Vietnam, he soon met and became the aide-de-camp and bodyguard of Dương Văn Minh, and spent the rest of his career in this role as Minh rose up the ranks to become a general. Nhung and Minh later transferred to the French-backed Vietnamese National Army (VNA) during the First Indochina War and he became an officer; the VNA then became the ARVN after the creation of the Republic of Vietnam (South Vietnam). A soft-spoken man, Nhung was a professional military hitman who was reputed to have etched a line on his revolver for each of his killings, and ended the lives of 50 people during his career.
