Michael R. Yunck was born on August 19, 1918 in Detroit, Michigan. After attending the University of Michigan and the U.S. Naval Academy, he enlisted in the U.S. Marine Corps as an Aviation Cadet. He completed flight training and earned his naval aviator designation in 1941. Yunck first served with Marine Observation Squadron 251 (VMO-251) in Guadalcanal (Solomon Islands), where the squadron transitioned from its initial observation role to flying fighter missions. In November 1942, he was shot down near Santa Isabel Island and spent several weeks with a coast-watcher before making his way back to base. He then joined Marine Fighting Squadron 112 (VMF-112), as most of VMO-251 had been rotated home during his absence. In 1945, Yunck took command of Marine Fighting Squadron 311 (VMF-311), flying missions out of Okinawa (Japan).

After the end of World War II, Yunck served as a test pilot at Naval Air Station Patuxent River (Maryland) and with Air Development Squadron 5 (VX-5) at Moffett Field (California). He also served as logistics officer of Marine Air Group 33 (MAG-33) during the final months of the Korean War and as operations officer of the 1st Marine Air Wing during the Vietnam War. On December 10, 1965, while flying copilot during a helicopter mission, Yunck was critically wounded by ground fire, which resulted in the amputation of his right leg. He retired as a colonel and passed away in 1984. Biographical information courtesy of: Boyce, Ward J., ed., American fighter aces album. Mesa, Ariz: American Fighter Aces Association, 1996.
