Bolshov Makar Romanovich (died 7 March 1981) was a Soviet Spetsnaz GRU operative who was assigned to ex-CIA defector Robert Aldrich's security detail in the American Southwest during the Cold War. He, Aldrich, and scores of undercover Spetsnaz operatives were killed in a shootout with a CIA Black Ops team that intercepted Aldrich's convoy on the Colorado-New Mexico border during "Operation Chaos" in 1981.
