Biography
Ronald Lee Ermey, widely known as R. Lee Ermey, was born on March 24, 1944 in Emporia, Kansas. His early years were marked by a rebellious streak; he reportedly got into frequent trouble as a teenager, leading his mother to seek the intervention of a judge. At age 17, Ermey faced a choice between jail and military service—he chose the latter, marking the beginning of a life deeply influenced by the United States Marine Corps.
Enlisting in the Marine Corps in 1961, Ermey underwent recruit training at the Marine Corps Recruit Depot in San Diego, California. He initially served in aviation support before becoming a drill instructor for India Company, 3rd Recruit Training Battalion at the same depot from 1965 to 1967. Ermey was later stationed with Marine Wing Support Group 17 in Okinawa, Japan, and spent 14 months in Vietnam during the height of the conflict. He rose to the rank of Staff Sergeant (E-6) before being medically retired in 1972 due to injuries sustained during his service. His contributions to the Corps were later recognized with an honorary promotion to Gunnery Sergeant (E-7) in 2002—the first time a retired Marine was so honored.
After his discharge, Ermey relocated to the Philippines, where he studied criminology and drama at the University of Manila. His military experience helped him land roles in several Filipino films and as a technical adviser (and actor) for Hollywood’s Apocalypse Now (1979). His big break, however, came when he was cast as the iconic Gunnery Sergeant Hartman in Stanley Kubrick’s Full Metal Jacket (1987). Originally hired as a technical advisor, Ermey’s on-set improvisations earned him the role itself, and his portrayal garnered widespread acclaim and a Golden Globe nomination for Best Supporting Actor.
Ermey was frequently cast in authoritative roles—mayors, police captains, military leaders—in films such as Mississippi Burning, Se7en, and Dead Man Walking. He also became a beloved voice actor, famously portraying “Sarge” in all three Toy Story films and lending his voice to numerous animated series. On television, he hosted History Channel’s Mail Call and Lock ’N Load with R. Lee Ermey, exploring military history and the evolution of weaponry.
Beyond show business, Ermey was a dedicated supporter of the military and veteran communities. He regularly visited Marine Corps boot camps, spoke at military events, and participated in charitable activities supporting both active-duty service members and veterans. He was also involved with organizations like Toys for Tots and made several trips to visit U.S. troops overseas.
R. Lee Ermey married Nila Ermey in 1975, with whom he had four children. He passed away on April 15, 2018 in Santa Monica, California, from complications related to pneumonia at the age of 74. He is remembered not only for his commanding screen presence but also for his steadfast advocacy for those who serve in the armed forces.
