Actor and retired US Marine R Lee Ermey – best known for his role as Gunnery Sergeant Hartman in Stanley Kubrick's Full Metal Jacket – has died, his manager has said.
The 74-year-old died from pneumonia-related complications on Sunday morning, Bill Rogin said.
"It is with deep sadness that I regret to inform you all that R. Lee Ermey ("The Gunny") passed away this morning from complications of pneumonia," Mr Rogin tweeted.
"He will be greatly missed by all of us. Semper Fi, Gunny. Godspeed," he added, referencing the motto of the US Marines Corps, in which Ermey served from 1961 to 1971 when he was medically discharged.
Born in Kansas in 1944, Ermey gained his first acting role while studying drama at the University of Manila in the Philippines, landing a part as a helicopter pilot in the 1979 classic Apocalypse Now.
He went on to appear in some 60 films, often in military-related roles, and was nominated for a Golden Globe Award for his performance in Full Metal Jacket.

Ermey also voiced the little green army man Sarge in the Toy Story films and hosted several weapons-related TV shows including the History Channel's Lock n' Load With R Lee Ermey.
His manager said that while his characters were often hard-nosed and principled, the real Ermey was a family man and "a kind and gentle soul".
