Taps – Maybe. Probably. Posted on April 16, 2018 by Mitch Berg R. Lee Ermey – “Gunnery Sergeant Hartmann” from the movie Full Metal Jacket, and a former USMC gunnery sergeant in real life – has passed away. Maybe. Ermey’s been the subject of numerous internet death hoaxes – but unless someone hacked his official Facebook page, this one may be legit.
