Gunny was in Desert Shield, Desert Storm, and Operation Iraqi Freedom. During the battle for Fallujah, Gunny was hit in the head by an RPG, and lost his right eye. He's got a very cool prosthetic eye, although I'm sure he'd like to have his real eye back, but he's got a gold Marine Corps. eagle emblem emblazoned on that prosthesis.
Good stuff! God bless ya, Gunny. I hope to see more of you on TV soon. America needs to see more of our troops, and I couldn't think of a more cool guy to represent our military men and women than Gunny.
