This immediately reminded me of my late father-in-law who fought in Korea. He spent eight years in the Marine Corps and to hear him tell it, he spent most of his hours in those eight years cleaning his rifle. He used to say that when he was in the Marines, he dreamed of the day he got out so he could buy an M1, leave it in the backyard, pee on it every day and watch it rust. I don't think he was serious. He was very fond of the M1 (the M14, not so much) and proud of Marine Corps marksmanship in general.
