Mtn Infantry,
I can tell you Gramps was born in 1922, he joined the Army in 1940, retired after 41 years in '81, he didn't talk much about it even though I always had ears wide open and mouth shut wanting to learn, I remember WW-II, Korea and 'Nam, he was a boot heel tough old bird, guessing a German 8mm round creased his helmet early on in WW-II, he wore a scar above his right eye from I guess the bullet powdering the bone in his forehead, just a sunken in spot. he was an E9 Sergeant Major that stayed in the chit with his men.
His dress uniform was beautiful, can tell you he had lots of hash marks down the sleeves of his coat, though I never asked what they or any of the very large panel of Medals meant, he was the kind of guy you just didn't intrude on, even if you were a grandson.
We buried him ten days before Christmas 2015 at 93 years of age
