My dad served in the USAF in the late 70's early 80's. He was between conflicts and always says that he was blessed that's how it happened.
His father was in the US Army during WWII. I don't know much about his service. I know his brother was killed during D-Day, I think it was on Utah beach. Because his brother was KIA, he was brought back to the states and did something with supplies. As a kid, I remember finding a rifle, and a belt and leather holster, with a gun in it. I didn't look inside the holster but know there was a pistol in it. It was stamped U.S. on the outside holster, and I believe was his from his time in service.
The only thing I ever remember him saying about his service was while we were at a air musuem in the late 90's. We were walking past a display case of WWII memorabilia. He stopped at the case and looked down at a tommy gun. In a soft broken voice he said, "If I had nickle for ever one of those I put in a tank.." I asked him something about it, trying to get him to talk and he didn't reply. When I looked up at him, I could tell he was trying to hold back the tears building in his eyes. His flag is folded and hung in my fathers house.
My other Grandfather served in the US Navy, Pacific theater during WWII as a radiocorpsman on the USS Breton, at some point he was in Japan, but I don't know many details. He stayed in contact with some of his shipmates till he passed in 2012. As a matter of fact, he and one of his best friends married sisters, now my grand mother and great aunt.

Out of respect for my family members, and other good friends of mine who have served, I don't wear any military stuff. The closest thing I have is a digital camo Florida State hat, given to me as a gift. Proceeds of the sale go to one of the veteran groups on campus.
On second thought, I do have an all black Army field jacket, with the button in liner. I bought it from a military surplus store before I moved away to college. It has absolutely no patches or markings. You'd be hard pressed to spot it as a military anything unless you served. Very comfortable, and very well made.
