What an interesting thread! It's great to see so much diversity and fascinating stories. I even see a few names I'm familiar with, so it appears we share even more than just an interest in aviation.
I'm an Army Vet, 21 years shooting mortars with about 20 of them actually hitting the target

First combat was as a PFC with Aco 1-508 PIR, 82nd Airborne, during Operation Urgent Fury in Grenada, Oct 27, 1983. It was our first major offensive action since Vietnam. In fact, many of our senior NCO's and Officers were Vietnam Veterans, so it was an honor to have 'the torch' passed directly from their hands. And speaking of history, General James Gavin, the 82nd's commander in WWII, was the guest speaker at our Division Review that year.
Later I went to 1-67 Armor, 2nd Armor Division, at Ft Hood TX, and did REFORGER '85 & '87. Talk about a square peg in a round hole.. Mortarmen are probably the only Infantrymen you'll ever see assigned to a armor unit, since they still need us to shoot smoke screens and take out observer and AT positions, etc. Was fun to see the big M-1's in action though.. plus it was nice knowing there were a few Abrams on point. I totally fell in love with Europe during the REFORGER tours. Got to visit the memorial at Bastogne, which was quite a moving experience.
Spent '88 -'89 with Aco 2-503rd Infantry (Light), 2nd ID, at Camp Hovey, ROK, including a DMZ tour, and a train ride to Seoul for the Olympics. Many places still exhibited the scars of the war.. crater-etched trench and bunker complexes, range fans still painted on the parrapets of MG positions, schrapnel lodged in tree trunks, etc. Probably got into the best physical condition of my life there, thanks to all the cross-country marches over the steep terrain; came home feeling like Superman. My Dad spent the entire war in Korea, until being wounded for the last time at Porkchop Hill during a bayonet assault. He was a combat medic with the 32nd Infantry Regiment, 7th Infantry Division, and was awarded three Purple Hearts and the Bronze Star with 'V' device.
Next came Ft Stewart, GA, assigned to 3-7 Infantry (Mech), 24th ID. Served in Desert Shield/Storm under the excellent leadership of General Barry McCaffery, who led us deep into Iraq and got us home again (well, most of us).
Then went to Vilseck, GER, on the south side of Graffenwoehr, assigned to 3rd Infantry Divison and was later reflagged to 1st Infantry Division. Took charge of my first platoon there; what a great bunch of soldiers, I'm still proud of 'em. Visited Berchtesgaden and the Eagle's Nest, Cologne Cathedral (my wife's hometown), Paris, Venice, Salzburg, Pilsen, and several historical sites that I would likely never had seen if not for military service.
Seven years and nine Hohenfels rotations later, I ended up in Ft Carson, CO, with 1-12 Infantry, 4th ID, and made a few trips to Kuwait.
Called it a day in 2004 and retired, although I'm still fortunate to work closely with our active duty soldiers on a daily basis.
Seen a fair share of horrible stuff, a few incidents of downright spooky stuff, and wore out a few parts; but I'd have to say most of my experiences were times I wouldn't trade for all the riches in the world. I had the privilage to serve alongside some truly outstanding soldiers and meet some of the finest folks you'd ever want to know, and not only from the US Army.. and that's why I'm really enjoying this thread; it's great to hear from members of the same fraternity, no matter what side of the fence we were on.
Here's to ya Mates; Salute!
