US Army '87 to '95, Supply Sergeant, Ft Hood and Ft Benning with a couple trips to Iraq in the middle
27 Years with the Canadian Forces. Recently retired from the active forces and working for the DND 'til official retirement. My Father served with the RCAF for 15 years and My Grandfather(RIP) served with the Royal Newfoundland Regiment in WW I and WW II. He was wounded in action, although I can't find anymore info on him.
What were you in? I was RCEME for 13 years. Just to let you know that you can contact Veterans Affairs and they will send you a form in which you should be able to get the info on your Grandfather. He was sure lucky during WW1 as not many of that regiment made it home, thanks to Butcher Haig (British General).
