You can get that by being in 11th or 12th group. They are USAR and National Guard. I would be more than happy to send you my records on active duty. If you retired from the military you have more active duty than I do. I was only active for 12 years and got caught by the RIF after Vietnam. During those 12 years, all of my assignments were in EOD, MI, or ammo plants. Most was EOD and quite active in Korea, Vietnam, and CONUS. I spent another 10 years in the USAR in ammo assignments and worked at additional ammunition plants in Civil Service. I still keep up with it. Last trip to visit my daughter in Florida I went by the school at Eglin and they took me on a tour. They have come a long way on defeating IED's.
I was always interested in explosives and munitions. I started making black powder when I was 12 years old and used to fish in my parents pond with my own version of a Dupont lure.
I did originally go in the 12th, but then shortly thereafter go active. The 12th was disbanded many years ago.
