Grenada was in October, 83 and only the US 82nd Airborne, 75th Rangers and US Marines were at Grenada. Those units will be in country soon, but I doubt any Grenada veterans PCS'd from these units to 2nd AD (Forward). PCS: Permanent Change of Station.

When I was with 2-36 IN (M), 3rd AD in 84, my supply sergeant had served a tour with the 4th ID and one with the 101st Airborne in Vietnam. My Battalion Commander was with the 1st Cavalry Division as a Platoon Leader. To be a Vietnam "era" veteran and be in the Army in 1983, at a minimum, the soldier would be 26 years old and that marks 1975 as the last year of the war. More than likely they are older. Most Vietnam veterans left the military and by 1972 - 75, they were downsizing quite a bit. 67 - 72 was the height of the war. More than likely, your veteran served during that time period.

Since we are chatting about this, I am considering working on the 3rd Brigade, 2nd AD Brigade Commander. I could use this character to collaborate with Rare. The FSB Commander essentially runs the Brigade Support Area, or at least his portion of it (75%) and works closely with the Brigade's Supply Officer (S4). I could make up a CS for the Brigade Commander and then use the S4 and S1 and NPCs. The Brigade Commander will definitely be a Vietnam Vet and be an old fart.
