I am unaware of specific programs (does not mean they did not exist), but you must remember people were much more reliant on EACH-OTHER rather than some kind of government/ third party program back then; community was a much larger part of the picture. There were many reunions after the war where they would talk though their experiences with the ones they went through it with, even companies had their own 'mini' reunions starting in 46. The 82nd's association actually started right after the Battle of the Bulge before the war even ended. Perhaps some of the WWII vets on the forum can chip in?
On the last disc, it says what they did after the war. Normal things. If you approach a vet the right way, they will talk about anything. Trust me. Most mistakes people make in trying to get them to talk about it is this: they (the vet) DOESN'T want to have an informal conversation about it. Sit them down, get the pen and paper out, and have a long conversation giving them your undivided attention and have true interest in what happened. It has worked for me and my buddy.
