I've met some interesting vets as well. The first was a member of the 1st Infantry Division in the ETO. One of the main things I recall about speaking to him was his response when asked if he had ever ran into any SS troops - he frowned and said something to the effect of "Anybody with lightning on their collars we shot. We didn't take any of them prisoner". WOW! For those of you guys who aren't real familiar with this stuff, SS troops wore SS runes on their collars which basically looked like 2 lightning bolts.
The second guy I can recall was born in Poland and drafted into the Russian (!) army after the Russians occupied the part of Poland he grew up in. He served in some sort of sanitation unit, who's job it was to clean up the mess after a battle. This included burying bodies, gathering remains from all over the place, etc. He was in quite a few tight spots. I do remember him mentioning being in Kharkov during the battle that took place there.
Whenever I deal with an older person who might be of that age group I always make it a point to ask what they did in the war. I think they appreciate other people showing genuine interest in the most significant part of their lives. The stories you occaisionally get can be fascinating.
