I hope you get this off the ground may pay to have a tape recorder there, but I would certainly vett the questions you may trigger a long supressed bad moment not all vet's offer up their experiences especially those of a Sniper where they can see the whites of their eyes so to speak. (I really do hope it works and well done supporting forumers of Ian's endeavour)

I am no orphan when it comes to the lack of responses from a parent that went to WWII my dad only spoke just to my B/inlaw once about his 4 years over seas and that was I guess because my B/inlaw went to Vietnam on a holiday to try and meet Uncle Ho
