So if you know a vet. Just a comment on his service, might buy him a good nights sleep.
Well, I know you mo, thanx for what you did in vietnam.

(not joking)
I know a guy who was an army ranger in vietnam. He has stories to tell about some things that he did that makes my hair stand up. Stories of close in fighting and all he had was a shotgun and such (you get the picture)
I know you were an M60 machine gunner mo, and I'm sure there are lots of things you could talk about.
I've never been in the service, but I got tons of respect for guys who have served, especially ones who have served in a war.
