Is there a way to verify a person was a member of the UN Peacekeepers?

No it is impossible. You could be in the Reserves and never leave Kansas and you still have VA benefits to include VA loans for housing. Health benefits generally don’t kick in for anyone unless the issue was service related or you retired the military. Even most discharges that are less than honorable will not make you lose all of your benefits.

If you want real answers PM me and I can point you to several places that investigate phony claims.

Maybe, but the issue was the believability of the OP’s storyteller. I was responding to someone who said no because individuals never serve. I was merely disputing that that alone was grounds to reject the story. It’s not, as my brother’s example showed. I still think the OP’s friend is full of shit.
