Actually, my feeling is that it's none of your business but:
For me only a short, six week experience in coastal areas off Vietnam
early in my Navy adventure. Left due to an injury that although minor
(and not fully documented as to how), still required medical attention
not readily available and was eventually transferred back to the states.
No Harry. It was not "self inflicted". :-)
Certainly not a "combat vet" nor do I consider myself a Vietnam Vet even
though my service records document Vietnam service. Compared to others I
never felt I was there long enough nor did I experience what others
(like my Hospital Corpsman buddy) experienced. He disagrees but I have
too much respect for those who had to spend full tours there.
I never wanted to be thought of as another John Kerry so to me it was
no big deal.
