Because they saw me most of the time in combat camouflages, not in "Olive Drab",
my friends didn't believe that I was an actual soldier.

I was!
In this picture with full uniform and my military unit insignia,
you can tell I was a member of the ARVN's
10th Politic Warefare Battalion, APO 3463
stationed at Thanh Son Street, Danang City, Vietnam.
