Thank you for this post.
I just called my Dad to say "Thank You". Servicemen were viewed totally different during the Vietnam era - not rearguard as heroes.
He learned a lot, became a great leader, and grew in his faith from his experience. He gives speeches at high schools about the war - he documented his experience well.
He led a platoon of 8-12 men on patrols with a M113 personnel carrier tank - His group included 7-8 tanks, including the M551 Sheridan and some others.
He manned the 50 cal on the top of the M113 tank and Dad still has BALLS OF STEEL to this day.
Thanks Dad and all the servicemen that served in Vietnam - and in any conflict. Great job Guys and Gals!
