Was that the Tet offensive? My dad pulled his first tour in the Delta establishing the Riverine operations and went thru the first major Tet. I pulled my duty on Hon Tre, in the Cam Rahn bay. My dad has been going to 29th reunions and is starting to talk about some of his experiences. I still have problems with talking about it. After 26 years, my wife still does not know anything about what I did other than bits and pieces.
It reminds me about the stories about Indians who visited Europe in the 1600s/1700s. When they came back, they were shunned by their tribe because tribal members could not conceive what was being described. I think over time, the 'warrior' classes have learn to be selected about what they tell to the public.
