Our symbolic transfer from combat during ‘Nam was when we were sent over no longer as labeled ‘combat’ but as ‘advisors’ once again.
That started just before I left CI/SERE in early 1970 and headed into country, we were given military beanies, i.e. berets, with the operations patch on them and called ‘advisors’, never did meet my supposed ‘counterpart’ the whole year I was there.
