I never met John, but his works are pretty much bible on MACV-SOG. You have to understand how rigidly compartmented covert ops have to be. You are never told anything except your own tiny little corner of things. I flew out of CCS, for example, but wasn't told that was a CCC or CCN until years later. (You might infer or assume such, but deception runs very deep even amongst the "in" crowd.) I flew missions that I couldn't discuss even with my fellow pilots at CCS, and I'm sure they did, too.
