A little bitter Gepard? You are right about VietCong and NVA but, to most Americans at that time in our history they were seen to be the same and to many still are commies, the enemy, the bad guys, allies to the Soviet Union. I am not saying that myself that was just the belief of most US citizens especially at the start of the conflict. I feel the Vietnam conflict was a wast of money, resources, and most of all Humane life on all sides. Talking to many vets from that era at the local VFW Hall some, not all are remorseful for what happened it was a political puppet war w/Russia. This was a topic I started to get people thinking about the Cold War and how hot it really was. We all know that the Russians had pilots flying in N. Korea during that war, and during the War of Attrition, five Soviet-piloted Egyptian MiG-21s were downed by Israeli Mirage III and F-4 Phantoms. 
  
More thought provoking stuff: 
  
" An F-105 Thud pilot, Jack Broughton, was the author of the book Thud Ridge, where he saw a VPAF F-6 (Chinese MiG-19 Farmer clone) flown by a Soviet pilot. He looked up close and personal with the pilot and saw his blond hair and blue eyes. It was obvious that he was a Soviet." 
  
"No one really knows who "Colonel Tomb" or "Toon" was. He certainly did not have 13 AA kills as was originally believed. Nguyen Van Coc is the VNAF's highest scoring ace, with 9 claimed, and 7 U.S. confirmed AA victories. Van Coc did survive the war.there were NO VPAF pilots ranked Colonel in 1972 "Tomb" nor "Toon" does NOT exist in the Vietnamese language. The closest name that comes close to resemblance is "Tuan"  
Either Steve Ritchie or Randy Cunningham who publicly stated "I don't believe every pilot we faced in Vietnam had tan skin, slanted brown eyes, and black hair..." 
  
  
 When a pilot out flies his advasary forcing him to prang the ground and crash because he got behind on his S.A. Shoot him down with a missle or pepper his plane with bullets till he bails out or blows up, or even running him out of gas so he has to leave the plane,............You can call me a strange American but, all are kills in my book.  
Or shame on the strange American F-4 crew for attacking an enemy plane that was on a training mission.
