I just finished reading the most informative,gut wrenching,true accounts of our service men mainly the US Navy and Army. "Fire from the sky" is the history of Helicopter Light Attack Squadron 3 in Vietnam. I could not put this book down. I got it on Amazon. I had a friend who flew with them and the account of his being KIA in 1969 was in one chapter.I did not realize the "Huey" helo was that tough of a bird. The sailors who flew were so dedicated and thier accounts are gut wrenching. If you can get hold of this book and read it you will be impressed believe me.
