Punk said:a good fictional series about Vietnam is Rolling Thunder, Steel Tiger, Phantom Leader by Mark Berent who had three tours in Vietnam as an AF pilot, very detailed, very realistic, excellent series
I actually really enjoy bookx about the Vietnam War. Some of my favorites have been those written by SEALs..ie "The Element of Surprise", "Death in the Jungle"...Really puts into persepective just how well trained those guys really are.
