The books I have cover the whole spectrum of the war. From the grunts on the ground, sea or air. To an overview of an operation as seen from the higher ups. My wife’s brother in law who was in some serious battles in Afghanistan, is in the book “The Chosen Few”.
A retired coworker wrote the book “From Mokane To Molehill”. He was in Vietnam.
As for the movies, most are just a movie made to get folks attention. There are a few movies that do show the events pretty accurate.
