Unfortunately, Hollywood seems to think that there has to be something for the non-history buff too often. So we have to put up with it. I can not personally attest to most but if you are interested in reasonably accurate films of Vietnam "Hamburger Hill" gives a good picture of the typical life in an infantry platoon (I was a grunt then). While it is not history (although the May, 1969 battle for Hill 937 was real and we went back in 1970), it does a very good job showing that life in that time. Also "We were soldiers once" is a good and realistic portrait of 1965 in Vietnam. Sam Elliot had the character of that era of senior NCO's down pat.
