a a nam vet and former combat infantry squad leader i can tell you this movie be 80 % b . a comment on by others we do not build permanent camp in the middle of the jungle . camp be build in area where clear field of fire can be create so that daylight surprise attack like the one depict in the movie can not happen . there also be no jeep rid down two track in the jungle and for the same obvious reason . there be so many factual error in this flick like uni and incorrect armament and a unit insignia that i have never see before and etc and etc and etc . the director obviously have no knowledge of what go on in vietnam and he do not bother to find out by bring in a knowledgeable technical consultant . this movie be without question the bad vietnam era movie ever make and one of the bad war movie of all time . the shame of it be that there be a truly gripping story to be tell about guy who volunteer to be tunnel rat in the nam and this flick fail miserably to tell that story . what bad be from what i see on this website and far too many of you think this be some kind of representative and half way decent movie . nothing could be far from the truth . and fyi and there be no 6 foot and 6 foot plus tunnel rat a depict in the movie . tunnel rat by necessity be the short guy who more approximate the size of the people who build and use the tunnel .
