this film be base on true event and if the u soldier be a badly train and stupid a this outfit be portray and then it a wonder they do not lose the war sooner . for example and we see two soldier stand over a hole while comrade be below and these two soldier see the vc come . do they find cover from which to fight behind . nope one stand up swing a big machine gun one hand arnie style shout at them . they have a camp in the middle of the jungle and the vc attack and right from the first tent . how on earth would they have get that close to a base camp . no fence or guard on duty that day . please . then the co call for immediate air support a they be be over run and be over run would have be more like it . the immediate air support do not turn up until later when everybody have go home and have they fly all the way from america . you felt absolutely no sympathy with the character and we have just about every clichéd character you could think of except the chirpy cockney and the scouse scallywag . they try to build background and personality to the character but fail miserably and maybe because it be do very lazily and ie have two actor discuss all the character for our benefit while they eat . the conversation just doesn not seem real . it be a shame because the film start well and the scene in the tunnel involve the mother and kid be genuinely tense but it seem so out of place with the rest of the film which be and badly act to say the least . i seem to remember the excellent tour of duty tv series cover this subject in one episode and they manage to fit in more tension and understanding of these terrify tunnel in a fifty minute programme than this film manage . i just keep think that 1968 tunnel rat be like a bad horror film where the goody ( in this case the tunnel rat ) be be pick off one by one by the evil monster ( the vc ) in different and more nasty way and the only mystery be who be the one that be go to survive . be it the guy that believe god will protect him . the co that be nasty to his men a a way of protect them and prepare them for the nasties of war etc .
