As an ex-military person, the discrepancy of rank in this movie is very glaring to me. Chuck Palmer is an Ensign (the lowest navy officer rank), but wears silver clusters (the rank of a Lt. Commander). At one point he is talking to an army Major and mentions that, although he is in the navy, they are of the same rank (the navy equivalent of an army major is a Lieutenant). It's an interesting movie to watch when you're up at 2 am and can't sleep. But, overall, I think this is a very sanitized version of the guerrilla fight in the Philippines during World War 2. If you've just tuned into the film at some parts, you'd think you were watching a documentary. An interesting trivia note: Jack Elam is the narrator in this film, but he also has a cameo in which he plays a con artist who bilks the locals of money in order to "buy guns and ammunition to fight the Japanese".
