Depends on what you are looking for I suppose. If you want accurate reference I would agree. Rambo I was a good movie though and stands the test of time. Rambo II was watchable and Rambo III was totally unbelievable as far as entertainment goes.
I bought cross of iron recently and enjoyed the film and had about 50 shots of inspiration for making dios. Same with Blackhawk down. Havent a clue how accurate any of them are though. Hard to beat Kelly´s heros. I know those tigers are not accurate but still a great movie.
Delta force were great.......... 20 years ago, but didnt stand the test of time.... the acting is terrible and have never heard of Rangers. I´ll take your word for that one sabot!
