Here is a classic: Dead Presidents. About how these men go into the marines. serve a lot of time, get out and get nothing for their services. Has some weird stuff in it too. One guy cut off the head of a Vietmanese dude and was carrying it around as a good luck charm. I won't reveal anymore for those that might not have seen it yet, awsome movie though.
