I watched this the other night. Hadn't seen it it ten years or so. It's still a pretty good movie. The thing that surprised me is it didn't seem as brutal as it once did. I'm thinking that because of how often brutality is shown on the news it just doesn't seem that shocking anymore.
My dad likes FMJ right up until the point where they graduate boot camp and go to Vietnam. He says it's damn accurate up until that point.
