If you liked BHD as a movie, you need to read the book. There are many things in the book that you won't get from the movie, although yes, I loved the movie.
In the book (at the end) the author talks about interviewing many of the survivors. Most had one thing in common - they were mad. Not mad because they had to go fight..
They were pissed because Klinton wouldn't let them go back in to kick some more ass.
Awesome men, all of them. They have my utmost respect.
