Not give too much away, I think the point of the film was just to show war's effect on the individual, and how much of a life changing experience it all is, even if you're not involved in heavy combat the whole time, and even if you're not out in the trenches for very long.

After that ending montage, it made me feel empty and all I could do was think about how many people are in Iraq right now going through the same shit for no good reason. It kinda makes me sick to think about it.
