But it's hard to see these movies because they are not really distributed everywhere or when they are, it's very short moment and if you don't get them then...well that's it.
It is now available and places like amazon.com will also be distributing it soon:
Some comments, having watches the first half:
The opening minutes where the Humvee is hit while the camera is filming inside, is outstanding.
It was interesting to see the range at which engagements take place, and the weapons used, such as grenade launchers, A-10 airstrikes. I found it hard to believe the assault rifles had any accuracy at some of the distances.
The whole outpost scenario reminds of footage of similar U.S. outposts in Vietnam.
Red-dyed beards of the Afghan village elders is something to behold

Sebastian Junger has also written a book documenting the film - called "War".
