Yes, I keep getting all excited about everything I find being shot with a DSLR, but this is the most intense thing I've see so far.
Basically this guy went in with a 5D Mark II along side of Marines trying to take a Taliban run area in Afghanistan. One of the guys dies, and he apparently includes that in the doc. Very intense stuff.
I will say that reading about this three day battle makes me sad about the job these guys are being sent in to do. When you can't even tell who the bad guys are, the locals get hurt or die, and then no one wants you there in the first place.
