Sgt. Thomas James Brennan (2nd L) of Randolph, Massachusetts from the 1st Battalion 8th Marines Alpha Company shouts to his comrades to keep out of the line of fire from Taliban insurgents during a firefight in the town of Nabuk in southern Afghanistan's Helmand province, November 1, 2010.

I wonder what it's like to face the next patrol after a day of close calls that leave soldiers Marines concussed and exhausted.
