An inside look at the 'Troop surge'.

Smith spent two weeks with members of Apache Company and filmed them as they went on daily routine investigations, including one of a bomb making factory hidden in a private home. Soon after they arrived an explosion hit and an Iraqi soldier and several neighbors, including children, were hit.

"I challenge anybody in Congress to do my rotation," said Spc. Michael Vassell of Apache Company. "They don't have to do anything, they just come hang out with me and go home at the times I go home, and come stay here 15 months with me."

"It's a joke. We will have spent 14 months in contact, basically fighting all 14 months," said Cpl. Joshua Lake. "Our battalion got right to Baghdad … first week we were in Baghdad we lost two guys in our battalion … it hasn't stopped since."

"The frustration is not, 'Look how difficult this is.' The frustration is 'Look how difficult this is and what exactly for?'" Smith said.
