Home of the Brave (2006)

The day after they get the word they'll go home in two weeks, a group of soldiers from Spokane are ambushed in an Iraqi city. Back stateside we follow four of them - a surgeon who saw too much, a teacher who's a single mom and who lost a hand in the ambush, an infantry man whose best friend died that day, and a soldier who keeps reliving the moment he killed a civilian woman.
