The Lucky Ones (2007)

The story revolves around three soldiers - Colee, TK and Cheever - who return from the war after suffering injuries and learn that life has moved on without them. They end up on an unexpected road trip across the U.S., with Colee on a mission to bring her boyfriend's guitar back to his family because he saved her life, TK seeking the confidence to face his wife after a shrapnel injury threatens his sexual function, and middle-aged Cheever planning to hit the casinos in a desperate effort to pay for his son's college tuition.
