Tommy Conlon played by Tom Hardy was placed under arrest at the end of the 4th and final fight in Warrior (2011) because he deserted the Marine Corps after his entire platoon was killed by friendly forces in Iraq.
The story of his desertion was made public when a helmet-cam video showing him heroically rescuing the occupants of a sinking tank was shown on the news.
The scenes in Iraq were actually filmed in an abandoned parking lot outside of Pittsburgh, Pennsylvania. The set was designed by Dan Leigh.
