In March of 2003, the Marine Corps sent two columns north across the Iraqi desert to help the Army seize Baghdad. Planners knew that if there was going to be trouble, it would happen on a stretch of road between two bridges in Nasiriyah. They were right. SHOOTOUT details what happened when a convoy of Army supply trucks (the 507th Maintenance Company) took a wrong turn onto "Ambush Alley." With escape in sight, the Marines found themselves in a heated firefight with black-robed Fedayeen fighters. Over the next several hours, they tried to fight their way out, save their wounded comrades and complete their mission.
