After returning to the United States in September 2003, the battalion re-deployed in February 2004 to Al Qaim—in western Al Anbar Province, abutting the Syrian border. Their area of responsibility included Husaybah, the primary border-crossing point between Syria and Iraq. Increased military presence resulted in continuous fighting, including large-scale operations to retake the city of Husaybah from insurgents and local fighters in April. The Medal of Honor was posthumously awarded to Kilo Company squad leader Jason Dunham for actions in the city of Karabilah. They returned from that deployment in September 2004.
