Includes over 9 maps, 23 diagrams and illustrations. On 23 March 2003, 5,800 U.S. Marines and U.S. Navy Corpsmen-the warriors of Task Force Tarawa-began fighting a ferocious battle in the city of an-Nasiriyah, Iraq. As the first large-scale battle fought by U.S. Marines in Operation Iraqi Freedom, Nasiriyah became a test of the Coalition's ability and resolve to defeat a determined, resourceful foe that relied on a combination of conventional units and tactics and irregular forces willing to violate the laws of war. Task Force Tarawa's Marines adapted quickly, and the battle of Nasiriyah, with its asymmetrical warfare, emphasis on combined arms and joint operations, and Coalition forces' ability to react quickly and aggressively again stun expected enemy tactics became emblematic of the 2003 Operation Iraqi Freedom campaign.
