The primary focus of the book is I Marine Expeditionary Force (I MEF)-the runup to the war in 2002 and early 2003, especially the development of "the plan," with its many changes, the exhaustive rehearsals, and other preparations, and then the conduct of decisive combat operations and the immediate postwar period, mostly under the control of the U.S. Central Command's Coalition Forces Land Component Command. The book also touches upon other Marine activities in the Military Coordination and Liaison Command in northern Iraq and with the British in the south. Nonetheless, the primary focus remains on I Marine Expeditionary Force and the interactions of its constituent elements.
