Alerted on 19 January 2003, the 4th Infantry Division was scheduled to take part in the Iraq War in the spring of 2003 by spearheading an advance from Turkey into northern Iraq. The Turkish Parliament refused to grant permission for the operation and the division's equipment remained offshore on ships during the buildup for the war (see below). Its original mission, holding 13 Iraqi divisions along the " Green Line" in northern Iraq, was executed by joint Task Force Viking. The division went north to Ahrweiler, Germany, in the Rheinland-Pfalz area. In July the division returned to France and the last detachment sailed for the United States on 31 July 1919.

The 4th Infantry Division is a division of the United States Army based at Fort Carson, Colorado. It is composed of a division headquarters battalion, three brigade combat teams (two Stryker and one armor), a combat aviation brigade, a division sustainment brigade, and a division artillery. For the Battle of Saint-Mihiel, the division moved into an area south of Verdun as part of the First United States Army. General John Pershing, commander of the American Expeditionary Force (AEF) on the Western Front, had gotten the French and British to agree that the AEF would fight under its own organizational elements. One of the first missions assigned to the AEF was the reduction of the Saint-Mihiel salient. The 4th Division, assigned to V Corps, was on the western face of the salient. The plan was for V Corps to push generally southeast and to meet IV Corps who was pushing northwest, thereby trapping the Germans in the St. Mihiel area. United States.

The 4th Infantry Division consists of a division headquarters battalion, three brigade combat teams (two Stryker and one armored), a division artillery, a combat aviation brigade, and a division sustainment brigade: Under the terms of the Armistice, Germany was to evacuate all territory west of the Rhine. American troops were to relocate to the center section of this previously German-occupied area all the way to the Koblenz bridgehead on the Rhine. The 4th marched into Germany, covering 330 miles in 15 days where it was widely dispersed over an area with Bad Bertrich as division headquarters. The division established training for the men as well as sports and educational activities. In April 1919 the division moved to a new occupation area further north on the Rhine. On 1 April 1957, the division was reorganized as a Pentomic Division. The division's three infantry regiments (the 8th, 12th and 22nd) were inactivated, with their elements reorganized into five infantry battle groups (the 1-8 IN, 1-12 IN, 1-22 IN, 2-39 IN and the 2-47 IN).
