The 4th Infantry Division is a division of the United States Army based at Fort Carson, Colorado. It is composed of a Headquarters and Headquarters Battalion, three brigade combat teams (1st Stryker BCT, 2nd Infantry BCT, and 3rd Armored BCT), a Combat Aviation Brigade, the 4th Infantry Division Sustainment Brigade, and a Division Artillery.

The 4th Infantry Division's official nickname, "Ivy", is a play on words of the Roman numeral IV or 4. Ivy leaves symbolize tenacity and fidelity which is the basis of the division's motto: "Steadfast and Loyal." The second nickname, "Iron Horse," has been adopted to underscore the speed and power of the division and its soldiers.

The 4th Division was organized at Camp Greene, North Carolina on 10 December 1917 under the command of Maj. Gen. George H. Cameron. It was here they adopted their distinctive insignia, the four ivy leaves. The ivy leaf came from the Roman numerals for four (IV) and signified their motto "Steadfast and Loyal". The division was organized as part of the United States buildup following the Declaration of War on 6 April 1917 and the entry of the United States into the war on the side of the British and French.

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 St. 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.
