Major General Charles H. Muir assumed command on 11 December 1917.[3] The organization was a "square" division (i.e., there were four infantry regiments) with an authorized strength of 28,105 personnel.

The entire division arrived in France by 1 May 1918 and components of the units were deployed into the front line.

The division then served for the next few months in the Army of Occupation, being based in Belgium and Esch-sur-Alzette, Luxembourg until it departed Europe. The division returned to the United States through the New York Port of Embarkation at Hoboken, New Jersey, on 21 July 1919.
Insignia
The 5th Division adopted a red diamond as its shoulder sleeve insignia.[5] The color red was selected in honor of World War I commander John E. McMahon, who was a member of the Army's Field Artillery branch.[6] The diamond shape was chosen in recognition of the Diamond Dyes company, a maker of fabric coloring products whose ad slogan "It Never Runs" conveyed a martial meaning during war.[6] The shape of the diamond in the 5th Division's insignia represents strength, because in bridge construction the trusses that provide the greatest durability are mutually supporting isosceles triangles.[6]

During the period 1921–39, the active elements of the 5th Division consisted of the 10th Infantry Brigade and other assorted divisional elements which formed the base force from which the remainder of the division would be reactivated in the event of war.The division headquarters was organized on 5 May 1926 as a "Regular Army Inactive" (RAI) unit with

The 5th Infantry Division, now commanded by Major General Stafford LeRoy Irwin, left Iceland in early August 1943 and was sent to England to prepare and train for the eventual invasion of Northwest Europe, then scheduled for the spring of 1944. Upon arrival in England the 5th Division was stationed at Tidworth Barracks in South West England, before moving to Northern Ireland.

In February and March, the division drove across and northeast of the Sauer, where it smashed through the Siegfried Line and later took part in the Allied invasion of Germany.

However, the division was reactivated on 15 July 1947 under Brigadier General John H. Church.[citation needed] From 1951 to 1953, the division was stationed at Fort Indiantown Gap, Pennsylvania, and trained 30,000 replacements for the Korean War. The later part of the 1950s saw the division stationed in West Germany as part of the U.S. contribution to NATO, though the division later returned to the United States.
Vietnam War


When the 1st Infantry Division deployed to South Vietnam in 1965, additional maneuver battalions were required; thus two infantry battalions from the 2nd Brigade, 5th Infantry Division, at Fort Devens in Massachusetts were relieved and assigned to "The Big Red One."[16] In September 1965, the 2nd Brigade, 5th Infantry Division was moved, minus personnel, to Fort Carson in Colorado and refilled there. The remaining personnel at Fort Devens formed the basis of the 196th Infantry Brigade.
By 1968 the division was stationed at Fort Carson, Colorado, as a mechanized formation.

Two Soldiers were killed in action from the 5th Infantry Division during Just Cause: CPL Ivan M. Perez and PVT Kenneth D. Scott.[19]
