3rd Infantry Division (United States) The 3rd Infantry Division is a United States Army division with a long record of service in major 20th and 21st century conflicts, noted for rapid offensive operations and heavy mechanized maneuver. It has fought in the World War I, World War II, Korean War, Gulf War, Iraq War, and War in Afghanistan (2001–2021), and is garrisoned at Fort Stewart, Georgia, as part of United States Army Forces Command.

History

Raised in 1917 for service with the American Expeditionary Forces (AEF), the division participated in the Château-Thierry (1918), Aisne-Marne Offensive, and Meuse-Argonne Offensive campaigns under commanders aligned with John J. Pershing's staff. Between wars the division was reorganized during the Interwar period and reconstituted for World War II where it fought in the North Africa Campaign, Sicily Campaign, Italian Campaign, and the drive up the Italian Peninsula culminating in the crossing of the Gustav Line and operations near the Po River. Reassigned to the European Theater, the division conducted the amphibious Operation Shingle-style landings and advanced through France and into Germany. During the Korean War the division executed the Inchon Landing follow-on operations and held positions along the 38th parallel; it later returned to Europe during the Cold War as part of United States Army Europe (USAREUR). In the post-Cold War era the division deployed elements to the Persian Gulf War (1990–1991), the Iraq War including the 2003 invasion of Iraq, and to operations in Afghanistan (2001–2021), participating in counterinsurgency and stability missions alongside formations from XVIII Airborne Corps, III Corps, and multinational coalitions.

Organization and Structure

The division is a combined arms headquarters subordinate to United States Army Forces Command and typically comprises multiple brigade combat teams, an aviation brigade, a divisional artillery brigade, a sustainment brigade, and specialized battalions. Historically organized under the square division and later the triangular division tables of organization, it transitioned to the Brigade Combat Team concept during the Modularity (United States Army) reforms, fielding Stryker Brigade Combat Team and Armored Brigade Combat Team elements at different times. Units assigned have included storied regiments such as the 7th Infantry Regiment, 15th Infantry Regiment, and 30th Infantry Regiment, plus support from 1st Battalion, 3rd Field Artillery Regiment-type formations and aviation assets like the 101st Combat Aviation Brigade-style organizations when task organized. The division's command relationships have frequently involved III Corps, XVIII Airborne Corps, and joint task force headquarters for expeditionary operations.

Combat Operations

In World War I the division conducted offensive operations during the Second Battle of the Marne and the Meuse-Argonne Offensive, cooperating with French and British armies. During World War II the division executed amphibious assaults in Operation Husky and hard fought advances through the Italian Campaign against Wehrmacht forces, later transferring to operations supporting the Allied invasion of Southern France and drives into Germany. In the Korean War it engaged in mobile warfare and defensive operations against Korean People's Army and People's Volunteer Army forces, participating in counterattacks and static defense along key terrain. In the Gulf War elements participated in the coalition ground offensive that routed Republican Guard and Iraqi Army formations. During the Iraq War the division led the northern flank of the 2003 invasion of Iraq and later conducted counterinsurgency operations in Tikrit and Mosul-area provinces. In Afghanistan the division trained and partnered with Afghan National Army units and undertook security, advisory, and stability tasks during Operation Enduring Freedom.

Training and Doctrine

Training follows doctrine promulgated by United States Army Training and Doctrine Command (TRADOC) and incorporates combined arms maneuver, urban operations, and counterinsurgency methodologies drawn from manuals like Field Manual 3-0 and FM 3-24. The division conducts large-scale exercises at ranges including National Training Center (Fort Irwin) and Joint Readiness Training Center (Fort Polk), participates in multinational exercises with NATO partners and bilateral training with United Kingdom Armed Forces, German Army, and Republic of Korea Army units, and emphasizes interoperability with United States Marine Corps and United States Air Force close air support procedures. Professional military education for officers and noncommissioned officers includes attendance at United States Army War College, Command and General Staff College, and career courses aligned with combined arms doctrine.

Equipment and Insignia

The division fields a mix of armored and mechanized equipment such as the M1 Abrams, M2 Bradley, Stryker family vehicles, M109 Paladin self-propelled artillery, M777 howitzers, and rotary-wing aircraft like the AH-64 Apache and UH-60 Black Hawk. Small arms common to the division include the M4 carbine and M240 machine gun. Its distinctive shoulder sleeve insignia is a blue-and-white striped pattern symbolizing the division's nickname and European service; the division's distinctive unit insignia and motto reflect honors awarded including Distinguished Service Cross and Medal of Honor recipients who served in its ranks. Unit awards include Presidential Unit Citation streamers from major campaigns.

Patton served in divisional command contexts early in his career; General Joseph W. Stilwell influenced divisional operations in multiple theaters; the division's ranks have included Audie Murphy, a Medal of Honor recipient and one of the most decorated American combat soldiers of World War II, and other decorated officers such as Omar N.
