3rd US Infantry Division

3rd US Infantry Division is a division of the United States Army with a continuous lineage dating from World War I through contemporary deployments. Renowned for its disciplines and decisive actions in major 20th- and 21st-century campaigns, the division has served in theaters including Western Front (World War I), Italian Campaign (World War II), European Theater of Operations (World War II), Korean War, Vietnam War, Gulf War, War in Afghanistan (2001–2021), and the Iraq War. The division's soldiers have earned widespread recognition across allied, coalition, and multinational operations.

History

The division was organized during World War I and served on the Western Front (World War I), joining the American Expeditionary Forces under General John J. Pershing and participating in offensives against the German Empire alongside formations from the British Expeditionary Force, French Army (Fourth Republic), and Italian Army sectors. In World War II, the division landed in North Africa as part of Operation Torch and fought through the Tunisia Campaign, the Sicily Campaign, the Salerno landings, and the Anzio landings, later joining the drive across the Italian Campaign (World War II). Redeployed to the European Theater of Operations (World War II), the division earned fame at the Second Battle of the Marne legacy battles and was instrumental in the liberation of towns contested by the Wehrmacht and Waffen-SS. During the Cold War, the division alternated garrison and training roles at Fort Benning, Fort Stewart, and within NATO rotations, preparing for potential conflicts with the Soviet Union. In the late 20th and early 21st centuries, the division deployed brigades to the Persian Gulf War, the Somalia intervention, the Bosnian War, and extensive operations during the Iraq War and War in Afghanistan (2001–2021) as part of multinational coalitions with partners like United Kingdom, France, Germany, and NATO.

Organization and Structure

The division is a modular formation organized around combined arms maneuver brigades, including armored, infantry, artillery, aviation, sustainment, and brigade support elements; its core units have included numbered infantry regiments, armored regiments, and brigade combat teams drawn from the 1st Armored Division doctrinal reforms and U.S. Army Transformation initiatives. Key subordinate formations historically and presently associated with the division include brigades and battalions that trace lineage to the 7th Infantry Regiment, 15th Infantry Regiment, 30th Armor Regiment, and divisional artillery elements such as the 3rd Field Artillery Regiment. The division's aviation assets have supported maneuver operations with units comparable to those in the 101st Airborne Division and 1st Cavalry Division aviation brigades, while logistics and sustainment mirror structures developed at United States Army Training and Doctrine Command facilities. Headquarters elements have operated from installations such as Fort Stewart and coordinated with joint commands including United States Central Command and United States European Command during overseas deployments.

Combat Operations and Campaigns

Throughout its history the division has fought in major campaigns: in World War I during the Meuse-Argonne Offensive and the Second Battle of the Marne sectors; in World War II through Operation Torch, the Tunisia Campaign, the Sicily Campaign, the Salerno landings, the Anzio landings, the drive through the Italian Campaign (World War II), and later in the campaigns that liberated western Europe from the Wehrmacht. During the Korean War era readiness posture and deployments prepared forces against the Korean People's Army threat, while Cold War exercises trained to counter Warsaw Pact contingencies. In the Persian Gulf War the division provided combat power alongside units from the XVIII Airborne Corps and coalition partners in Operation Desert Storm. In the Iraq War the division's brigades participated in initial combat and subsequent stability operations, including major actions against Iraqi Armed Forces and insurgent formations, coordinating with multinational forces from United Kingdom, Australia, and Poland. In Operation Enduring Freedom the division supported counterinsurgency and partnership missions alongside Afghan National Army elements and NATO-led contingents. The division's tactical evolution reflects lessons from combined arms fights against mechanized formations like those fielded by the Wehrmacht and against irregular forces in counterinsurgency campaigns.

Honors and Decorations

The division and its subordinate units have received numerous unit citations and campaign streamers for actions in World War I, World War II, the Persian Gulf War, the Iraq War, and Operation Enduring Freedom. Honors include Presidential Unit Citations and foreign awards granted by allied nations such as decorations from France, Italy, and United Kingdom authorities for battlefield performance during multinational operations like Operation Torch and the liberation campaigns in Europe. Individual soldiers from the division have been awarded the Medal of Honor, Distinguished Service Cross, Silver Star, and campaign-specific medals administered by the Department of Defense, recognizing valor and meritorious service in engagements with adversaries including the German Army (1935–1945), Iraqi Armed Forces, and transnational insurgent groups.

Notable Commanders and Personnel

Notable leaders who commanded or served with the division include generals and officers whose careers intersected with major 20th-century campaigns; among them are figures like John J. Pershing in associated expeditionary command contexts, George S. Patton in theaters where armored doctrine influenced divisional operations, and Lucian Truscott who led corps and army-level formations after divisional assignments. Other prominent personnel who served in or alongside the division advanced to senior roles within the United States Army and multinational commands, participating in events such as the Yalta Conference aftermath planning and NATO force posture adjustments. The division's veterans network includes recipients of high-level awards and participants in historical battles recorded in works on the Italian Campaign (World War II), the Meuse-Argonne Offensive, and modern counterinsurgency operations.
