American 1st Division is a United States Army division formed in 1917 that has served in major conflicts from World War I through the Global War on Terror. The division, nicknamed "The Big Red One", has been associated with leaders such as John J. Pershing, George S. Patton, and Omar Bradley and has participated in campaigns including the Battle of Cantigny, the Meuse–Argonne offensive, the Invasion of Normandy, the Operation Overlord, Operation Desert Storm, Operation Iraqi Freedom, and Operation Enduring Freedom. Its history is intertwined with institutional centers such as Fort Riley, Fort Benning, and theaters such as the Western Front (World War I), the European Theatre of World War II, and the Iraq War.

History

The division was constituted in the Regular Army (United States), organized under orders of American Expeditionary Forces leadership in 1917, and rapidly deployed to the Western Front (World War I). During World War I it fought at Cantigny, Soissons, and the Meuse–Argonne offensive under commanders who answered to John J. Pershing and integrated personnel from regiments such as the 16th Infantry Regiment (United States). After demobilization it was reconstituted between the wars, training at posts including Fort Riley and participating in doctrine development alongside figures like Douglas MacArthur. Reactivated and expanded in World War II, the division conducted amphibious operations in the North African campaign planning and later spearheaded the Operation Overlord landings at Omaha Beach under commanders coordinated with Dwight D. Eisenhower's Supreme Headquarters. Cold War service placed elements in NATO assignments and contingency forces during the Berlin Crisis of 1961. Post-Cold War deployments included Operation Desert Shield/Operation Desert Storm in 1990–1991 and sustained rotations for Operation Iraqi Freedom and Operation Enduring Freedom in the 2000s.

Organization and Structure

Traditionally organized as a triangular infantry division, the division's order of battle has included regiments and brigades such as the 16th Infantry Regiment (United States), the 18th Infantry Regiment (United States), and the 26th Infantry Regiment (United States), as well as divisional artillery like the 1st Field Artillery Regiment (United States). During World War II the division comprised infantry regiments, divisional artillery, reconnaissance elements, engineer battalions, medical battalions, and support services modeled on War Department (United States) doctrine. Reorganization under the United States Army Regimental System and later as a modular brigade combat team introduced combined-arms brigades such as armored, cavalry, and sustainment units aligned with FORSCOM and III Corps or V Corps tasking. Headquarters elements have been sited at installations including Fort Riley, with subordinate units attached to commands like 1st Armored Division for joint maneuvers and to joint task forces for expeditionary operations.

Combat Operations and Deployments

The division's combat record encompasses participation in major offensives across multiple theaters. In World War I it was committed to offensive operations on the Western Front (World War I) in coordination with French armies and British Expeditionary Force sectors. In World War II it executed amphibious assaults in the Sicily campaign planning stage before assaulting Omaha Beach as part of Operation Neptune in support of Operation Overlord. Cold War crises and contingency deployments saw elements rotate to Germany and Southwest Asia, including Saudi Arabia and Kuwait during Operation Desert Shield and Operation Desert Storm. In the Global War on Terror the division conducted stability operations and counterinsurgency missions in Iraq and Afghanistan, integrating with coalition partners such as United Kingdom Armed Forces and multinational task forces.

Notable Engagements and Battles

Fighting at Cantigny in 1918 marked the division's first major offensive victory, followed by actions at Soissons and the Meuse–Argonne offensive. In World War II the division is renowned for actions at Omaha Beach, the Saint-Lô campaign, the breakthrough across the Falaise Pocket, and the advance into Germany culminating in linkup with Soviet Union forces in the late-war period. Later notable operations include spearheading movements in Operation Desert Storm and conducting major counterinsurgency operations in Iraq provinces such as Baghdad Governorate during Operation Iraqi Freedom.

Commanders and Leadership

Commanders associated with the division include early leaders like John J. Pershing and interwar and World War II leaders such as George S. Patton and Omar Bradley, each of whom influenced doctrine and maneuver concepts later institutionalized by United States Army. Postwar commanders implemented reforms tied to doctrine promulgated at United States Army Training and Doctrine Command and operational concepts from U.S. Central Command. The division's staff has often included alumni of professional military education institutions such as United States Military Academy at West Point, Command and General Staff College, and Army War College.

Insignia, Symbols, and Traditions

The division's shoulder sleeve insignia, a simple red numeral "1" on an olive drab shield and the nickname "The Big Red One", originated in World War I and has been trademarked as an iconic symbol recognized alongside other unit emblems such as the 101st Airborne Division "Screaming Eagle" and the 82nd Airborne Division "AA". Traditional ceremonies include unit colors unfurlings, battle streamers displaying campaigns like World War I, World War II, and Southwest Asia, and observances at memorials like the National World War I Museum and Memorial and memorial dedications on posts such as Fort Riley.

Honors, Awards, and Unit Distinctions

The division and subordinate units have received campaign streamers for World War I, World War II, Southwest Asia, Iraq War, and Afghanistan. Unit awards include Presidential Unit Citation (United States), Valorous Unit Award, and foreign decorations issued by allied governments for actions during coalition operations. Individual soldiers from divisional units have been recipients of decorations such as the Medal of Honor, the Distinguished Service Cross, and the Silver Star, reflecting the division's long record of combat distinction and institutional legacy.
