History

The regiment's history encompasses service in the United States Civil War, participation in Indian Wars actions on the Great Plains, engagements during the Philippine–American War, and expeditionary deployments to Puerto Rico and the Cuban Occupation. During the early 20th century the regiment served on the Mexican Border during the Pancho Villa Expedition and later deployed to the Western Front (World War I). In the interwar years it served in garrison and training roles, before fighting in campaigns of World War II including North African Campaign, Sicily Campaign, and the Italian Campaign. During the Cold War the regiment rotated through postings in Germany, South Korea, and Thailand, and in the late 20th and early 21st centuries elements supported Operations Desert Shield and Desert Storm, Operation Iraqi Freedom, and Operation Enduring Freedom.

Constituted in 1861 amid the American Civil War, the regiment was organized with volunteer and Regular Army components serving in theaters including the Eastern Theater of the American Civil War and the Trans-Mississippi Theater. Officers and enlisted leaders hailed from communities across the United States and fought in battles linked to commanders such as Ulysses S. Grant, William Tecumseh Sherman, and George B. McClellan. Postwar duty involved assignments on the frontier during campaigns involving leaders like George Crook and actions against tribes associated with the Sioux Wars and Nez Perce War. During the Spanish–American War the regiment deployed in expeditionary operations alongside units of the United States Volunteer Infantry and participated in operations that followed the Treaty of Paris (1898).

In World War I the regiment arrived on the Western Front (World War I) and was brigaded with formations from the American Expeditionary Forces under commanders such as John J. Pershing. It participated in operations tied to the Meuse-Argonne Offensive, fighting in sectors that connected with French armies led by figures like Ferdinand Foch and Robert Nivelle. Between the wars the regiment performed peacetime duties including postings at Fort Benning, Fort Leavenworth, and training rotations with the National Guard (United States). Interwar doctrinal developments influenced the regiment via schools such as the United States Army Infantry School and contacts with armor and aviation units like the United States Army Air Corps.

During World War II elements of the regiment took part in amphibious operations in the Mediterranean Theater and fought in campaigns that included Operation Torch, Operation Husky, and the push through the Italian Campaign against forces of the German Wehrmacht and the Italian Social Republic. Postwar occupation duty connected the regiment with governance efforts alongside the United Nations Relief and Rehabilitation Administration and allied commands. Throughout the Cold War the regiment rotated among forward bases in West Germany as part of NATO deterrence, undertook security and contingency missions on the Korean Peninsula alongside United Nations Command (Korea), and trained with partners during exercises such as Operation Reforger and Team Spirit. Assignments included attachment to mechanized and airborne formations, cooperating with units like the 101st Airborne Division, 7th Infantry Division, and 24th Infantry Division.

After the Cold War the regiment deployed to the Persian Gulf during Operation Desert Storm and contributed to stabilization and peace enforcement missions in the Balkans during operations tied to the North Atlantic Treaty Organization. In the 21st century units served in Iraq War campaigns during Operation Iraqi Freedom and in the War in Afghanistan (2001–2021) under United States Central Command and International Security Assistance Force authorities. The regiment has taken part in counterinsurgency operations, partnered training with host-nation forces such as the Iraqi Army and the Afghan National Army, and participated in multinational exercises including Operation Atlantic Resolve and Talisman Sabre. Recent force structure changes reflect integration with brigades of the U.S. Army Forces Command and alignment to modern doctrines promulgated by United States Army Training and Doctrine Command.

The regiment's lineage includes reorganizations, consolidations, and redesignations overseen by the United States Army Center of Military History, resulting in battalion-level elements assigned to different brigades and divisions. Campaign participation credits span the Peninsula Campaign (American Civil War), Sicily Campaign, Anzio, Central Europe (World War II), Korea, Vietnam War, and Iraq War. Decorations awarded to units and individuals include the Presidential Unit Citation (United States), Valorous Unit Award, and multiple foreign honors from allied governments such as France and South Korea. Notable alumni and commanders associated with the regiment have included officers who later served in positions within the Department of Defense, the Joint Chiefs of Staff, and as leaders in peacetime institutions like the United States Military Academy and the Army War College.
