11th Infantry Regiment The 11th Infantry Regiment is a historic regiment of the United States Army with service spanning the American Civil War, Indian Wars, Spanish–American War, Philippine–American War, World War I, World War II, the Korean War, the Vietnam War, and post‑Cold War operations. The regiment served under multiple divisional structures including the 2nd Infantry Division, 5th Infantry Division (United States), and 25th Infantry Division, and participated in campaigns from the Mexican–American War aftermath era realignments through operations in Iraq and Afghanistan. Elements of the regiment have been stationed at posts such as Fort Benning, Fort Carson, Fort Riley, and Camp Casey.

History

Constituted in 1861 amid the American Civil War, the regiment saw early service in theaters where units affiliated with the Army of the Potomac, Army of the Tennessee, and Army of the Cumberland operated. Post‑Civil War reorganizations placed the regiment into frontier service during the Indian Wars and campaigns against the Comanche, Sioux, and Apache; detachments conducted operations coordinated with units from the 7th Cavalry Regiment and the 1st Cavalry Division (United States). During the Spanish–American War, companies deployed to the Cuban Campaign and later to the Philippine–American War where they engaged insurgent forces that had fought in the Battle of Manila (1899). In the interwar years, the regiment was reorganized under reforms influenced by the National Defense Act of 1920 and participated in maneuvers alongside the Infantry School (United States) at Fort Benning.

In World War I and World War II the regiment was integrated into larger formations such as the 2nd Infantry Division and fought in campaigns in France, Belgium, Germany, and the Philippines (1944–45). During the Korean War the regiment participated in major actions on the Pusan Perimeter, the Inchon landing, and advances to the Yalu River before withdrawal operations. In Vietnam the regiment conducted long‑range patrols and counterinsurgency operations in provinces that included Binh Dinh and Quang Nam, often coordinating with units like the 101st Airborne Division and 1st Cavalry Division (Airmobile). Post‑Cold War deployments placed elements into Operation Desert Storm, Operation Iraqi Freedom, and Operation Enduring Freedom.

Organization and Structure

The regiment historically followed U.S. Army infantry tables of organization with battalions, companies, and platoons aligned under regimental headquarters and later under brigade combat teams such as the 1st Brigade Combat Team, 2nd Infantry Division and 3rd Brigade Combat Team, 25th Infantry Division. Typical battalion composition included headquarters and headquarters company, three rifle companies, a weapons company, and a support company, coordinating assets from the Army National Guard and United States Army Reserve during mobilizations. Organizational changes reflected doctrines from the Pentomic reorganization, the ROAD (Reorganization Objective Army Division), and the advent of Stryker Brigade Combat Team concepts, with attachments from the Field Artillery Branch, Combat Engineer Battalion, and Signal Corps elements when deployed.

Combat Deployments and Campaigns

The regiment’s operational history includes participation in the Seven Days Battles, actions in the Western Theater (American Civil War), engagements against Geronimo, amphibious operations in the Cuban Campaign, counterinsurgency in the Philippine Insurrection, offensive and defensive operations in both World Wars including the Meuse-Argonne Offensive and the Battle of the Bulge, and extensive combat in the Korean War and Vietnam War. In modern conflicts, battalions took part in Operation Iraqi Freedom campaigns such as the Battle of Fallujah and stability operations during Operation Enduring Freedom in Helmand Province. The regiment frequently coordinated combined arms operations with the United States Marine Corps, United States Air Force, and Navy SEALs for air-ground integration and special operations support.

Honors and Decorations

Units and individuals of the regiment have received campaign streamers and unit awards tied to major operations including Army Presidential Unit Citation (United States), Valorous Unit Award, Meritorious Unit Commendation (United States), and foreign decorations from allied governments such as the Republic of Korea Presidential Unit Citation and awards associated with the Philippine Republic Presidential Unit Citation. Campaign credits encompass honors for the Civil War, Indian Wars, Spanish–American War, World War I, World War II, Korean War, Vietnam War, and Global War on Terrorism campaigns.

Notable Personnel

Noteworthy figures who served in elements aligned with the regiment include officers and enlisted personnel later associated with the Medal of Honor laureates, senior commanders promoted to ranks such as General (United States), and leaders who later held positions at the Department of the Army and the Pentagon. Members subsequently linked to major historical personalities and units include those who served with the Eighth Army (United States), assigned to commands that intersected with leaders from the Allied forces in World War II, and advisors who later worked with the United Nations Command during the Korean Armistice Agreement period.

Traditions and Insignia

Regimental traditions reflect infantry customs fostered at institutions like the United States Military Academy and the Infantry School (United States), with unit colors, mottos, and marches that evolved alongside changes in doctrine from the Hohenlohe Regiment era influences to modern ceremonial practice at Arlington National Cemetery memorials. Insignia associated with the regiment include distinctive unit insignia approved by the Institute of Heraldry (United States), shoulder sleeve patches when assigned to formations such as the 2nd Infantry Division or 25th Infantry Division, and regimental colors displayed during ceremonies at garrisons including Fort Benning and Fort Carson.
