6th Infantry Regiment (United States) is a historic infantry regiment of the United States Army with origins in the War of 1812. The regiment served in major conflicts including the Mexican–American War, the American Civil War, the Philippine–American War, the World War I, the World War II, the Korean War, the Vietnam War, and operations in Bosnia and Herzegovina, Iraq War, and War in Afghanistan (2001–2021). Elements of the regiment have been assigned to divisions such as the 1st Infantry Division (United States), the 2nd Infantry Division (United States), the 25th Infantry Division (United States), and the 10th Mountain Division (United States), reflecting a long service record across theaters like Europe, the Pacific Ocean, and Asia.

History

The regiment traces its origin to companies raised during the War of 1812 under the auspices of the United States Congress and served in frontier garrisons, the Second Seminole War, and the Black Hawk War. During the Mexican–American War, elements participated in the Siege of Veracruz and campaigns under Winfield Scott and Zachary Taylor. In the American Civil War, the regiment was split between Union assignments and fought in campaigns linked to the Army of the Potomac and operations in the Western Theater, encountering commanders such as Ulysses S. Grant and William Tecumseh Sherman. After Reconstruction, the regiment deployed to the Philippines during the Philippine–American War and served in garrison duty during the Pancho Villa Expedition. In World War I, elements joined the American Expeditionary Forces and participated in operations on the Western Front alongside units from France and the United Kingdom. In World War II, battalions fought in the Aleutian Islands campaign, the Normandy landings for some attached units, and in the Pacific War campaigns. Cold War deployments included service along the Korean Peninsula during the Korean War and counterinsurgency operations in Vietnam War with attachments to the 101st Airborne Division (United States). Post-Cold War, battalions have rotated through peacekeeping in Bosnia and Herzegovina, combat in Iraq War including Operation Iraqi Freedom, and counterinsurgency and stability operations during the War in Afghanistan (2001–2021).

Lineage and Honors

The regiment's lineage encompasses multiple reorganizations under the United States Army Center of Military History and designations under statutes enacted by the United States Congress. Regimental honors include campaign streamers for the New Orleans operations of the War of 1812, Contreras and Churubusco in the Mexican War, Civil War engagements such as Antietam and Gettysburg for certain elements, Philippine campaigns, the Meuse-Argonne Offensive in World War I, and Iwo Jima and Okinawa in World War II where attached companies received credits. Unit decorations include awards from the Department of the Army, foreign honors from France and Republic of Korea, and Presidential Unit Citations for actions linked to commanders and units such as Douglas MacArthur's theater operations and actions during Korean War offensives. Campaign participation credit lists reflect attachments to formations including the 1st Cavalry Division (United States) and theater-level task forces during Operation Enduring Freedom.

Subordinate elements typically comprised rifle companies, weapons companies, and support detachments aligning with brigade combat team organization under the Modular Force transformation. The regiment's battalions have rotated between light infantry, mechanized infantry, and airborne roles with attachments to formations such as the 82nd Airborne Division for specific deployments.
