Its lineage connects to historic posts, campaigns, and senior infantry traditions within the United States Army and the United States Army Center of Military History.

History

The regiment traces origins to 1812 during the War of 1812 and later served in the Mexican–American War under commanders who operated during campaigns such as the Battle of Chapultepec and the Siege of Veracruz. During the American Civil War the regiment fought in Eastern Theater actions including the Peninsula Campaign, the Battle of Antietam, and the Battle of Gettysburg. In the late 19th century elements deployed for the Spanish–American War and occupation duties in the Philippine–American War. During the 20th century the regiment was engaged in World War I operations in the Meuse-Argonne Offensive and in World War II fought in campaigns such as the North African Campaign and the Italian Campaign. Cold War service included participation in the Korean War and extensive deployments in the Vietnam War with attachments to divisions and corps operating in the I Corps (South Vietnam). In the 21st century, battalions of the regiment took part in Operation Iraqi Freedom and Operation Enduring Freedom.

Organization and Structure

Historically organized as a regimental system under the Regimental combat team concept, the regiment has contained multiple battalions and companies assigned to higher headquarters including numbered divisions such as the 1st Infantry Division, the 2nd Infantry Division, and the 3rd Infantry Division. During reorganizations under the Pentomic and later Reorganization Objective Army Divisions frameworks, units were reflagged, inactivated, or reassigned to brigade combat teams including Stryker Brigade Combat Team and Infantry Brigade Combat Team structures. Elements have served as light infantry, mechanized infantry, and airborne-capable units attached to commands including XV Corps, I Corps (United States), and theater commands during expeditionary deployments.

Campaigns and Operations

The regiment’s campaign credits encompass early 19th-century actions in the War of 1812 and post-war frontier duties on the American frontier. In the 1840s and 1850s it fought in major operations of the Mexican–American War and later in insurrection operations in the Philippine–American War. Civil War engagements list numerous battles across the Eastern Theater. In World War I the regiment participated in operations alongside Allied formations such as the American Expeditionary Forces (AEF), and in World War II fought in operations across the European Theater of Operations and the Mediterranean Theater of Operations, including amphibious and mountain warfare phases. Korea and Vietnam operations saw involvement in defensive and offensive campaigns including the Pusan Perimeter and operations in the Ia Drang Valley. Modern campaigns include stability, counterinsurgency, and partnered operations throughout Iraq and Afghanistan.

Honors and Decorations

The regiment and its battalions have received multiple unit decorations and campaign streamers awarded by authorities such as the Department of the Army and the United States Congress. Honors include campaign streamers for major conflicts including the War of 1812 streamer, Mexican War streamer, Civil War streamers, World War I and World War II campaign streamers, as well as Korean War and Vietnam War streamers. Individual battalions have earned Valorous Unit Awards, Presidential Unit Citations, and foreign decorations from allied governments for distinguished service during campaigns such as the Meuse-Argonne Offensive and the Italian Campaign.

Notable Commanders and Personnel

Notable leaders associated with the regiment include officers who later served in high command and political roles, with links to institutions and events such as the United States Military Academy, the Army War College, and national leadership during times of conflict. Officers and enlisted personnel received recognition including the Medal of Honor for valor in actions spanning the Civil War through 20th-century conflicts. The regiment’s alumni intersect with figures involved in major events such as the Battle of Gettysburg, the Battle of the Bulge, and postwar reconstruction efforts in occupied territories.

Traditions and Insignia
