4th Infantry Regiment (United States)

4th Infantry Regiment (United States) is one of the oldest and most decorated units in the United States Army, tracing its origins to 1796. Known as the "Warriors," the regiment has served in nearly every major American conflict from the War of 1812 through the Global War on Terrorism. Its current battalion is stationed at Joint Base Lewis-McChord in Washington.

History

The regiment was constituted in 1796 as the original 4th Infantry in the Regular Army, with its first significant combat occurring during the War of 1812 at the Battle of Lundy's Lane. It fought with distinction in the Mexican–American War, participating in key battles like Monterrey and the Buena Vista. During the American Civil War, the regiment was heavily engaged in the Western Theater, including the pivotal Battle of Shiloh and the Siege of Vicksburg. In the late 19th century, it was deployed across the American frontier, engaging in the Indian Wars against tribes such as the Sioux and the Nez Perce. The 4th Infantry later saw service in the Spanish–American War in Cuba and the subsequent Philippine–American War.

Lineage and honors

The regiment's official lineage is maintained by the United States Army Center of Military History. Its honors include the campaign participation credit for over forty named wars and conflicts. The unit holds a unique place in the United States Army Regimental System, having never been disbanded since its inception. Its battle honors are displayed on its regimental colors, which feature streamers for every campaign from the War of 1812 to Operation Iraqi Freedom. The regiment's coat of arms and distinctive unit insignia incorporate symbols from its storied past, including a Maltese cross from the Civil War Campaign Medal.

Campaign participation credit

The regiment has earned credit for campaigns in the War of 1812, the Mexican–American War, and the American Civil War. In the 20th century, it fought in World War I as part of the 3rd Infantry Division in major offensives like the Meuse-Argonne Offensive. During World War II, it participated in the Allied invasion of Sicily, the Battle of Anzio, and the drive through the Gothic Line. The regiment later served in the Korean War with the 2nd Infantry Division, notably at the Battle of Chipyong-ni. In the Vietnam War, it was awarded a Presidential Unit Citation for actions in the Ia Drang Valley. More recently, elements deployed to Iraq for Operation Iraqi Freedom.

Distinctive unit insignia and coat of arms

The distinctive unit insignia is a gold color metal and enamel device featuring a blue Maltese cross from the Civil War Campaign Medal, charged with a silver rifle from the Great Seal of the United States. The regimental coat of arms displays a shield with a blue chief and a white field, symbolizing service in the War of 1812. The crest is a rattlesnake coiled to strike, embodying the motto "Noli Me Tangere" (Do Not Touch Me), a design approved by the The Institute of Heraldry. These heraldic items are worn on the Army Service Uniform and displayed on unit guidons.

Notable members

Several distinguished soldiers have served in the regiment, including Zachary Taylor, who commanded it before becoming the 12th President. Ulysses S. Grant also served with the 4th Infantry early in his career prior to his command of the Union Army. Renowned explorer John C. Frémont was a lieutenant in the regiment during his early topographic expeditions. In the modern era, General Barry McCaffrey served as a platoon leader and company commander with the unit during the Vietnam War.

Current status and organization

As of the latest reorganization under the United States Army Regimental System, the regiment's only active element is the 1st Battalion, 4th Infantry Regiment. This battalion serves as the opposing force (OPFOR) for the I Corps at the Joint Base Lewis-McChord Yakima Training Center. It falls under the operational control of the 7th Infantry Division and is tasked with providing realistic combat training for Army and allied units. The battalion maintains the regiment's legacy and continues to train for global deployment.
