The 3rd Field Artillery Regiment is a field artillery regiment of the United States Army, first formed in 1812, although regimental units trace their lineages as far back as 1794. Based on the service of these antecedents, the regiment claims battle honors for the War of 1812, the Seminole campaign, the Mexican War, the Civil War, the Spanish–American War, and the Philippine Insurrection. The regiment served with the 6th Division during World War I, with the 5th Division, 6th Division and 2d Cavalry Division between the world wars, and with the 9th Armored Division during and after World War II. Since 1961, the regiment has been a parent regiment under the Combat Arms Regimental System and the U.S. Army Regimental System, with regimental elements serving with the 1st, 6th, and 8th Infantry Divisions; 2nd and 3rd Armored Divisions; 1st Cavalry Division; 194th Armored Brigade; and various field artillery brigades and groups. Three regimental battalions are currently active: the 2nd Battalion in the 1st Armored Division and the 1st Battalion and 5th Battalion, both a part of the 17th Field Artillery Brigade.
