The 157th Infantry/Field Artillery Regiment has been both an infantry and field artillery regiment of the Army National Guard, part of the United States Army. The regiment was first constituted in 1917 during World War I from the 1st Colorado Infantry Regiment. The regiment was an infantry regiment as part of the 40th Infantry Division.
It was again an infantry regiment of the 45th Infantry Division during and after World War II. In 1950 it was removed from the 45th and after the Korean War assigned to the artillery. During the Cold War of the 1960s, 1970s and 1980s, the 1st and 2nd Battalions of the regiment operated the M110 howitzer. The retirement of the M110 system left many National Guard units without a mission. In 2002, the battalions transitioned to the M270 Multiple Launch Rocket System (MLRS) system, and later in 2009 to the M142 High Mobility Artillery Rocket System (HIMARS) system.
Under the current U.S. Army structure, the name "157th Field Artillery Regiment" is used to maintain Regimental Affiliations and has no regimental headquarters or Regimental Commander. 1st and 2nd Battalions (MLRS), 157th Field Artillery Regiment were disbanded in 2006 during the U.S. Army's restructuring from the traditional divisional organizational structure to the modular Brigade Combat Team model. Members from the two battalions were reorganized to form the 3rd Battalion (HIMARS), 157th Field Artillery (designated as 3-157th), part of the 169th Fires Brigade of the Colorado Army National Guard.
