1st Infantry Regiment (United States) - Korean War and Reactivation

Korean War and Reactivation

On January 10, 1949 1st IR was inactivated in Korea, and then was reactivated on October 4, 1950 at Fort Ord, California as a training regiment for units being sent to the fight in Korea. On April 3, 1956, the regiment was relieved from assignment to the 6th Infantry Division, and then was assigned on May 15, 1956 to the United States Military Academy at West Point, New York. On May 15, 1958 the regiment was reorganized under the Combat Arms Regimental System as HHC, 1st Battle Group, 1st Infantry Regiment.

In 1960, the 1st Battle Group, 1st Infantry was reorganized under a concept that provided sufficient tactics instructors in the permanent party for continuity, but called for outside augmentation for the summer training program. This left the battle group with a Headquarters, Headquarters and Training Company, Service Company, Airborne Detachment, the 2nd Aviation Detachment, the USMA Band, Detachment 1 and 2 United States Army Hospital, and saw the attachment of the 50th Engineer Battalion (Construction) and the 57th Military Police Company. The old Military Police Detachment personnel formed the nucleus of the newly attached 57th Military Police Company.

On May 16. 1961, the mission of providing tactical instruction for the Corps of Cadets along with the personnel involved, was transferred to a newly created Office of Military Instruction in the Department of Tactics. All enlisted personnel remained assigned to the battle group. On February 1, 1962, Service Company was eliminated and its personnel absorbed into Headquarters Company.

On January 1, 1965, the 1st Battle Group, 1st Infantry was redesigned as the 1st Battalion, 1st Infantry. With the exception of transferring tactical instruction to the Office of Military Instruction (now DMI) in 1961, its mission was essentially unchanged. The 2nd Battalion was then assigned to Fort Benning, Georgia.
