Training, Korea, and the Start of Vietnam: 1946-1966

After World War II, the 327th Infantry Regiment, including the 1st Battalion (1-327), was inactivated on November 30, 1945. The regiment underwent various redesignations and reactivations between June 1948 and July 1965. During this period, the 1-327 was part of the 1st Brigade, 101st Airborne Division, which became a training center at Camp Breckenridge, Kentucky, following the outbreak of the Korean War in 1950.

The 101st Airborne Division, including the 1-327, was reactivated in 1950 to serve as a training center at Camp Breckenridge until it was inactivated again in December 1953. The division did not see combat during the Korean War, focusing instead on training and preparing for future airborne operations.

Despite not participating in combat during the Korean War, the 1-327 continued to undergo reorganizations and redesignations. In 1954, the regiment was reactivated at Fort Jackson, South Carolina, and later reorganized and redesignated as the 327th Airborne Infantry in 1956.

The 1-327's role during this period was primarily focused on training and preparing for future airborne operations. The battalion did not see significant action until the Vietnam War, when it was deployed as part of the 1st Brigade, 101st Airborne Division, in 1965. The 1-327 would go on to play a crucial role in various combat operations during the Vietnam War, including Operation Austin VI and the Battle of Dak Tan Kan Valley.
