2:321st FA

The 2nd Battalion, 321st Field Artillery Regiment (2/321st FA) traces its origins to the 321st Field Artillery, which was constituted in 1917 as part of the 82nd Division during World War I. The unit served with distinction in France, supporting infantry operations in key campaigns such as St. Mihiel and Meuse-Argonne. Reactivated during World War II as part of the 101st Airborne Division, 2/321st FA provided critical airborne artillery support during the Normandy landings, Operation Market Garden, and the Battle of the Bulge. The battalion continued to serve in subsequent conflicts, including the Vietnam War, before its inactivation and eventual reflagging in the post-Cold War era.
