4th Battalion, 320th Field Artillery Regiment

The 4-320th FAR's beginnings can be traced back to America's entry into the World War I. As part of the nation's mobilization, 4-320th was constituted, organized and activated in August 1917 as Battery D, 320th Field Artillery (D/320th FA). As part of the original 82nd Division, D/320th FA played a key role at Lorraine, St. Mihiel, and the Meuse Argonne region in France. Following the Armistice, the 320th FA demobilized, only to be reconstituted in June 1921 as part of the United States Organized Reserves.

In August 1942, when the 82nd Infantry Division was converted to an airborne division, the 320th FA was reorganized and redesignated as the 320th Glider Field Artillery Battalion (GFAB). Because the GFAB had only three firing batteries, the lineage of D/320th was consolidated with A/320th. As part of the 82nd Airborne Division, the 320th GFAB fought in a number of hot spots. First, the 320th GFAB was part of the campaign in Sicily, acting in reserve. The unit first saw action at the Volturno River on the Italian mainland. The crucial Normandy invasion was the next stop for the 320th GFAB. Under difficult conditions, the unit helped make the invasion a success. As a result of the 320th's actions during Operation Overlord, the unit was awarded the Presidential Unit Citation. The 320th GFAB next fought in Operation Market Garden and then the Battle of the Bulge when the Germans attempted their last-ditch offensive. The 320th GFAB then fought and played a role in the final push through the Rhineland to defeat Germany. Upon the war's end the unit completed its duties in Europe as part of the post-war occupation in Berlin.

After the war, the 320th GFAB went through a number of transitions. It was inactivated on 15 December 1948 and relieved from assignment to the 82nd Airborne Division on 14 December 1950. On 1 August 1951 it was reorganized and redesignated as the 320th Airborne Field Artillery Battalion (AFAB), and activated at Fort Benning, Georgia.
During the 1950s, the 320th FA served as the field artillery battalion of the separate 508th Airborne Regimental Combat Team. When the Army eliminated infantry regiments and battalions from division and organized under the Pentomic structure, the 320th Field Artillery was reorganized as a parent regiment under the Combat Arms Regimental System. D/320th was assigned to the 82nd Airborne Division until 1964, but inactivated when the Army restructured to the Reorganization Objective Army Division in 1964.

As part of the transition to the U.S. Army Regimental System in 1986, D/320th was activated in the 193rd Infantry Brigade in the Panama Canal Zone. The battery participated in Operation Just Cause before being inactivated again in 1994.

As part the Army's reorganization to modular brigade combat teams, D/320th was redesignated as Headquarters and Headquarters Battery, 4th Battalion, 320th Field Artillery. The battalion activated on 16 September 2004 at Fort Campbell, Kentucky and assigned to the 4th Brigade Combat Team, 101st Airborne Division.

With the 4th BCT, 4-320th FAR deployed to Iraq in support of Operation Iraqi Freedom from 2005–2006, and to Afghanistan in support of Operation Enduring Freedom from 2008–2009, 2010–2011, and in 2013.
