45th Field Artillery Group was a United States Army artillery formation that served in multiple mid-20th century campaigns, providing indirect fire support, coordination, and logistics for maneuver formations. The unit operated alongside corps and division elements during World War II, the Korean War, and the Cold War, integrating systems and doctrine from institutions such as the United States Army Field Artillery Branch, United States Army Center of Military History, and United States Army Training and Doctrine Command. It interacted with allied formations including the British Army, French Army, South Korean Army, and NATO commands such as United States European Command.
The group's lineage traces through Continental mobilization in World War II, with roots in continental campaigns like the Normandy landings and the Allied invasion of Sicily while supporting corps-level operations across the Western Front (World War II), Battle of the Bulge, and subsequent advances into Germany. Postwar reorganization tied the group to occupation duties associated with the United States Army Europe and later Cold War readiness amid crises such as the Berlin Blockade and NATO exercises like Operation Reforger. During the Korean War era, elements were reflagged and reassigned to support combat in the Korean War theater, coordinating with units engaged in battles such as the Battle of Pusan Perimeter and Battle of the Imjin River. In the Vietnam War period and later Cold War decades, the group adapted to doctrinal shifts from the Pentomic reorganization to the AirLand Battle concept promulgated by United States Army Training and Doctrine Command and thinkers at the United States Military Academy and Naval War College. Deactivations and reactivations were influenced by force structure changes from the Goldwater–Nichols Act era and post–Cold War reductions following the Dissolution of the Soviet Union.
At various times the group comprised several battalions, batteries, and fire direction centers drawn from regiments such as the 1st Field Artillery Regiment, 5th Field Artillery Regiment, 7th Field Artillery Regiment, 8th Field Artillery Regiment, and 27th Field Artillery Regiment. Command relationships placed the group under corps headquarters including the I Corps (United States), V Corps (United States), VII Corps (United States), and combined commands like Combined Joint Task Force. Staff functions reflected doctrine from the Field Artillery School (United States), incorporating fire support coordination elements used by Division Artillery (United States Army) and liaison with aviation units such as the 1st Cavalry Division (United States) and 101st Airborne Division (United States) for aerial observation. The group headquarters typically contained a headquarters battery, intelligence sections that used formats from the Defense Intelligence Agency, logistical support tied to United States Army Materiel Command, and medical support coordinated with United States Army Medical Department elements.
The group's arsenal evolved from towed pieces like the M1 155 mm howitzer and M114 155 mm howitzer to self-propelled systems including the M7 Priest, M109 Paladin, and rocket artillery such as the M270 Multiple Launch Rocket System. For targeting, the unit integrated technologies from the AN/MPQ radar series, the Defense Support Program, and later sensors tied to the Global Positioning System and platforms like the Lockheed C-130 Hercules for aerial delivery. Fire control incorporated systems derived from the Field Artillery Tactical Data System and command nets used by Tactical Air Control Party elements. Ammunition types ranged across munitions standardized by NATO agreements, including high-explosive, illumination, and precision-guided munitions such as variants developed under programs at the U.S. Army Armament Research, Development and Engineering Center.
Operational deployments placed the group in theaters spanning Northwest Europe (WWII), the Korean Peninsula, and forward locations in West Germany during NATO deterrence. It participated in combined operations with allies at exercises like Bright Star, Topolski, and Victory Strike, and in contingency responses such as the 1958 Lebanon crisis and Cold War alert rotations tied to the Strategic Arms Limitation Talks era posture. The group's operational tempo involved fire missions supporting offensive operations during the Hundred Days Offensive equivalents in later conflicts, sustained counter-battery tasks, and support to stabilization operations tied to civil affairs units like the Civil Affairs and Psychological Operations Command. Coordination with air defense units such as the 1st Infantry Division (United States)’s accompanying ADA batteries ensured protection during forward deployments.
Leaders associated with the group's lineage included field-grade and general officers who later served in commands such as United States Army Training and Doctrine Command, United States Army Europe, U.S. Forces Korea, and on the Joint Chiefs of Staff staff. Senior enlisted advisors moved into positions within the Sergeant Major of the Army network and influenced doctrine at the John F. Kennedy Special Warfare Center and School and the United States Army Command and General Staff College. Personnel who served in the group went on to assignments in institutions such as the Pentagon, the National Security Council, and international postings with the North Atlantic Treaty Organization.
Insignia elements reflected heraldry practices codified by the Institute of Heraldry (U.S. Army), with distinctive unit insignia, shoulder sleeve insignia, and guidons following standards used by the United States Army Institute of Heraldry. Ceremonial traditions aligned with those of the Field Artillery School (United States), including the wearing of branch-specific items seen at events at Fort Sill and observances linked to commemorations such as Memorial Day and Veterans Day. Unit customs incorporated honors and streamers authorized by the Department of the Army and were displayed at ceremonies involving allied representatives from commands like United States European Command and national military academies such as the United States Military Academy.
