24th Infantry Division

24th Infantry Division The 24th Infantry Division was a major formation of the United States Army activated in 1921 that served in World War II, the Korean War, the Cold War, and the Gulf War. The division’s lineage connects to interwar reorganizations, Pacific campaigns, defensive operations on the Pusan Perimeter, large-scale offensives on the Pusan Perimeter line, Cold War stationing in Japan and the continental United States, and rapid deployment for Operation Desert Shield and Operation Desert Storm. Its legacy involves multiple deactivations and reflagging actions tied to force restructuring under the Unified Command Plan and the Base Realignment and Closure Commission.

History

The division was constituted in the aftermath of the National Defense Act of 1920 and organized during the post‑World War I Army drawdown at Fort Sam Houston, with early peacetime assignments shaped by the Interwar period (1920–1939). During World War II, the division trained for amphibious operations across the Pacific War theater, participating in campaigns that intersected with the Guadalcanal Campaign, Leyte campaign, and operations associated with General Douglas MacArthur’s island‑hopping strategy. Entering the Korean War as part of the United Nations Command, the division engaged in defensive and counteroffensive operations following the Inchon Landing and during the fighting around the Naktong River and the Pusan Perimeter. During the Cold War the division rotated between forward deployment in Japan and readiness postures in the continental United States, influenced by strategic policies from the Department of Defense and declarations from successive Presidents of the United States. In 1990–1991 the division deployed brigades to Saudi Arabia and participated in Operation Desert Storm under U.S. Central Command, contributing to the liberation of Kuwait and the defeat of Iraq’s invading forces.

Organization and Structure

The division’s Table of Organization and Equipment evolved from a triangular infantry division model to an armored and mechanized configuration influenced by lessons from World War II and doctrinal shifts during the Cold War. At various times its core maneuver elements included three infantry brigades or regiments such as the 19th Infantry Regiment, 21st Infantry Regiment, and 34th Infantry Regiment, supported by division artillery like the 41st Field Artillery Regiment, armor units including elements of the 64th Armor Regiment, and combat support from the Special Troops Battalion. Aviation elements interacted with units of the 101st Aviation Regiment and Army Aviation Branch concepts, while sustainment was provided by units analogous to a Division Support Command and the Medical Corps. Command and control structures interfaced with higher headquarters such as Eighth United States Army in East Asia and III Corps and XVIII Airborne Corps during stateside alignments. Equipment modernization saw integration of platforms like the M1 Abrams, M2 Bradley Infantry Fighting Vehicle, and field artillery systems including the M198 howitzer.

Combat Operations and Deployments

In World War II the division conducted amphibious assaults and island operations that aligned with campaigns directed by Admiral Chester Nimitz and General Douglas MacArthur, coordinating with United States Navy and United States Marine Corps forces. During the Korean War the division fought in major actions linked to the strategic crisis after the North Korean invasion of South Korea, operating alongside units from the Republic of Korea Army, elements of the British Commonwealth Forces Korea, and under the multinational United Nations Command. The division’s actions at defensive lines such as the Pusan Perimeter and offensive drives toward the Yalu River involved engagements with the Korean People’s Army and later confrontations with the Chinese People’s Volunteer Army. In the late 20th century the division’s brigades deployed for Operation Desert Shield and conducted combat operations in Operation Desert Storm, coordinating with coalition partners including forces from the United Kingdom, France, Saudi Arabia, Egypt, and Syria insofar as coalition logistics and command arrangements permitted. The division’s maneuver, fires, intelligence, and sustainment tasks interacted with joint components like U.S. Air Force close air support, Naval logistics, and multinational liaison elements.

Postwar Reorganizations and Inactivations

Following major conflicts the division underwent multiple reorganizations driven by directives from the Department of the Army and force reductions under defense secretaries and presidential administrations. Cold War era transformations converted the division between light, mechanized, and armored configurations, with stationing changes from Fort Riley to Fort Stewart and forward deployments in Japan’s Kanto Plain and Okinawa policy frameworks. Post‑Cold War force drawdowns after the Gulf War and the 1991 Base Realignment led to reflagging actions tied to United States Army Forces Command restructuring; the division was inactivated and its lineage consolidated into other units during the 1990s as part of the Army’s transition to modular brigade combat teams under initiatives influenced by the Chief of Staff of the Army and the Congressional defense appropriations process.

Honors and Notable Commanders

The division earned campaign streamers for World War II Pacific Theater operations, multiple Korean War campaign credits including UN Offensive and Chinese Intervention phases, and decorations reflecting brigade and regimental citations from the Department of the Army. Notable commanders who led the division or its major subordinate commands include generals who also served in theaters such as General Matthew Ridgway, General Walton Walker, and senior leaders who later held posts in Eighth United States Army and United States Army Pacific. The division’s heraldry and unit awards reflect associations with corps and army level campaigns, and its veterans have been recognized by organizations such as the Veterans of Foreign Wars and the American Legion.
