The 75th Infantry Division was a formation of the United States Army first activated during World War II. Raised at Fort Leonard Wood, Missouri in April 1943, it deployed to the European Theater and participated in late-war campaigns. After the war the division was inactivated, later served as a combat formation in the Organized Reserves during the 1950s, and was reestablished in a training-support role in the Army Reserve in 1993. For a concise reference see the division listing at 75th Infantry Division and general Army sources such as U.S. Army.
Characteristics and organization
As an American infantry division of its era, the 75th was organized to conduct ground combat operations with an emphasis on infantry maneuver supported by artillery, engineers, reconnaissance, medical, and logistical elements. Divisional organization in World War II typically included three infantry regiments (or infantry battalions in later tables of organization), an artillery brigade or battalion group, and support units for supply and communications. The division's primary mission was to seize and hold terrain, reduce enemy strongpoints, and exploit breakthroughs in coordination with armored and air forces.
World War II service
Activated on 15 April 1943 at Fort Leonard Wood, the division shipped to the European Theater where it arrived in time to take part in winter 1944–1945 and spring 1945 operations. It saw combat during the Ardennes and Rhineland campaigns and advanced into central Germany during the final Allied offensives. The division earned campaign credits for its role in these operations and contributed to the collapse of German resistance in its area of operations.

Postwar, reserve duty and reactivation
After returning from Europe the 75th was inactivated like many wartime units. It was later reconstituted as a combat division in the Organized Reserves and remained active in that status between 1952 and 1957. In 1993 the Army Reserve reactivated the unit as the 75th Division (Training Support), converting its mission from tactical combat to preparing and training Army Reserve and National Guard units for deployment. The reserve organization and training mission are described in detail by Army Reserve resources at Army Reserve and unit histories at Fort Leonard Wood.
Modern role and notable deployments
As a Training Support Division the 75th provided instruction, collective training exercises, and mobilization support. Elements of the division were called to active duty to train and mobilize other reserve and National Guard units during the early 2000s in support of operations in Iraq and Afghanistan. These mobilizations underscored the shift in many historic divisions from combat formations to essential training and readiness commands that prepare deploying units for contemporary operations.
Legacy and distinctions
The 75th Infantry Division's legacy combines combat service in World War II with a later emphasis on training and readiness. It should not be confused with the modern 75th Ranger Regiment, a separate special operations unit with a distinct lineage and role. The division's campaign honors and later service reflect how Army organizations are reconfigured over time to meet changing strategic needs.
