31st Engineer Battalion

The 31st Engineer Battalion was originally constituted on 1 July 1940 in the Regular Army and activated at Fort Belvoir, Virginia. During World War II, the battalion served with distinction in the European Theater, participating in campaigns such as Normandy, Northern France, Rhineland, and Central Europe, providing critical engineering support for Allied operations. After the war, the unit was inactivated and later reactivated for subsequent conflicts, including service during the Vietnam War, where it conducted construction, demolition, and support missions. Today, the 31st Engineer Battalion is stationed at Fort Leonard Wood, Missouri, where it serves as a training unit for new Army engineers.
