Marine Detachment Leavenworth

Marine Detachment Leavenworth was a United States Marine Corps unit stationed at the United States Disciplinary Barracks in Fort Leavenworth, Kansas. Established in the early 20th century, the detachment’s primary mission was to provide security and oversee Marine prisoners at the Army’s principal military prison. Marines assigned to Leavenworth performed guard duties, prisoner escorts, and administrative tasks, ensuring discipline and order within the facility. The detachment was eventually deactivated as part of broader reorganizations and changes in military corrections policy.
