The 313th Military Intelligence Battalion, known as the "Crimson Dragons," was an active-duty airborne military intelligence unit of the United States Army, assigned to the 82nd Airborne Division. Its lineage traces back to the 215th Signal Depot Company, activated on September 25, 1942, at Camp Livingston, Louisiana. During World War II, the 215th participated in the Normandy landings, providing critical communications support to field units. Post-war, the unit underwent several reorganizations, eventually becoming the 313th Army Security Agency Battalion during the Vietnam War, where it conducted signals intelligence and electronic warfare operations.
In the subsequent decades, the battalion continued to evolve, integrating various intelligence disciplines to support the 82nd Airborne Division's operations. It participated in numerous conflicts and operations, including Operation Urgent Fury in Grenada, Operation Just Cause in Panama, and Operations Desert Shield and Desert Storm in the Middle East. The 313th was recognized as the Army's most decorated military intelligence battalion. However, in 2006, the battalion was inactivated as part of the Army's transformation initiatives.
