The 10th Mountain Division (Light Infantry) is a light infantry division in the United States Army based at Fort Drum, New York. Originally constituted as a unique mountain warfare unit, the division was the only unit of its size in the U.S. Army to specialize in fighting in mountainous and arctic conditions, thus earning the division the "MOUNTAIN" tab. Today, the division retains its "mountain" designation for historical purposes and is organized as a light infantry division.
Originally activated as the 10th Light Division (Alpine) in 1943, the division was redesignated the 10th Mountain Division in 1944 and fought in the mountains of Italy in some of the roughest terrain in the country. Following the war, the division was deactivated, only to be reactivated and redesignated as the 10th Infantry Division in 1948. The division first acted as a training division and, in 1954, was converted to a full combat division and sent to Germany before being deactivated again in 1958.
Reactivated again in 1985, the division was designated the 10th Mountain Division (Light Infantry) to historically tie it to the World War II division and to also better describe its modern disposition. Since its reactivation, the division and/or elements of the division have deployed numerous times since. The division has participated in Operation Desert Storm (Saudi Arabia), Hurricane Andrew disaster relief (Homestead, Florida), Operation Restore Hope and Operation Continue Hope (Somalia), Operation Uphold Democracy (Haiti), Operation Joint Forge (Bosnia and Herzegovina), Operation Joint Guardian (Kosovo), and several deployments as part of the Multinational Force and Observers (Sinai Peninsula). Since 2001, the division and its four combat brigades have seen over 20 deployments to both Iraq and Afghanistan in support of Operation Iraqi Freedom and Operation Enduring Freedom, respectively.
