The 85th Infantry Division also known as "Custer Division" (named after the cavalry commander George Armstrong Custer) was an infantry division of the United States Army in World War I and World War II. It currently exists as the 85th Support Command. World War I The division was first activated 25 August 1917 at Camp Custer, Michigan, and comprised the 169th and 170th Infantry brigades and the 160th Field Artillery Brigade. After a year of training the division left the United States for England. The Division was composed of the following units: Headquarters, 85th Division 169th Infantry Brigade 337th Infantry Regiment 338th Infantry Regiment 329th Machine Gun Battalion 170th Infantry Brigade 339th Infantry Regiment 340th Infantry Regiment 330th Machine Gun Battalion 160th Field Artillery Brigade 328th Field Artillery Regiment (75 mm) 329th Field Artillery Regiment (75 mm) 330th Field Artillery Regiment (155 mm) 310th Trench Mortar Battery 328th Machine Gun Battalion 310th Engineer Regiment 310th Field Signal Battalion Headquarters Troop, 85th Division 310th Train Headquarters and Military Police 310th Ammunition Train 310th Supply Train 310th Engineer Train 310th Sanitary Train 337th, 338th, 339th, and 340th Ambulance Companies and Field Hospitals From England the 339th Infantry Regiment sailed to Archangel, Russia to fight along the White Army in the Russian Civil War against Bolshevik forces as part of the Polar Bear Expedition. Accompanying the 339th were the 1st Battalion, 310th Engineers, the 337th Ambulance Company, and the 337th Field Hospital. After arrival in France as part of the American Expeditionary Forces, the remainder of the division was broken up to support other units. The Headquarters was stationed in Lorraine as a depot division and therefore did not participate in any combat operations.

After the war the division remained on occupation duty in Germany and by August 1919, the last elements of the division returned to the United States.
