Fort Sill is a United States Army post north of Lawton, Oklahoma, about 85 miles (137 km) southwest of Oklahoma City. It covers almost 94,000 acres (38,000 ha).^[2]

The fort was first built during the Indian Wars.^[3] It is designated as a National Historic Landmark^[1] and serves as home of the United States Army Field Artillery School, as well as the Marine Corps site for Field Artillery MOS school, United States Army Air Defense Artillery School, the 31st Air Defense Artillery Brigade, and the 75th Field Artillery Brigade. Fort Sill is also one of the four locations for the Army Basic Combat Training. It has played a significant role in every major American conflict since 1869.^[4]
