United States Army Field Artillery School in the context of "Fort Sill"

Fort Sill is a major United States Army post north of Lawton, Oklahoma, approximately 85 miles (137 km) southwest of Oklahoma City, established in 1869 during the Indian Wars. It covers almost 94,000 acres (38,000 ha) in southwestern Oklahoma and serves as headquarters of the U.S. Army Fires Center of Excellence. The installation is a Basic Combat Training facility, training over 20,000 personal annually in field artillery, air defense artillery, and electronic warfare.

Fort Sill has participated in every major U.S. conflict since its founding, evolving from a frontier cavalry outpost to a modern training hub. It houses key units including the United States Army Field Artillery School, 75th Field Artillery Brigade (United States), and the 31st Air Defense Artillery Brigade (United States). The post also supports a United States Marine Corps detachment for joint artillery training.
