Fort Sill Army Base in Lawton, OK Oklahoma Military Bases


Fort Sill, OK merged with artillery units from Fort Bliss, TX in 2011 as an outcome of the 2005 BRAC (Base Realignment and Closure Commission), retaining the name and increasing their population by 10,000. Home to the Field Artillery Training Command, Fort Sill is located in Comanche County, Southwest Oklahoma, adjacent to the city of Lawton and 90 miles Southwest of Oklahoma City. All soldiers in Field Artillery receive skills training at Fort Sill. US Marines and international students from allied nations are also trained there. Nearby geographical destinations include Quartz Mountain Resort and Conference Center near Lone Wolf, Chisholm Trail Heritage Center in Duncan, and Indian City USA in Anadarko.


Military first came to Comanche County in 1834. In 1851 Captain Randolph Marcy first suggested building a fort. Following the Civil War, Colonel Benjamin Grierson and the Buffalo Soldiers constructed the old post site named Camp Wichita in 1868. In 1869 permanent buildings were erected and the name changed to Fort Sill. It is the namesake of Brigadier General Joshua Sill, a West Point graduate killed at the battle of Stones River, TN in 1862. Fort Sill maintains the holding cell and grave of Chief Geronimo, the famous Chiricahua Apache warrior.

Throughout the 20th Century Fort Sill expanded and by 1930 became the permanent home of Field Artillery, including Army missile and atomic warhead training. The soldiers fired a live atomic round at Frenchman’s Flat, NV in 1953; the only time live atomic artillery was ever tested. By the early 21st Century Fort Sill’s reservation included Henry Post Army Air Field and Reynolds Army Community Hospital.

Soldiers from Fort Sill have supported all major military engagements at home and around the world from the 1860s through to today’s Afghanistan operations.


As the artillery training center for the US Army and Marines they train day and night to put “steel on target.” Fort Sill’s approach to training and preparedness makes it one of the best Army training posts and the largest field artillery complex in the free world. The two major commands are FORSCOM (Forces Command) and TRADOC (Training and Doctrine Command).
