About this Unit
Fort Sill, located in southwest Oklahoma, was established in 1869 during the Indian Wars to protect settlers and serve as a base for military campaigns against the Southern Plains tribes. Named after Brigadier General Joshua W. Sill, the fort played a pivotal role in the settlement of the American West and later became home to legendary figures like Geronimo and Buffalo Soldier regiments. In the 20th century, Fort Sill evolved into the premier training center for the U.S. Army’s Field Artillery branch, earning the moniker "Home of the Field Artillery." Today, it continues to serve as a vital training and operational hub, supporting both Field Artillery and Air Defense Artillery missions for the U.S. Army.
