Oklahoma Military Department

The Oklahoma Military Department is an agency of the state of Oklahoma that serves as the administrative agency for all matters concerning the Oklahoma National Guard. Under the authority and direction of the Governor of Oklahoma as commander-in-chief, the agency is responsible for planning, establishing, and enforcing rules and procedures governing the administration, supply, and training of the Oklahoma National Guard, when not in the active service of the United States, and the Oklahoma State Guard. The Oklahoma Unorganized Militia, those citizens of the United States between 17-70 in Oklahoma, only exists in statute, and is not a "state military force," according to Oklahoma Code. The Department also maintains all state-owned, licensed or leased facilities, including Camp Gruber.

The Adjutant General of Oklahoma, appointed by the Governor with the advice and consent of the Oklahoma Senate, serves as the administrative director of the Military Department and is the military commanding officer of the Oklahoma National Guard.

History
The Military Department traces its history to 1890 when the United States Congress authorized one regiment of organized militia for Oklahoma Territory. Following that authorization, the Territorial Legislature passed a law in 1895 which provided for the organization and development of the Volunteer Militia, which later became the Oklahoma National Guard.

The Oklahoma Military Department was established in 1951 and serves as the administrative agency for all matters concerning the Oklahoma National Guard and other military organizations of the State government.
