Okla. Stat. tit. 44, § 21.1
Personnel appointed as state employees in the Military Department shall be in the classified service of the state, except as otherwise provided by law, and shall be subject to the provisions of the Oklahoma Personnel Act concerning appointments, promotions, adverse actions, and all other personnel matters. However, the Adjutant General may establish a requirement for membership in the National Guard as a special requirement for appointment to, and continued employment in, certain positions in the classified service which require special military training, exercise of command authority, direct specified military programs, or perform other functions directly related to administration and training of the National Guard or the maintenance or repair of National Guard facilities, equipment, or supplies. Such designated positions shall include the specified military grade or grades authorized by the Adjutant General for appointment to the position and continued employment therein. An employee in a designated position who is separated from the National Guard or who does not hold the specified military grade for the position will be reclassified, promoted, demoted, transferred or separated in accordance with the provisions of the Oklahoma Personnel Act and the Merit Rules for Employment.
