The present state office of adjutant general was established by the Texas legislature in 1905. A similar office existed under the Republic of Texas but was abolished in 1840. It was reestablished as a state office in 1846, but activities were limited to the verification of veterans' land claims. The office operated intermittently from 1846 until 1905. The adjutant general, appointed by the governor for a two-year term, heads the Adjutant General's Department. He is assisted by two assistant adjutants general, who are appointed by the governor upon his recommendation. All three officials must have previous military service and at least ten years' experience as commissioned officers in an active unit of the Texas National Guard. The adjutant general serves as the governor's aide in supervising the military department of the state. Responsibilities include providing military aid to state civil authorities and furnishing trained military personnel from the state's military forces-the Texas State Guard, the Texas Army National Guard, and the Texas Air National Guard-in case of national emergency or war. The Adjutant General's Department is located at Camp Mabry in Austin. In the early 1990s annual working budgets totaled over $14 million.
