The Texas State Guard (TXSG) is one of three branches of the Texas Military Forces. Along with the other two branches, the TXSG falls under the command of the Texas governor and is administered by the adjutant general, an appointee of the governor. The other two branches of the Texas Military Forces are the Texas Army National Guard and the Texas Air National Guard.
The mission of the Texas State Guard (TXSG) is to provide mission-ready military forces to assist state and local authorities in times of state emergencies; to conduct homeland security and community service activities under the umbrella of Defense Support to Civil Authorities; and to augment the Texas Army National Guard and Texas Air National Guard as required.
Headquartered at Camp Mabry in Austin, Texas, the TXSG functions as an organized state militia under the authority of Title 32 of the U.S. Code and Chapter 431 of the Texas Government Code.
