Texas Army National Guard

The Texas Army National Guard has its roots in the Texas Militia formed by Stephen F. Austin at his headquarters village of San Felipe de Austin. Austin was empowered to "organize the Colonists into a body of National Militia" in the 18 February 1823 decree authorizing Austin to form his colony in Mexican Texas. Commissioned as Lieutenant Colonel, Austin organized the 5-company battalion at San Felipe de Austin on 22 June 1824. Three companies were formed on the Brazos River and two on the Colorado. This militia structure formed the basis for several of the volunteer companies raised to fight in the Texas Revolution of 1836.{} The Militia Act of 1903 organized the various state militias into the present National Guard system. After World War II, the Texas National Guard was reorganized with the 36th Infantry Division and the new 49th Armored Division. The 49th Armored Division was ordered to active federal service in October 1961 at Dallas, for the 1961 Berlin Crisis, and reverted to state control in August 1962. The 36th Airborne Brigade was active from 1973, and inactivated on 1 April 1980. In November 1976 the Texas Army National Guard, in the words of the AG Report 1975-76, was "organized into a State Headquarters and Headquarters Detachment, Public Information Detachment, the 49th Armored Division, and the Base Units Command of the State," both commanded by general officers. The 49th Armored Division had its headquarters in Austin; comprised three brigades, divisional artillery, and a Division Support Command; and was authorized a strength of 14,854 officers, warrant officers, and enlisted men. Its units were spread geographically across the entire state. The Base Units Command commanded every other unit in the TX ARNG except the division and the 100th Public Information Detachment. It consisted of one support center headquarters, one airborne brigade headquarters [the headquarters of the 36th Airborne Brigade)], one aviation group headquarters (111th), one support group headquarters, three battalions, one engineer dredge detachment, one assault support helicopter company, one air ambulance medical company, and one Combat Support Hospital (117th), with an authorized strength of 2,603 officers, warrant officers, and enlisted personnel (p. 5). The 36th Brigade was reconstituted as a divisional formation (36th Brigade, 50th Armored Division) from 1988–92. In 1992 it became the 36th Brigade of the 49th Armored Division based at Houston, TX. It seems likely to have been active between 1992 and May 2004 when the 49th Armored Division became the 36th Infantry Division. == Organization ==
