636th Military Intelligence Battalion
(Combat Electronic Warfare Intelligence)

On April 15, 1999 eleven Texas Army National Guard units were officially notified that they should begin training for a possible mobilization and deployment to Bosnia as part of the NATO Stabilization Force. The units included the 649th Military Intelligence Battalion, Austin, Texas.

The distinctive unit insignia was approved on 10 October 1996, consisting of a shield blazoned: Per bend Argent (Silver Gray) and Azure (Oriental Blue), a griffin's head erased Sable and a mullet Argent. Attached below the shield a Black scroll doubled and inscribed "LONE STAR VIGILANCE" in Silver. Oriental blue and silver gray are the colors traditionally used by Military Intelligence. The griffin embodies vigilance, alertness and courage, reflecting the unit's motto and mission. Black and white symbolize overt and covert operations and the night and day, twenty-four hour mission of Military Intelligence. The star highlights the motto and represents the home area of the battalion, Texas.

On May 1, 2004, the 49th Armored Division was officially inactivated and the 36th Brigade of the 49th Armored Division was redesignated the 36th Infantry Division. Reflecting this change, the 649th Military Intelligence Battalion was reflagged as the 636th Military Intelligence Battalion.
