On the disbandment of the 163rd Armored Brigade, the 1st Battalion, 163rd Infantry was reassigned to the 116th Cavalry Brigade headquartered in Idaho. 'Commonly referred to as the Griz Battalion, the 1-163rd at first was designated as a Cavalry Regiment in 1953, named the 163rd Cavalry Regiment. The unit was renamed the 1-163rd Infantry Battalion during the 2006 reorganization of the Montana Army National Guard, and was re-designated as Cavalry once again in 2007, combining mechanized infantry with Abrams tank units.' In the 2006 reorganization, the 1st Battalion, 190th Field Artillery at Billings became the 190th Combat Service Support Battalion.
