Vuono approved the conversion of the division's two combined arms battalions light to standard mechanized infantry battalions. Inactivation The division was the first to undergo full inactivation following the end of the Cold War. Army leadership at first decided that inactivating units would turn in all of their equipment at "10/20" standard – in ready and reusable condition. The division struggled to meet this standard. It required both extensive work on the part of the division's soldiers and high costs in repair parts. While the remaining 9th ID soldiers were ultimately successful, later inactivating units were not required to attain this goal. The inactivation of the division began on 28 September 1990 with the inactivation of the 1st Brigade, 2nd Battalion, 23rd Infantry, and 4th Battalion, 23rd Infantry. The 1st Battalion, 84th Field Artillery inactivated on 15 January 1991. As inactivation proceeded, elements and individual Soldiers from the division were detached and deployed for service in the Gulf War. On 16 February 1991 the 3rd Brigade was reflagged as 199th Infantry Brigade (Motorized) with the following units: 199th Infantry Brigade (Motorized), Fort Lewis Headquarters & Headquarters Company 1st Battalion, 33rd Armor 2nd Battalion, 1st Infantry 3rd Battalion, 47th Infantry 1st Battalion, 11th Field Artillery 99th Support Battalion (Forward) Troop A, 9th Cavalry (rest of 1st Squadron, 9th Cavalry disbanded on the same date) 102nd Engineer Company (Company D, 15th Engineer Battalion) 9th Chemical Company Battery E, 44th Air Defense Artillery (rest of 1st Battalion, 44th Air Defense Artillery disbanded on the same date) The remainder of the division's units inactivated on the following dates: 15 February 1991: 2nd Battalion, 60th Infantry
