was brief; in 1952 the division was once again redesignated the 100th Infantry Division. It would change names again in 1955, this time to 100th Division (Replacement Training). It would once again be reorganized in 1959 to its present designation as 100th Division (Institutional Training). Its mission became to teach basic, advanced, and common training skills to soldiers from the Army's active, reserve, and National Guard components. In 1961, some 1,500 soldiers from the 100th were activated and sent to Fort Chaffee, Arkansas, in order to provide support during the Berlin Crisis. During their time on active duty, the 100th successfully trained some 32,000 soldiers after thoroughly rebuilding and fixing the old Army base. The unit was returned to reserve status again in August 1962. In 1968, the division received its distinctive unit insignia, which alluded to its history in World War II and as a Kentucky-based unit. With the Reorganization Objective Army Division plan in 1968, the division ceased to be centered on regiments and instead was reorganized with brigades. However, with the 199th Infantry Brigade active as a separate brigade, the division's new brigades were activated from units that had been under its command in World War II. The division's headquarters element (which had since been replaced by a Headquarters and Headquarters Company) was redesignated the 1st Brigade, 100th Division responsible for basic armor school training. The 928th Field Artillery Battalion became the 2nd Brigade, 100th Division responsible for armored cavalry unit training. The 325th Engineer Battalion became the 3rd Brigade, 100th Division responsible for combat support training, and the 800th Ordnance Battalion became the 4th Brigade, 100th Division, responsible for combat service support training. In 1978, the 100th became the first Army Reserve formation to be equipped with its own squadrons of M1 Abrams tanks. With the arrival of the M3 Bradley infantry fighting vehicles, the division's mission profile changed from individual combat training to armor and armor reconnaissance training. By 1986, it was the largest reserve unit within the state of Kentucky, commanding fifty-eight percent of instate reservists. Gulf War and beyond At the outbreak of Operation Desert Storm in 1991, the 100th was assigned to armor training at Fort Knox, Kentucky for deploying armor units. Armor training was a responsibility that the division continued after the war. In 1995 the division was reorganized to include Army Reserve schools, taking over the responsibilities for new programs.
