In 1996 the 100th Division's 1st Brigade worked with Readiness Group Knox to pioneer the national training experiment to reserve combat units at crew and platoon levels. Later that year, the division added three additional divisional brigades; the 5th Brigade, 100th Division in Memphis, Tennessee for health services training, the 6th Brigade, 100th Division in Louisville, Kentucky for professional development training, and the 7th Brigade, 100th Division at Fort Knox, formed from the 100th Training Command and responsible for training exercises. The 5th Brigade moved to Millington, Tennessee in 1997, and the 7th Brigade inactivated in 2000. The 8th Brigade, 100th Division was also activated as a unit overseeing ROTC training. During 1997, the division was tasked with partial responsibility for Operation Future Challenge at Fort Knox, a six-week Reserve Officer's Training Corps Basic Camp during each summer. By 2000, the 100th has assumed full responsibility for running the camp. Later that same year, the 100th began inactivating many of its M1A1 Abrams tanks as part of a reduction in military expenditures. After the September 11 attacks, the 100th Division began taking on the job of preparing Army National Guard units from Ohio and Kentucky as they began to prepare for deployment in support of the War on Terrorism. By 2006, the division had moved its headquarters from Louisville to Fort Knox, easing distance strains in administration and training. In line with Army Reserve transformations, the 100th Division restructured, eliminating all but four of its brigades. The division shifted its focus from initial entry training to providing military occupational specialty and non-commissioned officer training for four army career fields across the United States. The 100th Division (Operational Support) teaches soldiers subjects from military intelligence, signal corps, civil affairs/psychological operations and health services. On 1 October 2018 the 100th Training Division was redesignated as the 100th Training Division (Leader Development). The 100th Training Division (Leader Development) establishes and implements the Army Reserve Leader Development Strategy to provide a continuum of career education, training, and experience for leaders in the Army Reserve. During this reorganization, the 83rd USARRTC and the 97th (CGSOC) Brigade were placed under the 100th Training Division.
