In October 2004, the 84th Division (Institutional Training) underwent a major transformation. All eight brigades realigned under the 100th Division and the Headquarters and Division Band combined with the Army Reserve Readiness Training Center (ARRTC) located at Fort McCoy, Wis., to create the 84th U.S. Army Reserve Readiness Training Command (84th USARRTC). The expertise and resources from the two units gave the 84th USARRTC an edge on the type and amount of training opportunities offered. The three Army Reserve NCO academies were also realigned under the new 84th USARRTC.
