83rd United States Army Reserve Readiness Training Center

In 1975 an Army Inspector General found that the two administrative Supply Technician schools located in Columbus, Ohio and Fort McCoy, Wisconsin were teaching different courses of instruction. These schools were aligned under the Civilian Personnel Office at their respective locations.

In 1976 FORSCOM (Forces Command) decided to combine the two schools together and formed the Army Reserve Technician Training Center (ARTTC). Fort McCoy was chosen to be the site for the new ARRTC due to its central location in the United States. The school had a completely civilian staff until 1981. At that time a new program was instituted by the Army called the Active Guard/Reserve (AGR) program. AGR Soldiers were then assigned to the ARTTC.

In 1982 ARTTC becomes the Army Reserve Readiness Training Center (ARRTC) and also becomes a tenant activity of Fort McCoy. Col. Don Smith becomes first full-time, permanent military commandant of the school. The ARRTC was designed to specifically train Army Reserve personnel and it consisted of six training centers. Each of the training centers had its own specialization: Mobilization and Movement; Training and Operations; Human Resource Management; Logistics and Engineering; Security, Resource and Information Management; and Retention and Entry Training. In 1992 a new administrative, classroom and dining facility is built and occupied. ARRTC launched its distributive learning program in 1997. 2000 saw the ARRTC dormitory, building 51, opened. This project connects the new dormitory to administrative and classroom facility.

The ARRTC celebrated its 25th anniversary in 2001. By 2005, the curriculum had expanded to teach not only Army Active, Reserve and Army National Guard Soldiers and civilians, but also Department of Defense Civilians along with members of the Active and Reserve Components for the Air Force, Navy, and Marine Corps.

During the 2004 Base Realignment and Closure Commission, the ARRTC was identified to relocate from FT McCoy to FT Knox. In May 2005, the unit was consolidated with the 84th Division (Institutional Training) and redesignated as the 84th United States Army Reserve Readiness Training Center (USARRTC) with headquarters split between Fort McCoy and Milwaukee, Wisconsin.

On October 1st, 2009, the United States Army Reserve Command remissioned the 84th Training Command from Leader Readiness to Unit Readiness. In doing so, the ARRTC (Provisional) was reformed from elements of the 84th Training Command (Unit Readiness). On 17 December 2009, the Chief of the Army Reserve re-designated the 4-339th Regiment as the ARRTC (Prov) and named COL Robert Felland as the Commandant. One year later, the ARRTC was placed as a direct reporting to USARC with staff oversight from the Deputy Chief of Staff, G 3/5/7. The assumption of command of COL Aaron Walter signifies the completion of the ARRTC transition from provisional status.

In accordance with BRAC law, the ARRTC will start moving to FT Knox, KY in November 2010 and will complete the move no later than September 15, 2011.
