American Military History, Volume 2 by Richard W. Stewart

After Vietnam the Army underwent a number of organizational changes at the higher headquarters and tactical levels. At the highest level the Army determined to reorganize its command structure for the continental United States (CONUS) and separate its essentially com- mand and control headquarters from its training base.

Following World War II, the Army had organized its operational forces in CONUS under six U.S. armies, each with a geographic area of responsibility. The chiefs of the Army's technical services retained responsibility for depots and other specialized facilities and activities that reported directly to them. In 1955 the Army established the U.S. Continental Army Command (CONARC) to command and control the six armies in CONUS and their subordinate operational forces and in 1962 created the Army Materiel Command (AMC) and the Combat Developments Command (CDC) to manage force development and control the technical services. Over the years, CONARC's control ex- panded to most Army schools and the various branch boards involved with Army combat developments, the Reserve Officers Training Corps (ROTC), the U.S. Army Reserve, and support for the Army National Guard. CONARC was a multifunctional Army major command (MA- COM) responsible for active and reserve component force readiness, collective training, individual training, recruiting, and officer procurement.
