HHC 63d ARCOM

The Headquarters and Headquarters Company, 63d Army Reserve Command (HHC, 63d ARCOM) was a key administrative and command element for the 63d ARCOM, which was established to oversee Army Reserve units in the southwestern United States. Activated in 1968 and headquartered in Los Alamitos, California, the 63d ARCOM provided command and control, training, and mobilization support for assigned Army Reserve units during the Cold War era and beyond. The unit played a significant role in preparing reserve forces for federal activation, supporting both national emergencies and overseas deployments. In the 1990s, the 63d ARCOM was reorganized and eventually redesignated as the 63d Regional Support Command, reflecting broader changes in Army Reserve structure and mission focus.
