ACES holds a current sustainment contract with the United States Army Medical Command (MEDCOM) to provide administration and continuing refinement of the MEDCOM Network Access Control (NAC) deployment. This worldwide deployment consists of 5 main command and control sites with numerous satellite sites connected. As the Army Medical Command transitions to the control and administration of the Defense Health Agency (DHA), ACES will continue to support not only the existing NAC solution, but ensure a smooth transition and operability for DHA as their mission requirements dictate.
