Organization and Mission of the USASC

Headquarters, USASC is the Army's CONUS-based, worldwide signal force and service provider. It supports the CONUS-centric Army's force projection mission through its integrated, worldwide deployable theater tactical units, strategic and sustaining-base units, and global network and systems management. USASC also supports the Army's forward presence through its operator-based operation and maintenance of European, Korean, Pacific, Central America, and Southwest Asia strategic, theater tactical, and sustaining-base signal support systems and units.


3-1. The USASC is the Army's senior, worldwide operational signal command providing strategic and operational (through MSCs) signal support both CONUS and outside continental United States (OCONUS). Figure 3-1 shows the USASC under the C2 of the US Army Forces Command (FORSCOM). The USASC commander also serves as the Deputy Chief of Staff for command, control, communications, and computers (DCSC4) of FORSCOM. USASC TOE provides a deputy commander to oversee the DCSC4 functions, with the remainder of the DCSC4 staff on FORSCOM's personnel authorization documents.

3-2. The assigned missions of the USASC range from operational to strategic/ sustaining-base. The USASC is responsible for the operation and maintenance (O&M) of the Army's portion of the DISN. Therefore, subcommands are required to provide operational reports to DISA as required in accordance with (IAW) DISA regulations on matters pertaining to the DISN. The USASC is responsible for supporting other US forces as directed or as formalized by interservice support agreements and JCS tasking. The USASC has Executive Agency missions to include, but not limited to:

  • DSCS.
  • Defense Red Switch Network (DRSN).
  • Automatic digital network (AUTODIN) to Defense Message Switch (DMS).
  • Defense Information Infrastructure [DII] (NIPRNET/SIPRNET).
  • DII (microwave/fiber optics cable).

3-3. In today's world environment, the USASC provides signal support in support of MOOTW. The USASC must be flexible and versatile enough to provide support to US national interests worldwide.

3-4. The USASC is structured in two entities: rear and forward. The rear section, lead by the commanding general (CG), is expected to remain in CONUS and provide the expertise, guidance, and command to units forward deployed. The forward section, under the deputy commander, is deployed in those contingencies other than a major theater war (MTW). It will provide the necessary signal expertise or augmentation to a corps-based JTF or JFLCC not supported by a TSC.


3-5. In MOOTW outside a TSC's AOR, USASC performs the warfighter information responsibility at the operational level for all US forces as assigned. The support is provided by the forward element of the USASC. The forward element commands and controls all EAC signal elements deployed to MOOTW AOR.


3-6. The primary mission of the USASC is the command of its MSC, the TSC that supports the ASCC. The TSC is under the OPCON of the ASCC. The commander of the TSC also serves as the G6 of the ASCC. The TSC commands and controls all assigned EAC signal units in theater. The USASC provides general support to the TSC in the TSC's support role for the ASCC and the ARFOR commander's concept of operations and priorities. The USASC also provides DISN restoration support and tactical signal augmentation to the TSC, using CONUS-based tactical, strategic, and power projection platforms assets. See Appendix A for detailed information on this command.

3-7. The USASC--

  • Provides the organizational structure and professional and technical personnel to staff a headquarters for support of an Army signal command.
  • Provides C2 and supervision of all assigned and attached personnel.
  • Commands and controls the Army portion of the DISN.
