  relationship—to the joint task force (through the joint network operations control center) and the theater army
  (through the regional cyber center).
  2-56. The commander, joint task force exercises overall authority and responsibility for DODIN operations
  within the joint operations area. The theater army also provides guidance to Army forces through technical
  channels to ensure compliance with Army policies for DODIN operations. Refer to JP 3-33 for more
  information about joint task force operations.
  SIGNAL COMMAND (THEATER)
  2-57. The SC(T) headquarters at its home station receives communications and information services support
  from its local network enterprise center. Forward deployed SC(T) staff elements receive network and
  information services support through an overseas installation’s network enterprise center or forward
  operating base infrastructure, or request communications support from theater-committed or rotational signal
  units through the geographic combatant commander to United States Army Forces Command.
  Note. In a theater with no assigned SC(T), the strategic signal brigade commander and staff or the
  tactical actions center assume the staff functions normally associated with the SC(T).
  TYPES OF SIGNAL UNITS LEVERAGED FOR SUPPORT
  2-58. The Army’s global force pool includes echelons above core expeditionary signal units to support those
  units with no organic signal assets. Expeditionary signal units can also augment corps and below units when
  organic capabilities are not sufficient for an assigned mission.
  THEATER TACTICAL SIGNAL BRIGADE
  2-59. The theater tactical signal brigade headquarters supervises building, configuration, operation, and
  maintenance of communications nodes, and secures these nodes, in the deployed portion of the network,
  excluding the division and corps systems. It also integrates interorganizational and multinational partners
  into the DODIN. The theater tactical signal brigade—
  * Allocates, controls, and positions tactical networking resources.
  * Oversees connection to the network for Army and designated joint, interorganizational, and
  multinational elements.
  * Provides physical security for, and actively defends, network resources.
  * Performs long-range planning for tactical network expansion and upgrade.
  * Enforces global (enterprise) and theater-level technical standards and policies for assigned tactical
  networking resources.
  * Conducts enterprise systems management and network management.
  * Conducts spectrum management operations for tactical signal forces in theater.
  * Exercises communications-electronics maintenance and logistical readiness oversight over
  subordinate elements.
  * Oversees contractor support operations and personnel.
  Expeditionary Signal Battalion
  2-60. The expeditionary signal battalion is a fundamental building block of the Army’s global force pool.
  Most expeditionary signal battalions are theater available forces that can deploy for contingency or enduring
  missions. An expeditionary signal battalion consists of a headquarters company, two expeditionary signal
  companies, and a joint/area signal company. The battalion headquarters provides administrative and logistical
  support for the signal battalion. The battalion S-3 oversees designing, building, configuring, securing,
  operating, maintaining, and sustaining nodal and extension communications.
