  3-100. The theater army depends on the Army Materiel Command for support through the Army field
  support brigade, contracting support brigade, and logistics civil augmentation program. The Army field
  support brigade provides national-level, materiel-focused sustainment support and logistics civil
  augmentation program planning and management. The contracting support brigade provides operational
  contract support and planning assistance.
  3-101. The theater army also depends on several unique teams to accomplish specialized functions. Defense
  Logistics Agency personnel provide the theater army logistics reach to the national supply system. Public
  affairs detachments or teams augment the organic theater army staff and establish a media support or
  broadcast center, if required. An Army band is assigned to the theater army to enhance unit cohesion and
  Soldier morale and provide musical support. The theater army depends on the human resources sustainment
  center and financial management support center of the TSC for the execution of specified personnel and
  finance and comptroller activities. Digital liaison detachments provide liaison between the theater army and
  multinational headquarters or partners during operations and exercises.
  3-102. The theater army depends on the Army Corps of Engineers for engineering and construction
  (including roads and buildings), real estate, and environmental management products and services.
  3-103. The supporting criminal investigation division detachment provides protective service details for the
  theater army commander, deputy commanders, and other designated high-risk personnel, as required. A force
  protection team assists the theater army antiterrorism or force protection section in protection, physical
  security, antiterrorism, and response force operations.
  JOINT THEATER ENABLERS
  3-104. If the theater army assumes an operational headquarters role as a JTF or JFLCC, the combatant
  commander provides it with joint enablers. The Joint Enabling Capabilities Command of the
  USTRANSCOM provides mission-tailored, joint capability packages to combatant commanders to facilitate
  rapid establishment of joint force headquarters, fulfill global response force execution, and bridge joint
  operational requirements. This command includes the joint planning support element, joint communications
  support element, and joint public affairs support element. The joint planning support element provides rapidly
  deployable, tailored joint planners, operators, logisticians, knowledge managers, and intelligence specialists.
  The joint communications support element provides rapidly deployable, en route, early entry, and scalable
  command, control, communications, computer, ISR capabilities across the range of military operations. The
  joint public affairs support element provides a ready, rapidly deployable joint public affairs capability to
  combatant commanders. (See JP 3-61 for more information on joint theater enablers.)
  THEATER ARMY IN COMPETITION
  3-105. During competition, the theater army supports the GCC in conducting missions, tasks, and actions
  that shape the environment to assure friends, deter adversaries, and establish conditions for future
  contingencies. To accomplish this, the theater army, as the ASCC, executes GCC daily operational
  requirements while training and preparing for future contingency operations.
  3-106. Executing operational requirements prepares the ASCC to rapidly transition to conflict should the
  GCC identify an increased threat and an operational requirement in an AOR. Well in advance of any conflict,
  the theater army ensures the ARFOR/JFLCC’s targeting desires are represented during the development of
  the modernized integrated database and the resulting joint target list, restricted target list, and no-strike list.
  Should the GCC identify a potential crisis, the theater army examines a range of basing and deployment
  options. When the combatant commander decides on specific deterrent options, the theater army begins the
  process of recommending, requesting, and tailoring landpower. This is done while refining plans for the full
  employment of landpower should deterrence fail to resolve the crisis.
  3-107. As soon as feasible, Army forces attached to the theater deploy and the theater army receives, stages,
  and integrates additional Army forces into an AO. To accomplish this, the theater army develops additional
  basing requirements. As Army forces deploy into a JOA, the theater army expands its footprint to sustain and
  protect Army, joint, and multinational forces, as directed by the GCC.
