  7-17. Army capabilities at echelon perform different functions that vary with the type of unit, the
  organization of the theater or joint operations area, the nature of the conflict, and the number and types of
  friendly forces committed to the effort. At each echelon, a commander or leader task-organizes available
  capabilities to accomplish the mission. The use of capabilities is carefully planned, to include performing
  risk management. When fighting for intelligence at echelon during each strategic context, the G-2/S-2
  considers several factors, including but not limited to—
  ⚫ The commander’s intent.
  ⚫ The arrangement of friendly units and their capabilities across the OE.
  ⚫ Synchronizing the intelligence effort across echelons to present multiple dilemmas to the threat
  across domains.
  ⚫ Threat strengths, vulnerabilities, organizations, equipment, capabilities, intentions, and tactics.
  ⚫ Considering threat capabilities residing in each domain and dimension.
  ⚫ National, joint, and allied-partner capabilities available.
  ⚫ Friendly capability vulnerabilities and limitations.
  ⚫ Timely information is needed for decision making.
  7-18. Army intelligence supports unified action at all echelons. Higher headquarters actively assist their
  subordinate formations in their fights, not simply attaching them to or assigning them with additional
  capabilities. Commanders and staffs actively avoid becoming so narrowly focused on their echelon’s roles
  and responsibilities that they allow their subordinate formations to fail. Likewise, the G-2/S-2 must be able
  to visualize and synchronize intelligence operations across echelons during each strategic context to ensure
  optimal support across the entirety of the battlefield. MI unit structures and capabilities differ significantly
  across theaters and echelons. For example—
  ⚫ Each theater army MIB-T has different capabilities and varying internal task organization.
  ⚫ The corps expeditionary-military intelligence brigade (E-MIB) is the lowest level with organic
  HUMINT units that can support detainee facility interrogations and CI teams.
  ⚫ Theater armies, corps, and BCTs have MI units—MIB-Ts, E-MIBs, and MI companies,
  respectively—but divisions and battalions do not have organic MI units.
  Note. Combatant commands have OPCON of MIB-Ts and usually place them either under
  OPCON or TACON of the ASCC. Some corps E-MIBs can be task-organized to support divisions
  or even some BCTs.
  7-19. The basic intelligence support provided by the G-2/S-2 and intelligence staff at each echelon is the same.
  What differs is the size, composition, and number of supporting capabilities for the intelligence staff; access to
  higher-level information and intelligence; the number and complexity of the requirements; and the time
  available to answer those requirements. Generally, the higher the echelon, the greater the volume, depth, and
  complexity (for example, detailed intelligence products about threat cyberspace activities) of analysis and
  intelligence production the intelligence staff can perform. Lower-echelon G-2/S-2s and intelligence staffs must
  often depend on higher echelons for certain intelligence products and support. Therefore, the commander and
  staff must understand the intricacies or specifics of the intelligence warfighting function across each echelon.
  Figure 7-2 is a notional depiction of echelon roles and responsibilities in time, space, and purpose.
  7-20. As a strategic context shifts from crisis to armed conflict, a good example of echelon interdependencies
  is setting and opening the theater and deploying intelligence staffs and MI units into the theater. Deployment
  comprises activities and processes required to prepare and move forces, supplies, and equipment to a theater.
  Planning for and executing the activities and processes necessary to deploy intelligence staffs and MI units
  occur from the theater army G-2 and intelligence staff level down to the MI unit platoon level. This also
  exemplifies the need for collaborative planning across echelons, as every echelon has a role in deployment.
  While the theater army G-2, intelligence staff, and MIB-T are responsible for setting the theater, once the
  E-MIB is set in theater, the theater army often tasks the E-MIB commander and staff to assist in setting the
  theater. The E-MIB is often tasked to support the deployment of subsequent MI units into the theater,
  especially in the reception, staging, onward movement, and integration (RSOI) of those units. (For more
  doctrine on Army deployments, see ATP 3-35.)
