  operations. A degraded support area also inhibits the ability to shape the corps deep area for divisions
  involved in the corps’ close operations. Therefore, corps support area operations requires planning
  considerations equal to those in the corps close areas. (See FM 3-81 for additional information on MEB
  operations.)
  Expeditionary-Military Intelligence Brigade
  4-52. The Army has three Regular Army expeditionary-military intelligence brigades (E-MIBs) in its force
  structure, each assigned to a corps headquarters, and two expeditionary-military intelligence brigades in the
  Army National Guard and two in the Army Reserve. The E-MIB provides intelligence capability and capacity
  to the corps and subordinate divisions. This facilitates situational understanding for the corps and division
  commanders and critical pieces of the sensor-to-shooter linkage necessary for the corps to execute shaping
  operations in the corps deep area.
  4-53. The E-MIB is designed to receive, integrate, employ, and sustain intelligence capabilities and
  capacities in the corps AO and to provide support to subordinate divisions. The nature of this support to the
  corps is enhanced capability and capacity in intelligence analysis, processing, exploitation, and
  dissemination, multi-domain collection capability, human intelligence, and counterintelligence collection
  and processing capability. The E-MIB does not conduct reconnaissance.
  4-54. The corps commander retains control of the E-MIB and task-organizes elements, generally one
  intelligence and electronic warfare (IEW) battalion, of the E-MIB to divisions as required. The IEW battalion
  (at corps echelons), organic to the E-MIB, remains with the corps headquarters and provides one detachment
  of analysis and processing, exploitation, and dissemination to the corps assistant chief of staff, intelligence
  (G-2), one detachment of multi-domain collection capabilities, and one company of human intelligence, and
  counterintelligence collection and processing capability in support of corps multi-domain operations.
  4-55. One E-MIB is assigned per corps or field army. The E-MIB staff works closely with the corps G-2
  analysis and control element. The expeditionary-military intelligence brigade commander and staff also assist
  the corps commander in information collection management. E-MIBs are organized with a headquarters, one
  IEW battalion (at corps echelon), and one IEW battalion (at division echelon) per division. The IEW battalion
  (corps) provides general support counterintelligence and human intelligence capability to the corps. Both
  IEW battalions (corps and division) provide direct support analysis as well as processing, exploitation, and
  dissemination to their respective G-2s, and multi-domain sensing and target development capability in
  support of multi-domain operations. The headquarters is responsible for the training and readiness of the
  assigned IEW battalions and can be deployed to serve as the senior military intelligence mission command
  headquarters for field armies or other deployed operational Army headquarters. (See ATP 2-19.3 for more
  discussion of E-MIB capabilities and operations).
  Field Artillery Brigade
  4-56. A field artillery brigade’s primary task is conducting corps-level strike operations and augmenting
  division-level shaping operations. It is capable of employing Army indirect fires and incorporating electronic
  warfare. In addition, a field artillery brigade can request joint fires and coordinate with Army airspace
  elements. The field artillery brigade can detect and attack targets using a mix of its organic target acquisition
  and fires capabilities, a supported organization’s information collection capabilities, and access to higher
  echelon headquarters information collection capabilities.
  Note. A corps conducting large-scale combat operations requires two field artillery brigades. One
  field artillery brigade serves as the counterfire headquarters and the other is the corps force field
  artillery headquarters.
  4-57. Field artillery brigades are typically the force field artillery headquarters for the formation to which
  they are aligned. The brigade commander is designated as the corps fire support coordinator, allowing them
  to better facilitate fires and targeting for the corps. However, in the case where there are two field artillery
  brigades assigned, attached, or OPCON to the corps and no operational-level field artillery command, the
  corps will employ the corps fires support element as the force field artillery headquarters. In this case, one
