  and multinational air and missile defense forces combine to form integrated defenses after completion of
  deployment operations. Echelon commanders, with staff support, designate their echelon priority assets. The
  JFC and joint staff take these echelon priority asset lists into consideration during the development of an
  adjusted JTF defended asset list. JFC’s requirements and mission considerations may allow for an air defense
  artillery brigade to be placed under operational or tactical control of a corps. Support relationships, such as
  direct and general support, may also be used to enhance air and missile defense of maneuver echelons. Corps
  and divisions (when further delegated) may integrate air defense artillery firing units and radars into their
  defense plans, ensuring that they integrate into local security measures. At the division level, the air defense
  artillery brigade units complement the division’s organic short-range air defense forces. (See FM 3-01 for
  additional information on Army air defense artillery operations.)
  Civil Affairs Brigade
  4-70. A civil affairs brigade provides a civil affairs capability to joint force and land component commanders.
  The civil affairs brigade mitigates or defeats threats to civil society and conducts actions normally performed
  by civil governments across the range of military operations. This occurs by engaging and influencing the
  civil population and authorities through the planning and conducting of civil affairs operations or enabling
  civil-military operations to shape the civil environment and set the conditions for military operations.
  4-71. The civil affairs brigade headquarters provides a control structure and staff supervision of the
  operations of its assigned civil affairs battalions or other attached units. Civil affairs force structure contains
  expertise in five functional specialty areas. These specialty areas include security, justice and reconciliation,
  humanitarian assistance and social well-being, governance and participation, and economic stabilization.
  Within each functional specialty area, civil affairs functional specialists advise commanders and help or direct
  their civilian counterparts. Civil affairs brigades are capable of establishing or support civil-military
  operations centers during operations. (See FM 3-57 for additional information on civil affairs.)
  Chemical, Biological, Radiological, and Nuclear Brigade
  4-72. A CBRN brigade typically provides support to a corps and echelons above corps. However, in some
  instances, the brigade may also support a division. When a CBRNE command is deployed, it may command
  a CBRN brigade. CBRN brigades consist of a headquarters and two to five battalions with a wide range of
  CBRN capabilities, including CBRN reconnaissance, decontamination, and biological detection. With the
  advice of the staff and the supported unit CBRN section, the CBRN brigade commander evaluates and
  determines the CBRN unit support requirements for the supported unit. The brigade commander may advise
  the supported unit commander about the employment and sustainment of CBRN assets. A CBRN brigade is
  dependent on other organizations for administrative, logistic, medical, and maintenance support. In some
  instances, a division, corps, or echelon above corps may only be assigned or supported by a CBRN battalion.
  (See FM 3-11 for more information on CBRN units.)
  Explosive Ordnance Disposal Group
  4-73. An EOD group may be attached or under the operational control of a CBRNE command, corps, or
  echelons above corps conducting large-scale combat operations or limited contingencies operations such as
  Task Force Atlas in Operation INHERENT RESOLVE and Task Force Paladin in Operation ENDURING
  FREEDOM. An EOD group commander exercises command and control of two to six explosive ordnance
  disposal battalions. An EOD group may be task-organized with forces from other Services. An EOD battalion
  conducts staff planning and control of EOD assets typically within a division AO. EOD groups and battalions
  position their EOD companies at locations where they can best provide support throughout an AO. (See
  ATP 4-32.1 and ATP 4-32 for doctrine on explosive ordnance disposal.)
  Psychological Operations Battalion
  4-74. Psychological operations battalions are trained, organized, and equipped to support corps- or division-
  level operations. They support corps with military information support operations across the range of military
  operations. They can also support the staffing and augmentation of a psychological operations task force in
  a mature theater of operations. The tactical psychological operations companies are task-organized to support
  divisions. (See FM 3-53 for more information of military information support operations.)
