text: Corps Roles, Functions, and Organizations
  U.S. Air Force Support
  4-75. Air support is vital to the conduct of successful corps operations, regardless of the corps' assigned role.
  The corps depends on joint fires and maneuver provided by fixed-wing aircraft to support many of the corps'
  decisive, shaping, and sustaining operations to include the USAF air functions of close air support, air
  interdiction, cyberspace and electromagnetic activities, and airlift missions. The USAF interface with a corps
  depends on the corps' role. As a tactical headquarters, a corps receives an enhanced corps tactical air control
  party (Note. this level of support does not enable airspace control from the corps level like the joint air ground
  integration center [JAGIC] at the division. Depending on mission environment should the need arise to have
  an air support operations center at the corps, this document does not adequately provide information to enable
  that configuration.). As a JTF or land component command in a limited contingency operation, the corps
  headquarters also receives a joint air component coordination element as its USAF interface.
  Army Space Support Team
  4-76. If requested, an Army space support team can be tasked to augment the corps organic space support
  element if the corps is serving as a JTF or land component command headquarters. (See FM 3-14 for more
  information on the corps space support element ) The Army space support team plans, coordinates, and
  analyzes space-enabled capabilities, and provides input to the corps staff. (See ATP 3-14.3 for more
  information on the space brigade).
  Military History Detachment
  4-77. Military history detachments are small teams of officers and enlisted Soldiers that carry out directed
  collection of historical material during combat and contingency operations for use when writing official
  history. They are trained and equipped to gather historical documents and materials, conduct oral interviews,
  photograph events, and advise supported units about preserving historical information. The military history
  detachment provides expertise, advice, and assistance to the corps command historian. (Refer to ATP 1-20
  for more details on the military history detachment).
  Mobile Public Affairs Detachment
  4-78. A mobile public affairs detachment provides public affairs support to corps units during operations. A
  mobile public affairs detachment is assigned, attached, or under the OPCON of echelons above brigades. It
  may support the ASCC, theater sustainment command, or corps public affairs staff sections.
  4-79. A mobile public affairs detachment increases the public affairs capabilities of the corps organic public
  affairs section. A mobile public affairs detachment can establish or support a media operations center to
  support corps operations. A mobile public affairs detachment has limited capability to conduct independent
  public affairs activities and requires higher echelon command guidance, administrative support, and life
  support. Because of its limited capability, the corps public affairs officer exercises planning and supervisory
  authority over the mobile public affairs detachment. (Refer to FM 3-61 for more details on public affairs
  operations.)
  Cyberspace and Electromagnetic Activities
  4-80. The corps G-3 contains a cyberspace and electromagnetic activities section that coordinates and
  synchronizes cyberspace and electronic warfare operations for effective collaboration across staff elements.
  The cyberspace and electromagnetic activities section is key to the collaboration of cyberspace and electronic
  warfare operations. The section participates in the planning and targeting process and leads the cyberspace
  and electromagnetic activities working group to support the military decision-making process.
  4-81. Corps staffs request augmentation for cyberspace operations, first from the regional cyber center and
  then from the Army Cyber Operations and Integration Center. This support can cover the range of military
  decision-making process activities including planning for and executing DODIN operations, offensive
  cyberspace operations, defensive cyberspace operations, and electronic warfare operations. The regional
  cyber center working with the Army Cyber Operations and Integration Center will both provide support and
  determine any additional units, assets, or agencies that may be required to achieve military decision-making
  process effects.
