  3-69. A theater army and its subordinate MIB-T may provide intelligence support to Army and joint forces
  in the joint operations area. The theater military intelligence brigade’s regional focus enhances its capabilities
  to develop and exploit language skills and cultural insights specific to an AOR. The regional focus also
  provides the benefits of continuity and cultural context to its analytic intelligence products. The theater
  military intelligence brigade can collect, analyze, and track the threat characteristics and doctrine of partner
  nations, enemies, and adversaries over many years, providing indications and warnings of changes in an OE.
  These abilities allow the brigade to create and maintain a valuable database of intelligence regarding regional
  military forces, persons of interest, and evolving doctrine and capabilities of regional military forces. (See
  FM 2-0 for more information on the MIB-T.)
  Theater Fires Command/Element
  3-70. An Army theater fires command and a theater fires element provides command and control of assigned
  strategic fires capabilities, serves as the senior headquarters assigned to an ASCC/theater army to integrate
  theater fires assets, and executes critical fire support functions across the competition continuum. The
  organizational difference is minimal. The two different organizational structures represent requirements in
  different regions and may continue to evolve.
  3-71. The theater fires command and theater fires element are designed to develop, nominate, and converge
  effects on joint targets across the theater. This support to joint targeting will support the continuous setting
  of the theater to enable joint force land component command, field army, and corps operations during
  competition below armed conflict and crisis. The theater fires command ensures the Army's contribution to
  the joint targeting process is effectively planned and executed during shape and prevent and can seamlessly
  transition to large-scale ground combat operations in accordance with the ground force commander's
  priorities. This also provides greater deterrence options for the theater. (See FM 3-09 for additional
  information on theater fires commands/elements.)
  Civil Affairs Command
  3-72. The civil affairs command is the theater army civil affairs capability. Each theater army (except for
  U.S. Army North) receives support from a civil affairs command. The civil affairs command provides
  theater-level civil affairs planning, coordination, policies, and programs to support the geographic combatant
  command’s regional civil-military operations strategy and stabilization, reconstruction, and development
  efforts. The civil affairs command mobilizes and deploys with one or more civil affairs brigades and civil
  affairs planning teams. It also has one or more civil-military operations centers.
  3-73. One civil affairs brigade normally supports the land component command; a second brigade may
  support the ESC. A civil affairs brigade with its civil-military operations center can become the core of a
  joint civil-military operations task force under the OPCON of the JTF. Civil affairs battalions from the civil
  affairs brigade are task-organized to Army divisions. Civil affairs planning teams augment the geographic
  combatant command, theater army, joint land forces component command, and division, corps, and brigades.
  Such augmentation provides liaison, coordination, education and training, and area assessment functions.
  (See FM 3-57 for more information on civil affairs brigades.)
  THEATER-LEVEL ARMY FORCES FOR THE EXPANDED THEATER
  3-74. Campaigns that include large-scale combat operations cause the theater army to expand to support
  Army, joint, and multinational forces. This occurs as the combatant commander adapts the joint command
  and control mechanism to the demands of the campaign. The theater army maintains its AOR-wide focus
  while developing a mature support structure within the joint operations area. The mature theater could include
  some or all of the commands listed in paragraphs 3-70 through 3-82. (See figure 3-3 for a depiction of the
  expanded theater.)
