  PROVIDE ADMINISTRATIVE CONTROL OF ARMY FORCES
  3-28. ADCON is not a command relationship. ADCON is direction or exercise of authority over subordinate
  or other organizations in respect to administration and support. The exercise of ADCON fulfills a military
  department’s statutory responsibilities. ADCON is synonymous with administration and support
  responsibilities identified in 10 USC. The Secretary of the Army’s United States Code responsibilities are
  exercised through ADCON. ADCON includes organization of Service forces, control of resources and
  equipment, personnel management, unit logistics, individual and unit training, readiness, mobilization,
  demobilization, discipline, and other matters not included in the operational missions. The theater army
  headquarters is responsible for ADCON of all Army forces in the AOR in peacetime and wartime. (See AR
  10-87 for more information on ADCON.)
  3-29. The Secretary of the Army exercises ADCON through theater army commanders assigned to the
  combatant commands, unless otherwise specified by the Secretary of Defense. ADCON normally extends
  from the Secretary of the Army through the ASCC, to Army units assigned to the ASCC; or through the
  ASCC and an ARFOR to Army units assigned or attached to an Army headquarters in a joint command
  subordinate to a CCMD. ADCON is not tied to the operational chain of command. The Secretary of the Army
  may redirect some or all Service responsibilities outside the normal ASCC channels. In similar fashion, the
  ASCC may distribute some administrative responsibilities outside the ARFOR. The primary considerations
  are the effectiveness of Army forces and the care of Soldiers (administration, support, and force protection).
  3-30. The theater army commander answers to the Secretary of the Army for the administration, support,
  and force protection of all Army forces assigned or attached to the combatant command, or transiting through
  the AOR. This is the authority necessary to fulfill Military Department statutory responsibilities for
  administration and support.
  3-31. The theater army commander remains responsible to the Department of the Army for Service-specific
  requirements. This falls under the ADCON chain of authority. This authority establishes a hierarchy for Army
  support to deployed forces without modifying the operational chain of command that runs from the combatant
  commander through subordinate JFCs. For example, theater army commanders establish centers in the AOR
  to train individual replacements; complete collective training, theater orientation, and theater acclimation;
  and manage force modernization of Army forces before their employment by the JFC in the JOA. (See
  ADP 3-0 for more information on Service-specific requirements.)
  SET AND MAINTAIN THE THEATER
  3-32. The term set the theater refers to a broad range of actions necessary to employ landpower before and
  during a crisis. Setting the theater includes a whole-of-government initiatives, including bilateral or
  multilateral diplomatic agreements that allow U.S. forces access to ports, terminals, airfields, and bases in
  the AOR to support future military contingency operations. Setting the theater is a continuous shaping activity
  and is conducted a part of steady-state posture and for contingency or crisis response operations. This includes
  base development; theater opening; reception, staging, onward movement, and integration; and other
  operational activities which set the conditions for operations in the AOR. The theater army, in conjunction
  with its associated theater fires command, prepares fires estimates, and participates in the joint targeting
  process to set conditions for future operations. The theater army, in conjunction with its associated TSC,
  prepares sustainment estimates that outline the responsibilities and requirements for setting the theater where
  U.S. military presence is forward stationed or deployed. The theater army executes many of these
  responsibilities through the TSC. (See ATP 3-93 for more information on setting the theater.)
  SET AND SUPPORT OPERATIONAL AREAS
  3-33. In addition to setting and maintaining the overall theater, theater armies play an important part in
  setting and supporting specific operational areas for JFCs. They orchestrate and synchronize Army activities
  that create conditions of advantage for the joint and multinational force. While setting and maintaining the
  theater are inherently strategic, actions to set and support operational areas focus on the operational and
  tactical levels of warfare. Examples of key tasks that theater armies may perform to support this include
  reception, staging, onward movement, and integration; force tailoring; force protection; and provide
