  A-13. Forces, not command relationships, are transferred between commands. When forces are transferred,
  the command relationship the gaining commander will exercise (and the losing commander will relinquish)
  over those forces must be specified. When transfer of forces to a joint force will be permanent (or for an
  unknown or extended period) the forces should be reassigned. Combatant commanders will exercise
  COCOM, and subordinate JFCs will exercise OPCON, over reassigned forces. When transfer of forces to a
  joint force will be temporary, the forces are attached to the gaining command, and JFCs, normally through
  the Service component commander, will exercise OPCON over the attached forces. Establishing authorities
  for subordinate unified commands and JTFs direct the assignment or attachment of their forces to those
  subordinate commands as appropriate. When the JFC establishes a command relationship of an Army force,
  the ASCC clearly specifies ADCON responsibilities for all affected Army commanders.
  OTHER AUTHORITIES
  A-14. Other authorities outside joint command relationships include—
  * ADCON.
  * Coordinating authority.
  * Direct liaison authorized.
  These authorities are described in paragraphs A-15 through A-18.
  ADMINISTRATIVE CONTROL
  A-15. Administrative control 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 of the subordinate or other
  organizations. ADCON is a Service authority, not a joint authority. ADCON is exercised under the authority
  of and is delegated by the Secretary of the Army. ADCON is synonymous with the Army’s 10 USC
  authorities and responsibilities. (See AR 10-87 for more information on ADCON.)
  A-16. ADCON does not necessarily follow the operational chain of command at echelons above brigade.
  Unless modified by the Secretary of the Army, administrative responsibilities normally flow from
  Department of the Army through the ASCC to those Army forces assigned or attached to that combatant
  command. As the ASCC, the theater army delegates ADCON as required to Army forces assigned or attached
  by the combatant commander to a joint (or joint and multinational) task force. The ARFOR commander and
  associated headquarters exercise ADCON of Army forces within that JTF specified by the theater army
  commander. (See Appendix B for a discussion of echelon above brigade ADCON responsibilities.)
  COORDINATING AUTHORITY
  A-17. The coordinating authority is a commander or individual who has the authority to require consultation
  between the specific functions or activities involving forces of two or more Services, joint force components,
  or forces of the same Service or agencies, but does not have the authority to compel agreement (JP 1).
  Commanders or individuals may exercise coordinating authority at any echelon at or below the level of
  combatant command. The common task to be coordinated will be specified in the establishing directive
  without disturbing the normal organizational relationships in other matters. Coordinating authority is a
  consultation relationship, not an authority through which command may be exercised. Coordinating authority
  is more applicable to planning and similar activities than to operations. For example, a division commander
  may delegate coordinating authority to an assistant division commander for operations in the rear area.
  DIRECT LIAISON AUTHORIZED
  A-18. Direct liaison authorized is that authority granted by a commander (any level) to a subordinate to
  directly consult or coordinate an action with a command or agency within or outside of the granting command
  (JP 1). Direct liaison authorized is more applicable to planning than operations and always carries with it the
  requirement of keeping the commander granting direct liaison authorized informed. Direct liaison authorized
  is a coordination relationship, not an authority through which command may be exercised.
