  other phases. A joint support relationship is not used when an Army commander task-organizes Army forces
  in a supporting role. When task-organized to support another Army force, Army forces use one of four Army
  support relationships.
  OTHER AUTHORITIES
  B-13. Some authorities exist outside joint command relationships. These authorities include—
  (cid:122) Administrative control.
  (cid:122) Coordinating authority.
  (cid:122) Direct liaison authorized.
  Administrative Control
  B-14. Administrative control is direction or exercise of authority over subordinate or other organizations in
  respect to administration and support (JP 1, Volume 2). This 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.
  Coordinating Authority
  B-15. Coordinating authority is the authority delegated to a commander or individual for coordinating
  specific functions or activities involving forces of two or more military departments, two or more joint force
  components, or two or more forces of the same Service. The commander or individual granted coordinating
  authority can require consultation between the agencies involved, but that person does not have the authority
  to compel agreement. In the event that essential agreement cannot be obtained, the matter shall be referred
  to the appointing authority. Coordinating authority is a consultation relationship, not an authority through
  which command may be exercised. (See JP 1, Volume 2 for more information on coordinating authority.)
  Direct Liaison Authorized
  B-16. 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, Volume 2). Direct liaison authorized is more applicable to planning than operations, and it 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.
  ARMY COMMAND AND SUPPORT RELATIONSHIPS
  B-17. Army command relationships are similar but not identical to joint command authorities and
  relationships. Differences stem from the way Army forces task-organize internally and the need for a system
  of support relationships between Army forces. Another important difference is the requirement for Army
  commanders to handle the administrative support requirements that meet the needs of Soldiers. These
  differences allow for flexible allocation of Army capabilities within various Army echelons.
  ARMY COMMAND RELATIONSHIPS
  B-18. Table B-2 lists the Army command relationships and authorities typically associated with each.
  Command relationships define superior and subordinate relationships between units. The type of command
  relationship often relates to the expected longevity of the relationship between the headquarters involved,
  and it quickly identifies the degrees of operational and administrative control that the gaining and losing
  Army commanders provide. Army command relationships include:
  (cid:122) Organic.
  (cid:122) Assigned.
  (cid:122) Attached.
