  TACTICAL CONTROL
  B-5. Tactical control is the authority over forces that is limited to the detailed direction and control of
  movements or maneuvers within the operational area necessary to accomplish missions or tasks assigned (JP
  1). Tactical control is inherent in OPCON. It may be delegated to and exercised by commanders at any
  echelon at or below the level of combatant command. Tactical control provides sufficient authority for
  controlling and directing the application of force or tactical use of combat support assets within the assigned
  mission or task. Tactical control does not provide organizational authority or authoritative direction for
  administrative and logistic support; the commander of the parent unit continues to exercise these authorities
  unless otherwise specified in the establishing directive.
  SUPPORT
  B-6. Support is the action of a force that aids, protects, complements, or sustains another force in accordance
  with a directive requiring such action (JP 1). Support is a command authority in joint doctrine. A supported
  and supporting relationship is established by a superior commander between subordinate commanders when
  one organization should aid, protect, complement, or sustain another force. Designating supporting
  relationships is important. It conveys priorities to commanders and staffs planning or executing joint
  operations. Designating a support relationship does not provide authority to organize and employ commands
  and forces, nor does it include authoritative direction for administrative and logistic support. Joint doctrine
  divides support into the categories listed in Table B-1 (page B-3).
  ARMY COMMAND AND SUPPORT RELATIONSHIPS
  B-7. As discussed in Chapter 2, Army command relationships include:
  * Organic.
  * Assigned.
  * Attached.
  * OPCON.
  * TACON.
  B-8. See Table B-1 (on page B-3) for an illustration of Army command relationships.
  ORGANIC
  B-9. Organic forces are those assigned to and forming an essential part of a military organization as listed
  in its table of organization for the Army, Air Force, and Marine Corps, and are assigned to the operating
  forces for the Navy (JP 1). Joint command relationships do not include organic because a JFC is not
  responsible for the organizational structure of units. That is a Service responsibility.
  B-10. The Army establishes organic command relationships through organizational documents such as tables
  of organization and equipment and tables of distribution and allowances. If temporarily task-organized with
  another headquarters, organic units return to the control of their organic headquarters after completing the
  mission. To illustrate, within a BCT, all subordinate battalions are included on the BCT table of organization
  and equipment. In contrast, within most functional and multifunctional brigades, there is a base of organic
  battalions and companies and a variable mix of assigned and attached battalions and companies.
  ASSIGNED
  B-11. Assign is to place units or personnel in an organization where such placement is relatively permanent,
  and/or where such organization controls and administers the units or personnel for the primary function, or
  greater portion of the functions, of the unit or personnel (JP 3-0). Unless specifically stated, this relationship
  includes administrative control (ADCON).
