  Note. A division can command multinational forces either as a tactical headquarters or as a joint
  force land component. Normally, these forces are under TACON of a division. Depending on the
  size of the multinational force, the division commander reorganizes the staff and command group
  to accept some members from the other nations to assist and ensure understanding of the various
  national caveats and requirements. The division commander may deploy the tactical command
  post to the command post of a large multinational formation to ensure that the multinational force
  has full connectivity with the division main command post. Normally, a division receives a digital
  liaison detachment to support this requirement.
  DIVISION HEADQUARTERS AS JOINT TASK FORCE HEADQUARTERS
  5-16. In limited contingency operations involving peacekeeping operations, humanitarian operations, or
  limited combat, a division headquarters may become the base for a JTF headquarters. A division may
  integrate with a small theater army command post already deployed and use some of its personnel to
  accelerate JTF staff integration. When it becomes a JTF headquarters, a division headquarters organizes and
  operates in accordance with joint doctrine, which requires extensive augmentation from both joint and Army
  forces. The combatant commander provides joint network capabilities, and each Service provides command
  and control detachments. The USAF provides the JTF with a joint air component coordination element. If
  present, Navy forces normally have a supporting relationship with the JTF. A theater sustainment command
  augments the deployed Army force.
  5-17. When a division headquarters becomes a JTF headquarters, it requires an ARFOR. The quickest
  solution is to designate either the division’s tactical command post or rear command post as the ARFOR
  headquarters. The tactical command post or rear command post, with an assistant division commander, co-
  locates with the largest brigade’s command post and exercises OPCON over land forces while the division
  commander and the main command post forms the JTF headquarters. A less desirable option is to task a
  subordinate brigade with the ARFOR responsibilities, because of the augmentation required.
  5-18. When the division serves as a joint task force, it has all the functions of a tactical headquarters, plus
  the additional functions of—
  * Providing the overall mission, purpose, and objectives for military operations.
  * Defining the JOA.
  * Developing and promulgating the rules of engagement and use of force tailored to the situation.
  * Establishing and assisting liaison with U.S. embassies and foreign governments involved in the
  operation.

  LIMITATIONS
  5-19. There are limitations and dependencies that must be considered throughout a division’s employment.
  Those limitations include, but are not limited to division mobility, security concerns, and Reserve Component
  mobilization.
  Mobility and Security
  5-20. The division main command post is not 100-percent mobile; it requires additional transportation to
  displace. It is also not fully transportable by C-130 aircraft and requires numerous C-17 sorties to deploy by
  air. Normally the main command post deploys by a combination of air and sealift; it also requires reception,
  staging, onward movement, and integration to reach full capacity. No command post has an organic security
  force. The division headquarters tasks a subordinate unit to secure command posts as required.
  Reserve Component Mobilization
  5-21. Two critical Reserve Component organizations mobilize to support a division when it deploys. These
  are the main command post operational detachment and the MEB. The main command post operational
