  B-37. A division headquarters may serve as a joint force land component headquarters with staff
  augmentation in a limited contingency operation. With extensive joint augmentation, it may serve as a JTF
  for a limited contingency operation. When serving as the ARFOR or joint force land component, a division
  is primarily concerned with the conduct of operational tasks. The theater army provides most of the ADCON
  and Army support to forces deployed in a JOA. Joint manning documents specify other Service augmentation
  according to the role determined by the combatant commander, either as a JTF or as a joint force land
  component headquarters. When serving as a JTF headquarters, the division headquarters organizes and
  operates in accordance with joint doctrine. (See JP 3-33 for doctrine for the JTF. See JP 3-31 for doctrine for
  the joint force land component command.)
  B-38. When it is the joint force land component, an Army division becomes the ARFOR. As the ARFOR,
  the division retains OPCON of all Army forces not subordinated to another component of the JTF. To
  function effectively as both the joint force land component and the ARFOR, the division headquarters
  requires strong coordination with the TSC. This enables the division to oversee logistic and administrative
  support to all Army forces while also providing logistic support to other Services and multinational units.
  Without it, the ARFOR responsibilities for sustainment would degrade the operational focus of the division.
