  JOINT FORCE LAND COMPONENT HEADQUARTERS
  D-7. A joint force land component headquarters is a component of a unified command, subordinate unified
  command, or JTF. It is responsible to the establishing commander for recommending the proper employment
  of assigned, attached, and available land forces; planning and coordinating land operations; or accomplishing
  such operational missions as may be assigned.
  D-8. A JFC establishes a joint force land component headquarters when the scope, complexity, or other
  factors of an operation require capabilities from at least two military departments operating in the land
  domain. Joint force land component headquarters, at the direction of the JFLCC, are responsible for
  establishing command relationships between subordinate land component commanders and for
  accomplishing assigned operational missions.
  D-9. In some limited contingency operations, the JFC may elect to employ Marine Corps and Army forces
  as Service components, instead of creating a functional joint force land component. In that case, the ARFOR
  and Marine Corps forces would exercise OPCON and ADCON over their respective Service forces. This
  arrangement may occur in a forcible entry operation due to the complexity of vertical insertion, or amphibious
  operations and limited time available for joint integration. As soon as the JOA matures with the arrival of
  follow-on forces and headquarters, the JFC may establish a joint force land component headquarters. Figure
  D-2 is an example of a notional joint force land component headquarters.
