  Figure 1-2. Example of corps as an intermediate land force headquarters
  1-19. When designated as a joint force land component, the corps exercises command over Marine Corps
  forces as required by the joint force commander. The corps functions as an operational-level headquarters. If
  the joint force commander elects to establish a joint security area (JSA) within the joint operations area, the
  joint force commander normally determines its structure and controlling headquarters. The options for the
  JSA depend on the threat and mission variables, particularly forces available. If the threat to the JSA is low
  to moderate, the theater army commander may tailor ARFOR with a MEB specifically for controlling the
  JSA. The MEB may include additional military police and intelligence assets. If the threat to theater bases
  and lines of communications is significant, the theater army may tailor ARFOR with an additional BCT to
  control that AO. A third option, in the case of very high threat levels, is to assign the mission to an Army
  division with BCTs.
  1-20. When assigned the mission of supporting echelons above division, joint, or multinational forces, the
  MEB could be task-organized with other Service or national units and integrated staff augmentation to
  provide command and control for a variety of elements necessary to support those forces. The MEB may be
  assigned its own AO in such a role. When assigned to a joint command, the MEB may provide command
  and control of the JSA. In this case, the MEB commander may be designated as the joint security coordinator
  by a joint force commander. The MEB may be required to establish or support a theater level joint security
  coordination center. (See JP 3-10 for additional information on a MEB serving as a joint security coordination
  center for a JSA.) The MEB can also support functional component commands, a joint force, or another
  Service.
  Other Brigade Support
  1-21. The MEB could be tasked to provide support to other divisional units, to include BCTs, functional
  brigades, or other support brigades. The division may task the MEB to conduct certain operations in general
  support to the division with selected tasks that require direct support to the main effort, such as protecting
  critical capabilities, assets, and activities. When providing general support, other brigades in the division
  coordinate their requirements with the division staff and the MEB. Based on the division commander’s intent,
