  2-37. Figure 2-6 shows an example of allocation of forces to an OSC. The
  units allocated from the administrative force structure to form the OSC typi-
  cally come from an army group, army, or corps (or perhaps a military district
  or military region) or from forces directly subordinate to a service headquar-
  ters. There can also be cases where forces from the services have initially
  been allocated to a theater headquarters and are subsequently re-allocated
  down to the OSC. The organizations shown under the OSC, like those shown
  under the theater headquarters in this example, indicate a pool of assets
  made available to that command. The commander receiving these assets may
  choose to retain them at his own level of command, or he may choose to sub-
  allocate them down to one or more of his subordinates for their use in their
  own task organization.

  Figure 2-6. Allocation of Forces to an OSC (Example)
  2-38. When the NCA decides to execute a particular SCP, each OSC partici-
  pating in that plan receives appropriate units from the OPFOR’s administra-
  tive force structure, as well as interagency and/or multinational forces.
  Forces subordinated to an OSC may continue to depend on the administra-
  tive force structure for support.
