  2-39. If a particular OSC has contingency plans for participating in more
  than one SCP, it could receive a different set of forces under each plan. In
  each case, the forces would be task organized according to the mission re-
  quirements in the given plan. Thus, each OSC consists of those division-,
  brigade-, and battalion-size organizations allocated to it by the SCP currently
  in effect. These forces also may be allocated to the OSC for the purpose of
  training for a particular SCP. When an OSC is neither executing tasks as
  part of an SCP nor conducting exercises with its identified subordinate
  forces, it exists as a planning headquarters.

  2-40. Figure 2-7 shows an example of the types of organizations that could
  make up a particular OSC organization. The numbers of each type of
  subordinate and whether they actually occur in a particular OSC can vary.
  As shown in this example, the composition of an OSC is typically joint,
  with Air Force and possibly maritime (naval or naval infantry) units,
  and it can also be interagency. If some of the allocated forces come
  from another, allied country, the OSC could be multinational. The
  simplified example of an OSC shown here does not show all the combat
  support and combat service support units that would be present in such an
  organization. Many of these support units are found in the integrated fires
  command (outlined below) and the integrated support command (outlined
  below and in Chapter 12). Other support units could be allocated initially
  from the administrative force structure to the OSC, which further allocates
  them to its tactical subordinates.
