  2-34. The General Staff does not normally form standing FG headquarters,
  but may organize one or more during full mobilization, if necessary. An FG
  can be assigned responsibilities in controlling forces in the field during adap-
  tive operations in the homeland, or forward-focused functionally (an FG may
  be assigned an access-control mission). However, FGs may exist merely to ac-
  commodate the number of forces in the theater.
  2-35. FGs are typically formed for one or more of the following reasons:
  • An SCP may require a large number of OSCs and/or operational-level
  commands from the administrative force structure. When the number
  of major military efforts in a theater exceeds the theater commander’s
  desired or achievable span of control, he may form one or more FGs.
  (See Figure 2-4.)
  • In the rare cases when multiple operational-level commands from the
  administrative force structure become fighting commands, they could
  come under the command of an FG headquarters. (See Figure 2-5.)
