  on the mission of the OSC. In some cases, the OPFOR may include a limited
  number of army aviation assets in the formation of a DTG or BTG.
  COMMAND AND CONTROL
  8-13. The commander of the theater air army (Air Force asset) is subordinate
  to the theater commander. If the majority of the air army’s assets retained at
  theater level are allocated to the theater IFC, the air army commander may
  also become subordinate to the IFC commander. The air army command post
  (CP) is normally within 10 to 15 km of the theater’s main CP or IFC CP to
  ensure a close relationship. This relationship ensures that there is no danger
  of the air army conducting separate, divergent operations as opposed to sub-
  ordinating the air effort to the needs of the ground operation.
  8-14. The senior commander of the army aviation component is also directly
  subordinate to the theater commander or the theater IFC commander. The
  army aviation CP is located within 30 km of the theater main CP or IFC CP
  to allow for rapid coordination from theater to the executing unit. The staff of
  the aviation unit works closely with the theater staff to plan and coordinate
  the employment of the theater’s army aviation assets.
  8-15. The command structure at the OSC level is similar to that at theater
  level. The OSC may have an air army, division, or regiment as the largest Air
  Force organization. Depending on the type of aviation assets involved, the
  commander of this unit is subordinate to the OSC commander or to the OSC
  IFC commander.
  8-16. The command structure for army aviation units in an OSC depends on
  the types of aviation units assigned and whether or not they perform or support
  fire support missions. Thus, the commander of the army aviation unit may be di-
  rectly subordinate to the commander of the OSC or to the OSC IFC commander.
  CENTRALIZED CONTROL
  8-17. The OPFOR has a limited number of aviation units compared to the
  size of the ground force. For this reason, it believes that maintaining centralized
  control over its aviation assets is essential to the effective employment of both
  fixed-wing and rotary-wing aircraft. However, centralization is a relative term,
  depending on what levels of command are involved.
  Fixed-Wing
  8-18. The OPFOR establishes relatively centralized control over its fixed-
  wing assets. Centralization takes advantage of the mobility and maneuver-
  ability of aircraft to concentrate them at the decisive point and time from
  dispersed bases. Centralized control simplifies the coordination with ground
  forces and allows for the integration of aircraft being used in different, but
  complimentary roles (for example, reconnaissance, fighter, and ground attack). It
  also allows a rapid reallocation of air support resources to accomplish the
  more important missions that suddenly arise during an operation. Aviation
  units not originally assigned for ground support may sometimes take part in
  delivering air attacks against ground targets. To execute their missions, the
  OPFOR uses centralized planning to allocate air support resources to the ground
  commander by flights or aircraft sorties with the appropriate ammunitions.
