  4-47. A typical complex battle position contains
  • Complex terrain.
  • A substantial logistics cache.
  • Extensive engineer fortification and obstacle work.
  • C3D effort to confuse the enemy picture of strength and disposition.
  • Precision fire capability.
  • Mobile reserves.
  • Air defense systems.
  • Redundant C2 systems.
  ORGANIZING FORCES FOR THE DEFENSE
  4-48. In his operation plan, the operational-level commander also specifies
  the organization of the forces within his level of command. Thus, subordinate
  forces understand their roles within the overall operation. However, the or-
  ganization of forces can shift dramatically during the course of an operation.
  For example, a unit that initially was part of a disruption force may eventu-
  ally occupy a battle position within the battle zone and become part of the
  main defense force or act as a reserve.
  4-49. Each of the separate functional forces has an identified commander.
  This is often the senior commander of the largest subordinate unit assigned
  to that force. For example, if two DTGs and a separate BTG are acting as the
  OSC’s main defense force, the senior of the two DTG commanders is the main
  defense force commander. During decentralized operations, even when the force
  consists of like units of the same command level, control can be delegated to the
  senior commander of that force’s like units. Since, in this option, each force
  commander is also a subordinate unit commander, he controls the force from
  his unit’s command post (CP).
  4-50. Another option is to have one of the OSC’s or FG’s CPs be in charge
  of a functional force. Particularly during dispersed defensive operations,
  functional forces that contain units of the same command level might be
  controlled from the forward, auxiliary, or airborne CP of the OSC or FG.
  For example, the forward CP could control a disruption force. Another
  possibility would be for the IFC CP to command the disruption force or
  any other force whose actions must be closely coordinated with fires deliv-
  ered by the integrated fires command (IFC).
  4-51. In any case, the force commander is responsible to the OSC or FG
  commander to ensure that combat preparations are made properly and to
  take charge of the force during the operation. This frees the operational-level
  commander from decisions specific to the force’s mission. Even when tactical-
  level subordinates of an OSC or FG have responsibility for parts of the OSC
  or FG disruption zone, there is still an overall OSC or FG disruption force
  commander.
