  cases, an OSC disruption zone may extend beyond those of its subordinates,
  to include an area occupied by forces sent out under direct control of the
  OSC. OSC-level forces could include SPF and affiliated forces, which could be
  operating in enemy-held territory even before the beginning of hostilities.
  There could also be stay-behind forces in areas seized by the enemy. A field
  group (FG) or theater commander controlling multiple OSCs can have a disrup-
  tion zone and may assign an OSC to operate in that zone.
  3-33. In the offense, the disruption zone exists to
  • Disrupt defensive works and preparations.
  • Delay or fix enemy counterattacks or response forces.
  • Attack lucrative targets (key systems or vulnerable troops).
  3-34. Disruption forces often maneuver to fix enemy forces and place long-
  range fire on key enemy units. They can also strip away the enemy’s recon-
  naissance assets (to deceive him of the location and configuration of the at-
  tack) while denying him the ability to acquire and engage the OPFOR with
  deep fires. This includes an air defense effort to deny aerial attack and re-
  connaissance platforms from targeting forces in the zone. A disruption force
  seeks to conduct highly damaging local attacks. It ensures that a covered
  withdrawal route exists to avoid decisive engagement.
  3-35. Typical systems, units, or facilities to be attacked by a disruption force
  are
  • C2 systems.
  • RISTA assets.
  • Aviation assets.
  • Precision fire systems.
  • Logistics support areas.
  • LOCs.
  • Mobility and countermobility assets.
  • Casualty evacuation routes and means.
  3-36. The disruption zone is bounded by the battle line and the LOR of the
  overall AOR. In linear offensive operations, the higher headquarters may
  move this LOR forward as the force continues successful offensive operations.
  Thus, the boundaries of the disruption zone will also move forward during
  the course of an operation. The higher commander can push the disruption
  zone forward or outward as forces adopt a defensive posture while consolidat-
  ing gains at the end of a successful offensive operation and/or prepare for a
  subsequent offensive operation.
  Battle Zone
  3-37. In the offense, the battle zone is that battlespace in which the OPFOR
  seeks to fix and/or destroy enemy forces through simultaneous or sequential
  application of all components of combat power. The dimensions of this zone
  are based on OPFOR objectives and the time-space relationships for the
  forces involved.
