  subordinate units are likely to be occupying defensive battle positions. (See
  Chapter 4 for further discussion of simple and complex battle positions.)
  2-75. Disruption Zone. The disruption zone is where the OPFOR sets the
  conditions for successful operations by beginning the attack on the compo-
  nents of the enemy combat system. A successful disruption zone operation
  can create a window of opportunity that is exploitable in the battle zone. In
  the disruption zone, the OPFOR attacks specific components of the enemy’s
  combat system in order to begin the breakdown of the system. For example,
  attack of all enemy engineer forces can leave a maneuver force unable to con-
  tinue effective combat operations in complex terrainexposing them to de-
  struction by forces in the battle zone. Actions of forces in the disruption zone
  are detailed in Chapters 3 and 4. Disruption zones may be contiguous or non-
  contiguous with other disruption zones, or they may be “layered.”
  2-76. Battle Zone. The battle zone is the portion of the AOR where the
  OPFOR expects to conduct decisive operations. Using all components of its
  combat power, the OPFOR will engage the enemy and defeat him in this
  zone. Units operating in the battle zone can have various missions and objec-
  tives, depending on the nature of the overall offensive or defensive operation
  (see Chapters 3 and 4).
  2-77. An FG or OSC does not form an operational-level battle zone per
  sethat zone is the aggregate of the battle zones of its subordinate units. In
  a nonlinear operation, multiple, noncontiguous battle zones may exist, and
  within each a certain task would be assigned to the OPFOR unit or units
  charged to operate in that space. The battle zone provides the commander of
  each of those units the battlespace in which to frame his operations.
  2-78. Support Zone. The support zone is that area of the battlespace de-
  signed to be free of significant enemy action and to permit the effective logis-
  tics and administrative support of forces. Security forces operate in the sup-
  port zone in a combat role to defeat enemy special operations forces and other
  threats. Camouflage, concealment, cover, and deception (C3D) measures oc-
  cur throughout the support zone to protect the force from standoff RISTA and
  precision attack. The OSC support zone may be dispersed within the support
  zones of subordinate tactical units, or the OSC may have its own support
  zone that is separate from subordinate AORs. The support zone may be in a
  sanctuary that is noncontiguous with other zones of the AOR.
  2-79. Attack Zone. An attack zone is given to a subordinate unit with an of-
  fensive mission, to delineate clearly where forces will be conducting offensive
  maneuver. Attack zones are often used to control offensive action by a subor-
  dinate unit inside a larger defensive operation.
  2-80. Kill Zone. A kill zone is a designated area on the battlefield where the
  OPFOR plans to destroy a key enemy target, usually by fires. A kill zone may
  be within the disruption zone or the battle zone. In defensive operations, it
  could also be in the support zone.
