  9-151. Air defense units relocate as necessary to provide continuous and ef-
  fective protection to the supported unit. OPFOR commanders maintain effective
  protection by leaving at least one air defense battery in firing position to cover
  the movement. Air defense units constituent to or augmenting a maneuver unit
  usually move as a part of that unit if the air threat is high. If there is little or no
  air threat, these air defense assets may move separately to a new location.
  DEFENSE
  9-152. Air defense units seek to provide coverage to all levels of the organiza-
  tion. They must integrate this coverage with the ground operation and ensure
  continuous air defense. Air defense must provide all-around security because
  air attack can come from any direction. The OPFOR must coordinate fires
  among all air defense units and supported maneuver units. This provides an
  integrated air defense.
  9-153. Under conditions when the OPFOR can employ integrated defense, it
  generally can also employ integrated air defense, integrated both vertically
  and horizontally. During transition and adaptive operations, however, decen-
  tralized conditions may affect the ability to integrate horizontally and thus
  provide mutual support. The same would apply to the commander’s ability to
  achieve vertical integration between the tactical and operational levels.
  DEPLOYMENT
  9-154. Deployments closely parallel those in the offense, but there are some
  differences. The positioning of operational-level air defense assets depends on
  the overall organization of the battlefield for the defense. Operational-level
  SAM units might deploy to provide point protection for the main CP, SSM
  units, airfields, or other high-value assets. The SAMs might cover units in
  sanctuary areas or sanctuaries into which maneuver units may deploy. They
  might cover lines of commitment for an operational-level counterattack. The
  OPFOR sees the threats posed by air reconnaissance and airborne or heli-
  borne assault as being greater in the defense and devotes greater effort to
  guarding against those threats.
  Disruption Zone
  9-155. Air defense in the disruption zone should provide area coverage to de-
  fend forces in the zone and provide point protection for key assets involved in
  conducting fires. Even the systems providing point protection must be highly
  mobile and capable of moving with units as they displace to hides or new fir-
  ing positions or conduct survivability moves.
  9-156. Forces operating in the disruption zone are typically separated from
  sanctuary areas in both time and space. This separation typically requires
  the OSC commander to place air defense units in the disruption zone to sup-
  port the disruption mission. Such deployment allows the OPFOR to detect,
  track, and attack air platforms in the disruption zone and beyond. This can
  involve deployment of divisional or even OSC air defense assets (radars as
  well as weapon systems) well into the disruption zone. These forces occupy pre-
  pared and camouflaged positions to support other units in the disruption zone.
  As in the offense, they try to prevent enemy aerial reconnaissance platforms
