  PREPARING FOR THE DEFENSE
  4-67. In the preparation phase, the OPFOR focuses on ways of applying all
  available resources and the full range of actions to conduct defensive operations.
  Commanders organize their forces and the battlefield with an eye toward
  capitalizing on conditions created by successful defensive actions, and seizing
  opportunities for offensive actions wherever possible. The defensive dispositions
  are based on the application of the systems warfare approach to combat, as
  described in Chapter 1. OPFOR defensive operations focus on attacking
  components or subsystems to of the enemy’s combat system to disaggregate
  the “system of systems.” By denying the enemy the synergy created by an
  integrated, aggregated system, vulnerabilities are created that defensive
  forces can exploit.
  DENY ENEMY INFORMATION
  4-68. Operational-level commanders realize that enemy operations hinge on
  an appreciation of the situation. So, defensive preparations focus on de-
  struction and deception of enemy national and theater sensors. Lethal and
  nonlethal attack of enemy intelligence satellites and reconnaissance aircraft
  can limit the ability of enemy forces to understand the OPFOR defensive
  plan. The OPFOR recognizes that, when conducting operations against an
  extraregional power, it will often be impossible to destroy the ability of the
  enemy’s standoff RISTA means to observe its defensive preparations.
  However, the OPFOR also recognizes the reluctance of enemy military
  commanders to operate without human confirmation of intelligence, as well
  as the relative ease with which imagery and signals sensors may be deceived.
  The OPFOR operational-level commander considers ground reconnaissance
  by enemy special operations Forces as a significant threat in the enemy
  RISTA suite and focuses significant effort to ensure its removal. While the
  OPFOR will execute missions to destroy standoff RISTA means, C3D would
  be the method of choice for degrading the capability of such systems.
  MAKE THOROUGH COUNTERMOBILITY AND SURVIVABILITY PREPARATIONS
  4-69. The more time available, the greater the preparation of an AOR for
  the defense. This is a reflection of engineer effort and time to devote to
  that effort. The OPFOR employs every method to maximize the time
  available to prepare for the defense. This includes preparation of the State
  during peacetime and highly detailed plans for transition from regional to
  adaptive operations to take full advantage of any operational lull as the
  enemy builds combat power. This might involve an offensive operation
  with limited objectives that transitions to the defense by design.
  4-70. Operational-level commanders realize that engineer works are vital to
  the stability of the defense. Engineer assets will be used to improve the ad-
  vantages of complex terrain in protecting friendly forces and exposing enemy
  forces to engagement. Engineer efforts can contribute to creating windows of
  opportunity by degrading the ability of the enemy’s combat system to inte-
  grate the effects of its subsystems.
