  friendly battle positions and denying the ability of subsequent echelons to support the lead echelon.
  Commanders use rocket artillery, rotary-wing aviation, UASs, special operations forces, space and
  cyberspace capabilities, electromagnetic warfare, and influence activities to conduct deep operations.
  Commanders request joint fires to divert, disrupt, delay, or destroy the enemy’s long-range capabilities before
  they are in direct contact with Army forces. The battlefield coordination detachment, as the senior Army
  operational commander’s liaison with the air component, serves a central role in relaying requests for joint
  fires to the joint air operations center. (See JP 3-03 for information on interdiction.)
  6-195. Deep operations begin to disrupt the cohesion of the enemy attack as early as possible, before the
  enemy closes with maneuver forces in the security area. Psychological effects degrade the will of enemy
  forces to fight, interfere with enemy decision making, and disrupt enemy attacks as they begin, especially
  when combined with attacking C2 nodes, fires, and other key capabilities. Deception to conceal the location
  and disposition of defending forces and limit the effectiveness of enemy fires delays the enemy’s ability to
  mass effects. Army forces in the defense conduct deep operations to—
  (cid:122) Isolate enemy forces in the security area and main battle area from follow-on echelons.
  (cid:122) Disrupt the enemy’s ability to support committed forces with fires and logistics.
  (cid:122) Guard against interference with the commitment of friendly reserves.
  (cid:122) Attrit sufficient enemy combat power to achieve favorable force ratios in the main battle area.
  (cid:122) Transition to the offense.
  6-196. As part of conducting deep operations, corps and division commanders maintain a current
  intelligence picture of enemy forces throughout their area of interest. They coordinate for and integrate effects
  created by special operations core activities to achieve operational and strategic objectives and disrupt enemy
  forces, capabilities, and infrastructure that support enemy offensive operations. Commanders also ensure that
  deep operations remain focused on setting conditions for forces in the security and main battle areas while
  avoiding becoming overly fixated on close operations.
  6-197. As enemy formations approach the forward line of troops, leaders monitor enemy movements,
  determine which elements of the enemy force are most threatening, and attack high-payoff targets, including
  enemy long-range fires, air defense systems, logistics assets, and C2 nodes. The commander uses
  reconnaissance and security forces and fires to disrupt the enemy approach and delay enemy second echelon
  forces and reserves in ways that desynchronize the enemy attack. When available, commanders employ
  offensive space and cyberspace capabilities in combination with electromagnetic attacks to disrupt enemy
  communications and hinder the enemy’s ability to adapt. Deep operations in the defense may also seek to
  suppress enemy air defenses to enable friendly air capabilities, including air interdiction and close air support,
  to operate in the security area and main battle area.
  6-198. Commanders synchronize deep operations among subordinate echelons through the use of fire
  support coordination measures. Coordinated fire lines are permissive fire support coordination measures that
  commanders can use for rapid engagement of targets while simultaneously providing flexibility for friendly
  forces. In the defense, the corps establishes a coordinated fire line with subordinate divisions, so that the
  corps can target critical enemy capabilities with surface-to-surface fires beyond where the divisions need to
  focus in their own close and deep areas.
  SECURITY AREA OPERATIONS
  6-199. During the defense, the security force occupies an assigned area far enough forward of the forward
  edge of the battle area to protect main battle area units from surprise. Security forces provide early warning
  to give main battle area units time to reposition forces against enemy maneuver and to mitigate the effects of
  enemy medium-range fires.
  6-200. Commanders have the option of employing a screen, guard, or cover in a security area, depending
  on the mission variables. When deciding which option to use, commanders consider the following:
  (cid:122) The depth, breadth, and terrain of the security area relative to number of forces available.
  (cid:122) The capabilities of the security force relative to the threat it faces, particularly its mobility.
  (cid:122) The amount of time the commander needs the security force to provide forces in the main battle
  area.
