text: Sustainment Operations During Armed Conflict
  The commander also plans to use engineer assets to block any bypassed enemy withdrawal routes by using
  antivehicle mines, demolitions, and obstacles. Heavy engineer breaching demands to support maneuver
  include increased amounts of demolitions, mine-clearing line charges, and special-purpose charges.
  5-327. The commander uses all available sustainment assets to provide essential support to the force pursuing
  the enemy. Sustainment units should plan for an increased demand for fuel and maintenance as the tempo of
  operations increases. Sustainment units should be highly mobile and able to provide endurance and reach
  during the pursuit. Priority for sustainment normally goes to units having the greatest success. Sustainment
  planners need to anticipate success since the depth of the pursuit depends on the capability of sustainment
  assets to support. Sustainment planners supporting the encircling force need to be prepared to provide
  casualty evacuation over possibly unsecured LOCs. The commander may also need aerial resupply or heavily
  guarded convoys to support this force. Security for sustainment convoys and LOCs becomes a major planning
  consideration.
  5-328. Conducting a pursuit is a prudent risk. Once the pursuit begins, the commander maintains contact with
  the enemy and pursues retreating enemy forces without further orders. The commander maintains the pursuit
  as long as the enemy appears disorganized and friendly forces continue to advance. Sustainment capabilities
  will have a tremendous impact on the ability to mount a successful pursuit. Like exploitation, pursuit tests
  the audacity and endurance of those capabilities. Pursuit requires great energy and resolution on the part of
  the attacking force. Extraordinary physical and mental effort is required to sustain the pursuit, transition to
  other operations, and translate tactical success into operational or strategic victory.
  SUSTAINMENT SUPPORT DURING PURSUIT
  5-329. Pursuit requires increased consumption of fuel and ammunition. Equipment failures and increased
  maintenance requirements may also occur during pursuit. Sustainment planners must anticipate these
  requirements and push packages of fuel, ammunition, and repair parts to corps and division forces in the
  pursuit. Sustainment planners must also be prepared to support the direct-pressure force and encircling force
  during the pursuit. Sustainment commanders must advise maneuver commanders of the limit of advance
  where the maneuver commander could outrun supply.
  5-330. The direct-pressure force conducts hasty attacks to maintain enemy contact and its forward
  momentum until the complete destruction of the retreating enemy force. In the pursuit, the direct-pressure
  force usually conducts the main attack until the enemy force has been destroyed or encircled. The direct-
  pressure force consists of armor units and requires increased amounts of fuel and ammunition. An enveloping
  force gets to the enemy’s rear area as swiftly as possible by the most advantageous routes to cut off the
  enemy’s retreat and blocks the enemy’s escape. The encircling force is required to be mobile to cut off the
  enemy’s retreat. The encircling force will require increased amounts of fuel and repair parts.
  OPERATIONAL FRAMEWORK CONSIDERATIONS
  5-331. In the offense, commanders must design attacks that defeat enemy forces across all echelons while
  enabling subordinate disciplined initiative. When designing attacks, commanders divide the task of defeating
  an enemy force and maintain an integrated approach through deep, close, and rear operations including air,
  space, cyberspace, and maritime capabilities across the operational framework. See FM 3-0 for additional
  information on offensive operational framework considerations.
  EXTENDED DEEP AREA
  5-332. The extended deep area is an important part of any formation’s area of interest because it contains
  enemy capabilities that can inflict damage on friendly forces and affect friendly forces’ operational reach and
  endurance. Commanders integrate the effects and activities of SOF and partner irregular forces in extended
  deep areas.
  DEEP OPERATIONS
  5-333. Deep operations focus on parts of an assigned area that are not in direct fire contact with the main
  body of the formation but may be in the future. At division and corps, which have assigned and attached
  long-range fires capabilities, the deep area extends beyond the forward line of troops to a distance that
  corresponds with the ability of Army and joint capabilities to reach. Divisions and corps integrate SOF,
