  and execution must address flexibility through operations in depth and support to defensive maneuver.
  Additional fire support considerations for supporting the commander’s concept of operations include—
  (cid:122) Weight the main effort.
  (cid:122) Provide 360-degree air and missile defense coverage.
  (cid:122) Provide and disseminate early warning.
  (cid:122) Contribute targeting information.
  (cid:122) Engage critical enemy assets with fires before the attack.
  (cid:122) Plan counterfire against enemy indirect-fire systems attacking critical friendly elements.
  (cid:122) Use lethal and nonlethal means to apply constant pressure to the enemy’s command and control
  structure.
  (cid:122) Provide fires to support defensive counterair operations to defeat enemy attacks.
  (cid:122) Plan the acquisition and attack of HPTsthroughout the area of operations.
  (cid:122) Employ electromagneticattack to degrade,neutralize,or destroy enemy combat capability.
  (cid:122) Concentrate fires to support decisive action.
  (cid:122) Provide fires to support counterattacks.
  (cid:122) Plan fires to support the barrier and obstacle plan.
  (cid:122) Planfor target acquisition and sensors to provide coverage of NAIs,TAIs,and critical assets.
  (cid:122) Plan for friendly force and allied force fratricide prevention measures.
  (cid:122) Plan for civilian noncombatant casualty prevention measures.
  (cid:122) Plan for un-intended collateral damage prevention measures.
  (cid:122) Request munitions authorities to ensure appropriate units on the ground have the operational and
  legal authority to employ munitions such as scatterable mine systems (air and ground volcanos).
  7-64. The BCT may utilize unmanned aircraft systems (UASs), remote sensors, and reconnaissance and
  security forces to call for fire on the enemy throughout the area of operations. Quick, violent, and
  simultaneous action throughout the depth of the defender’s area of operations can degrade, confuse, and
  paralyze an enemy force just as that enemy force is most exposed and vulnerable. (See FM 3-09 and
  FM3-90-1 for additional information.)
  SUSTAINMENT
  7-65. Typically, sustaining operations in support of the defense requires more centralized control. Clear
  priorities of support, transportation, and maintenance are required. The BCT closely and continuously
  coordinates, controls, and monitors the movement of materiel and personnel within the operational
  environment based on the BCT’s priorities and ensures their dissemination and enforcement. (See FM4-0
  for additional information.)
  7-66. The routing function of movement control becomes an essential process for coordinating and directing
  movements on main supply routes or alternate supply routes and regulating movement on lines of
  communications to prevent conflict and congestion. Movement priorities must include throughput of
  echelons above brigade assets transporting additional engineer assets in preparation for the defense. Supply
  ofclass IV (construction and barrier materials) and class V (ammunition) normally have higher movement
  priorities during the defense. Planners may consider nighttime resupply operations to minimize enemy
  interference. (SeeATP 4-16 for additional information.)
  7-67. TheBCT logistics staff officer (S-4) must ensure that the sustainment plan is coordinated fully with
  the rest of the staff. The S-4 coordinates with the brigade operations staff officer (S-3) to ensure that supply
  routes do not interfere with maneuver or obstacle plans but still support the full depth of the defense.
  Sustainment planners must consider prepositioning class IV,class V,and class III (bulk) far forward initially
  to support the security area during the counterreconnaissance fight,followed by the MBA so that the BCT
  can rapidly transition from defense to offense. Planning for sustainment operations throughout the security
  area is critical to sustaining reconnaissance and security operations to prevent enemy forces from determining
  friendly force disposition. Forces within the security area are configured prior to line of departure with a
  minimum of 72 hour logistics package (LOGPAC) of class I (subsistence), class III (petroleum, oils, and
