text: Fire Support in Depth During Large-Scale Combat Operations
  6-131. Assault:
  * As the maneuver force assaults through breach to destroy the enemy, FA and mortars should
  continue suppression fires and be prepared to lift or shift fires as the force approaches the enemy
  battle positions.
  6-132. Key EFSTs in support of a breaching operation include:
  * Mortars - provide suppression and obscuration or screening fires.
  * FA - isolate the breach area and suppress the enemy; provide obscuration/screening fires, and in
  coordination with the S-3, establish/manage radar CFZs.
  * CAS - isolate and suppress the enemy; disrupt the enemy counterattack.
  * Attack helicopters - isolate and suppress the enemy; disrupt the enemy counterattack.
  * Intelligence - locate and identify HPTs among enemy units in the vicinity of the breach area.
  * Electronic attack - identify, locate, and jam the enemy communications associated with units in
  the vicinity of the breach area.
  * Obscuration (projected and generated) - isolate the breach area.
  * Scatterable mines - prevent repositioning of enemy forces without hindering friendly actions on
  the objective; disrupt the enemy counterattack.
  6-133. FSE work closely with the G-2 during IPOE and information collection. Scouts and other observers
  can often provide accurate targeting. The FSCOORD and FSE planners may designate the reduction area (or
  points of breach) and support-by-fire positions providing cover as WLRs CFZs so that they are treated as
  priority targets for counterfire support. The key is getting targeting information into the FS system and
  executing fires at the critical time. Scouts and other observers can also be effective in setting and controlling
  fires for obscuration within the breach area by adjusting fires and correcting for the actual conditions of wind
  speed and direction.
  6-134. In accordance with the scheme of fires, tasks to be executed by FS (to include mortars) in support
  of the breach may include:
  * Provide fires for obscuration and suppression.
  * Destroy or suppress enemy artillery and mortars.
  * Destroy or suppress enemy antitank weapon systems.
  * Destroy or suppress enemy dismounted infantry positions.
  * Delay, disrupt, and neutralize enemy repositioning forces.
  * Destroy, suppress, or obscure enemy observation posts.
  6-135. The commander designates and assigns priority targets to make indirect fires more responsive to the
  supported unit execution. Observers must be employed to effectively engage such targets during a maneuver
  force breaching operation. The FSCOORD, FSE and fire control personnel monitor the command network
  and lift and shift fires at the critical time, should the primary executor be unable to execute.
  6-136. Attack/delivery systems cross the obstacle with the forces they support to extend the breach and
  ensure continuous support of follow-on operations. Positioning is critical at the breach area. FS assets should
  be positioned to support the breaching operation, but not interfere with the approach, the breach, or assault
  forces. Breaching operations consume a significant amount of ammunition. Planners must consider pre-
  positioning stocks of smoke, HE, and precision munitions.
  6-137. In coordination with the G-3, the FSCOORD and FSE consider the requirements for protection at
  the breach area. They also plan for WLRs zones and consider the enemy phases of fire for defensive
  operations. The FSCOORD and FSE consider CFZs and FSCMs between the enemy and the breach area, and
  the support and breach force positions. They also consider establishing NFAs or RFAs around scouts or other
  observers, and RFLs for forces converging on the objective.
  6-138. The commander may give the priority of indirect fires to the unit most likely to encounter an
  obstacle. The FSE maintains a focus on the critical tasks and continuously adjusts the plan as required to
  accomplish the mission. FS planning guidelines for breaching operations include:
  * Use IPOE techniques to designate enemy high-value targets and identify HPTs for attack.
