text: Fire Support in Depth During Large-Scale Combat Operations
  * Develop pre assault fire plan and any deception fires with joint and unified action partners and
  ensure all elements executing SEAD also understand the ground force commander's maneuver
  plan and HPTs.
  * Understand and communicate the JFC SEAD plan that will support the operation to the supported
  commander.
  * Make recommendations for priority of echeloning FS platforms into the lodgment over time.
  * Provide FS to the joint force operating in the land or maritime domain well beyond the established
  lodgement.
  * Ensure ISR assets are allocated.
  6-22. During the assault phase, the FS considerations include:
  * Understand the ground tactical plan.
  * Establish communications with SOF on the ground for ISR/target handover capabilities.
  * Account for the dense airspace utilizing airspace C2 and coordinating measures.
  * Strike enemy targets in the lodgment area simultaneously with enemy units that can reinforce or
  counterattack.
  * Position FA and mortars to support expansion of the lodgment and deconflict with potential
  ongoing air landings.
  * Decentralized execution of fires.
  6-23. During the third phase, stabilization of the lodgment FS considerations include:
  * Balance CAS, attack aviation, and AI capabilities as additional indirect FS systems arrive.
  * Deconfliction of the saturated airspace.
  * Begin moving FA and mortars with supported forces as lodgment expands.
  6-24. During the fourth phase, introduction of follow-on forces FS considerations include:
  * Utilize FS planning and execution principles to support ground offensives as additional maneuver
  forces arrive.
  * Be prepared to shift priority of fire.
  * Be prepared to shift boundaries and respective FSCMs.
  6-25. During the fifth phase termination or transition of operations FS considerations include:
  * Increase in nonlethal and information related capability options.
  * Redeployment of FA balanced with CAS and AI and attack aviation.
  6-26. Deep operations do not occur separately. They are conducted simultaneously with operations in the
  close and rear areas. These operations are conducted to protect forces, provide freedom of maneuver, and
  facilitate operations in the close area. The following sections will describe the defense and offense in the
  close area and FS considerations of each.
  SECTION III – THE DEFENSE
  6-27. While the offense is more decisive, the defense is usually stronger. The conduct of the defense alone
  normally cannot determine the outcome of battles. The purpose of the defense is to create conditions for the
  offense that allows Army forces to regain the initiative.
  6-28. A defensive operation is an operation to defeat an enemy attack, gain time, economize forces, and
  develop conditions favorable for offensive or stability operations (ADP 3-0). The defense is what provides
  time for a commander to build combat power and establish conditions to transition to the offense. The defense
  is ideally a shield behind which a commander maintains or regains the initiative. Initially, a defending
  commander is likely to be at a relative disadvantage against an attacking enemy since and enemy can choose
  when and where to strike.
  6-29. A defending force does not wait to be attacked, it aggressively seeks ways to attrit and weaken enemy
  forces before combat begins. A defending force attacks enemy forces at every opportunity and seeks every
  opportunity to transition to the offense. FS is a primary means for the maneuver commander to continually
