text: Fire Support and the Operations Process
  large-scale combat operations, the minimum adequate FA support for committed units is normally
  one FA BN for each committed brigade.
  * Weight to the main effort. The main effort is a designated subordinate unit whose mission at a
  given point in time is most critical to overall mission success (ADP 3-0). The purpose for
  weighting the main effort is to concentrate the effects of combat power at the most advantageous
  place and time. The main effort can be weighted in a variety of ways. The main effort or the
  decisive operation can be weighted in a variety of ways with FS:
   Allocation of additional lethal and nonlethal FS attack/delivery systems.
   Command and support relationships designated to expedite execution of attack.
   Ammunition allocation.
   Focused TA assets.
   Priorities of fires.
  * Immediately available fire support for the commander to influence the operation. This can be
  accomplished through proper allocation of CAS, armed UAS, and attack aviation retained by the
  appropriate commander. Sufficient FS resources to include FA are normally retained under
  centralized control to concentrate fires at the decisive place and time. Establish FA support
  relationships of GS and GSR (discussed in Chapter 4) to enhance flexibility and facilitate the
  ability to provide immediately responsive fires. The supported commander lifts or shifts the
  priority of fires to exploit opportunities as they are presented. This is essential to ensure success
  in the face of unforeseen events.
  * Facilitate future operations. To ensure smooth transition from one phase of an operation to another
  during execution and planning. This principle can be implemented through the assignment of
  command and support relationships, positioning of artillery, positioning of ammunition, and
  positioning of TA assets. The assignment of an on-order mission or command and support
  relationship allows a unit to anticipate FS attack/delivery system support need in a future situation.
  Applying limitations on ammunition expenditure in an earlier phase of an operation in order to
  support the future main effort is another way of facilitating future operations.
  * Maximum feasible centralized control. The optimum degree of centralized control varies with
  each tactical situation. A higher degree of centralized control may be appropriate in a defensive
  situation, since the enemy has the initiative, and it is difficult to accurately predict where and when
  they will attack. The FSCOORD must anticipate and plan for the transition to offensive operations
  for a lesser degree of centralized control because the supported force has the initiative.
  * Never leave artillery in reserve. In large-scale combat operations, commanders (advised by their
  FSCOORDs) ensure FA units (MLRS, HIMARS, and cannons) always remain in the fight. This
  is accomplished by continuously adapting command and support relationships and also by
  continuously repositioning fires capabilities to create desired effects. Refer to the principle of
  "facilitate future operations" when applying this execution principle.
  INTEGRATION OF FIRE SUPPORT AND AIRSPACE
  CONTROL/MANAGEMENT DURING EXECUTION
  3-97. Airspace control is the exercise of delegated authority over designated airspace and users through
  control procedures and coordination measures to maximize operational effectiveness (JP 3-52). Airspace
  control relies upon airspace management capabilities provided by airspace control elements. Plans and
  procedures that support airspace control and airspace management activities are addressed throughout the
  operations process and are approved by the JFC or the designated airspace control authority. An airspace
  control system that promotes decentralized execution by utilizing the capabilities of airspace control elements
  in assigned sectors improves responsiveness and flexibility to rapidly execute fire missions and coordinate
  airspace users' activities inside a manageable volume of airspace.
  3-98. Clearance of fires during current operations are streamlined when ground force commanders properly
  plan for airspace use and implement the JAGIC TTP. The JAGIC is recognized by the joint force as an
  airspace control element of the airspace control system with delegated decentralized execution authority
  inside an assigned volume of airspace. The Army primarily uses procedural control to control forces and
