  IFC PLANNING
  7-33. An IFC commander and members of his staff conduct their planning in
  coordination with the rest of the OSC staff, concurrently with the OSC staff
  developing the operation plan. The IFC has targets for each phase of the
  battle. Planning considerations include target type, dimensions, degree of
  fortification, mobility, and depth into the enemy’s defense.
  Allocation Procedures
  7-34. The OPFOR carefully calculates fire support requirements in terms of
  weapons and munitions needed to produce a required effect on enemy targets.
  If insufficient fire support or ammunition is available to achieve the neces-
  sary result, the OPFOR does not fire less and hope for the best. Rather, if
  necessary, it engages fewer targets, adjusting the fire support plan and the
  operation plan.
  7-35. The priority of allocation of fire support assets to the OSC from the ad-
  ministrative force structure is normally to the OSC’s IFC. Fire support assets
  that are allocated to the OSC and not used in the IFC are allocated, normally
  in a constituent or dedicated relationship, to maneuver units such as DTGs.
  Fire support units remaining under IFC command may provide fires for tacti-
  cal maneuver units in a supporting relationship. The supporting relationship
  allows the IFC commander the flexibility to task fire support assets to engage
  key enemy targets throughout the AOR.
  Synchronization
  7-36. The IFC is synchronized at two levels. First, the OSC commander and his
  staff are responsible for synchronizing fire support with ground maneuver.
  The key element is to ensure that all fire support occurs at the right place
  and time to produce the desired effect. The OSC commander’s maneuver plan
  forms the basis for the synchronization of the IFC.
  7-37. The commanders of the individual fire support components accomplish
  the second level of synchronization when they plan and execute the fire sup-
  port operations. They must synchronize the supporting fire components to
  produce the concentration of combat power at the decisive point. For exam-
  ple, the priority of initial attack helicopter fires may be to suppress enemy air
  defense systems to protect attacking fixed-wing aircraft. The artillery may be
  assigned missions to attack targets to assist the attacking ingress and egress
  of aircraft.
  FIRE SUPPORT COORDINATION MEASURES
  7-38. Fires from mortars, cannon artillery, multiple rocket launchers (MRLs),
  and SSMs pose a potential hazard to friendly maneuver forces and aircraft
  activities. The highest probability of conflict between aircraft and indirect fire
  weapons occurs at relatively low altitudes in the immediate vicinity of firing
  positions and targeted areas. (See Chapter 8 for more information on air and
  artillery coordination measures.) To reduce potential conflicts between indi-
  rect fires and maneuver forces or aircraft, information pertaining to firing po-
  sitions, targeted areas, and fire support plans is distributed to all involved
