  Fire Support Coordination Measures
  FSCMs enable the employment of fires and effects. Locations and implementing
  instructions for FSCMs are disseminated electronically by message, database updates,
  or overlays through command and FS channels, to higher, lower, and adjacent
  maneuver and supporting units. The establishment or change of a FSCM is typically
  initiated through the operations cell and ultimately approved by the establishing
  commander. FSCMs enhance the expeditious engagement of targets; protect forces,
  populations, critical infrastructure, and sites of religious or cultural significance; and
  set the stage for future operations. The commander positions and adjusts FSCMs
  consistent with the operational situation and in consultation with superior, subordinate,
  supporting, and affected commanders. The operations cell informs coordination
  elements of the change and effective times. Conditions that dictate the change of
  FSCMs are also coordinated with the other agencies and components as appropriate.
  As conditions are met, the new FSCM effective time can be projected and announced.
  Following direction to execute the change, the current operations integration cell
  should confirm with all liaison elements that the FSCM changes have been
  disseminated.
  Note. The airspace coordinating and FSCM graphics depicted in this chapter are examples for
  illustrative purposes only. The authority for constructing such graphics is FM 1-02.2, JP 3-09, JP
  3-52, and Military Standard (MILSTD 2525).
  SECTION I – PERMISSIVE FIRE SUPPORT COORDINATION MEASURES
  B-1. Permissive FSCMs facilitate the attack of targets. Fires must be cleared with both terrain owners and
  other airspace users. FSCMs will change frequently during large-scale combat operations. The commander
  adjusts FSCMs as required to keep pace with operations.
  COORDINATED FIRE LINE
  B-2. A coordinated fire line is a line beyond which conventional surface-to-surface direct fire and indirect
  fire support means may fire at any time within the boundaries of the establishing headquarters without
  additional coordination but does not eliminate the responsibility to coordinate the airspace required to
  conduct the mission (JP 3-09). The purpose of the CFL is to expedite the surface-to-surface attack of targets
  beyond the CFL without coordination with the ground commander in whose area the targets are located. A
  brigade commander or equivalent, usually establishes the CFL, but it can be established by a BN with higher
  HQ approval. For example, in amphibious operations a maneuver BN could establish the CFL. The division
  or corps commander may reserve the right to establish or consolidate CFLs. Locate the CFL as close to the
  establishing unit as possible without interfering with the supported forces. The CFL does not eliminate the
  requirement or responsibility to coordinate the airspace required to conduct the mission. Such fires must still
  comply with ROE and law-of-war targeting constraints; designation of a CFL is not authorization to fire
  indiscriminately into the area. The CFL should be placed on identifiable terrain, however, additional
  considerations include the limits of ground observation, the location of the initial objectives in the offense,
  and the requirement for maximum flexibility in both maneuver and the delivery of supporting fires.
