  CENTRALIZEDCOORDINATION
  5-54. Due to the nature of the airhead and the required continuous airflow into the airhead, fire support
  assets must be closely controlled to prevent fratricide and waste of assets. During the initial stages of an
  airborne operation and before adequate ground communications can be established, coordination and
  controloffiresupportareaccomplishedfromanairborneplatform.
  5-55. On landing, each battalion/squadron or BCT or regimental headquarters establishes contact with the
  airborne platform or joint airborne communications center/command post (JACC/CP) through the TACP.
  Firesupport,suchascloseairsupport,beyond thatavailable fromorganicordirectsupport assetswouldbe
  requested from the airborne platform. Prioritizing and coordinating requests are accomplished by the
  groundforcecommander’srepresentativeintheairborneplatform.Hisresponsibilitiesincludethefollowing:

  5-56. For air missions, the commander’s staff establishes contact with the appropriate flight, provides
  essential information, and then hands the flight off to the appropriate TACP or forward air controller for
  mission execution. At that point, the mission is conducted the same way as conventional operations. If
  naval gunfire or air support isavailable, it isessentialthat a navalgunfire liaisonofficer be presentinthe
  airborneplatformtoperform a similarfunction.
  5-57. Once adequate facilities have been established in the airhead, fire support coordination
  responsibilitiesare passed fromthe airborne platform to the ground commander and his staff. (There isno

  COORDINATIONMEASURES
  5-58. The ABNAFC, assigned an area of operation within the airhead, employs fire support coordination
  measures (FSCMs) to facilitate rapid target engagement while simultaneously providing safeguards for
  friendly forces. Boundaries are the basic FSCM. The fire support coordinator recommends additional
  FSCMs to the commander based on the commander’s guidance, location of friendly forces, scheme of
  maneuver,andanticipatedenemyactions.FSCMsareeitherpermissiveorrestrictive.
  5-59. The primary purpose of permissive measures is to facilitate the attack of targets. Once they are
  established, further coordination is not required to engage targets affected by the measures. Permissive
  FSCMs include a coordinated fire line (CFL), a fire support coordination line (FSCL), and a free -fire
  area(FFA).
  5-60. Theprimarypurposeofrestrictive measures istoprovidesafeguards forfriendlyforces. A restrictive
  FSCM prevents fires into or beyond the control measure without detailed coordination. Restrictive FSCM
  include an airspace coordination area, a no-fire area (NFA), a restrictive fire area (RFA), and a restrictive
  fire line (RFL). Establishing a restrictive measure imposes certain requirements for specific coordination
  before the engagement of those targets affected by the measure. (Refer to FM 3-90-1 for a detailed
  discussionofFSCMs.)
