  * Conducting technical fire direction.
  * Giving fire orders to the firing element if necessary.
  * Delivering the required ordnance on the target to create the desired effect on target (deliver fires).
  * Determining and reporting effects on the engaged target.
  4-83. A fire mission is the specific assignment given to a fire unit as part of a definite plan; an order used to
  alert the weapon/battery area and indicate that the message following is a call for fire (TC 3-09.81). FA BN
  functions directly associated with surface-to-surface attack are encompassed in the fire mission process. The
  FSE or any sensor can initiate a fire mission (for example, FOs, aerial observers, radars). Quick-fire channels
  can be established for any observer or sensor. Any brigade or BN FSE or FA CP that is normally in the fire
  mission flow, but is bypassed during quickfire operations, should receive a notification of each fire mission
  through message of interest processing. To expedite fires, the unit can coordinate the use of various quick-
  fire linkages, designed to facilitate rapid mission execution, while achieving desired control. For example, a
  quick-fire channel could be established from a FIST, through the BN FSE, and then directly to the FA BN
  FDC. For even faster response and more decentralized control, the FIST may send the mission directly to the
  FDC that will execute the mission. This is often used for priority targets and FPF.
  4-84. A priority target is a target, based on either time or importance, on which the delivery of fires
  takes precedence for the designated firing unit or element. An artillery firing unit prepares to engage its
  priority target by laying its weapon(s) on the assigned target whenever the firing unit is not engaged in a fire
  mission in order to reduce the time required to fire the target. For example, a FPF is a priority target. The
  supported commander, after consultation with his FSO, designates priority targets. The supported
  commander also gives specific guidance as to when the targets will become priority, the munitions to use,
  the accuracy required, and the desired effects. The supported commander designates a priority target based
  on time requirements or target importance. When not engaged in fire missions, firing units lay on priority
  targets. The purpose of laying on a target is to direct or adjust the aim of a weapon, or setting of a weapon
  for a given range, deflection, or both.
  4-85. FA BNs normally do not perform airspace deconfliction; instead, the air defense airspace management
  /brigade aviation element in coordination with the division JAGIC executes this process for the supported
  commander.
  4-86. The FA BN primarily uses digital means to plan and execute fires. However, the BN may receive
  planned and immediate fire missions from a wide variety of sources, in both voice and digital formats. These
  requests may have been generated by lower or higher echelon FSE and by trained FA observers and untrained
  observers. UAS may send calls for fire directly to the brigade FSE as the aircraft may be considered a brigade
  asset.
  DIGITAL FIRE REQUESTS
  4-87. Digital fire missions may be received from FA and non-FA digital systems. Procedures and capabilities
  may vary depending on which digital systems are interfacing with one another. Training opportunities should
  be aggressively sought out. FA technical rehearsals should thoroughly address digital interface issues.
  Whenever possible, digital fire missions should be rehearsed along the entire data link, under the same digital
  conditions anticipated for the actual operation (for example, extended communications distances, surge
  digital traffic capacity, degraded operations, and alternate routes).
  VOICE FIRE REQUESTS
  4-88. Use of voice may be necessary for unplanned, immediate fire requests or during denied, disrupted,
  degraded operations. FDCs must anticipate the circumstances and the types of voice missions they may
  encounter. The tactical solution and effects on the target should be essentially the same regardless of whether
  the mission is processed voice or digital. However, missions from untrained observers must be rehearsed
  during training to establish proper unit techniques.
