text: Fire Support and the Operations Process
  division is responsible for orchestrating the division counterfire effort. When a FAB from corps is available
  to the division, the DIVARTY commander may assign it the counterfire role. Responsibility for the execution
  of the division counterfire effort, however, remains with the DIVARTY commander.
  PROACTIVE COUNTERFIRE
  3-25. Proactive counterfire is the specific targeting of enemy indirect fire systems including their C2, sensors,
  platforms, and logistics before they engage friendly forces. The goal of proactive counterfire is to identify,
  locate, and attack to eliminate the enemy's strike capability before it can impact friendly operations. The
  proactive measures consist of zone management, site analysis, and position survivability considerations. The
  proactive counterfire process begins with targeting and continues throughout the operation. The G-2 and the
  targeting officer develop named areas of interest and target areas of interest where the enemy indirect fire
  assets are expected. Rocket BNs from the FAB and AI aircraft normally perform the bulk of proactive
  counterfire in support of division operations, using TA and fires as well as allocated, joint, national, or
  multinational assets to acquire and disable attack components of the enemy's strike capability. Examples of
  target sets include cannon, rocket, and missile delivery units, prepared launch sites, artillery ammunition
  storage facilities, FDCs, counterfire radars, FOs, fixed or rotary wing airfields and fire support
  communication infrastructure. Information collection assets must be synchronized and integrated to
  accurately locate targets; and attack assets (such as artillery, mortars, CAS, attack helicopters, naval surface
  fire support, and CEMA) must be dedicated against the threat total FS system. Considerations for conducting
  proactive counterfire include:
  * All available artillery units participate.
  * Integrate all available joint FS attack/delivery systems.
  * Requires augmentation by Army and joint collection assets to locate and accurately target the
  enemy indirect fire systems.
  * The G-2/S-2 typically has a leading role in managing this effort; intelligence feeds into common
  ground station and cross-cueing radars and UAS are critical.
  * Establishing digital interface between the MLRS/HIMARS and cannon FA BN S-2s and the S-
  2/liaisons is critical.
  * Making maximum use of permissive FSCMs to facilitate the clearance of fires; for example, in
  defense the fire support coordination line (FSCL) may be positioned close to friendly troops to
  facilitate quick engagements.
  * Managing no-fire areas (NFAs) that protect SOF, long-range surveillance detachments,
  reconnaissance troops, and scouts is critical.
  * Use of AFATDS to clear fires should be maximized.
  * Establishing radar zones as required.
  REACTIVE COUNTERFIRE
  3-26. Reactive counterfire provides immediate indirect and joint fires to neutralize, destroy, and suppress
  enemy indirect fire weapons once acquired. The FS system responds primarily to enemy mortar and artillery
  fires during or immediately following enemy engagement of friendly forces. Reactive counterfire usually
  requires quick response capabilities for optimum effectiveness and can benefit from the establishment of
  quick-fire channels.
  3-27. FA units employ a variety of counterfire acquisition assets to accurately locate enemy indirect fire
  assets as they are engaging friendly forces establishing sensor-to-shooter links to attack the enemy systems.
  Ensure that the mission fired report and artillery target intelligence is sent to the all-source analysis section.
  Other key considerations for conducting reactive counterfire include airspace clearance, the use of both
  permissive FSCMs that facilitate quick engagements and restrictive measures such as NFAs to protect critical
  assets, establishing quick-fire channels with sensor-to-shooter links, and designating radar zone managers.
