  Counterfire is tied to current and future operations and is part of the overall combined arms fight to achieve
  fire superiority.
  3-22. In large-scale combat operations, the corps commander is responsible for counterfire throughout the
  depth of the corps AO. They determine the best way to protect the corps combat forces and to defeat, delay,
  or disrupt the threat array. This estimate or analysis includes an assessment of the counterfire capabilities of
  the corps and its subordinate divisions. For more information on corps operations see ATP 3-92. The corps
  commander's counterfire responsibilities include the following:
  * Segmenting the battlefield by delineating maneuver boundaries and assigning areas of
  responsibility for corps and its subordinate divisions. This helps establish the delineation of
  counterfire responsibilities within the corps zone.
  * Assigning missions and responsibilities, to include specific requirements to information collection
  assets through the collection manager.
  * Allocating resources. Corps assets may be retained at corps or allocated to subordinate divisions.
  Conversely, in some situations, the corps commander may require the use of division assets to
  support a corps counterfire responsibility. They should provide guidance for use of certain critical
  assets such as the any corps aviation assets, AI, ISR capabilities, SOF, and CEMA resources.
  * Requesting additional TA and attack/delivery systems from theater or JTF level or from other joint
  HQ.
  * Detecting and attacking. The corps detects and attacks targets within its AOR, the corps also may
  attack targets within a division AO when the division has forwarded such a request to corps based
  on priority and need. Within its capability, the corps may respond to requests for additional fires
  from adjacent units.
  * Assessing. Finally, the corps commander must assess the protection of his combat units and the
  effects of counterfire against threat fire support systems. As appropriate, commander adjusts
  information collection and/or attack priorities for protection of his force and attack of enemy
  targets. Commander may reallocate assets and modify the missions of subordinate units.
  3-23. The corps commander decides how the corps will conduct counterfire operations. They influence how
  subordinate division commanders fight through the allocation of corps assets, the issuance of attack guidance,
  and the identification of corps HPTs. The corps commander can support a division commander's counterfire
  efforts by attacking threat fire support systems at depth; by setting the conditions division counterfire fight.
  In addition to allocating assets to divisions, the corps commander can further support a division counterfire
  fight by responding to the division requests with AI, MLRS, CEMA, and EW. With respect to counterfire in
  the division AO, the corps commander:
  * Assigns missions to division and corps fire support assets and delineates their areas of
  responsibility by establishing boundaries.
  * Detects and attacks targets forwarded by the division. As appropriate, the corps, after coordinating
  with the division FSE, may attack threat fire support targets within the division zone by massing
  fires to achieve required effects. Procedures for attacking threat systems firing from across
  boundaries also must be coordinated.
  * Task-organizes and allocates assets based on the commander's intent and the mission variables of
  mission, enemy, terrain and weather, troops and support available, time available, and civil
  considerations, each of which have informational considerations (METT-TC (I)), the corps
  commander can give the divisions' added assets for detection and attack of threat fire support.
  Most often, corps provides non divisional FA delivery assets to augment DIVARTY fire support
  capabilities. This can be done by either of the following actions:
  * Assigning a FAB, a support relationship of R or GSR to a DIVARTY.
  * Attaching the FAB to the division requiring augmentation. The FAB is normally further attached
  to the DIVARTY.
  3-24. Typically, most of the reactive counterfire fight takes place within the division AO. Most of the threat
  active fire support systems are in this area. The responsibilities of the division commander mirror those of
  the corps commander. Although his assets are fewer in number and variety, the division commander does
  have organic TA, target processing, and delivery assets to conduct counterfire. The FSCOORD for the
