  5-34. The commander, with the support of the staff, employs the appropriate combinations of mounted,
  dismounted,and aerial manned (and unmanned) reconnaissance (and surveillance) to obtain the information
  required to answer the CCIRs (priority intelligence requirements and friendly force information
  requirements) and to support the targeting process. At the same time,reconnaissance forces must be prepared
  to conduct counterreconnaissance (see paragraph 5-4) and continuously develop detailed information on both
  the enemy and terrain. Reconnaissance forces fight for information as in a reconnaissance in force (see
  paragraph 5-52) designed to discover or test the enemy’s strength,dispositions,and reactions.
  5-35. Surveillance complements and informs reconnaissance as reconnaissance complements and informs
  surveillance by cueing (see paragraph 5-64) the commitment of capabilities against specific locations or
  specially targeted enemy units. Throughout planning and preparation,the BCT S-3 and S-2 integrate actions
  within the BCT’s overall information collection plan (see paragraph4-146) and other higher and lateral
  information collection efforts to ensure that each asset is used effectively. The S-2 develops an initial
  synchronization plan to acquire information to help answer priority intelligence requirements based on the
  available reconnaissance and surveillance assets supporting the intelligence scheme of support. The S-3,in
  coordination with the commander,assigns specific intelligence acquisition tasks to specific units for action.
  5-36. The S-2 and S-3, in coordination with the rest of the staff, develop a synchronized and integrated
  information collection plan that satisfies the commander’s maneuver, targeting, and information
  requirements. Asstated earlier,the S-3 is overall responsible for the information collectionplan. The S-3 is
  also responsible for ground and air reconnaissance assets, which includes engineers, chemical, biological,
  radiological, and nuclear (CBRN), artillery, and Army attack reconnaissance aircraft. The S-2’s primary
  responsibility is to integrate ground surveillance systems and special electronics mission aircraft. The brigade
  civil affairs operations staff officer’s (S-9) primary responsibility is planning civil reconnaissance and the
  integration of civil informationinto the common operational picture (COP). The commander’s requirements,
  dictated by the mission variables of METT-TC,commonly include—
  (cid:122) Locations, composition, equipment, strengths, and weaknesses of the enemy force, to include
  high-priority targets and enemy reconnaissance, security,and surveillance capabilities.
  (cid:122) Locations of obstacles, prepared fighting positions, enemy engineer units, earth moving
  equipment,breaching assets,and barrier material.
  (cid:122) Probable locations of enemy reconnaissance objectives.
  (cid:122) Locations of possible enemy assembly areas.
  (cid:122) Locations of enemy indirect-fire weapon systems and units.
  (cid:122) Locations of gaps,assailable flanks,and other enemy weaknesses.
  (cid:122) Locations of areas for friendly and enemy air assault and parachute assault operations.
  (cid:122) Locations of enemy air defense gun and missile units and air defense radars.
  (cid:122) Locations of enemy EWunits.
  (cid:122) Effects of weather and terrain on current and projected operations.
  (cid:122) ASCOPErelated information about civilians located within the unit’s area of operations.
  (cid:122) Likely withdrawal routes for enemy forces.
  (cid:122) Anticipated timetable schedules for the enemy’s most likely COAand other probable COAs.
  (cid:122) Locations of enemy command and control centers, intelligence nodes, reconnaissance, security,
  and surveillance systems, and the frequencies used by the information systems linking these
  systems.
  (cid:122) Locations of enemy sustainment assets.
  5-37. When reconnaissance forces (and surveillance assets) cannot answer the commander’s information
  requirements. The commander’s options include—
  (cid:122) The S-2 sending a request for information to higher and adjacent units.
  (cid:122) The commander committing additional resources.
  (cid:122) The commander deciding to execute task with the current information.
  5-38. CBRN reconnaissance and surveillance is the detection, identification, reporting, and marking of
  CBRN hazards. CBRN reconnaissance consists of search,survey,surveillance,and sampling operations. Due
  to limited availability and number of the CBRN reconnaissance vehicles within the BCT, the commander
