text: Fighting for Intelligence During Large-Scale Combat Operations
  INTELLIGENCE SUPPORT TO DEFENSIVE OPERATIONS
  8-66. Before a battle, commanders at all echelons require intelligence and combat information. IPOE and
  information requirements may include—
  ⚫ The composition, equipment, intent, strengths, vulnerabilities, and scheme of maneuver of the
  attacking enemy force.
  ⚫ The location, direction, and speed of enemy reconnaissance elements.
  ⚫ The location and activities of enemy units and reserves.
  ⚫ Enemy C2 and communications facilities.
  ⚫ The location of enemy fire support and air defense systems with associated C2 networks.
  8-67. The G-2 uses the operations process’ prepare activity to complete information collection integration and
  synchronization. Corps and divisions rely on joint and national systems to detect and track targets beyond their
  limited organic capabilities. The corps headquarters employs available collection assets to refine its knowledge
  of the terrain, weather, and civil considerations within the area of influence. Collection assets identify friendly
  vulnerabilities and key defensible terrain. The division headquarters conducts periodic information collection
  of any unassigned areas to prevent the enemy from exploiting those areas to achieve surprise.
  8-68. Commanders continuously refine the enemy portion of the COP throughout their AOIs as part of deep
  operations. They focus their information collection efforts on key geographical areas and enemy capabilities
  of particular concern using NAIs. Figure 8-4 depicts a situation template of enemy forces in an offensive
  operation; the friendly forces in figure 8-4 provide context.
  8-69. Surveillance of the AOIs and effective reconnaissance are necessary to acquire targets and to verify
  and evaluate potential enemy COAs and capabilities. Information collection efforts focus on validating when,
  where, and with what strength the enemy will attack. This allows commanders to identify opportune times to
  conduct spoiling attacks and reposition forces.
  8-70. Intelligence supports friendly force efforts to protect the force, disburse and reassemble the force as
  necessary, and answer requirements on when, where, and in what strength the enemy will attack. This
  intelligence supports decisions on setting the defense, employing various capabilities, repositioning forces,
  conducting counterattacks, and when possible, transitioning to offensive operations.
