  operations.
  Table 8-5. IPOE and information requirements associated with offensive operations (friendly)
  Determine the likely purpose and type of enemy defense: area defense, mobile defense, or retrograde.
  Determine the likely enemy’s likely end state, objectives, decision points, culmination point, strengths, vulnerabilities, and scheme of maneuver.
  Synchronize efforts to gain and maintain relative advantages and maintain tempo.
  Identify military aspects of terrain (OAKOC) and weather effects that support enemy defensive operations:
  • Terrain that allows reconnaissance and security outposts to be arranged in depth along choke points and terrain features that canalize friendly
  forces to attrite our forces and diminish our combat power in depth.
  • Terrain, including subterranean, that allows the enemy to tie obstacles to existing terrain features to support enemy defensive positions. (See
  ATP 3-21.51.)
  • Favorable air and ground avenues of approach for an enemy counterattack (including for the use of drone swarms and drone delivered munitions).
  • Terrain that canalizes friendly attacking forces.
  • Favorable weather effects (such as visibility, wind, precipitation, cloud cover/ceilings, temperature, thermal crossover, humidity, and atmospheric
  pressure) for enemy systems relative to friendly systems.
  Identify terrain military aspects of terrain (OAKOC) and weather effects that support friendly offensive operations:
  • Favorable ground and air mobility corridors.
  • Areas with significant concealment and/or cover.
  • Terrain that allows forces to bypass obstacles and enemy positions.
  • Infiltration routes.
  • Landing zones (manned and unmanned aircraft systems).
  • Favorable weather effects (such as visibility, wind, precipitation, cloud cover/ceilings, temperature, thermal crossover, humidity, and atmospheric
  pressure) for friendly systems relative to enemy systems, and favorable weather for using obscuration or chemical weapons.
  Identify the location and orientation of enemy counterreconnaissance and security units, obstacles, engagement areas, main battle areas, reserve
  units, and likely counterattack routes (most incorporate intelligence handover lines).
  Within each enemy defensive area, identify specific primary, secondary, tertiary locations of enemy infantry, armor, antitank, mortar, and other units
  and systems, and the potential use of camouflage.
  Determine the likely use and identify the location of enemy command and control nodes, reconnaissance and surveillance assets, long-range
  fires, artillery and rocket units, air defense systems, rotary aviation units, close air support, engineer units, ammunition and logistics nodes,
  CBRN units, electromagnetic warfare assets, and special operations forces.
  Determine the likely use of enemy information warfare, cyberattacks, and denial and deception operations; likely impacts to friendly, threat, and
  neutral forces; and impacts of misinformation and disinformation on local, regional, and international audiences.
  Determine the impact of significant civil considerations on friendly and enemy operations such as hindering movement on lines of communications, medical
  and health considerations, criminal activity, and the housing and feeding of a displaced population.

  8-87. Table 8-6 depicts IPOE and information requirements generally associated with each of the four types
  of friendly offensive operations.
  Table 8-6. IPOE and information requirements associated with each offensive operation type
  Movement to contact
  A thorough IPOE and war-gaming effort indicates areas where contact with the enemy is likely as well as friendly and enemy vulnerabilities by
  phase of the operation. Besides the IPOE and information requirements identified in table 8-5, movement to contact includes considering the
  following requirements:
  • Intent and likely locations for enemy reconnaissance and security • Likely enemy use of a feint or deception.
  forces. • Indications that the enemy is still conducting movement. This could
  • Likely observation post locations. turn the operation into a meeting engagement or cause friendly
  • Likely enemy defensive locations with close obstacles and forces to employ a hasty defense.
  engagement areas. • Likely electromagnetic warfare, cyberspace, and space targets as
  • Likely enemy activities in friendly rear areas. well as the type and disposition of sensors in each domain.
  Attack
  Besides IPOE and information requirements, attack includes considering the following requirements:
  • Known and likely enemy defensive locations with likely purpose and use of close obstacles and engagement areas.
  • Known and likely enemy command and control and communications nodes and systems.
  • Known and likely electromagnetic warfare, cyberspace, and space targets.
  Exploitation
  Besides IPOE and information requirements, exploitation includes considering the following requirements:
  • Likely locations where friendly forces can interdict enemy reinforcements or second echelon forces through fires and subsequent operations.
  • Enemy reserve or second echelon and logistic units.
  • Enemy long-range artillery, missile systems, and associated fires units.
