  EXTERNAL COORDINATION
  5-19. External coordination includes coordinating with or among subordinate units and higher headquarters,
  as well as IO support units, IRCs, and resources that may not be under the unit's control during planning but
  are necessary to execute the plan. External coordination also includes coordinating with adjacent units or
  agencies. (Adjacent refers to any organization that can affect a unit's operations in and through the
  information environment.) This coordination is necessary to integrate IO throughout the force. Examples of
  external coordination include:
  * Assessing unit OPSEC posture.
  * Making sure the military deception operation is tracking with preparation for the overall operation.
  * Periodically validating assumptions.
  * Ensuring military deception operations are synchronized with those of higher, lower, and adjacent
  units.
  5-20. The IO officer remains aware of the effectiveness of cybersecurity tasks taken by the G-6 (S-6). Proper
  protection of plans and orders, and refinements to them, are essential during operations.
  5-21. Coordination with joint, interorganizational, and multinational partners is essential to the conduct of
  IO, as these entities and organizations affect the information environment and are affected by it. The IO
  working group is the primary means for this coordination but direct, face-to-face coordination is frequently
  necessary to ensure unity of effort.
  LIAISON
  5-22. Establishing and maintaining liaison is one of the most important means of external coordination. The
  IO officer may perform direct liaison but units may select another staff member to be part of the liaison team.
  Establishing liaison during planning enhances subsequent coordination during preparation and execution.
  5-23. Practical liaison can be achieved through personal contact between IO officers or between the IO
  officer and agencies/organizations involved in affecting the information environment. This coordination is
  accomplished through exchanging personnel, through agreement on mutual support between adjacent units
  or organizations, or by a combination of these means. Liaison should, when possible, be reciprocal between
  higher, lower, and adjacent units/organizations. Liaison must be reciprocal between IO sections when U.S.
  forces are operating with or adjacent to multinational partners.
  5-24. Liaison also has a force protection mission. Where host-nation security forces retain some operational
  capability, liaison is vital to coordinate actions. They provide intelligence and other related information about
  conditions in-theater.
  INITIATE INFORMATION COLLECTION
  5-25. Execution requires accurate, up-to-date situational awareness. During preparation, the IO officer
  updates IRs to ensure the most current information possible. The IO officer also works with the G-2 (S-2) to
  update collection asset taskings necessary to assess IO.
