  The G-3 (S-3)
  A-19. The G-3 (S-3) is the staff lead in planning and the conduct of Army operations. During the planning
  and execution of EW and signal support, the G-3 (S-3)—
  * Exercises staff responsibility for electronic protection.
  * Includes electronic warfare support and electronic attack scenarios in all command post and field
  training exercises.
  * Evaluates electronic protection techniques employed.
  * Includes electronic protection in the unit training program.
  Cyber Electronic Warfare Officer
  A-20. The cyber electronic warfare officer plans, coordinates, and directs the execution of EW activities. The
  cyber electronic warfare officer is also the lead for the CEMA section. The cyber electronic warfare officer—
  * Serves as subject matter expert on enemy EW capabilities and EW rules of engagement.
  * Leads the EW working group.
  * Submits information requirements to the G-2 (S-2) to support EW planning and assessment.
  * Supports the G-2 (S-2) during intelligence preparation of the battlefield.
  * Coordinates with the G-6 (S-6) to plan, implement, and assess friendly electronic protection
  measures.
  * Coordinates with the G-6 (S-6) spectrum manager to ensure planned EW activities do not interfere
  with friendly communications.
  * Deconflicts EW operations with the spectrum manager in the CEMA section.
  * Collaborates with the G-2 (S-2) to synchronize and deconflict EW operations with intelligence
  activities.
  G-2 (S-2)
  A-21. The G-2 (S-2) provides current intelligence estimates during the military decision-making process, and
  updated estimates during operations. The intelligence estimate includes—
  * Current enemy tactics, techniques, and procedures.
  * Enemy locations in relation to friendly forces.
  * The enemy’s electronic technical data—enemy capabilities that could be used to deny friendly use
  of the electromagnetic spectrum.
  * Known cyberspace threats to inform cybersecurity and defensive cyberspace operations efforts.
  RECOGNIZING AND RESPONDING TO THREAT EFFECTS
  A-22. Because peer threats consider friendly command and control capabilities to be high priority targets,
  they have developed capabilities to deny their enemies the effective use of the electromagnetic spectrum for
  communications. Signal personnel and leaders must learn to identify and respond to threat effects in
  cyberspace and the electromagnetic spectrum.
  ELECTROMAGNETIC SPECTRUM (JAMMING)
  A-23. Electromagnetic jamming is the deliberate radiation, reradiation, or reflection of electromagnetic
  energy for the purpose of preventing or reducing an enemy’s effective use of the electromagnetic spectrum,
  and with the intent of degrading or neutralizing the enemy’s combat capability (JP 3-13.1). Jamming is an
  effective way for the enemy to disrupt friendly communications. An enemy only needs a transmitter tuned to
  a U.S. frequency with enough power to overpower friendly signals can effectively jam U.S. systems.
  A-24. Jammers operate against receivers, not transmitters. The two modes of jamming are spot and barrage
  jamming. Spot jamming concentrates power on one channel or frequency. Barrage jamming is power spread
  over several frequencies or channels at the same time. It is important to recognize jamming, but it can be
  difficult to detect.
