Which action is intended to disrupt or deny the enemy's use of the electromagnetic spectrum?

• A. Attack
• B. Defence
• C. Surveillance
• D. Support

Answer: (A)

Disrupting or denying the enemy’s use of the electromagnetic spectrum is a core aim of electronic warfare, and the action that directly accomplishes this is attack. By attacking, forces actively target and degrade or destroy enemy emitters and systems—jamming their communications, spoofing signals, or destroying radars and navigation aids—so they can’t reliably use the spectrum to coordinate, detect, or navigate. Defense, on the other hand, is about protecting our own systems and ensuring resiliency. Surveillance involves observing and collecting information about emissions rather than interfering. Support provides assistance to allied forces and missions and isn’t primarily about denying the enemy spectrum.
