Which of the following is NOT a main action of electronic warfare?

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

Answer: (D)

In electronic warfare, actions are organized into three broad categories: electronic attack, electronic protection, and electronic support. Electronic attack covers active measures to degrade or deny an adversary’s use of the spectrum. Electronic protection focuses on defending our own systems from such interference. Electronic support involves gathering information about the battlespace, including surveillance of emissions and sensing the electromagnetic environment.

Jamming fits inside electronic attack as a method used to disrupt or degrade enemy communications and radar. It’s a specific technique within that category, not a separate main action itself. That’s why it isn’t listed as one of the main actions, whereas attack (electronic attack), defence (electronic protection), and surveillance (electronic support) represent the primary action areas.
