Define Electronic Attack (EA) and differentiate between jamming and deception.

• A. EA is a purely defensive measure with no impact on spectrum; jamming and deception are both forms of encryption.
• B. EA entails only cyber operations with no RF component.
• C. EA aims to deny, degrade, or mislead an adversary’s use of the spectrum; jamming adds interference to degrade, while deception manipulates the perceived signals (e.g., spoofing ranges or velocities).
• D. EA is used to protect own sensors; jamming and deception are both passive.

Answer: (C)
