Which is an advantage of Passive Electronic Attack?

• A. Cannot be directly detected by the enemy
• B. Can be easily detected by the enemy
• C. Requires active emission
• D. Shortens detection range

Answer: (A)

Passive Electronic Attack gains its advantage from not radiating energy. Because there are no intentional emissions, the enemy cannot directly detect or locate you using their RF sensors, which keeps your position hidden and reduces the chance of counter-detection. This stealth aspect is what makes passive methods appealing when you want to influence or disrupt the adversary without giving away your presence. In contrast, active behavior that produces jamming or deceptive signals creates emissions that adversaries can detect and sometimes trace, making the operation more vulnerable to countermeasures. Since there is no emission, this approach also does not shorten your own detection range; it tends to preserve your stealth rather than reveal it. The other statements contradict the nature of passive electronic attack: it does not require active emission, and it is not easily detected by the enemy.
