Which term describes defensive capabilities designed to withstand and mitigate electronic warfare effects?

• A. Electronic Counter Measures
• B. Electronic Protective Measures
• C. Electronic Support Measures
• D. Electronic Attack Measures

Answer: (B)

Electronic Protective Measures are the defensive capabilities designed to withstand and mitigate electronic warfare effects. They focus on preserving mission capability when faced with jamming, deception, or other spectrum hazards by making systems more resilient and harder to disrupt. This includes techniques like frequency hopping and spread spectrum to avoid persistent interference, robust modulation and coding to maintain links under poor conditions, shielding and rugged hardware to handle EMI, and providing redundant communications paths or antenna diversity to keep critical links alive. In contrast, Electronic Counter Measures are about actively interfering with or deceiving the enemy’s use of the spectrum, Electronic Support Measures gather information about emitters to assess threats, and Electronic Attack Measures aim to degrade or destroy the enemy’s EW capabilities. The defensive nature of protecting operations under EW aligns with Electronic Protective Measures.
