Which term denotes measures that protect and sustain friendly systems during electronic warfare?

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

Answer: (B)

Electronic Protective Measures are the actions designed to keep friendly systems functioning in an electronic warfare environment. They focus on the survivability and continuity of operations for radios, sensors, and command-and-control links by reducing susceptibility to jamming, spoofing, and other electromagnetic effects. This includes techniques such as frequency agility and spread-spectrum approaches, shielding and hardening of equipment, redundant communication paths, antenna diversity, and robust error protection and encryption so missions can continue even under EW pressure. The other terms describe different parts of electronic warfare: Electronic Counter Measures aim to degrade or deny the enemy’s use of the spectrum; Electronic Support Measures gather information on emitters to support decisions; Electronic Attack Measures directly degrade or destroy enemy systems. Therefore, the term that denotes measures to protect and sustain friendly systems is Electronic Protective Measures.
