What is the definition of electronic warfare?

• A. The use of cyber tools to steal data
• B. Using electromagnetic spectrum capabilities to disrupt adversaries
• C. A strategy for ground troop engagement
• D. Negotiating peace with electronic contracts

Answer: (B)

Electronic warfare centers on using the electromagnetic spectrum to influence and disrupt the enemy’s operations. The best answer captures this by describing how electromagnetic spectrum capabilities are used to disrupt adversaries, which is the essence of EW—denying or degrading the enemy’s use of sensors, communications, and navigation while protecting one’s own forces. For example, jamming a radar or GPS signal, or spoofing sensor information, are classic EW actions that impair the opponent’s battlefield effectiveness. The other options describe cyber data theft, conventional ground strategy, or purely contractual negotiations, none of which involve leveraging the electromagnetic spectrum to affect the opponent’s military capabilities.
