Which of the following is NOT a division of electronic warfare?

• A. Attack
• B. Protect
• C. Warfare Support
• D. Communications

Answer: (D)

Electronic warfare revolves around shaping the electromagnetic battlefield to favor friendly forces and hinder the enemy. It’s organized into three main families: Electronic Attack, which uses EM energy to degrade or deny enemy sensors and weapons; Electronic Protection, which defends our own systems from being jammed or spoofed; and Electronic Warfare Support, which involves intercepting and analyzing signals to gain intelligence and targeting information. Communications is a separate domain that deals with transmitting and receiving information; while it operates in the same spectrum and can be affected by EW, it is not itself a division of electronic warfare. So the option that isn’t a division is the communications domain.
