Which term is used to describe electronic counter measures used in warfare?

The term used to describe electronic countermeasures employed in warfare is known as Electronic Warfare. This encompasses a range of tactics and techniques utilized to manipulate the electromagnetic spectrum to gain a strategic advantage over adversaries. Electronic warfare can include actions to disrupt or deceive enemy communications, radar, and other electronic systems, ultimately enhancing the operational effectiveness of friendly forces while degrading that of opponents.

In contrast, Cyber Defense focuses specifically on protecting computer systems and networks from cyber threats rather than engaging in electronic countermeasures. Information Operations, while encompassing various methods of influencing and disrupting an adversary’s information capabilities, is broader and includes psychological operations and public affairs, not limited to electronic means. Signal Intelligence refers to the gathering and analysis of intercepted signals, which is a crucial component of intelligence operations but does not directly involve countermeasures or the active disruption of enemy electronic systems.
