What is the primary purpose of Defensive Use of Electronic Warfare (EW)?

The primary purpose of Defensive Use of Electronic Warfare (EW) is to protect personnel and equipment from electromagnetic spectrum effects. Defensive EW involves employing measures that minimize the impact of enemy electronic capabilities, which can include jamming, deception, and protection against offensive electronic attacks. This focus on protection is crucial because, in a conflict, adversaries may use the electromagnetic spectrum to disrupt communications, navigation systems, and other vital operations.

By safeguarding against these potential disruptions, Defensive EW ensures that military forces can maintain operational effectiveness and mission readiness. The ability to defend against threats in the electromagnetic spectrum is essential for preserving the integrity of communication lines and safeguarding lives and resources on the battlefield.
