What is the definition of Military action to exploit the EM spectrum including the search for, intercept, and identification of EM emissions?

The definition of military action that involves exploiting the electromagnetic (EM) spectrum through the search for, interception, and identification of EM emissions aligns with the broader concept of Electronic Warfare (EW). This term encompasses all actions taken in the EM spectrum to achieve military objectives, which includes not only the tactics of identifying and exploiting enemy emissions but also the various means of jamming or disrupting them.

Understanding the context behind Electronic Warfare is crucial. EW can be broken down into specific categories, including Electronic Attack, Electronic Protection, and Electronic Warfare Support. While these subcategories focus on specific actions—such as attacking an enemy's electronic systems or protecting friendly systems—the overarching term encompasses all activities involving the use of the EM spectrum. Therefore, when considering the full scope of military actions aimed at effectively leveraging EM emissions for operational advantage, Electronic Warfare is the most appropriate and comprehensive choice.
