Which intelligence type uses intercepted electromagnetic emissions?

The correct answer is Signals Intelligence (SIGINT), as it specifically involves the collection and analysis of intercepted electromagnetic emissions. This form of intelligence primarily focuses on two categories: Communications Intelligence (COMINT), which deals with the interception of voice and data communications, and Electronics Intelligence (ELINT), which relates to the analysis of non-communication signals, such as those emitted by radar systems. However, SIGINT serves as the broader umbrella that encompasses both COMINT and ELINT, making it the correct choice when referring to intelligence types that leverage intercepted electromagnetic emissions.

Understanding the nuances between these categories is crucial for distinguishing how each type of intelligence contributes to overall situational awareness and strategic operations.
