Which sub-discipline of SIGINT involves intercepting non-communications radiations?

• A. COMINT
• B. MASINT
• C. ELINT
• D. FISINT

Answer: (C)

The sub-discipline of SIGINT that involves intercepting non-communications radiations is known as ELINT, which stands for Electronic Intelligence. ELINT specifically focuses on the collection and analysis of data from electronic signals that are not used for communication purposes, such as radar signals or other electronic emissions. This is crucial for understanding enemy radar capabilities, weapon systems, and for overall threat assessment. Knowing the nuances between various SIGINT sub-disciplines is important. While COMINT deals specifically with communications intelligence—eavesdropping on voice and data communications—MASINT (Measurement and Signature Intelligence) encompasses a broader range of phenomena including signatures from weapons and atmospheric data. FISINT (Foreign Instrumentation Signals Intelligence) focuses on the interception of telemetry and other signals from foreign weapon systems during testing or deployment. Recognizing that ELINT is dedicated to non-communications emissions helps clarify its distinct role in the intelligence community, as it contributes significantly to the operational picture by identifying potential threats and enhancing situational awareness.
