Which is intelligence produced by exploiting foreign communications systems and noncommunications emitters?

• A. COMINT - communications intelligence
• B. ELINT - electronic intelligence
• C. SIGINT - signals intelligence
• D. FISINT - foreign instrumentation signals intelligence

Answer: (C)

Signals intelligence is the collection and analysis of foreign signals to derive information. It includes two main streams: communications intelligence, which comes from intercepting foreign communications such as voice or data transmissions, and electronic intelligence, which comes from noncommunication emitters like radar, navigation signals, and other electronic emissions. Foreign instrumentation signals intelligence is a specialized subset that focuses on telemetry and other instrumentation signals from foreign platforms. When a prompt describes intelligence produced by exploiting both foreign communications systems and noncommunications emitters, the broad category that covers both is SIGINT. It encompasses both communications and noncommunications signals, making it the most comprehensive and appropriate answer.
