SIGNT in intelligence terminology refers to which type of intelligence?

• A. Signal intelligence, involving interception of radio signals.
• B. Open Source Intelligence from public websites.
• C. Covert espionage intelligence gathered in the field.
• D. Social media sentiment intelligence.

Answer: (A)

The concept being tested is how intelligence categories are defined by their information sources. SIGNT stands for Signals Intelligence, which involves intercepting and analyzing signals such as radio communications, radar emissions, and other electronic transmissions to extract information. This is distinct from Open Source Intelligence, which uses publicly available information; from Human Intelligence, gathered covertly through people on the ground; and from social media data, which falls under OSINT or modern data sources but isn’t the SIGINT domain. Therefore, the best answer is the one describing the interception of radio signals as signal intelligence.
