Name three intelligence disciplines and a brief example of each.

• A. HUMINT (human intelligence), SIGINT (signals intelligence), IMINT (imagery intelligence)
• B. HUMINT, GEOINT, MASINT
• C. ISR, CMO, OPORD
• D. LOGISTICS, SUSTAINMENT, INTEROPERABILITY

Answer: (A)

Understanding how intelligence is gathered from different sources helps you pick the best trio. The strongest three are HUMINT, SIGINT, and IMINT. HUMINT gathers information from people—like debriefing a source or interviewing someone with relevant knowledge. SIGINT covers intercepting and analyzing signals, such as radio or electronic communications, to extract actionable details. IMINT uses imagery from satellites or aircraft to observe physical features, movements, or changes on the ground, such as spotting a facility under construction or tracking convoy activity.

Other options mix in related concepts or non-intelligence terms, so they don’t fit as a clean set of three disciplines with clear examples.
