In the C2 context, which best describes the differences among surveillance, reconnaissance, and intelligence?

• A. Surveillance observes activity to detect events, reconnaissance collects data to answer specific questions, intelligence synthesizes analysis to inform decisions.
• B. Surveillance and intelligence are the same; reconnaissance is unrelated.
• C. Surveillance is used for weather; reconnaissance for medical data; intelligence is irrelevant.
• D. Surveillance only gets direct enemy contact; reconnaissance only collects photos.

Answer: (A)

In this C2 context, the differences among surveillance, reconnaissance, and intelligence come down to purpose and output. Surveillance is broad, ongoing observation aimed at detecting events or changes in the environment. It looks for patterns, anomalies, or signs that something notable is happening, often over time and across a wide scope. Reconnaissance is more focused and purposeful data gathering designed to answer specific questions or to fill particular knowledge gaps needed for planning or action. It targets particular areas, assets, or capabilities to produce data that can be used to make a targeted assessment. Intelligence is the synthesis of what has been observed and gathered, analyzed, and interpreted to produce actionable insights that inform decisions. It combines context, reliability assessments, trends, and potential implications so leaders can decide what to do next. In practice, surveillance provides the situational awareness, reconnaissance supplies the exact facts to address defined questions, and intelligence delivers the recommended actions or decisions based on those inputs.
