Which statement best defines surveillance?

• A. Random sampling of soil.
• B. Systematic observation of aerospace, surface, subsurface areas and personnel by visual, electronic, photographic, or other means.
• C. A method of mass casualty triage.
• D. A form of encryption.

Answer: (B)

Surveillance means systematically watching and gathering information about a space and the people within it over time, using tools like visual observation, electronic monitoring, photography, or other means. It covers areas above ground, on the surface, and below, as well as the personnel present, and it’s framed as ongoing, purposeful monitoring to detect activity or potential threats. This makes it the best fit because it describes a structured approach to observing environments and people, rather than actions focused on other tasks like sampling soil, triaging casualties, or encrypting data.
