How is surveillance distinct from reconnaissance?

• A. Surveillance is passive and continuous, layered with technical systems
• B. Surveillance is active and overt
• C. They are identical
• D. Recon is passive and continuous

Answer: (A)

The idea here is how surveillance operates versus reconnaissance. Surveillance is about ongoing, passive monitoring of an area, activity, or people, typically supported by multiple technical sensors and systems layered together to provide continuous data over time. That combination—being passive, persistent, and tech-enabled—is what sets surveillance apart.

Reconnaissance, on the other hand, is an information-gathering mission that is usually active and targeted, often involving direct observation, movement, or probing to obtain specific details.

So the best answer reflects surveillance as passive and continuous, integrated with technical systems that layer observations over time. The other options either suggest surveillance is active or ordinary, claim the two are identical, or assign passive traits to reconnaissance, which doesn’t fit the distinctions between these two methods.
