Which term is used to describe the observer in surveillance, often referred to as the "eye"?

• A. Surveillant
• B. Eyeball
• C. Coded Radio Communications
• D. Planning Surveillance Steps

Answer: (B)

The observer in surveillance is described as the eyeball because this term captures the direct, real-time visual input at the heart of the activity. The person acting as the eyeball is the one who literally sees the target, notes details, and relays what’s observed to the team, making them the immediate “eye” of the operation. This emphasis on live sight and reporting distinguishes the eyeball from broader terms like surveillant, which can refer to watchers in a more general sense, or from items that are about tools or steps (coded radio communications and planning surveillance steps) rather than the person who looks. So, eyeball is the best fit because it conveys the essential role of the human observer providing the visual feed that drives the surveillance effort.
