Surveil is defined as which of the following?

• A. The initial acquisition of a radar contact.
• B. Systematic observation of airspace by electronic, visual, or other means.
• C. The evaluation of engagement effectiveness after completion.
• D. The process of aligning weapons with the target.

Answer: (D)

Surveil in this context is about maintaining continuous observation and tracking of a potential target so the fire-control system always has up-to-date data on where the target is and how it’s moving. That sustained observation provides the information needed to move from simply knowing where the target is to actually pointing the weapon where it needs to be to engage it. In other words, surveillance supplies the essential input that leads to aligning the weapons with the target—the step where aim lines up with the target so a firing solution can be executed. The other options describe different parts of the process: initial contact is just the first moment of detection, evaluation after engagement is about after-action assessment, and aligning weapons with the target is the action that follows from having accurate surveillance data.
