What is a planned target determined using deliberate targeting and triggered upon detection?

The correct choice describes a target that is identified beforehand through deliberate targeting processes, which involves careful planning and coordination. An on-call target is not considered a target that is fired upon schedule or during a predetermined time frame; rather, it is a target that can be engaged as soon as it is detected, allowing for greater flexibility in response to changing battle conditions.

In contrast, a scheduled target is one that is predetermined to be engaged at a specific time. Deliberate targets are identified in advance but do not necessarily rely on detection to trigger the attack, as they are part of a planned operation. Dynamic targets are those that emerge unexpectedly during an operation and are engaged based on real-time intelligence and immediate tactical needs.

By understanding these distinctions, one can see why "on-call target" is the term that best fits the definition of a planned target that is activated upon detection, making it the correct answer.
