What is the outcome of not acting on a target detected in time?

The outcome of not acting on a target detected in time is best described as a "Missed Target." In the context of fire support operations, when a target is identified but not engaged promptly, it represents a tactical opportunity that has been lost. The failure to act can result in the target escaping or being neutralized by enemy forces, which diminishes the effectiveness of the fire support mission.

"Target of Opportunity" refers to a target that is detected unexpectedly and engaged immediately, rather than one that was previously identified and then not acted upon. A "Declared Target" is a target that has been formally recognized and assigned for engagement, while a "Referential Target" typically signifies a target that is referenced for potential engagement but may not be actively pursued.

In summary, acting swiftly on identified targets is crucial within fire support operations, and delaying that action leads to the situation labeled as a "Missed Target."
