At what time is a unit required to notify Range Control upon discovery of a missing individual?

The requirement to notify Range Control immediately upon the discovery of a missing individual is crucial for safety and operational efficacy on the range. This immediacy ensures that a rapid response can be initiated, which is vital for locating the individual as quickly as possible.

Timely notification minimizes the risks associated with having someone unaccounted for in a potentially hazardous environment, where ranges may be used for live-fire exercises or other dangerous activities. It allows Range Control to implement search and rescue protocols without delay, which can significantly increase the chances of a positive outcome.

In contrast, options suggesting a delay, such as notifying whenever convenient or by the end of the day, compromise safety. Delayed notification can lead to increased danger for the missing individual and hinder effective search efforts. Thus, immediate action is not just a procedural necessity but a critical component of risk management and readiness in military operations.
