Under what circumstance would you use the "Unobserved" spotting?

The use of "Unobserved" spotting is applicable when the round's impact is known, but it is not directly observed by the fire support team or observer. This typically occurs in scenarios where the observer cannot see the actual impact point due to factors such as terrain, obstacles, or distance, yet they have received confirmation or intelligence indicating that the round landed in a specific area. It allows the observer to continue directing fire without having a visual confirmation, relying instead on reports or other data regarding the impact location.

This method is essential for maintaining the effectiveness of fire support operations, especially in complex environments where visibility may be limited. Using unobserved spotting effectively requires the observer to have confidence in the information they have received or deduced about the target and the round's performance. It plays a critical role in coordination and ensures that the intended target can still be engaged even when visual confirmation is not possible.
