What is typically required from the observer before executing a fire mission in CFF?

Before executing a fire mission in Call for Fire (CFF), it is crucial for the observer to confirm the target's safety and clearance. This step ensures that there are no friendly forces or civilian structures within the danger zone of the intended target area, thereby reducing the risk of collateral damage and friendly fire incidents.

The observer must make an assessment of the situation and communicate with relevant parties to ensure that the proposed strike will not compromise safety. This involves confirming that there are no friendly troops, civilians, or critical infrastructure at risk in the area affected by the incoming fire. By prioritizing safety and clearance, the observer plays a vital role in the overall effectiveness and responsible execution of a fire mission.

The other options, while related to aspects of military operations, do not directly pertain to the immediate responsibility of the observer before a fire mission. For instance, obtaining permission from all supporting units or coordinating with the ground commander can be part of a larger operational procedure but does not take precedence over the safety considerations that must be addressed first.
