What additional information is sent along with the warning order in the first transmission of the naval surface fire support (NSFS) call for fire?

The additional information that is sent along with the warning order in the first transmission of the naval surface fire support (NSFS) call for fire is the target number. The target number plays a critical role in coordinating and directing fire support effectively. It provides a unique identifier for the target, which helps in avoiding confusion during operations and ensures that the intended target is engaged.

The inclusion of the target number in the first transmission allows the fire support team to efficiently manage and allocate fire assets to the specified target. This identification is crucial for maintaining operational clarity and ensuring that all units are synchronized during fire missions.

While other pieces of information such as the method of control or description are important in subsequent transmissions to fully delineate the mission requirements, the target number is essential in the initial communication to pinpoint which target requires firing.
