Final answer:
Direction is stated with the Grid Mission in artillery after determining the target's range. Hence, the correct answer is option (b).
Step-by-step explanation:
In artillery, direction is typically stated after determining the target's range. Once the range to the target is known, the artillery operator can adjust the elevation and azimuth (direction) of the artillery piece accordingly.
First, the observer identifies the target and determines its range. Once the range is established, the observer communicates this information to the Fire Direction Center (FDC). Afterward, the observer provides the direction, specifying the azimuth or grid coordinates. This sequential approach ensures a methodical and accurate transmission of information, allowing the artillery unit to effectively and precisely target the identified location.
Coordinating the range before direction helps streamline the communication process and enhances the overall accuracy of artillery fire.
