How many meters is the range correction rounded off to?

The range correction in a Call for Fire (CFF) context is typically rounded to the nearest 100 meters. This standard is used to simplify communication and ensure clarity when providing adjustments during artillery fire. Rounding to 100 meters helps to streamline the process and minimizes the potential for error, especially in high-pressure situations where quick and accurate adjustments are critical.

In practice, this means that if a range correction is calculated to be, for example, 345 meters, it would be rounded to 300 meters for the sake of commanding the artillery strike. This method of rounding helps maintain both efficiency and effectiveness in fire support operations. The other choices, while they represent potential increments of range corrections, do not align with the standard approach of rounding off to the nearest 100 meters in CFF procedures.
