If you are at 30L and the target distance is 2600m, what is the correction?

To determine the correct correction for a given target distance using the Call for Fire (CFF) format, it is crucial to understand how the distance affects the adjustment needed. The target distance here is 2600 meters, and you are currently at a reference point of 30L (which indicates a grid coordinate).

In artillery and fire support operations, corrections are often based on established tables or guidelines that indicate how much deviation is necessary for a specific distance. The mention of 'R' in the answers suggests that these are range corrections for the fire direction, indicating either an increase or decrease in the distance to adjust the fire accurately.

At 2600 meters, a correction of R90 is appropriate and indicates that the rounds should be adjusted to impact 90 meters to the right. This is likely because positioning the target somewhere in the field based on your current coordinates requires a rightward adjustment within the established parameters for that range.

The other options (R100, R80, R70) represent alternative adjustments that would not align with the standard adjustments calculated for a target at 2600m. Correct calculations based on target distance, firing position, and proper table usage are crucial in determining the precision needed in artillery adjustments, and in this case, R
