For Excalibur calls for fire, to what minimum grid locations should they be expressed?

For Excalibur calls for fire, the minimum grid locations should be expressed in 10-digit format. This level of precision is necessary to ensure accurate targeting of munitions, as Excalibur rounds are precision-guided artillery shells designed for accurate engagement of targets.

Using a 10-digit grid coordinate allows for a higher degree of specificity in locating targets, ensuring that the impact point aligns closely with the intended target area. The additional digits provide a finer granularity that is critical when coordinating fire in combat situations, especially when civilian infrastructure or friendly forces may be in proximity to the target, thus minimizing the risk of collateral damage.

While lesser digit formats, such as 6, 8, or even 12 digits, have their own uses in different contexts, the need for precision in Excalibur engagements necessitates the use of at least 10 digits to adequately meet the operational requirements of the mission. This specificity helps facilitate effective communication between the fire support team and artillery units, ensuring the desired outcomes in complex combat scenarios.
