When is the range element of a fire command mandatory?

The range element of a fire command is mandatory when the Laser Range Finder (LRF) is not available or is nonoperational. This requirement ensures that the forces involved have accurate information on the distance to the target, which is crucial for effective engagement. Without the LRF, the commander must provide an alternate method of determining range, such as estimating or using other visual cues, to ensure that the weapons system can be employed accurately.

In scenarios where the LRF is operational, the range can often be given directly by the device, but its absence necessitates more careful attention to ensure the engagement remains effective and safe. This highlights the importance of reliable range information in direct fire engagements, as it affects accuracy and the success of the mission.

Other scenarios presented, such as engaging at close range, target movement, or firing at long-range targets, do not have a mandatory requirement for the range element as they can sometimes be effectively estimated or calculated based on other available data or tools. Thus, the specific need for a clear range command is linked directly to the operational status of the LRF.
