What must the observer specify in the target location portion of an Excalibur call for fire?

In the context of an Excalibur call for fire, the observer must specify the Target Location Error (TLE) in the target location portion. This is critical because the Excalibur munition is a precision-guided artillery shell that relies on accurate targeting to maximize its effectiveness. The TLE provides a measure of how far the observed target location may deviate from the actual target, which helps ensure that the munitions are correctly guided to the intended point.

The TLE is essential for maintaining operational effectiveness and minimizing collateral damage during artillery strikes. By providing this information, the observer assists in the precision employment of the munitions, which aligns with the capabilities of the Excalibur system, aimed at precision strikes.

The other options, while they may relate to military operations or target assessment, do not specifically pertain to what needs to be included in an Excalibur call for fire regarding target location. Thus, specifying the TLE is necessary to ensure clarity and accuracy in the fire support process.
