What brevity term is used when marking a target by infrared (IR) pointer?

The brevity term "sparkle" is used when marking a target with an infrared (IR) pointer. This terminology is part of the standard communication protocols utilized in joint fire support operations, where clarity and quick understanding are crucial for coordination among various units.

Using "sparkle" indicates that the operator is directing an IR laser towards a target to provide identification and marking for friendly forces, particularly for precision-guided munitions. This method enhances accuracy and reduces the risk of fratricide, as it directly informs aircraft and other support elements where to focus their efforts.

The other terms, while related to targeting and designation, do not specifically refer to the action of marking a target with an IR pointer. Understanding this specificity in terminology is essential for effective communication in a fast-paced operational environment.
