What brevity term means to mark a target by using an infrared (IR) pointer?

The brevity term that means to mark a target using an infrared (IR) pointer is "Sparkle." This term is commonly used in military operations to indicate that a target has been visually marked or illuminated for identification. When a ground unit uses an IR pointer, it helps air support or other units identify the exact location of the target, especially in low-visibility conditions, without giving away their position to the enemy.

This method of target marking is crucial for coordinating strikes and ensuring that friendly forces can effectively engage the designated target without risk to themselves or nearby allies. The use of IR pointers and the term "Sparkle" facilitate precise and secure communication between ground troops and air support, enhancing operational effectiveness and safety during combat missions.
