Before a control correction during immediate suppression, what must you send?

To initiate a control correction during immediate suppression, it's crucial to provide the target description. This information allows the receiving unit to accurately understand which target is being addressed and ensures that subsequent adjustments or corrections can be made effectively. By clearly communicating the target description, you help maintain situational awareness and precision in artillery operations, which is essential in high-stress, rapid-response scenarios typical of immediate suppression missions.

Reliable engagement depends on everyone involved knowing precisely what target is under consideration; vague or unclear information could lead to misfires or ineffective fire support. The other choices, while relevant to different aspects of fire control, do not specifically encompass the immediate need for clear identification of the target in the context of a control correction.
