What must be added to the fire command when engaging multiple targets?

When engaging multiple targets, it is essential to add a modifier to the fire command. A modifier serves to differentiate between the various targets and provides clarity to the fire direction personnel. This ensures that the correct fire control measures are followed for each target, allowing for an organized and effective engagement while preventing confusion that could lead to friendly fire incidents or miscommunication.

Modifiers can include designations such as "Target 1," "Target 2," and so forth, or additional information about the targets like their type, distance, or priority. By including this information, crews and personnel involved in the engagement can act precisely and efficiently, aligning their efforts according to the established priorities and tactical needs of the operation.

Modifiers play a crucial role in modern combat scenarios, where multiple threats may need to be addressed simultaneously, and the speed and accuracy of such commands can significantly affect the outcome of engagements.
