Which of the following is NOT a use of fire control orders?

Fire control orders are essential commands used to coordinate and manage the use of weapons systems effectively. They help ensure that the use of fires is executed safely and efficiently while minimizing the risk to friendly forces and non-combatants.

When considering the functions of fire control orders, they primarily focus on coordinating and directing the application of firepower, particularly from indirect fire assets like artillery, air support, and missile systems. For instance, direct artillery fire and clearance for missile strikes are direct applications of fire control orders, as they specifically involve directing the use of these weapons in combat situations. Additionally, initiating air-to-air combat may also require coordination, although it can be less formal than ground-based fire missions.

In contrast, authorizing ground troop movements does not typically fall under the category of fire control orders. While ground troop movements may require briefings and the awareness of fire control measures to ensure safety, they are usually planned and directed through operational orders or maneuver control rather than fire control orders. Fire control orders primarily deal with the engagement and application of weaponry rather than the movement of troops. Thus, the correct identification of the option that does not align with the primary purpose of fire control orders is accurate.
