What is a required component of the call for fire that identifies the type of adjustment?

The call for fire requires a component that specifies how the observer intends to adjust artillery fire on the target, and this is encapsulated in the warning order. The warning order provides initial instructions regarding the type of fire to be delivered, the method of adjustment, and other critical information needed for clarity and effectiveness in communication. By including the method of adjustment, this component ensures that the supporting artillery or fire support elements understand how to respond based on the specific situation and requirements of the mission.

In the context of fire support, the warning order serves as a proactive communication tool that guides the subsequent actions of the fire support team and coordinating units, allowing for a more synchronized and effective response to the situation on the ground.
