What is the default method of control for fires in a Call for Fire?

The correct answer is "Fire when ready." This method of control indicates that once the forward observer has coordinated and confirmed the target information with the supporting unit, they can execute the fire mission as soon as the unit is prepared to do so. This approach allows for a rapid response to targets, which is crucial in dynamic combat situations.

Using "Fire when ready" enables greater flexibility and responsiveness, especially in situations where timing is essential for effectiveness against enemy targets. It also communicates a sense of urgency, allowing artillery or supporting fire to be delivered without unnecessary delays.

In contrast, "Hold fire" instructs units to refrain from firing, which is counterproductive when immediate action is required. "Fire on my command" implies that the observer is controlling the timing of when to fire, which can lead to delays compared to the default method. Lastly, "Cease fire" completely interrupts any ongoing fire, which is not applicable in the context of a Call for Fire when the aim is to engage the target effectively and promptly.
