What command is used to cease all fire during a call for fire?

The command used to cease all fire during a call for fire is "Checkfire." This term is specifically employed to instruct all firing units to stop firing immediately, ensuring that no further rounds are launched toward the targeted area. "Checkfire" carries significant urgency and implies that the safety of personnel or civilians in the vicinity may be at risk due to potential friendly fire or changing battlefield conditions.

Understanding the context of its use is crucial, as it is recognized across military communications as the standard term for halting fire. This ensures clarity and prevents misunderstandings that could arise with other commands. Other terms such as "Cancel," "Halt," and "Stop" may not convey the same level of urgency or may have differing connotations in military jargon, which could lead to confusion in critical situations. Hence, "Checkfire" is the standard command for ensuring that all units cease firing promptly and effectively.
