When all weapons are fired at maximum rate to stop an enemy assault, what is this referred to?

The term that describes the action of firing all weapons at maximum rate to stop an enemy assault is "Final Protective Fire." This concept is crucial in military operations as it refers to pre-arranged and coordinated fire designed to deny the enemy access to a critical area or to halt their advance effectively.

Final Protective Fire is typically employed when a command recognizes that an enemy assault is imminent and requires an immediate and decisive response. It ensures that every available weapon system is utilized to create a barrier of fire that the enemy cannot cross, providing crucial support for friendly forces and maintaining the integrity of defensive positions.

In contrast, the other terms don't specifically denote the same level of urgency or coordinated mass firing aimed explicitly at halting an enemy assault. Final Resisting Action might suggest a broader strategic approach or engagement but lacks the specific definition tied to concentrated fire. Concentrated Fire Control typically refers to the management of fire from various units rather than an all-out effort to stop an assault. Lastly, All-Out Defensive Fire could hint at a robust defense, but it does not accurately capture the coordinated, maximum-effort response implied by the term "Final Protective Fire."
