What term is used when all weapons are fired at maximum capacity to prevent an enemy assault?

The term "Final Protective Fire" refers specifically to a type of defensive artillery or weapon response intended to halt or disrupt an enemy assault. This tactical maneuver involves delivering a concentrated volume of firepower at maximum capacity, ensuring that the enemy is deterred from advancing. This strategy is used as a last resort to protect friendly forces and positions, typically employed in a defensive scenario where the threat of an imminent enemy attack is present.

In a military context, the "Final Protective Fire" is not just about firing weapons at their maximum rate but is a coordinated and deliberate action meant to create a heavily fortified barrier against enemy forces. This distinguishes it from other terms like "Rapid Fire Response" or "Maximum Fire Rate," which do not capture the strategic intent and context of the action.
