What is the approximate length and width for a Final Protective Fire using 4 tubes of 120mm Mortars?

The appropriate dimensions for a Final Protective Fire (FPF) using 4 tubes of 120mm mortars reflect the effective area that can be covered to support ground troops. FPF is designed to provide immediate indirect fire support to protect friendly forces from enemy advances. In this context, the length typically ranges between 300 meters, allowing for substantial coverage across the designated engagement area, while the width is more focused and strategic, often noted around 75 meters.

This specific combination maximizes the distribution of the mortar fire while ensuring that the coverage is both broad enough to affect the target area effectively and narrow enough to minimize the risk of collateral damage to friendly forces. Thus, selecting dimensions of 300 meters in length and 75 meters in width for the FPF establishes an effective balance of coverage and safety in combat operations.
