What is the approximate length and width in meters for an FPF fired with 4 tubes of 120mm Mortars?

The selected answer reflects the standard dimensions for a Final Protective Fire (FPF) involving a firing unit of 120mm mortars. An FPF is designed to provide a rapid volume of fire to protect friendly forces from enemy forces and is typically established in situations where a quick response is necessary.

For an FPF fired with four tubes of 120mm mortars, the approximate length is around 300 meters. This length allows for the effective coverage of the designated area, often reflecting the tactical needs of the operation. The width of 75 meters is considered sufficient to ensure the density and effectiveness of the fire while minimizing the risk of fratricide and collateral damage, as mortars can have a significant spread.

This specific combination of length and width aligns with established firing data and doctrine that guides mortar units in providing effective fire support. Understanding these dimensions is essential for planning and executing fire missions, ensuring that the coverage is adequate to deter or destroy enemy forces in close proximity to friendly troops.

In contrast to the other choices, they do not adhere to the typical established parameters for an FPF with this particular mortar system, making them less suitable for operational planning within the context of the scenario.
