For an FPF fired with 4 tubes of 120mm Mortars, what is the approximate length and width?

In a Fire Support Team (FIST) context, the Fire Plan Formation (FPF) is a designated area for artillery or mortar fire that is calculated based on the number of tubes firing and their capabilities. For a scenario involving four tubes of 120mm mortars, the dimensions of the FPF are determined by the effective area coverage and dispersion pattern of the mortars.

The standard approach for calculating the dimensions involves understanding the blast radius and the effective range of the munitions being used. With 120mm mortars, you can expect a width around 75 meters and a length of approximately 300 meters when firing in a designated area intended to engage a target effectively. This takes into account the dispersion pattern of fire from multiple tubes when they are employed simultaneously.

The dimension of 300 meters in length allows for sufficient coverage of the target area, ensuring that the rounds impact effectively across the designated zone, while the width of 75 meters provides a suitable engagement area, maximizing the impact and damage to the target.

This reasoning aligns with the tactical use of mortars in field operations, emphasizing the need for effective dispersion and coverage when coordinating indirect fire support in conjunction with ground troops. Therefore, the correct dimensions for the FPF fired with
