The planning size (width and depth) of a Final Protective Fire for a 105mm 6 gun battery is what dimensions?

The correct dimensions for the planning size of a Final Protective Fire (FPF) for a 105mm 6 gun battery are 210 meters in width and 35 meters in depth. This specification is based on standard artillery practices, ensuring that the FPF effectively covers a designated area to provide a robust defensive fire capability.

These dimensions are based on the operational effectiveness of the battery, taking into account the radius of effective fire from the 105mm rounds and aiming to maximize coverage while minimizing the risk of causing harm to friendly forces. The width and depth are determined to ensure that any attacking force entering the designated area would be met with an overwhelming volume of fire, thereby serving as an effective deterrent and protective measure for friendly troops.

Selecting this specific size allows for comprehensive engagement of threats while maintaining operational safety for allied units. The other choices do not align with established military doctrine for planning FPFs for this type of artillery system, as they either exceed the required coverage dimensions or fall short of standard engagement parameters.
