What is an immediately available prearranged barrier of fire designed to impede enemy movement?

The concept of an immediately available prearranged barrier of fire designed to impede enemy movement is specifically represented by Final Protective Fires (FPF). FPF is utilized to create a last line of defense to slow or stop enemy forces from advancing toward friendly positions. This type of fire is typically pre-planned and positioned at locations where enemy movement is anticipated, ensuring rapid execution when the situation demands it.

The effectiveness of FPF lies in its ability to be coordinated before enemy contact, allowing for a quick response to threats. This prearrangement ensures that troops are prepared and able to engage effectively when they need to protect their positions. Additionally, the FPF encompasses a specific artillery or mortar response that guarantees coverage over critical areas, making it a vital component in fire support planning.

Understanding the role of FPF aids in comprehending fire support tactics, as it is critical for maintaining the integrity of defensive positions and provides a clear indication of how firepower can be leveraged to shape the battlefield.
