e. The final protective fire (Figure 2-7) is an immediately available prearranged
barrier of fire designed to impede enemy movement across defensive lines or areas. It is
integrated with the maneuver commander's defensive plans. The shape and pattern of FPF
may be varied to suit the tactical situation. The maneuver commander is responsible for
the precise location of FPF. The FIST chief is responsible for reporting the desired
location of the FPF to the supporting FDC. Authority to call for the FPF is vested in the
maneuver commander (normally, the company commander or platoon leader) in whose
area the FPF is located. The FPF is represented on a map or firing chart by a linear plot.
The length of the plot depends on the type of unit assigned to fire the FPF. The
designation of the unit that will fire the FPF is placed above the plot representing the
FPF.
