Observer Special Missions 28 September 2017 ATP 3-09.30 7-5 If adjusting the FPF, the initial target location sent is not the location of the center of the FPF but a grid that is a safe distance (400 to 600 meters depending on the weapon system) from friendly troops. Encode the grid or send it by secure means because it is part of a final defensive plan. Instead of a target description, announce FINAL PROTECTIVE FIRES. Announce ATTITUDE and DANGER CLOSE (if applicable) in method of engagement. 7-20. Fuze delay reduces the danger area from fragmentation. Adjusting with fuze delay minimizes the safety hazard to friendly units. 7-21. The firing unit will fire a battery or platoon (mortar platoon) right (or left) one volley at a five second interval, or as specified by SOP, centered on the initial grid sent by the observer. For example, assume that the rounds impact as shown in figure 7-4. The observer begins the adjustment with the flank piece impacting closest to the FPF line (in this case, number 1). Creeping fire adjustment procedures must be used in danger close situations. The observer adjusts the round to within 50 meters, sends refinement and announces the piece is adjusted. For example, NUMBER 1, RIGHT 20, DROP 25, NUMBER 1 IS ADJUSTED. Figure 7-4. Adjustment of the FPF begins with the flank piece round closest to the FPF line (number 1) 7-22. Once the first gun is adjusted, the observer sends NUMBER 2, REPEAT and adjusts each weapon in succession.
