Chapter 7 7-6 ATP 3-09.30 28 September 2017 Example The weapons firing are a 105-mm battery (six guns in this case). The supported commander shows the observer where to place the FPF. The observer sends the following call for fire: H12 THIS IS H18, ADJUST FIRE, OVER. GRID NK123456 ALTITUDE 105. FINAL PROTECTIVE FIRE, ATTITUDE 1900, DANGER CLOSE, DELAY, OVER. The battery fires a battery one round. The sheaf is shown in figure 7-5. The observer notes that howitzer number 6 impacted closest to the FPF line, and begins the adjustment with it: DIRECTION 0810, NUMBER 6, LEFT 100, DROP 50, OVER. The round is fired and the observer believes that the round is within 50 meters, and sends a correction (the round is not fired) and calls for number 5 to fire: NUMBER 6, DROP 25, NUMBER 6 IS ADJUSTED. NUMBER 5, REPEAT, OVER. 7-23. Adjust the other weapons as previously discussed. Figure 7-5. Adjustment of the FPF begins with the flank piece round closest to the FPF line (number 6) AUTOMATED FDC 7-24. The observer adjusts only the center weapon onto the center grid of the FPF when adjusting for an automated FDC that uses muzzle velocity variations and special corrections. NON-ADJUSTED FPFS 7-25. In some instances, the tactical situation dictates against adjusting the FPF. In these cases, give the dimensions of the FPF in the call for fire. The locations can be sent using: Grids to the two endpoints. The center grid and attitude. Length, width, and attitude. Laser draw. (see para 7-33)
