26 October 2021 ATP 3-09.12 B-1 Appendix B Friendly Fire Log This appendix discusses the secondary mission of the WLR which is to support friendly fire elements. It also provides an example of the radar friendly fire log and instructions for filling it out. FRIENDLY MISSION B-1. Friendly fire missions are missions that are fired to conduct weapons registration with nonstandard conditions, or to validate firing tables and calculations for existing conditions. This includes actual burst datum plane and predicted impact location data. B-2. The AN/TPQ-36 performs this mission only when the commander deems it absolutely necessary. The reason is that the secondary mission takes the AN/TPQ-36 away from its primary mission of locating hostile weapons. In addition, it exposes the WLR location to hostile EW systems. Because the AN/TPQ-36 WLRs cannot radiate in friendly fire mode and hostile fire mode at the same time, the commander must issue specific guidance as to when and how friendly fire mode will be used. This determination is made based on METT- TC, availability of observers, and the ability of the supported unit to meet the requirements for accurate fire. B-3. The AN/TPQ-53 WLR can perform hostile and friendly missions simultaneously. The AN/TPQ-50 does not perform friendly missions. Effective use of zones and prior coordination with the FDC may be used to separate hostile from friendly acquisitions. FRIENDLY FIRE LOG B-4. The radar operator uses DA Form 5310 (Radar Friendly Fire Log) to record all the pertinent data for any type of friendly fire mission. The form is designed to be completed with input from the fire direction center. DA Form 5310 should be used anytime a friendly fire mission is sent by voice, digital, or when printer is not operational. See figure B-1 for an example DA Form 5310 on page B-2.
