Appendix B B-2 FM 3-09 30 April 2020 B-3. A dashed black line, with "CFL" followed by the establishing HQ above the line and the effective date- time group below the line provides graphic portrayal of the CFL (see figure B-1). Locations for CFLs are disseminated by message or overlay through maneuver and fire support channels to higher, lower, adjacent maneuver, and supporting units. Figure B-1. Coordinated fire line example FIRE SUPPORT COORDINATION LINE B-4. A fire support coordination line is a fire support coordination measure established by the land or amphibious force commander to support common objectives within an area of operation, beyond which all fires must be coordinated with affected commanders prior to engagement, and short of the line, all fires must be coordinated with the establishing commander prior to engagement (JP 3-09). B-5. FSCLs facilitate the expeditious attack of surface targets of opportunity beyond the coordinating measure. The FSCL is not a boundary-the synchronization of operations on either side of the FSCL is the responsibility of the establishing commander, out to the limits of the land or amphibious force boundary. The FSCL applies to all fires of air, land, and sea-based weapon systems using any type of ammunition. The JFLCC and JFMCC cannot employ fires long of the FSCL without coordination with affected commanders, and the JFACC cannot employ fires short of the FSCL without coordination with the JFLCC or JFMCC. Supporting elements attacking targets beyond the FSCL must ensure that the attack will not produce adverse effects on, or to the rear of, the line. The appropriate land or amphibious force commander controls all air- to- ground and surface-to-surface attack operations short of a FSCL. The FSCL should follow well-defined terrain features to assist identification of the air. Coordination of attacks beyond the FSCL is especially critical to commanders of air, land, and SOF (JP 3-09).
