3-13. Close coordination is required to integrate airspace use with the employment of fires. Fire support agencies normally establish FSCMs. Integration and deconfliction of airspace and joint fires normally occurs during mission planning where FSCMs, ACMs, and other appropriate coordination measures are disseminated through command, airspace control, air and missile defense, and fire support channels. Real-time coordination, integration, and deconfliction of airspace and joint fires with airspace control elements and C2 nodes are essential in developing situations. For more information on fire support coordination and FSCMs, see FM 3-09.
