The fires function and targeting process continues to mature at an accelerated pace as joint, coalition, and supporting forces remain engaged in on-going, high-tempo operations. These continuing operations reinforce the need for knowledgeable and efficient planners, targeteers, and weaponeers. Emerging technologies and joint warfighter experiences combine to turn lessons learned into improved and new joint fires and targeting planning, execution, and assessment best practices. Many of these innovative procedures are recognized by the joint community, but they are not yet approved joint doctrine. This handbook was developed to ensure commonly accepted best practices for planning, executing, and assessing joint fires and targeting are documented. While this handbook does contain extracts from many doctrinal publications, it is not approved joint doctrine, but serves as an important pre-doctrinal product that will aid its refinement. United States Joint Forces Command developed this handbook for combatant commanders, subordinate joint force commanders, joint force staff members, and first tactical echelon personnel.
