At the National Training Center, brigade combat teams (BCTs) have a difficult time establishing, maintaining, and transitioning a permissive fires environment at echelon within the decisive action training environment to shape the BCT deep fight and mass effects in the close fight in support of tactical and operational objectives. This handbook provides the fires community a way to plan, prepare, and execute its mission to establish, maintain, and transition a permissive fires environment at echelon to shape the battlefield. It also provides commanders and their staff with insights on the capabilities and employment of fires.
