During the EA DEV step, what is necessary to determine to achieve the desired end state?

In the Engage Area Development (EA DEV) step of military planning, determining the number of weapon systems available is crucial for achieving the desired end state. This is because the effectiveness of any engagement heavily relies on having a sufficient quantity and variety of weapon systems to match the anticipated enemy forces and the required tactical outcomes.

The number of weapon systems influences the ability to effectively execute firepower and maneuver options during operations. A well-planned engagement area incorporates the right balance of heavy, maneuver, and support elements within the available forces. By understanding how many weapon systems are on hand, military planners can establish a realistic approach to channel enemy forces into kill zones, optimize fire support coordination, and ensure the units can sustain operations effectively.

While understanding the location of enemy forces, type of terrain, and support force capabilities are all important factors in EA DEV, they do not address the direct tactical execution elements as thoroughly as knowing the number of weapon systems. The latter directly impacts the planning for firepower application and mission success in achieving operational goals.
