The traditionally structured military planning process, and supporting toolsets, is largely based upon the traditional two-sided force-on-force actions that are paced by a timing cycle based upon the maneuver unit's echelon level. As we have seen in recent events, this paradigm has largely proven to be obsolete along several lines. First and foremost is the dynamic nature of current operations. Sensors, targets, and resources now present themselves in very narrow windows of availability. Second is the multidimensional nature of the applied force. Strategic forces can now extend down to an individual aircraft or squad, and the planning and replanning cycle is now measured in minutes versus days. Collectively, the increase in possible courses of action (COA) and the reduced planning/replanning time frames create a dramatic need for a tool to assist the mission planer. This is creating a new opportunity for modeling and simulation to become an integrated element of the overall operational command and control structure. This model is constantly updated using real-time information feeds to provide an ongoing assessment as to the viability of the current COA and possible alternatives. In this paper, we will address such a planning system; one that makes use of integrated modeling and simulation to gain insight into possible outcomes and to manage the possible futures. This paper will also contain the rational, structure, and implications of such a system.
