Providing a comprehensive planning and decision support framework appropriate to today's complex operational environments requires a shift from the traditional approach of single-scope, military wargaming. To fully capture the operational environment requires the representation of a multi-sided political, military, economic, societal, information, and infrastructure (PMESII) framework that can be integrated to support course of action (COA) development for Wargaming, Mission Rehearsal and analysis. This integration must be across diverse domains, span local to global scopes, and allow for excursions over different time durations and geographical regions. Such an integrated adaptive planning environment is a many-sided approach allows a user to plan the actions of any entity in the environment and at any scope.

The core simulation technology described herein consists of the Synthetic Environments for Analysis and Simulation (SEAS --- an agent-based model), and the Integrated Gaming System (IGS --- the DoD Adaptive Planning and COA analysis tool), linked together in a Society of Systems (SoS) that integrates the heterogeneous simulations into a single experimentation environment.

This paper describes how a multidisciplinary team developed this integrated planning and experimentation framework using the SoS approach. Further, it describes the employment of this framework to support the training objectives of both the USMC Command and Staff College's Nine Innings Exercise and the U.S. Army War College's Strategic Decision Making Exercise, two wargaming environments intended to provide current and future decision makers an appreciation of the utility of PMESII Modeling and Simulation as a key element of the planning process.
