The Distributed Mission Training (DMT) program links high fidelity cockpit simulators and crewmember workstations over a wide-area network into a single virtual battlespace. Simulators in the DMT system have been procured from different vendors and are largely designed to provide the best possible team training for that crew. Achieving interoperability among these disparate simulators and support items is the primary challenge for the DMT Operations and Integration (O&I) contractor.

The key to achieving effective interoperability in the DMT environment is the integration of constructive and virtual simulations and models through the use of a common battlespace content and a consistent set of data protocols. It depends upon a common data model for the battlespace that covers the full scope of required inter-team training simulation content, in a manner that can be implemented in a variety of ways for different federations and mission types. The DMT Master Conceptual Model (MCM) provides the description of the shared battlespace necessary for team training interactions.

The MCM is a set of products that together define a battlespace or virtual world at a level of abstraction suitable for defining training objectives, guiding implementation, and identifying limitations to inter-team training scope. It provides the conceptual framework for DMT battlespace entities and interactions, and guides the development of the standards and the DMT Portal software. The data model of the battlespace provides the common semantic content in the form of entities, events, interactions, and phenomena along with the parameters that describe them.
