The Net-centricity and Global Information Grid (GIG) visions enable systems to be interconnected to support multilateral, civilian and military missions. The constantly changing environment requires the commanders to plan for missions that allow for units from various nations, agencies etc. to join or separate from the team, depending on the situation, as the mission unfolds. The uncertainty of the actual mission and that the potential for agencies and organizations to support the mission after it is underway, leads to a vast number of potential scenarios that civil and military personnel need to train in individual and collaborative training environments.

It is not feasible to train for every possible mission and every possible combination of teams. The Next Generation Training Systems need to manage this complex and dynamic environment. The simulation support needs to be unified such that training performed at home stations and in mission training/mission rehearsal that may occur just days, hours or even minutes before the actual missions are as interoperable as possible. It is becoming more important to adapt to the latest doctrine of the adversary. This need to adapt coupled with the specific intended concept of the operation must drive the civil and military agencies, organizations, and units selected for the mission at hand. The need for rapid mission rehearsal capabilities drives the requirement to transform to simulation infrastructure that includes interoperability mechanisms that enable a more agile, dynamic and adaptive interconnection of heterogeneous simulations.

In this paper a step towards the Next Generation Training Systems is presented. The concepts, ongoing research and standards are described and the role of the Coalition Battle Management Language as one of the key enablers for the Next Generation Training Systems is presented. Methods and tools used in demonstrations to show fast integration between heterogeneous Live, Virtual and Constructive simulations with Command and Control Systems are exemplified.
