APPROVED FOR PUBLIC RELEASE

The conference theme, M&S Support to Transitioning Forces, speaks to the need to grow better capabilities for the future while sustaining the lessons learned from past deployments. One such better capability now growing under the auspices of the NMSG is MSG-085 "Standardization for C2-Simulation Interoperation" which is leading the way to new capability where coalition partners can simply “plug in ” their command and control (C2) and simulation systems on a common network and thereby exchange the information needed for simulation-based training, mission rehearsal, and course of action analysis. Using such a capability, every group would “train as you fight, ” using their own national C2 system and would be represented by their own simulation. This paper reports on significant steps forward in C2-simulation interoperation that have been developed and implemented by the authors in support of MSG-085: a coalition of simulation, C2, and web-enabled infrastructure systems that are capable of interoperating over a variety of syntactically different schemata, to the extent they are semantically compatible. Further, the system provides support for distributed, interoperating servers. This system enables interoperation among coalition partners who may be working with simulation and C2 systems developed with different schemata generations or versions. It also support
