Modeling and Simulation Coordination Office
The Defense Modeling and Simulation Office is "the catalyst organization for Department of Defense modeling and simulation and ensures that modeling and simulation technology development is consistent with other related initiatives."
In late 2007 the DMSO was renamed the Modeling and Simulation Coordination Office (M&S CO).
The M&S CO leads DoD M&S standardization efforts, is the DoD point of contact for coordinating M&S activities with NATO and Partnership for Peace (PfP) organizations, and provides support to the DoD M&S management system.
