The Modeling and Simulation Coordination Office (M&SCO) directly assists and supports the Under Secretary of Defense for Acquisition, Technology, and Logistics (USD(AT&L)) and the Modeling and Simulation Steering Committee (M&S SC) in executing DoD M&S Enterprise responsibilities assigned in DoDD 5000.59. To accomplish this, M&SCO provides support, as shown in the diagram below, in three key areas:

1. Governance: enterprise-level coordination among the M&S activities of the DoD Communities and Components to encourage cooperation, synergy, and cost -effectiveness;
2. Operations: which includes sustainment and operation of enterprise level capabilities - tools, data, and services - that support USD(AT&L) and the M&S SC in the management and execution of DoD M&S Enterprise activities; and
3. Technical Collaboration: a technical forum to advise and influence the DoD Enterprise on issues involving M&S.
