ABSTRACT: NATO established the Allied Command for Transformation (ACT) to be able to effectively and efficiently meet its new and existing military requirements. Modelling and Simulation (M&S) will be used as an enabling technology as well as an enabling methodology to support the transformation of the NATO forces. The NATO Modelling and Simulation Group (NMSG) Conference (MSG-028) "Modelling & Simulation to support NATO's New and Existing Military Requirements" was conducted in Koblenz, Germany from 7 to 8 October 2004. All sessions of the Conference were unclassified. The conference addressed organizational and technical aspects of this increasing challenge, and provided hints of applicable technologies to deal with crowd modelling, terrorists' activities and urban operations. The keynote speeches and papers presented covered NATO, national and Partnership for Peace efforts. The results contained in these conference proceedings will help to define future Research & Development domains and provides an overview of the contribution capability of the participating nations and organizations.
