This report describes the technical platform used by the command and control warfare simulator (C2WS). The C2WS uses HLA for distributed simulations and a lot of models are included by reuse of results given from other R&D projects. The C2WS consists of three parts, one for scenario planning and configuration, where models are configured, one for dynamic duels, and finally one assessment module, where the duels can be replayed and logged data analyzed.
