The Digital BattleStaff Sustainment Trainer (DBST) is a live/virtual/constructive simulation federation developed to meet the U.S. Army's digitized command and staff training requirements. Its roots extend back to the Fire Support Simulation Tools (FSST) and the Synthetic Theater of War - Architecture (STOW-A) programs. The DBST federation primarily uses Distributed Interactive Simulations (DIS) protocols for simulation interoperability, but has often used High Level Architecture (HLA)/DIS gateways to interoperate with BLA federate simulations. DBST has been used by the U.S. Army world-wide, to include the Division Capstone Exercise (DCX Phase I) at the National Training Center (NTC), the Joint Contingency Force - Advanced Warfighting Experiment (JCF-AWE) at the Joint Readiness Training Center, the Interim (Stryker) Brigade Warfighter Exercise at Fort Lewis, Washington, several brigade rotation exercises at the NTC, theater-level counter fire exercises by Eighth U.S. Army in the Republic of Korea, numerous combined operations by the Third U.S. Army, Central Command, and several digital training events in United States Army, Europe (USAREUR). DBST was selected as the Army's primary simulation (federation) for Millennium Challenge '02, and was highly successful in interacting within the Joint Experimentation Federation and meeting the Army's experiment objectives. The DBST federation is fully interactive, and through the use of interface systems, is able to provide digital feeds to the training audience Command, Control, Communication, Computer & Intelligence (C4I) systems regardless of whether the original source systems are live, virtual or in constructive simulation. DBST is able to federate with simulated Unmanned Aerial Vehicle (UAV) and other collection assets to provide UAV video to the command post and Joint Surveillance Targeting Acquisition Radar System (JSTARS) workstation feeds to Common Ground Stations (CGS). With linkage to live instrumented forces through systems such as the Combined Tactical Engagement Simulation System (CTESS) and the Deployable Instrumentation Training System (DLTS), DBST is able to provide a seamless Synthetic Training Environment for command and staff training. Recently, USAREUR used DBST to support V Corps (Victory Corps) Victory Strike III exercise in Poland, with an emphasis on deep strike operations planning and execution. This paper describes the Victor Strike III DBST architecture and how it continues to prove its use in meeting the Army's training needs.
