One Semi-Automated Forces (OneSAF) reduces duplication of Army Modeling and Simulation (M&S) and other government agencies’ investments, fosters interoperability and reuse across M&S communities, and meets the M&S requirements of the future force.


To satisfy all U.S. Army M&S community and other government agencies’ needs for a common, reusable, computer-generated (ground) forces entity-level simulation.


OneSAF is a computer-generated forces simulation that provides entity-level models and behaviors that are both semi-automated and fully automated applications designed to achieve Army readiness. As a cross-domain simulation, OneSAF supports the training, test and evaluation, analysis, intelligence, acquisition and experimentation communities by providing the latest physics-based modeling and data collection, and reporting capabilities. OneSAF models real-world representations of platforms, Soldiers, equipment, logistical supplies, communications systems and networks, emerging threats, and aviation assets to achieve the level of fidelity required for a particular application or scenario.

Benefit to the Warfighter

OneSAF eliminates the need for multiple simulation tools across analysis, experimentation, test and evaluation, training, intelligence, and acquisition modeling and simulation communities and provides a transparent training environment for today’s commanders and their battle staffs by utilizing current Mission Command Systems.
