One Semi-Automated Force (OneSAF)
Print Friendly, PDF & Email


One Semi-Automated Force (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, enhanced 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.

OneSAF was created to be uniquely capable of simulating aspects of the urban operating environment and its effects on simulated activities and behaviors. OneSAF is unique in its ability to model unit behaviors from fire team to company level for all units in both combat and noncombat operations. Intelligent, doctrinally correct behaviors and a range of constructive, gaming and virtually based user interfaces are provided to increase the span of control for workstation operators.


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