Apply established modeling approaches, experiment designs, and analytic methods while contributing recommendations for improvement.
Instantiate combat system, platform, and behavior models in the simulation environment.
Instantiate kill chains, battle management command and control relationships, and other scenario-specific mission and operational factors in the simulation environment.
Support the development and instantiation of an experiment design in the simulation environment.
