JCATS is a discrete event, constructive simulation that simulates actions and events of people and systems in specified environments. Its interactive design enables operators to initiate and influence events, although outcomes are stochastically determined utilizing user-defined statistical data. JCATS simulates the “effects” of actions and events to simulate combat at the entity level.

JCATS is data-driven, which enables users to rapidly define and refine their scenario parameters to ensure realistic simulation of their specific scenario.
