:

Built-in support for DIS (Distributed Interactive Simulation) and HLA (High-Level Architecture) for networked combat training.

The build natively supports DIS protocols. This capability enables real-time, joint-forces training exercises across different geographical locations. Multiple simulators representing aircraft, ground vehicles, and maritime vessels can interact within the exact same virtual airspace.
