More than 20 years ago, I wrote networking portions of such simulations. Even for the unclassified components for those simulations, many of the components were still both commercial secrets and considered munitions under ITAR export controls.

Terrain maps beyond a certain resolution are classified. As I remember, the somewhat lower resolution terrain maps were still ITAR controlled munitions. Some of the radio propagation models are classified.

Even half-way decent simulation outputs are likely also classified.

In my case, for the most part, the simulations were used to shorten the turnaround time in the early prototyping stages, and also a fair amount for the sales team to sell military hardware to governments.
