There are multiple vendors, but the big one that I am aware of is called KORA. It was used in planning the counter-attack in Ukraine and you can find numerous references to it, such as in this [1] article. But this and classical war-gaming and very related. The entire point of war-gaming (beyond training) is to try to predict the outcome of a conflict.
