My Brigade (3d BCT, 10th Mountain Division) recently started using OFP with add-ons funded by the Defense Advanced Research Projects Agency (DARPA) - now called Ambush!. DARPA actually conducted a comparison of 6 gaming engines with potential uses for military training a couple of years ago and OFP came out on top by far. We are in the process of deployment to Afghanistan and will attempt to use it as a mission rehearsal tool. Next week I will attend a military gaming conference where we will discuss what other game engines are out there and hopefully put resources behind one instead of the 4-5 that are being used to some extent right now. As of right now, OFP-Ambush is as good as it gets mainly because of its intuitive mission editor, which is essential to rehearsing missions.
