the most oppressed minority

I googled a bit (admittedly without much heart) and I didn't find any active sim groups that play as anything but war crimin- I mean NATO. So this leads to me asking here if any of you know of any active groups for mostly Arma 3 who focus on playing operations as the opposing forces to NATO? If not, would there be interest in forming such a group among us? It doesn't have to be big, my dream isn't full 60 count servers but a basic crew of maybe 4 to 8 people that can play occasionally would be lovely.
