Add a type of faction thing that is something like a Russian PMC that could play for either side or against either side. They would obviously announce it and put it in their name or something like that. It would be a cool thing.
This is an interesting idea. We will most likely have event jobs from other factions like Russia, China, Taliban, ISIS, etc. However the idea of having a whole other faction with it's own ranks and structure is a whole other topic. I sort of like the idea but definitely need more talks about it.
