Possibility to add new faction?

I love your mods and all that go with it, but maybe if you know how we could add a Gurilla faction that resembles the Asian Congo soldiers from the last Rambo or a Vietnam group if that works, i'd love to see what you can think up.

Video that I think helps protray what I mean : https://www.youtube.com/watch?v=qc1g-W9Kgds&feature=related

I can, maybe.

I will see how it goes now when school's started.
