Guerilla RTS games

[spydert767]

iv always wanted to find a game where you can act as a Guerilla force, especially in an RTS style, but i cant find one anywhere, the closest iv found is arma but thats not really what iv been looking for, if anyone knows any game like this id love to check it out (p.s my pc is kinda ass so please dont reconmend games with insane visuals)
