arma3epoch player assignment

[[email protected]]

Players can only log in as civilians on my epoch server... it came this way by default. I am unsure how to change this to either all blufor or a selection of all three factions..? civilians cannot use UAV .... I have looked in the mission.sqm and i seen some stuff in there that looked like it might be it but I don't want to break anything. Does anyone know how to either set it as a selection or change all to blufor? I have done alot of searches and found nothing useful enough to inspire faith. 

THANKS
