First post - no flames.

I want to make a mission similar to the one (Choice, was it?) in OFP: Resistance, where the protagonist had to make a choice between fighting for the Resistance, becoming an informer and trying to remain out of the action.
I want to make the player Civilian an enemy of the East side.The problem is that as Civilians are neutral to all sides, the Russians won't fire at the player apart from "forced" fire (
dotarget and
fire). How can I change this and make my mission actually playable?
There is no need for an actual switch of sides during the mission, it is enough if I can make it so that the Russians recognize the character as an enemy from the start.
