Tough it is geared towards large-scale violence - bombing, artillery, WMDs, starvation - where you have problem discriminating the violence.

Well, there was a large number of "internally displaced people" fleeing from Slavonia and Krajina, either from the areas forming the RSK or from the frontline areas still held by Croatia. But part of this might have been just part of the "general mobilization" in the Autumn of 1991.

Similarly, in the days preceding Operation Storm in 1995, the authorities of the RSK initiated a mandatory evacuation of the civilian population, resulting in a wave of refugees into Bosnia.

Now, in both cases a large part of the flow of refugees/internally displaced is an "evacuation towards the rearguard" rather than being driven out at gunpoint, but the distinction is not very useful. The flow of refugees is the same and the cause of the flow is the general condition of fighting.
