Whoever kills civilian first = civilians become their enemies for remainder of game

[jpinard 10]

I'm setting up a dynamic scenario of Russians vs. US. The civilians start out netural (armed), but whoever is the first to accidenally cause a civilian casualty will then have to fight the civilans as well. The trick here in the scenario is there is a lot of "area of effect" weaponry, but they'd better be darn sure there's no a civilian in sight before targeting an area.

So how would I do this?

Thank you! :)
