Just stating my opinion on it. If I have to ask something or make a suggestion, then:
What island are you using? Personally Everon or Nogova would give the best results (if you're using default game islands). Everon because it can be split right down the middle into north and south near Tyrone. Nogova because of two things:
Same reason as Everon only east and west. Right down the river.
If you noticed, Nogova has eastern style architecture (concrete prefabs) on one side and western style buildings on the other. This creates the perfect atmosphere for a communist vs. capitalist war.
And of course, an obvious reason being that it is the best island, since it has large cities and quaint country sides, plus Resistance objects. If you don't have Resistance, then go with Everon.
Anyway, I always felt the setting is an important part of a mission. That's my two cents on it.
Sorry, bedges. I'll remember to include a suggestion next time.
