It's all been said. However, stepping away from the main theme, I'd love to have more civilians and not just Maquis or fleeing people with wooden carts, but modern citizens from different countries as well. One thing about modern war as opposed to the wars of centuries past is that the fighting very much takes place under the noses of civilians. That's not a pretty thought but there you have it - give us the stuff to show that.
Although I'd hate to see the modelling police come around to tell me that flared pants were not worn until 1968 so you're WRONG...
