I just finished an operation based on the 82nd Airborne's defense of Grand Halleux. I spent so much time on the map that I wanted to use it for a battle of a theoretical counterattack. But I can't figure out how. The map seems to be nested in my original operation with no hope of retrieval. This is contrary to other programs (Close Combat, Steel Panthers). Any ideas?

I'm working on a historical scenario in which the Americans blew the bridge with pre-set charges before the Germans could cross. How can this be done with demo charges. I tried and the engineers fire small arms at he bridge, but refuse to use their demo charges. There are so many historical scenarios that need this function. Thanks
