Say, you're a Russian demolitions expert in WWII and you've rigged a bridge to blow up when a set national socialist van (that carries them weapons) crosses it. Out of the corner of your eye you see a national socialist barge, and when you look closer you see a mortifying sight: lots of prisoners with a few national socialist machinegunners protecting them. As they go under the bridge said national socialist van approaches the same bridge.
If you blow the briidge it will all collapse in on the barge and wreck everyone inside. If you don't you miss the van AND you disobey the orders. One of the two generals sees the scary cosequences and is against the blow. The other had his family decomissioned by a national socialist firing range and is all for blowing the bridge.
What do you do?
