Winter Duel is an official skirmish map from Supreme Commander. Winter Duel is the smallest official map in Supreme Commander. It has a rectangular size of 5km by 2km. Tactical missiles and T2 artillery installations are able to hit the whole map as it is small. That's if the game lasts long enough to get one up. Defensive warfare is completely nonexistant. The closest thing one can come to stalemate to is the constant buulding of armies and ending up in a draw after a fight in the middle. Otherwise, Tech 1 rushes tend to end the game pretty quickly unless there is a very long anti-rush timer.
