I was playing a game yesterday and we encountered a situation where all the infantry units were bought and a village was attacked. What should be done in this case? Take 2 of either artillery or mounted?
Since we were playing with both expansions we solved it by taking a unit from basic deck and using it's stat for the attack value. But I'm sure that isn't the way to do it.
Thats a rare situation. Normally some units are dead in battles. I think the rules are that there will be no infantry unit to take, thus only using 2 units. But I think at that point in your game, the units are pretty strong, so it wouldn't have mattered anyways.
