I guarantee you that setup is wrong. 100%.
When we get to the battle board, Larry says you have to have at least one infantry survive as the last unit, even if it means taking other units as casualties. Got that. But does this mean that you cannot have stacks in land areas which contain no infantry?
Does it mean that, for example, you could not station aircraft in a rear area without infantry present, because they wouldn’t be able to fight if attacked?
He didn’t say that yet but it makes sense. I bet you need one infantry to claim even income ( sort of a garrison rule)
Also says that infantry of a friendly power do not count - does this mean that friendly units can fight in an attack, or just when defending?
Turns are separate, so only in defense they roll together.
For example, the “Alsace-Lorraine” area is contested between 5 French and 5 German units. The British move 5 units in to attack the Germans. Do we assume that the French units sit in their trenches holding their own sector of the front, and cannot participate or be taken as casualties? If so, the reference in the battle board description is curious.
If that happens it has not been established how that works based on the current information.
