So lets say you have a mountain region. You have a legion or two and some of those archers and skirmishers with the added ability of bonus in wooded hill, alpine or mountain terrain.
Approaching you is a way superiour army, leaderwise and numberwise.
However they have to attack into a mountain area.
How would you as the defender setup up your forces? In one stack, or split it up so that one leader controls the skirmishers and one controls the legion you have?
Would you use the "ambush" function on the skirmishers?
Or would none of this matter so its best to just put everything in a big stack?
Let me know your thoughts.
