I'm finally getting around to giving WIA the play time it deserves, and I find that I just don't understand certain things about leaders.
I'm coming from AACW and NCP, where leaders are attached to brigades, formed into divisions, made to lead Corps, and appointed to Army command in ways that make perfect and coherent sense to me. In WIA, however, it seems that leaders are piled together with combat units such that, effectively, every WIA stack is just one big unit (in AACW terms). There are some cases where leaders are merged with brigades (as with those Germans and their pet battalions), but these are rare.
Is it ever possible to merge a leader with a unit in WIA? I can't find the usual interface cues for this, and I have read the manual thoroughly. If leaders don't merge, here's my big question: do all leaders' special abilities apply to all combat units in the same stack? For instance, does a leader with the "skirmisher" trait give that ability to every unit?
Also, stack size: Is there an upper limit to the size of a stack in WIA? In AACW stacks are ultimately constrained by a cap on command points, but that cap does not seem present in WIA.
Thanks for answers!
