Hmm, okay, I'll admit I was thinking primarily of the 100 Years' War.
Clearly we have to give the rules the benefit of the doubt at this point (and I'm going to wait a while, having only just got around to ordering Sword and Spear).
BTW, purely a guess, but D seems likely to stand for discipline, though that may be a bit too similar to cohesion to be a worthwhile distinction when there are only two categories.
I'm also wondering why another attempt to replace Warhammer Ancients is needed, when we already have Scarab Miniatures' War and Conquest, which was supposed to be a 'thinking man's WAB', or something of the sort, as well as Great Escape Games' Clash of Empires. Neither appears to have gained much traction.
(Confession: I own both, but have played neither).
