Variable Strategy Ratings?
If you were fielding a force with two detachments, and those two detachments were from separate armies with different Strategy Ratings, how would you work that situation out?
Would you make all strategy rolls using the lowest of the two ratings, or would you have each detachment roll separately? Or something else?
As a secondary question, are there any rules against fielding a two-detachment force made up of separate armies? The rulebook says it's fine to field two (or more detachments), but doesn't really say whether it's okay if they're from separate armies. I assume it is (and anything goes, with permission, in friendly games, obviously), but just asking out of interest.
