I have been putting support units in Army HQs because I assumed that Engineers, Doctors, Balloonists, Signalers and Marines contributed their special talents to All UNITS (corps) commanded by the Army HQ, even if they are NOT stacked with the Army HQ, and not just the HQ itself.
However, I think now that these support units are only supplying their talents to units that are in the same "stack" with the Army HQ -- is this the purpose of the "option" to have all subordinate corps end thier turn in the same region as the Army HQ?
Clarification please! Whom do support units in an Army HQ affect with their special abilities?
thanks,
