Overrunning art/HQ?

[ulver]

Could someone clarify exactly how the overrunning of art and HQ works now?

[hjaco]

They die [:D]

Yes I get that but:

Will Art alone being overrun be destroyed 100% of the time?
HQ?

How about art stacked with cavalry?

Stacked with Infantry that is eliminated due to combat results?

Basically what it comes down to is if they're alone in a hex with enemy combat units, they're eliminated 100% of the time. Which prevents artillery units being used as a "skirmish line" falling back in the face of the enemy.
