What is the defense rating against buildings for?

I have never noticed buildings shooting back on a land unit or air units. Let alone ships.

So why is there a defense rating against buildings?

Its not really in use. Until we may implement some unit one day which has the building armor class (e.g. coastal gun? ).

I was thinking more like giving industry some inherent AA-value. So in effect a lvl 3 industry would fire back some more than a lvl 1.

Not heavy AA, mind you. Just a small value to make off-line players less vulnerable and to add to the overall AA during bombing raids.

Wasn't the point that a defending unit would slightly damage enemy buildings while defending on a province node?
