4) AI artillery routine fires at first valid target. Then it adjusts!

While it is uncertain what the initial valid target happens to be this much is certain... given above preferential treatment to anything the AI sees as the "A0" target. While designing set pre-fire targets... set those targets at least N-1 turns!

The AI will fire upon the A0 if it doesn't have anything to target, B0, C0, D0, etc are also acceptable. It will do this even in the face of 50 other units that it can see and ignoring FOs which have better artillery abilities.

If you drop pre-fire artillery around the map the AI will adjust it as possible. Preferentially, toward the A0 unit but then toward anything close enough.
