AI Artillery Spotting

[Green]

Did you notice if the units were actually shown as being Spotted?

It is possible that they have been spotted by Air Recon. Or depending on the scenario you are playing there may be Dust Spotting. If you are using the Indirect Fire and Air Strikes By The Map optional rule, then any hex in range is valid whether Spotted or not. I assume it was definitely artillery and not air support?

I cannot think of anything else off-hand but there is bound to be a good explanation. I know next to nothing about the AI but have never heard that it breaks the rules in any way and would be surprised if it did.
