AI artillery use

[Imp]

Just a thought
Realise the AI sometimes sets artillery as reinforcements so they are available later in the game & it occurred to me this might be further refined for attack assault battles possibly when its defending to.
If it sets some as reinforcements to enter on turn 2-3 it will not waste them firing blind as it should have an idea of some enemy positions by then. Mainly applies to big stuff or CM as even if the pre plotted stuff hits there can be a few turns gap till in range. This is more important on maps 100 plus wide perhaps it could base it on map width.
Really good possibly would be to combine with leting the scouts go while rest delay a few turns as sometimes happens.
I only say this because the AIs arty routines are generally very good but it tends to use its expensive CM stuff rockets etc before it sees any targets.
The other options if easier is to make the AI use them like mine dropping artillery in those type of battles (i.e. not available at outset) or just not call the CM for a few turns so it could still fire smoke & HE if available.
That said I think this would work in WWII to reserving a few big guns as covering ground is slower.
The other possible benefit is it could concentrate fire as the new batteries are targeted at the few available targets.
My gut feeling is this could spring a few nasty surprises.
