Though that would also mean that AT and AA will die faster when they are attacked WITH infantry support in the same hex and I don't know if I would find that much better...
I don't know, does it mean that?
I've looked at the description of combat in the rules and it does not indicate one way or another. And, if damage is done by the strength of the constituent elements within a unit, then, as noted elsewhere, the Artillery elements are probably far too strong.
If you are correct it would be a problem, to some degree. Perhaps a great degree.
Of course, it would encourage the correct use of artillery ... behind the front lines, supporting the infantry and armour, rather than *in* the front lines (that's for the Infantry Guns and the like in the actual Infantry Regiments or Armour Regiments).
The problem is, at this scale, that the artillery *should* be deployable in the same hex, given that it's what, 20-25 klicks across? At that scale, the artillery would be still behind the lines, nominally. Even if it's a 10-15 klick hex (it doesn't actually seem to say in the manual anywhere, anyone know hex size?), the artillery would still nominally be behind the infantry.
Given the scale, having the divisional artillery a hex behind the division would be unrealistic, though it would work.
I dunno, perhaps infantry/armour regiments in the same hex could take a larger proportion of any damage inflicted unless/until they are broken/retreat and leave the artillery in the same hex "uncovered"?
I don't know whether any of this could be done within the system or, more importantly, could be done *easily* within the system ... so it may all be problematic.
Another option would be to reduce the "dig in" rate and maximum entrenchment value achievable by artillery units outside of fortifications and, perhaps, towns and cities ... but that would be suboptimal, I suspect.
Lots of possible solutions and ten times as many possible problems
