Then there are those 15 cm infantry guns - pure nastiness! However, historically there tended to be only two per infantry regiment.

15cm things have too few ammo to make an impact(especially if you only have 1 or 2) and having ammo carriers around for them would be the path to overkill...
I try to avoid having anything other than company mortars in my core, if i'm battalion sized, i get some AT and extra mortar for core units, but most arty(and some ATG) comes in as support...
