OOBs need a full rebalance... first see non arty regiments in non german units is... (is a lot better leave arty in a regiment and reinforce infantry regiments with AT rifles, maybe 5 76mm and MGs like in DC1) ...
I am not sure what you mean by this.
Most (if not all) WW2 combatants had two, really three, sorts of Artillery ...
1) Divisional Artillery - mostly Howitzers and Gun Howitzers which were intended primarily for long range indirect fire (that is, map or spotted fire at targets the guns couldn't actually see). These are, I am presuming on the most cursory of glances, the tubes that are in the Divisional Artillery Regiments for the Germans (I haven't had a look at the Russians or Axis allies *at all*). They were under the Division Commander's control and used as he saw fit to support the Division's operations.
2) Infantry Guns - so called because they were part of the TO&E of the Infantry units (Battalions, Regiments, whatever). These were generally direct fire weapons with limited indirect fire ranges. They were intended to operate in direct support of the Infantry Regiment?Battalion they belonged to. Often (mostly) Guns rather than Howitzers. They were under the Regimental or Battalion Commander's control and used as they saw fit to support the Battalion/Regiment's operations.
3) Mortars - most were part of the TO&E of Infantry units (Battalions, Regiments) and used in support of Battalion/Regimental Ops by the Battalion/Regimental Commander. Some were deployed down at Company level and under the control of the Company commander. In a few cases, some lighter models may have been deployed at Squad level.
DCCB does, afaict, a reasonable job of modelling this three way split ... in other words, the artillery in the Infantry (or Armour or Mechanised or Motor) Brigades are from (2) and (3), not from (1), which is as it should be.
Isn't this the same in axis allied and Russian units? Is that what you are getting at? If so, then, yes, I agree, it really needs to be changed.
