In a Division that has units split in editor (so not by the split button in game) how does it handle TOE upgrades? i mean how does it knows that the Artillery regiment gets only army weapons(artillery) instead of infantry, is it by the type of subunit? but how for not so clear cases like Infantry guns that can be considered army weapon?
Typically a Division is made up of three regiments + additional combat engineers, AA and Artillery. Perhaps a few tanks/armoured cars as well.
If the Regiments have already been formed into Brigades, they already have some of the additional heavy gear in the Division TOE, so combining three Brigades does not usually leave the division with many more devices lacking to complete the TOE. However, three bare Regiments combined have few heavy weapons so when they combine the Divisional TOE in effect is applied and the AI gets demand for the missing devices (unless you set Replacements Off).
So the TOE (which is just a list of what the unit is entitled to have) is not associated with those units until they combine. There are no devices in a TOE, only in a unit that is using the TOE to draw the devices.
After combining units into a division, if you split them again you get three A/B/C pieces of the division (called Regimental Combat Teams in the US) which get 1/3 of the TOE each, with the A portion getting any left over numbers not divisible by three. There is no separate TOE for the divided division. Also note that the original units that were combined to form the division are gone - they will not show up after splitting the division again.
So for your Arty unit not yet combined into a division, it will have its own Arty TOE and that is it. No infantry required.
