Reviving my old cold war other life...
so read, trials and mistakes, and played...overall a very good game, but quite a number of questions appeared, some maybe as a bloody foreigner might who have missed some niceties of the godon language (yes I also play medieval)
Like other people elsewhere, pardon me, but I think the artillery deviation rule is rubbish. It might be valid for 1-1 play if we assume the "turn" is a few minutes at best, and allows for ranging shots...I explained my grumbling and mod are on my site:

Then I had a pb with the on table Sp122 bn of my soviet rgt. I used it as off table arty but then found out I should not. Fine but...
it says bn guns (modern?) are by roughly 3 (mortars too 3/4? then Brit bn has two?)
so my 18 tubes should be 6 vehicles on the table?
should they all fire on the same target?
Can they be activated by hq to shoot directed by different callers (effectively the unit targeting via the HQ) at the same time? if not, hardly they will fire much.
If an off board 6 tubes has a 10 cm front fire zone (dispersed sheaf) then on table "one target" is concentrated, possibly (and simpler) warranting the same dice.
And don't believe modern mortars and arty will shoot much, if at all, with themselves sighting the target (that is, against a peer enemy). SP122 soviet in urban or vs entrenched inf, maybe, though we see nowadays their failures.

You can use the SAU-122 off table. Lists also allow you to attactch all three batteries to one of your rgt btns. Only that btn can fire it, but you use the Btn HQ CV to callthe guns.

Ian is correct - you can use any off-table SP-Art on-table or vice-versa.

I know I can use it off table, that's even what I did
But if not?
1 model for 3 tubes or one for 6?
How do I fire them? can I have 6 different targets in the same activation? then the hit dice should be lower.
I would allow only one target per "caller" but still all 6 or one per battery (probably more real) with the same hit dice as off table. The system of using the Hq as a "controller" means in the case of the RU rgt that the arty major is co located with the rgt hq.
With my 9 km deep table I would have a lot of the arty on table. Or on table off table make everything work the same...

TBF I am confused by your question. Are you looking to convert an OOB into actual models?

Typically, I'd purchase a battery of 3 artillery units/models (for all guns under 200mm in calibre).
So in a typical Soviet MRR (for example) I have 3 x SAU 122s attached to the MRR - 1 to each BMP/BTR formation, and under the command of that formations HQ.
I typically convert a Soviet MRR on-table into:
1 x CHO + Recce, (you can add the 3 attached regimental SP-ATGW to the CHQ)
3 x 9 BMP/BTRs + 3 x 1 x ASU122 (on-table) +  2 x 1 x ZSU 23-4 and 3 HQs + 3 recce,
plus 1 HQ + 9 MBTs + 1 ZSU-23-4 (or equivalent) + tank recce;
and 3 x 2 batteries of ASU 155s off-table and 2 x MRLs. with an FAO commanding them on-table.
Plus all the infantry and support weapons in the BMPs/BTRs

If you elect that these are off-table guns, they are either allocated to pre-set target (assuming you have bought the appropriate asset(s) to deliver this type of fire) or are attached to an on-table  FAO (or in the case of Soviets can be attached to an HQ).

Each (off-table) gun fires once per game turn - either as pre-set Assets or under commanded fire.
Guns can be ordered as a battery - so all 3 guns fire at the same target point - or can be fired/ordered individually.

If firing the guns off-table the FAO (or HQ) nominates the target and the number of guns involved and then follows the procedure on page 52-56 in the book. If off-table the batteries can be ordered separately if they are firing at different targets - so you need a successful command roll for each gun in turn.

If the guns are on-table - a single order can be used to fire any number of guns in a single turn, and each can target a separate enemy unit (as long as those units are all visible to the Command unit commanding the fire). These on-table guns can also be ordered repeatedly to fire (at the same or different targets) in multiple turns, as long as their Commander passes a successful command roll.

Off-table guns use templated. On-table guns only target specific individual units.

Does any of that help you?

Yes very much!
I would use infantry companies with only mostly 2 veh. + inf and their platoons are very small -(company with 10 Bmp vs Nato commonly 13-15) dismounted element at best 21 men x3. plus 1-2 with mmg- spigot etc.per bn.

Spassiba, sio karacho.

If you choose to have your ASU 122s off table - you would have more of them - so I have 3 off-table for each 1 that I would have had one table.
That is because the off-table guns only fire once per game-turn.

Enjoy

I get the impression the OP is asking that because his table is very large, can the batteries that are normally off-table in a standard game actually be on table, some 4-10km to the rear, but use the off-table artillery rules?
The obvious answer is yes, because that reflects reality - it's whether any rules adjustments are needed. And you'd have to know the actual range of the weapons fielded to ensure they are in range of the battlefield, which isn't difficult to find out.

In a game that big, armoured breakthroughs, air assaults or air attacks could bring those "off-table" assets directly under fire, and the artillery battalion would then become an activating unit of it's own accord.
So if the appropriate artillery Bttn or Regiment HQ is fielded with any integral defence units, as models, around those guns, they could then carry out direct fire in self-defence, or more likely limber up and bugger off. Which is why historically all Soviet artillery carried some anti-tank shells, as they learned in WW2 that your indirect fire artillery assets can suddenly become direct fire assets.

Western armies not so much, as the M109 for example has no direct fire anti-tank round. Although all gunners are trained for direct fire just in case with HE.
I do recall an unusual example in WW2 in Normandy where Canadian Sextons were engaged in direct fire with opposing Wespes, both of which carried ~6 anti-tank rounds, and in the 1973 war Israeli M107s had to engage tanks direct fire at one point. In another IDF example, one of their M7 Priest battalions was shot up by direct fire on the Golan.

Food for thought.
