Soviet Medium/Heavy SU Brigade [OB:2122, OB:2123]

[Wiedrock]

Those two were opposed to the Light SU Brigade, formed out of full 3 Regiments as it seems.

For the Infantry, Niehorster lists them as having a Company of 79Men per Regiment with 9LMGs, this would give 8Men Squads with 7SMG+1LMG (so should eventually all be SMG Squad (+)) [which currently has 11Men ].

Medium

In December 1944, the formation of three medium self-propelled artillery brigades of the RVGK began, consisting of three SU-100 regiments, each with the numbers 010/500, 010/462, 010/526, 010/527, 010/504 — 010/506, 010/ 514 of 1944 (1492 people, 65 SU-100 and 3 SU-76).

Heavy

On March 1, 1945, the 143rd separate tank Nevelsk brigade in the Belarusian-Lithuanian military district was reorganized into the 66th Guards Nevelsk heavy self-propelled artillery brigade ISU-122 RVGK (staff No. 010/516 - 1804 people, 65 ISU-122 and 3 SU-76). The organization of this brigade was completely similar to the brigade organization SU-100. The 66th Guards Brigade was the only heavy self-propelled artillery brigade in the Red Army. Until the end of the war she acted as part of the 70th Army 2nd Belorussian Front.

Attached is how the numbers may change the Composition. Making historically correct smaller Squad sizes [at least 9, not 11] would change the numbers again.

Edit: This Source does not mention the AT-Rifles at all, http://tankfront.ru/ussr/organisation/010/461_sap.html removed AT-Rifle from calculations since those somehow only can be found at Niehorster...
...maybe they were intended separate Attached AT units? ....weird.

The Regiments seem to have contained 18x AT-Rifles each (those AT Rifles are also missing in the 1944 Light/Medium/Heavy SU Regiments currently in game). It is possible that there was at one point an order removing them from the TOEs, in other occasions AT-Rifle Squads were disbanded to get the Manpower to man the tanks in other units, that may be the case here too - not sure. But all I see (so far) is they were there in the TOEs.

As with the Light SU Brigade, nothing set in stone. If someone ahs further/clarifying info, appreciated.
As opposed to the light SU brigade these two were built from 3 regular Regiments + further parts, at least this seems "clear".
TL:DR: only manpower and Infantry Squads changed.



Manpower:
What should definitely be wrong right now is the manpowe (according to all info I could find).
The difference between the two 1492 vs 1804 manpower comes from the heavy Regiment having ~100men more → x3 gives ~300men difference (at least the Regiment TOE numbers I have at hand (not being Niehorster's numbers from 04 and 08/1944)). Otherwise both brigade types were exactlythe same.

Squads:
When it comes to the "SMG Squads" I only have Niehorster giving some more info with 79men, then there is the possibility of the 101men "SMG Company" being meant (which includes HMGs (without them its ~90Men)), I can't say for sure. All the different "SMG/Machine Gunners"-namings and different translations makes it easy to lose specifics in translation for me.
Niehorster lists a BA-64 and many more men as part of the Regimental Scout/Recon Platoon (but he also gives dates from April/August 1944 - I suppose further ammendments were made to the Regimental TOEs (altough he lists 5x4SUs settings while the actual setting shoudl have been 4x5SUs (?) ..... )) - if it is/was rly applied to all three types of Regiments, then those Scout squads are missing (at least for the ~mid 44 amendments to the Regiments he may be citing - which would in return impact the Brigade's composition as well).

"Armored Cars/Carriers":
There are occasionally "4 armored personell carriers" listed already in the Heavy SU Regiment, which goes on top of the fact that the Heavy SU Regiment has 104 more men - ...throught the whole "Recon/Armored Car"-situation or because of simply needing more Support (which may also contribute to that 104men difference obviously). Another question is wheather BA-64 or Lend-Lease Scout Cars were used ...or if Bren Carriers were around ...and so on, I can not say for sure (SMG Squads in "Guards" formations were supposedly transported in APCs - the heavy Regiments were all Guards I think).
What stands out is that the Brigade (heavy/medium) got an Recon Company - I can't tell its full setup but this would indicate 9Squads (usually...) - those are present in armored carriers being "Mech. Inf.", which is fine. On top the BA-64 of the Regiments are still around, which is fine (Sources vary on them).


So two questions remain,
- APC mounted Squads in the Regiments yes/no (and in return impact on the Brigade TOEs as well)
- Recon Platoon Squads (unarmored) in Regiments potentially missing (and in return impact on the Brigade TOEs as well)
(- sapper composition)

Not sure if this helps but....

Not sure if this helps but....

That belongs to the other Thread.
It states 1944, but that's the earlier numbers of SPGs per Regiment. (12/16/21) - but also contains 100+ SMGs (even for the SU-76)...
