unit 21 IS-85 in LWP know as JS-1 (Józef Stalin-1) polish transliteration was in fact in small number used in LWP training school first in Riazań and then moved to Rembertów near Warszawa. Probably adding a new Training tanks purchase option may solve problem. That is why this unit was added to orginal LWP OOB. My source was "Wozy Bojowe LWP 1943-1983" by Janusz Magnuski
26 M4A2 (76) There were added because also I found in the same book that Scherman's in short period temporary was used during fight in Gdańsk (Danzig) in 1945 with polish crews they were given by soviet unit just for street fighting and then returned back to owners. But of course except this short period of battle usage some Sherman's belongs to training school in Riazań or was was given for exercises by soviets.
There is a also Sherman in LWP unit description LWP on German soil so small number was again used in May-July 1945 meaby was transferred from tanks school or soviet units to replace loses.

27 SU-57 That was an error to add soviet machine-guns what I read and also soviet units photos suggest usually in leand-lase equipment American MG was retained ad used. So if they were rearmed that were because repairs etc. so soviet MG on them was rare the same with
46 M3A1 Scout Car as was mentioned earlier
33,34 SU-100 as you correctly guess was described only in training unit in small number in Rembertów not used by front-line divisions more after war 1946 were used in bigger number as standard equipment.
38 SU-152 was obsolete in 1944 and small number also in tanks school.
In school unit were also three T-60 used to end of 1945 and small number of KW-1 & five KW-85 obsolete used only for training.
