Class 105 Infantry tank

10, 11 Matilda II, CS - there is no trace of Matilda II in Polish service.

They could be replaced with Churchill II, used for training from around 8/41 until 5/42 (data like British Churchill I, but with Besa BMG instead of 3in CSH).
There's no evidence, if Polish units had also Churchill I.

16 Sherman I
17 Sherman V
19 Sherman IB - I can't understand a reason why these tanks are used in late-war Infantry Tank units, if they are doubled as ordinary Medium tanks in the OOB (and even tripled as CS tanks). There were no infantry tank units in Polish forces at that time and Sherman tanks were used in combat in the 1st Armoured Division and 2nd Armoured Brigade, not infantry tank units. IMO they could be removed. Otherwise, they should be corrected, accordingly with units 26, 27, 29 (described later).

446 Matilda I - used for training from 9/41 until 9/42 only (now: 7/40-12/40).
Max speed was 13 km/h (now 6) [Magnuski] - same for the British OOB units 27 and 112.

There could be also variant with .50 Vickers TMG, possibly replacing unit 11 Matilda II.

457 FT-18 - there was no official designation "FT-18", and such designation isn't met in Poland (new works suggest though, that even a popular "FT-17" isn't an official designation, and they were just "Renault FT"). Anyway, I suggest a name "FT-17 /37mm" or "Renault FT 37mm"

I don't know why are they supposed to be used until 10/41 - they were used by the Poles until a fall of France in 6/40 only, and for training (in fact, they ceased to be used in 10/39 and were given by the French again in 3/40).

Is radio 1 correct?

471 - FR Char-D2 - Available 11/039 to 06/040
472 - FR Char-B1 - Available 11/039 to 06/040 - again, they are French tanks, not used by the Poles (and I assume, that the Polish infantry did not even met these types in field).

Polish forces in France used in combat R-35, which was by definition an infantry tank, and is forgotten for that period in the OOB. They should be used in 5-6/40. Both variants with short and long 37mm guns were used (according to Magnuski, long guns had platoons' commanders).
Most probably there were 3-tank platoons - four platoons and a commander's tank created a company (like in a Polish 1939 R-35 battalion).

Also R-40 tanks were used in 6/40, all with long 37mm guns, in uniform companies.

R-35 tank can replace #477 H-35 tank - there were only few (2?) used for training only.

It's a matter of choice if R-35 should be 13 or 105 class. Maybe there should be created separate uniform units with R-40 and mixed units with R-35 short barrel and long barrel for a commander. FT-17 with MG / gun could fit into the same formations (gun for a commander - they were used for training only anyway).

---
As a result, all class 105 Inf tank formations need to be changed - they should end in 6/40 and start again in 8/41 (Churchill) until 9/42 (Matilda I).
