And now for the AFV notes:
The situation of the T-26 tanks is problematic. These vehicles were declared obsolete already in July 1944 and took large losses in summer 1944. They should really be placed in the obsolete tank category, since it is very unlikely that these death traps would have been used in combat in the 1950s. However, I am hesitant to do that because the AI pick list apparently includes light tanks even in the 1950s.
T-28e has a wrong main gun, should be L-10. I will assume use of Finnish AP, which was superior to captured Soviet WW2 AP.
T-34's have the ZiS-3 as the main gun. I will copy the correct F-34 from Russian OOB. Although test data for the F-34 is not available, AP Penetration with Finnish WW2 ammo can be interpolated to be 11 and a small amount of WW2 HEAT with penetration 8 was probably available for the T-34s post-WW2. I will also extend the range of the gun by 10 hexes to 70 in order to better match the long range ballistics of the Finnish AP.

The radio codes of WW2 vintage tanks are not very good. The Pz IVj was the most common WW2 medium tank in Finnish service, T-34-85 was second. The T-34 M42 was represented by exactly one tank (...). I will modify them so that hordes of T-34s are no longer selected.
Sabot penetration values of British 20-pounder and 77mm HV gun seem to be too low at muzzle; somebody probably made a poor job at extrapolation. I have used consensus numbers from web sources.
The T-54s in Finnish service were actually model T-54-3 a.k.a. M1951. Due to purchase date (1959) people have often assumed that they were T-54Bs, but T-54-3 has been confirmed by serious sources. Also, they lacked gun stabilizers, which closes the case. They were never modernized in Finland apart from the ammo and radios, so units 410 and 411 have wrong FC and RF values.
The penetrations of the PT-76's D56TS (weapon 086) are quite strange. It appears that the Sabot value is for the WW2 vintage BR-354P APCR and the AP value is for the 1950s streamlined BR-354N APCR. The HEAT value is probably for the 1955 fin-stabilized BK-354М. I'm going to change that so that the AP value (12) is for the post-WW2 BR-354 APCBC and the Sabot value (15, same range as AP) for the BR-354N. Source:
https://ru.wikipedia.org/wiki/ПТ-76, except BK-354М. I have no idea if the Soviets actually sold the latest BR-354N and BK-354М to Finland, but I assume so like the original OOB designer did...
The modernization of the T-55 in late 1980s did not include armor upgrades beyond the addition of side skirts, but it did include the Mecar M1000 APFSDS round. At the time it was the most advanced APFSDS round available for the D-10 gun with a high L/D monoblock tungsten alloy penetrator. The only estimation I have found about it is 350 mm @ 2000 meters @ 0 degree. Official figure was penetration of NATO Triple Heavy target at 3000 meters, which unfortunately does not tell us much. So, I took the newer Israeli/Romanian M309 round from the Romanian OOB as a rough guideline using available estimates and ended up with Sabot penetration 45. There were also rumors in the 1990s that the M1000 was supposed to penetrate T-72 turret at 1000 meters and with Sabot Pen 45 that is possible.
The T-55MS also got a new Swedish integrated FCS, the same in fact as the modernized version of the Ikv 91 tank destroyer, which has FC30. Also, according to tankers who served on both the T-55MS and the T-72M1, the former had a much better FCS. T-55MS is still used in small numbers, so I have made it available until 2020.
125mm D-81 penetrations assume Soviet domestic standard rounds. The HEAT numbers are too high (BK-14M HEAT was the best exported from the USSR). Finland also never purchased new HEAT rounds for the gun in the 1990s but continued to use the BK-14M.
No decisions yet on BMP-2 modernization. Probably it will not happen in the current economy, but I will push it a couple of years forward just in case.
XA-180 PaSi still very much in use. Modernization closer to XA-203 standard is planned, but has not started yet.
Vehicle grade Gen3 image intensifier is used on the XA-203 RWS, so Vision 30.
The FC etc. values for the AMV should be the same for both armaments, since the turret is the same. The .50 cal armed version had lower values for some reason.
BTR-50PUM1 was in Light APC class. It is a command vehicle, so FO Vehicle class in the game (although for many command vehicles that does not actually make much sense)
Leopard 2A5FIN was cancelled. Instead, Leopard 2A6 were bought from the Netherlands, so I copied the unit and the 120mm L55 gun from the Dutch OOB.
I may have forgotten some minor changes I made... But as usual:
