Well I found the mod's db webpage, but there are many mistakes:
In the soviet union units page, the list does not include kv1s and lists the zis3 as a doctrine unit, yet it's not included in any of the doctrines!
In the soviet doctrines page, the mechanized army list says the upgraded optics for su76s, but since the su76 will only be available in the campaign, whatis the point of the ability in multiplayer: either it's useless or a mistake!
I've already suggested what it should be instead (general t34 upgrades: armor, sights, aircraft engine, better crew, flamethrower)
