I hope you are trolling. It gives massive advantages to us and su players (lots more survivable infantry than it should be) and absolutely ruins brits with amasing bonuses such as:
What? I'm sorry, but while it affects all factions equally, the soviet union is affected this game hopelessly. Now we know why cons and penals are so shit in the lategame, and the only choice is maxims. While all other factions get lategame infantry, soviet union relies on superior vet . The vet on both penals and cons is superior when compared to volks and grens. But that doesnt matter because it doesn't work
Axis on the other hand dont get affected so hard by this change, since their rifles are all very high accuracy , medium damage but low rate of fire (for example volks have 80% accuracy at long range) so the 40% accuracy bonus doesnt do much since their accuracy is already near 100%, and of course grens get the LMG so they arent as dependant on veterancy.
Soviets on the other hand have very low accuracy, low RoF, but high damage dealing weapons.
This is compensated by their vet. Penals for example at vet 2 get 40%, and at vet 3 get another 20% or 30% accuracy buff.
USF rifles is kinda hurt too since rifles are supposed to have superior vet from their axis counterpats.
Seriously, once this gets fixed the whole infantry combat starting from mid game and lategame will look completely different. Radical changes incoming
