Russia, as we all know, has very powerful, at times absurd, Anglepen modifiers on their shells.
As Far as I can tell the reason for this is twofold
- Beta and Early release russian Techtree performance
Russia was not that good of a nation eraly on. The KV 2 was a blast, the T50 a nightmare to fight but overall With the Release of the US tree its performance was lacking, especially with the back then better performance of APCR and solid AP and a much worse APHE performance.
So Russia got a buff to their anglepen in one of the APHE rebalances and overall penetration adjustments
- Real life.
As far As I could find, russia actually had shells which performed absurdly well against angled armour. But it suffered from poor penetration against flat surfaces. The Guns I could find who used said ammunition where the 76mm L-11 and F-34 guns used on the eraly KV 1 and T34 models.
Specifically the BR 350A round is mentioned, but some others probably also saw service
For those who want to see aproximation on how it worked and why it is strange:
The Thing is all russian Guns and SHells have increased angle performance, and not just a few. The 122mm Guns and almost certainly the 85mm guns as well as 100mm guns never used this kind of shell. Their design is much more in line with evbery other nations design and the 365K seems to be inspired by the german 75 or 88 guns but that might just be a coincidence
Here a russian BR 365 85 mm shell (the second from the left is the APCBC shell either the A or K model we have in game:
and here a german 8.8cm Pz Gr 39 from the Tiger I
Ofc many will again despise the Wiokipedia sources (albeit the fact that the Russian one is a picture from a piece from Kubinka). So if you have better sources please share them.
As it stands the russian angle performance needs to go. It is unrealistic and quite frankly causes balancing issues as well as the occasional bug in the physics (Shell normalising to impossible degrees).
If Gajin wants every shell to be based on the same model (which is impossible but thats just my two cents) they should at the very least not so obviously use wrong data to get their numbers. As the DeMarr system often disagrees with their own data)
So my simple suggestion is to remove the special angle pen magic from russian guns except for the ones using the BR 350A or B shell which both saw use during WW II and both had a special design to facilitate their increased angle performance. The other russian Shells have all the benefits of that design but none of the downsides making their performance pure fantasy.
