Upgrade chart Russian units

you can upgrade towed artillery for peanuts to any other variant even though they have almost nothing in common. Same with towed AT guns - each one is a different design yet cheaply upgradeable between models. Go figure

One could argue that while the guns are different, the crews would require relatively little retraining when getting a new gun- going from a 5cm PaK to a 7.5cm PaK isn't the same as going from a 5cm PaK to a StuG III, which is a totally different skill set. Similarly, the Me 410 was not built by upgrading existing Me 110 airframes, but a pilot would have found it a relatively easy switch.

We could argue even further - switching from a Pz IV to a Panther tank would require similarly minor adjustments, the crew layout and roles were exactly the same, only the "hardware" got better Yet the price is steep...

Anyway, it just proves that there is no "internal consistency" in the vanilla equipment file when it comes to certain choices. They are just....choices

KV85 puzzles me.
It was supposed to be a way to keep KV series competitive but isn't counted as KV series upgrade. Given it arrives at near enough the same time as IS1 which is better in most respects, it would make sense to keep the KV85 as a KV upgrade so you can have the more expensive but better IS1 or the second best but cheaper KV85.

The Churchill croc in Allied corps is out of series with the other Churchills but at least that is such a good upgrade with its 140% RoF it's well worth it, but the KV85 is only one step up rather than a real change.

I like the situations where upgrading isn't clear-cut and you have to make a choice (think the 109 E/F upgrade where you have to downgrade attack stats to get other benefits).

As we know, the KV85 is a KV1S with a new turret and 85mm gun.
KV1 -> KV1S -> KV85.
The KV1S is not in the game, therefore my guess is the developers didn't know much about this line development, but i'm grateful nonetheless for the game they made.

The IS1 is an IS85 renamed to IS1 and production switched to IS2 with the 122mm gun in January 1944. IS1 issued with 85mm guns were re-armed with the 122mm gun. (in 1944)
