Dude, do you want me to look up screenshots of the Ostwind, the P4 and the Jagdpanzer to prove that those little details have always been there? I mean hell, the goddamn Jagdpanzer portrait even has those spare wheels on it which means it has been there since release as Relic would never change a portrait for such a small change. It's the same with the Panzer IV. Here's a steam store screenshot for one of the skins:
What makes you think these are the decals? All these things are just part of the model lol. They were already there. They've been there since the release of the game (or the release of WFA in the JP4's case).
Lol they didn't replace the old Pz IV to get decals to work or some shit, they replaced it because the old model was shitty and outsourced. Besides looking more like an actual Pz IV, the new one is just a higher quality model made by Relic themselves.
The thing is western allies were cowards and scumbags which bombed german civilian cities with fire bombs, dropped atomic bombs on civlians in Japan, cowardly waited until 1945 to open a second front when war was already single handendly won by Red Army who were pure heroes
I dont want you to even dare to compare western allied cowardly backstabbing (Operation Unthinkable) scumbags with russian heroes of WW2
