Holy fuck, I still can't believe what I'm seeing.
The vehicle on the left is clearly the Type 71 from Wot Blitz, while the vehicle on the right is one of the Ho-Ris. Looks like WG took the tier 9 Ho-Ri with sloped armor, and gave it the 15 cm Type 89 gun the tier 10 Ho-Ri has.
I think that someone at WG really was like "oh shit, Japan is a nation that exists", and decided to make up for it by what appears to be TWO new tech trees for Japan.
Now just buff the Type 5 Heavy and I'll literally ask for anything ever again.
