You know, when you make a game about tanks, make sure you employ people who understand them and don’t post garbage:
STB1 was a Type 74 prototype, not Type 64 (there was no such thing) and it’s not from the 50′s, it’s from 1969. Just to be clear, this incorrect information is not WG EU’s fault, it appeared in the official press release too.
The same mistake is repeated on the portal.
