The European nation: more than one country
No, the EU is not producing tanks for one EU army, that's not the reality of today and won't be the reality for the coming years. Then why is there a European nation inside WoT Blitz, you may ask? My guess is that all small European nations have too little tanks to warrant a seperate tech tree. This might change in the future, but for now, the tree consists of Finnish, Polish, Italian and Swedish tanks.
This makes it hard to exactly point a finger at the characteristics of this nation. Swedish and Italian tanks are totally different. The majority of the current tech tree are Italian tanks though, and the two currently existing premium tanks are both Italian. One of them sports the famous autoreloader, while the other is an improved version of the tier 6 in the tech tree. Both have good firepower and are very different from most tanks of other nations, making them rather unique and interesting.
