remember the “Nuts and Bolts” (or how is it called) series from the EU server, describing various parts of the vehicle? Well, Russian server has that too (translated into Russian of course), but they also have another series, called Evolution of Tanks. It is narrated by Dmitryi “Goblin” Puchkov, who is apparently a well-known person in Russia for his translations of movies to Russian.
It’s longer, more detailed and pretty interesting. And it has (at least this part does) English subtitles. So, you can have a look – don’t forget to turn the subtitles on.
