I stumbled, by chance, on this Russian-language Youtube video showing the inside of a T34/85 with a noob trying to figure out how to start the engine and driving the T34/ 85, learning how to load the gun and even firing it. Interesting stuff. It's in Russian but with English subtitles. Interesting to see the inside and learn about the basic operation of that iconic tank and hear the real sounds of the engine, the tracks, the rotating turret and the gun shot.
