KV-VI Behemoth was more than a landship, it was a Communist wet dream. It had some hilarious history, too: "The first prototype was completed in December 1941 and was rushed into the defense of Moscow. In its first action during a dense winter fog, the rear turret accidentally fired into the center turret. The resulting explosion completely destroyed the vehicle. The second prototype was completed in January 1942, and was sent to the Leningrad front. This one had indicators installed to show whe another turret was in the line of fire. In its initial attack on the Germans, the tank broke in half when crossing a ravine."
Crew: 15 men and one Commissar. The KV-VI was nicknamed "Stalin's Orchestra" by the few Germans that encountered it because of the variety of weapons it deployed.

UPDATE: The last crazy machine should perhaps be served with the "prank alert" warning. Regardless of how we want it to be true, and elaborate history behind it, there is suspiciously little information about it on the web. So, I'd take it with a grain of salt.
Скорее всего Вы правы, это наверное выдумка.
