KV-VI.

This is coolbert:

I am not sure if this is a joke or what. Is taken from an Internet web site called Deviant Art.

The land-battleship Soviet style. From the era of World War Two! AN experiment and only that. The grandiose and unstoppable weapons system that was a total failure. Good paper but poor in execution.

 "EXPERIMENTS OF WAR"

"Russian Land-Battleship KV-VI"

The land warship almost literally so!

"Inspiration for the KV-VI came from news that one single KV-2 had held off an entire German tank division for 24 hours."

KV-VI a tracked vehicle of stupendous size. Incorporating an entire combined-arms weapons system into one vehicle. Tank turrets, multiple rocket launcher, artillery, anti-aircraft! The total package. Evidently three prototypes of the KV-VI were built, all unsuccessful! Click on image for a magnified view.

KV-VI an apparatus just from appearance alone ungainly and doomed to failure for a variety of reasons from the start. 

Or is this all done for comedy and humor of some sort?
