This absurdly oversized vehicle is the Land Battleship, a juggernaut that supposedly ran over Nazis in World War II. This 1941 illustration from Mechanix Illustrated is, as commenters over at Modern Mechanix astutely point out, an artistic embellishment of real Soviet tanks such as the KV. From now on, I'm just going to refer to all tanks as "land battleships." I already call planes "aero-sedans," so it won't be that difficult.
