The Überschwerer Kampfschreitpanzer is an awesome but little-known walking tank that was used in the German invasion of Russia during WWII.
As the war progressed, the Überschwerer Kampfschreitpanzers became less of an asset and more of a liability. Their height made it nearly impossible to hide them, and at least one was totally destroyed and another wrecked beyond repair by a concentrated rocket attack from the so-called "Stalin's Organs." Several others were damaged from artillery barrages, Russian dive bombers claimed another, and if reports are correct, one of the last Fortresses was taken by several P-38 Lightning pilots, who brought it down with wing-mounted rockets.
Where was this in my high school history book?
