originally a concept for the Nazis during WW2. this was going to be the largest tank ever to be constructed. its primary purpose was to combine heavy fire power with unbreakable armor, BUT there were too many flaws that arrived.
1.the vehicle would sink in the mud (Litterally)
2.it was too big and would be easily targeted by aircraft
3.the cost for production, men to operate, and training mechanics who were already being stressed out having to learn about the Tiger Tanks that were quickly being upgraded and the many types of Panzers and the new Panther Tank.
LUCKLY this tank never seen any battle because it didnt make it to prototypes because resources were needed elsewhere for the war. so what could have been The worlds largest tank would never see a battle.
