Did you ever hear the tragedy of King Tiger the heavy? It's not a story the Panzerwaffe would tell you. It's a wehraboo legend. King Tiger was a heavy tank of the Wehrmacht, so armoured and so deadly he could use his cannon to influence the 88 milimeter shells to burn Shermans. He had such an uneccesary amount of armour he could even keep the ones who crewed him... from dying. German tank design theory is a pathway to many monstrosities some considered to be underpowered. He became so up-armoured and heavy that the only thing he feared was destroying his transmission, which eventually of course he did. Unfortunately, he taught his adversaries everything he knew. Then his adversaries copied the good parts of his design after the war. It's ironic. He could save others from damage, but not himself.
Is it possible to learn this power?
Not from an Ally.
