How did the Americans destroy the German's tanks?
With air power; especially the P-47 Thunderbolt; which is why the A-10 Thunderbolt II (aka Warthog) tank killer was named after the WW2 P-47.
Probably fuel. The German plan actually called for capturing enough Allied fuel to keep their offensive moving, as the Germans had insufficient fuel of their own. Nothing really gives a better indication of the desperation of the entire plan than this, that for its success, it depended on captured supplies. Individual Americans managed to destroy fuel dumps before they were taken by the Germans. When the Germans withdrew from the Bulge, they left behind dozens…
Tanks were used in World War 1 and the Allied tanks were better equipped than the germans' although the germans' were bigger and i think they were faster the Allied tanks were superior to their enemies' WW1 was when tanks were used in large scale for the first time but i think they were invented some time before the war but not long before. hope that helps!!! :-)
