But the actual solutions were the shock troops, you know? The tanks and the anti-tank defence kinda reached parity by the middle of the WW2, so tanks became rather ineffective at breaking through the field defences. Solution? Specifically trained infantry groups that would infiltrate and destroy the fortifications, Germans used it since the early WW2. And here's a particularly interesting document from the Soviet sid…
Given the Ludendorff offensive failed I don't think you can call stormtroopers alone a solution.

Quoting wikipedia: > By 1918, tank capabilities and tactics improved, their numbers increased and, combined with French tanks, finally helped…
He's saying that tanks became less effective during WW2, at first offense was overpowering defense thanks to tanks, airplanes and improved logistics. During WW2 defense started getting closer to offense, at least on land (air power improved greatly and it was the thing which facilitated all major offensives).
