"Yes, the most successful DD tank was the Sherman"
But on D-Day the American Navy panicked and released much too far from shore so many of them sank, while the RN looked at the conditions and decided to go right in. The US weakness is to rely too much on technology while not paying attention to the human side, which is how they manage to have a heavily armed police force that kills hundreds of people every year (exact numbers unknown but > 450) while we have a much less armed police force that manages to arrest people while hardly shooting anybody.
You could argue that it's this failure to pay proper attention to the education and training of the non-élites that has resulted in the H1B issue. There's enough Americans that a decent State educational system would make the US an exporter, not an importer, of talent.
