Answer
Brief Explanations:
During World War II, Germany's Blitzkrieg strategy relied on coordinated air - attacks and fast - moving ground troops, which caught many countries off - guard and made it difficult to stop the invasions. Bombs and torpedoes alone were not the main reason for the difficulty in stopping invasions. U - boats were mainly used for naval warfare and disrupting supply lines rather than direct land invasions. Germany's navy was not as powerful as its air and ground forces in terms of facilitating land invasions in Europe.
Answer:
Germany's air attacks and fast - moving ground troops
