What best describes Germany's military strategy at the start of World War 2?

At the start of World War II, Germany's military strategy was characterized by the Blitzkrieg, or "lightning war," tactic, which emphasized rapid, coordinated assaults using combined arms forces—infantry, tanks, and air support—to quickly overwhelm and incapacitate enemy defenses. This approach aimed to achieve swift victories and minimize prolonged conflicts by exploiting speed and surprise. The invasion of Poland in September 1939 exemplified this strategy, leading to a quick and decisive German victory. Overall, Germany sought to capitalize on its technological advancements and military innovations to achieve dominance in Europe.
