Question

what is the best definition of a \blitzkrieg\?
○ devastating airplane attack
○ rapid invasion by air and land
○ attack by multiple infantry troops
○ destruction of airplanes and tanks

Explanation:

Blitzkrieg, a German military tactic used in World War II, relies on coordinated, fast-moving attacks combining air support (to disrupt enemy defenses and supply lines) and land forces (tanks and motorized infantry) to quickly break through enemy lines and encircle forces. The other options are too narrow: it is not only an airplane attack, not just infantry, nor just destruction of equipment.

Answer:

rapid invasion by air and land
