How did advancements in technology make blitzkrieg possible during World War 2?

Advancements in technology played a crucial role in making blitzkrieg tactics effective during World War II. The development of fast tanks, such as the Panzer, allowed for rapid ground movement and deep penetration into enemy territory. Additionally, improvements in radio communication facilitated coordinated attacks between infantry, tanks, and air support, enabling swift and dynamic maneuvers. Together, these technological innovations allowed German forces to execute surprise attacks and overwhelm their opponents before they could effectively respond.
