The outbreak of World War II in 1939 heralded the arrival of a new era in military strategy, characterized by speed, surprise, and relentless coordination. At the heart of this revolution was Blitzkrieg, or "lightning warfare," a doctrine developed and executed primarily by Nazi Germany. Blitzkrieg was a military strategy that sought to overcome the static, trench-based warfare that had defined World War I. The tactics were designed to strike quickly and decisively, bypassing traditional defenses and causing maximum disruption. Its goal was not just to win battles but to create a psychological shock, overwhelming the enemy with rapid, coordinated strikes before they could mount a defense.

Unlike previous strategies that relied heavily on prolonged engagements and entrenched frontlines, Blitzkrieg emphasized speed and flexibility. The term itself was popularized by the media, but it aptly described the essence of the tactics: a rapid, forceful onslaught combining armored vehicles, infantry, and air support in a synchronized fashion. The Wehrmacht, under the leadership of figures like General Heinz Guderian, adapted the lessons of the past and fused them with new technology, creating a military machine that was faster and more mobile than any seen before.

The strategy was grounded in the belief that modern warfare required more than just brute force; it needed precision, rapid maneuvering, and the element of surprise. The mechanized forces, including tanks (Panzer divisions) and aircraft (Luftwaffe), worked in tandem to create an unstoppable offensive. They would punch through enemy lines with armored columns and then encircle and isolate units, preventing them from retreating or reinforcing. The Luftwaffe, meanwhile, would provide air superiority, neutralizing enemy air forces and bombing key infrastructure.
