Why was Germany so EFFECTIVE in the Second World War? | Documentary

After the limitations imposed by the Treaty of Versailles, the German army transformed into a highly trained professional force, based on mission command, rigorous planning, and a military culture oriented toward initiative. Under the rearmament driven by Adolf Hitler, the integration of tanks, radio, and air support enabled the development of fast and coordinated campaigns. German effectiveness became evident during the Invasion of Poland and the Battle of France, where the combination of speed, concentration of forces, and disruption of enemy communications dismantled entire armies within a few weeks. This same model was applied in Operation Barbarossa, achieving enormous initial encirclements against the Red Army. However, the vast Soviet territorial depth, logistical problems, climate, and the USSR’s capacity for mobilization began to wear down the German system, especially after the Battle of Moscow. The war shifted from lightning campaigns to a war of attrition, in which Germany’s initial advantage began to erode.
