Answer:
The Nazi military tactic that led to their rapid success in World War II was the blitzkrieg.
Explanation:
Blitzkrieg is a military tactic based on the combination of mechanization, air power and telecommunications, aimed at the development of rapid and overwhelming maneuvers designed to break down enemy lines at their weakest points and then proceed to encircle and destroy isolated units, without giving any ability to react, given the constant state of movement of the attacking units.
Crowned by a resounding success during World War II, in the countryside of Poland, France and the Balkans, the Blitzkrieg showed the first shortcomings during the Barbarossa Operation. In fact, while on the western battlefields the operational distances were estimated in the order of tens of miles (allowing the mechanized infantry to almost never lose contact with the advancing armored units), in the endless Russian steppes the formations often ended up enormously lengthening, distributing the attack units along impressive-sized routes, making the aggregate infantry accumulate delays in the order of days with respect to the Panzer-Division.
He determined that the laws of physics are the same for all non-accelerating observers, and that the speed of light in a vacuum was independent of the motion of all observers.
