Logistics-It was precisely because this factor was ignored that Germany finally paralyzed its army. Germans are good at launching blitzkrieg in relatively small areas, short time and good weather conditions, such as invading Poland, France, Yugoslavia and Greece. However, when they attacked the Soviet Union at 194 1, the Soviet Union's huge depth, bad road conditions and bad weather exposed their logistical shortcomings. Due to the lack of enough trucks, the Germans still use mules and horses as transportation tools, which makes their infantry and supplies unable to keep up with the advancing speed of tanks. Transport planes could have helped the logistics of the troops, but Germany lost a lot of transport planes in the airborne operation in Crete, and later more transport planes were lost in vain in the air-drop assistance operation to avoid being trapped in Stalingrad and the whole army surrendering.
In addition to providing traditional food, water and ammunition for marching troops, tanks also need a lot of fuel and spare parts. This problem deepened with the war, paralyzing the German armored forces. Later German tanks, Tiger and Tiger King heavy tanks were technically very complicated and needed more fuel than earlier tanks. The loss of many heavy tanks is due to mechanical failure and fuel shortage, not enemy gunfire. So blitzkrieg needs not only tanks, but also high reliability, long enough travel and various auxiliary trucks. Germany was severely punished for neglecting the behind-the-scenes support needed behind the gorgeous stage of war. At the end of the war, the Soviet army improved their logistics supply system, so that their tanks could advance hundreds of miles without interruption, and sometimes even refuel during the journey, which was of course due to the technical reliability and simplicity of their vehicles.
