Guderian was named after Manstein and Rommel. Why not marshal?

1. After the Moscow Battle, guderian's disobedient retreat on the battlefield in order to safeguard the interests of soldiers and his face-to-face accusation of the defeat of German high-level officials angered Hitler, who was dismissed and put into reserve service. When guderian returned home, he found the Gestapo watching him! That guderian had lost Hitler's trust and was left out in the cold. In 2.43, paulus surrendered as a marshal, which made Hitler furious and vowed not to be a marshal. He knew that the end of World War II was only because of his own efforts that he was forced to seal two more marshals, and he had already sealed 28 marshals in one breath! It shows that Hitler was extremely distrustful of the German generals at that time, and guderian, as an extremely rebellious general with no meritorious military service, was even more difficult to seal. In 3.43, because of the desperate battlefield situation, Hitler was forced to reuse guderian as the director of German armored forces. Although the fake orangutan made some apologies when he called guderian again, he hated guderian even more when the gap between him and guderian persisted, especially after guderian had quarreled with Hitler for many times over military issues. After that, he used guderian as the German chief of staff when no one was available, but soon after a fierce quarrel, guderian was dismissed again, indicating that Hitler's feelings for guderian were deteriorating, and his dependence on guderian was only due to guderian's ability. From his later refusal to let guderian go to the battlefield to command the army, it can be seen that he did not give real power. There are also strong anti-ancient forces within the German army. Guderian's own armored forces crowded out the traditional army troops-cavalry, and offended a large number of cavalry officers. His blitzkrieg theory was also strongly opposed by conservative German high-level officials. Guderian resisted, not only pulling guderian back on the battlefield, but also trying to find trouble with guderian on the battlefield. Guderian and conservative Kruger, for example, are stiff. Under their obstruction, it is even more impossible for guderian to become a marshal.
