Eric urgently recalled Hoffman, and the visit to Institute No. 12 had to be temporarily suspended. Hoffmann patted the "Opel" truck nostalgically, left other investigators of the United Front Work Department, and rushed directly to Berlin by car.

At noon, Hoffmann, who had rushed back from Dresden all the way to the United Front Work Department, did not have time to return to the United Front Work Department to deal with military affairs, nor did he meet with his colleagues, so he drove directly to the Hansa Felt Palace.

"Dear Mr. President, Hoffman, Chief of Staff of the United Front Work Department, has been ordered to come, please instruct!" Because Hoffman was going to study at the No. 12 Institute, he deliberately wore a brand-new general's uniform, and the gold sword on the cap badge, the collar flower and the shining gold sword on the epaulette were very dazzling. Walking to the door of the president's office, Hoffman gave Eric a standard military salute.

The sword on Hoffman's costume is the symbol of a first-class general, and it is also the first gold sword issued after the establishment of the German Confederation, which shows how much honor Eric gave Hoffman.

Eric knew that Hoffman would be back on time, because they were going to discuss Germany's top-secret plan, so the number of people entering and leaving the presidential palace was relatively small, and there were also a few more plainclothes security guards, and even the director of the presidential office Annata was not allowed to enter at will without special instructions. This is a high-level dialogue in Germany, as has been the case with Brauchitsch and Stresemann, among others.

"Your Excellency Chief of the General Staff, on the phone, you said that the 'Opel' truck is related to your important plan, what is it? Now it can be said. Eric personally handed Hoffman a cup of hot tea and leaned back on the couch.

"Oh, this is a thing of the past, and I feel it too." Hoffman was about to drink tea when he saw Eric asking, so he had to answer first.

"Let's have tea first, my chief of staff, speak slowly, don't worry." Eric noticed that Hoffman had a dry mouth.

"Do you remember when you fought on the Western Front?" Hoffman didn't answer Eric, but asked rhetorically.

"There have been so many battles on the Western Front, I don't know what the chief of staff is talking about?" Eric made Hoffman so confused that he didn't know what he wanted to say.

"It was the tank battalion assault commanded by Rommel, mainly against the blitzkrieg in Paris, have you ever imagined why the risk was so high in the first place?" Hoffman said with a very solemn expression, and a series of questions.

"The battlefield supplies were seriously unable to keep up, and although the troops were stubborn and stubborn, they could not effectively control the results of the victory, let alone maintain the troops for a long time interspersed with surprise attacks, and a back and forth maneuver made more than half of the First Armored Division at that time lie down." Eric certainly remembers the danger. The Germans now only know that General Rommel commanded the armored forces to successfully raid and enter Paris first, but they do not realize that the operation is very risky.

In order to achieve the purpose of rapid assault, the 1st Panzer Division had to abandon most of the armored vehicles and other baggage equipment in order to ensure sufficient fuel and temporary supplies, and only maintained the fuel and ammunition required by one tank battalion.

After the troops entered the territory of France, they were unfamiliar with the place, and their eyes were blackened, because after the defeat of the large French army, the small units that were attacked and scattered hurriedly hid in the hidden areas of the mountains and forests, but instead became a security hazard for the German logistics troops, making the long supply lines of the German army intermittent and uncommunicable. Although the logistics department used a lot of animal power, the speed of transportation could not keep up with the pace of mechanized troops, and sometimes it was attacked and surrounded by small French forces.

"Mr. President's memory is really good, as the so-called one sentence is broken. I just want to use this truck to fill the gap in logistics supply, and this is related to the victory or defeat of Germany in the future war, for example, in the face of a behemoth like Russia, no matter how advanced the weapons are, no matter how brave and good our troops are, if there is no strong logistics supply, even if we win tactically, we will be defeated strategically, because we cannot maintain the long-term survival and continuous operation of this force. I don't know if it's correct, so please ask Mr. President for advice. "Hoffman was a good student, and every fight was his learning material.

When Eric was the chief of logistics on the Eastern Front of the German army, the logistics planning also benefited Hoffmann a lot, so he had the plan to fight on the eastern and western fronts at the same time. The Germans decisively hit one of them with heavy blows, turned their heads and attacked the other together, and the effect was very significant.

The strategy of exerting strength to the maximum limit and gathering and destroying the enemy is successful, but it is impossible to be successful at every try, although the scattered forces can contain a strong enemy, but the strength is also the weakest, and it is very easy for the enemy to break through. However, this only belongs to the category of tactics, and only a strong logistical support capability can make a super-strong attacking force always be in a state of readiness, so the logistical superiority of motorization will be revealed.

Motorized troops, which were previously unthinkable, now have a chance to be realized. Just as Opel unveiled the sdkfz 305 prototype that delighted Hoffman, Eric was about to sell it to an almost unheard of country in the East. This made the chief of the General Staff of the United Front Work Department unhappy.

Hoffman has his own plans, Eric has his own plans, and the two do not conflict and contradict each other, but only look at the problem to a different degree.

The SDKFZ305 could not meet Eric's logistical expectations, and wheeled trucks alone could not provide unobstructed supplies, so he wanted to calmly deploy a large army and supply troops on the vast Eastern Front. Eric needed a combination of four-wheel drive trucks and half-track trucks as a transfer force, and the main transport task could only be handed over to the railway.

In the construction of infrastructure in Germany for several consecutive years, there has been significant progress in laying railway tracks quickly and effectively, such as cement blankets, etc., which have begun to be finalized, no longer in the experimental stage, and have entered practical use.

"Don't bother with my chief of staff, to be honest, this truck may really not be as good as you think, you should know that my debut started from logistics, and I am very surprised that you didn't discuss this issue with me in advance." Eric said, feigning annoyance.

"I'm sorry, Mr. President, you have so much work to do, and if you need to take charge of such a small problem, so many salaried people in Germany will be able to feed the country for nothing. Please be sure to understand my good intentions and never be arrogant. Hoffman apologized and showed humility and loyalty.
