In a remote room in the Prince's Palace, only Adrian and Brauchitsch were here.

Every little Adrian said, Brauchitsch would take note of it. When Adrian had finished, Brauchitsch looked at it again from beginning to end. This is Adrian's report on armed transporters based on the previous battles of the armored division. He found a few problems in general.

The first point, accounting for 40% of the passability problem, the passability of the crawler is stronger than that of the wheeled type, but it also has its own limitations, that is, the weight problem, resulting in many places can not pass, and it is necessary to build a more solid passage road. Adrian can't think of a way to solve this problem for the time being, unless he thinks of a way to solve the problem of materials in the future, the current stage of material development is only in its infancy, although it has caught up with the world, but it will take a long time from practical application and manufacturing. The materials that have taken a lot of effort to make are not helpful for practical applications, and a way must be found for mass production, otherwise it will be a chicken rib. Eric Adrian, who is familiar with history, of course, knows the scientific and technological level of the Third Reich in the original trajectory, not to mention ranking first in the world at that time, but he is also at the forefront of the world in many aspects, but after all, he did not start mass production in many R&D projects because he did not find a way to mass production. Adrian doesn't want this, R&D is one thing, application is one thing, and it has to be looked at separately.

When designing and building the armed transporter, Adrian made a choice of materials, using ordinary steel for mass production, rather than choosing materials that would take longer. The concessions made in the light of the realities of the situation are not irresponsible on weapons and equipment, but a necessary trade-off.

The second point is the problem of speed and comfort, in order to speed up the launch of the campaign, a gasoline engine of the Benz company was directly applied, this kind of tandem engine originally used for lighter cars, even if it has been temporarily improved, has not made much progress in power, not to mention that in order to support the heavier armed transporter, all the parts have been reinforced and thickened. This makes the space in the car less comfortable. Reinforcement, thickened parts, and heavy armor are not fast.

As for the other issues, which were trivial due to limited working hours, Adrian did not focus on them.

Brauchitsch was no stranger to these problems, and he had experienced them firsthand, and although his command car was better than the others', similar problems arose.

Brauchitsch was most interested in one of Adrian's command and communication problems, because of the limitations of technology, he did not think that there was any problem with command and communication before, or that the battlefield relied on the messengers who braved artillery fire to transmit messages. For the first time, radio communications formed an outline in his mind, and his comprehension was not bad, and of course he understood the tactical implications of timely radio communications. The action can be more rapid, and the commander can even make changes at any time according to the form of the battlefield, which was not possible before, and it is a great test of the commander's adaptability and foresight ability, and it is necessary to command in advance.

There are many hurdles to overcome when moving something as expensive as radio equipment onto a bumpy vehicle, starting with the selection of materials and the streamlining of equipment. Adrian did not use the radio equipment on the armed transporter because of the lack of space, the poor protection and the high damage rate. Radio equipment is not cheap, and although it has the support of the state, it cannot reach the point where it is not distressed if it is damaged. He was waiting for the appearance of tanks, which would minimize such losses with a high level of protection. Now the time is ripe for him to make this communication equipment completely change the mode of command.

Adrian then instructed Brauchitsch that at the next Monday's arms purchase meeting, there were only three designs for the tank.

One is a design scheme with protection as the primary, mobility secondary, and firepower as the supplement, and the main role is to act as a fist force to break through the enemy's defense line.

The second type is a mobile unit that is mainly mobile, followed by firepower, and supplemented by defense, and is used as a mobile force to cover the first plan, which can make up for some defensive loopholes to a limited extent.

The third option is a mobile strike platform that destroys the enemy's armored forces with firepower as the main force, defense secondary, and mobility as a supplement.

The priority of these three indicators depends on the situation, at the current stage, Adrian's three plans can be well adapted to the current battlefield, no matter how far the British tank has improved, I believe that it cannot escape the limitations of the times, just upgrade.

Brauchitsch carefully examined these indicators as he sorted them out, and asked Adrian what he didn't understand, and the latter would patiently answer with limited understanding. Adrian also had no experience, and whether it was really as practical as it was designed needed to be tested in practice.
