In the north of China, there is a large vast desert, climate changes, so that here has formed one after another no man's land, in a sense, these no man's land, for any country, represents a kind of scar, the northwest has begun to govern these places, from Europe a steady stream of manpower, supplemented here, millions of prisoners of war, can work in the most difficult state, not to mention that the northwest in a sense, did not blame them too harshly, in addition to the difficult environment, logistics supply, tents, working environment, etc., are in a state that can be solved, the best solution, even the work of digging tree pits, most of them are also done by machinery, only in the case that machinery can not replace manpower, will choose to let people work, in this case, not only the environment in the north is changing very quickly, these prisoners of war. It's not too painful, it's basically about 10 hours of work, outside of work, it's relatively peaceful, and it eats well and sleeps well.

In order to support this project, the Northwest Institute of Botany, and even a large number of greenhouses and experimental fields, have been put into the breeding of seedlings, scientific management, carefully selected a variety of drought-resistant and suitable plants to grow in the sand mold, which will be planted in many lands including deserts in the coming year.

It may not necessarily change the environment of the entire region in a short period of time, but it has taken a solid step, especially on the Loess Plateau, which has already shown signs of deterioration, consolidating water and soil, preventing wind and sand fixation. It was divided into 3 phases and lasted for 15 years. The Northwest Association has successively invested 55 billion yuan in the northwest for environmental management and planting trees and grass on the entire Loess Plateau. The completion of the return of forests and the return of farmland to grazing land will exceed 30,000 square kilometers, which will cause a reduction in grain production in the whole of China, but will completely change the climatic conditions in the entire northwest.

China has always had insufficient land, and both in later generations and now, relatively barren land is used. It seems that from the history of China, food has not been enough, so in history, as it is said in the Romance of the Three Kingdoms, the general trend of the world, when the time of stability has passed for two or three hundred years, when the population continues to reach a certain limit. Once you have a problem, it will be turbulent.

However, this point has little impact on the northwest, and the new land opened up in the western region. Coupled with the huge amount of land controlled overseas, it will supplement the output of this 45 million acres of land. The investment is staggeringly huge, land and money. The result is bright, minimal. In Yang Yuanzhao's view, in his lifetime. It will make the Yellow River, one of the mother rivers of the Chinese nation, green, and the resulting environment and subsequent consequences will continue to affect the development of the whole of China in the next 100 years and 1,000 years. At present, most of the uninhabited deserts in the northwest have not yet reached the time for planting trees and pastures, and at present, most of the uninhabited deserts still have little effect, and only a small part is used as a testing ground for the top-secret weapons of the Northwest Army, especially the weapons used by the army.

The research of tanks and armored vehicles, which began in 1911 and lasted three years, has gradually developed from the simplest ordinary armored vehicles to the present, and has gone through three generations, and tanks and armored vehicles have begun to become more and more powerful. The graphics of classic tanks and armored vehicles were handed over to the research institute as early as the beginning of the research, but because of this, a lot of detours were taken, and the appearance of the classic tanks and armored vehicles of later generations was very classic, otherwise it would not have been used by countless countries, but for the beginning of the 20th century, 100 years of science and technology, even if you know that these are the best, it is very difficult to solve, at the beginning, the researcher almost had no clue, many routes have died, and for a long time, there has not been much progress.

Fortunately, Yang Yuanzhao's timely release allowed the researchers to give full play to their ingenuity and rely on their own efforts to solve this problem, this time, like the finishing touch, solved this problem in a timely manner, the Northwest itself has all the conditions for the production of tanks and armored vehicles, various sub-projects, compared with the prototype of tanks and armored vehicles, there has been great progress, if it were not for Yang Yuanzhao's deliberate requirements for armored vehicles and tanks, with the necessary performance, even comparable to the main force of later generations, These tanks and armored vehicles have long been born.

Yang Yuanzhao is an engineer of the later generation of the team, is a graduate of the power department of a famous university, itself has a deep study of the world's most advanced engine, plus the BMW 999 engine and a variety of advanced metal materials provided by the all-in-one machine brought by the crossing, some advanced engines have gradually appeared, the horsepower of the powerful diesel engine has reached 600 horsepower, for the main engine of World War II, the volume is slightly larger, but for tanks and armored vehicles, power is the heart of the core, less power, There is no way that any design will work as it should, and this one can be used even more in front of it.

After the initial obstruction, Yang Yuanzhao decisively adopted a new method, just came up with the engine and simple things about the concept of later generations, such as wheeled infantry fighting vehicles, wheeled armor, tracked tank chassis, these are the most basic, engine, artillery and protection These basic concepts, the rest, left to the designers, by the way, put forward several requirements, such as strong reliability, simple structure, easy maintenance, convenient mass production, etc., and because of this, the armor of the Northwest has made a breakthrough.

Don't underestimate these requirements, this is after historical research, the northwest in the engine project, because of the all-in-one machine and Yang Yuanzhao itself excellent, has exceeded this era, you know, the future marketing of the whole world, supporting the military transport of the US military Dodge truck, is only 10 tons, the reason for such a small displacement, on the one hand, because the grade of the car and other metals is insufficient, on the other hand, the performance of the engine is insufficient

But now, under the design of the all-in-one machine and Yang Yuanzhao, the most powerful diesel engine has reached 600 horsepower, and the ordinary diesel engine has reached about 300 horsepower, miniaturization and production capacity have been available, so large military trucks with a transportation capacity of more than 25 tons and heavy tanks of about 50 tons have also appeared

Tonnage is always the basis of the tank, in fact, the first time the tank appeared in the First World War, whether it is a large tank or a French Renault, are light tanks under 20 tons, the weight and speed are very slow, in the eyes of Yang Yuanzhao, there is no practicability of later generations, in a sense, it is just that Britain and France were tortured by trench warfare to the extent that no one can be affected, and they are hard to piece together, breaking through the weapons of trench warfare, and the speed of the large tank is only 3 kilometers per hour, It's just a moving iron shell, and as for Renault, it's a little faster, but it still can't catch up with the performance of later armor.

Such a weapon had an excellent effect against unprotected infantry and positions that were not supported by large-caliber artillery. However, the slow speed was easily covered by the strategic artillery in the rear, especially with the density of artillery fire during the First World War. The tank made by Yang Yuanzhao was intended to make him a weapon for attacking, rather than a coffin, and after the tank had a huge effect in the early stage, it soon became a mobile coffin. So, a tank is very similar to a battleship, and there must be a perfect balance of speed, firepower, and even protection.

The 600 horsepower engine is the basic, you know, the main battle heavy tanks of World War II, most of their engines are 600 horsepower, from the T34 to the Tiger, to the United States and the United Kingdom main battle tanks.

Although there are still many problems to be solved, artillery technology, protective armor, and even the concept of protection are world-class, and the heavy tanks of the Northwest already have a foundation.

Researchers in the northwest, when they are trying to solve it, how can this tank become more and more like the T34 of later generations, in fact, it is no wonder that these requirements put forward by Yang Yuanzhao, and even the performance of low temperature resistance, are put forward with reference to the Soviet tank.

As the entire northwest, the first armored troops, the first armored brigade and the first special armored regiment, they are the first to contact the armored troops, strong armored performance and well-trained troops make them very confident in their own strength, but now, suddenly let them participate in the exercise, with the exercise of the 11th Army, this more or less surprised them, the first armored brigade and the first special armored regiment, all of them are high-level, the brigade commander is a major general, and the regiment commander is also a brigadier general, Basically, it is equivalent to the ranks of the first and second divisions of other troops, and since its establishment, it has always been trained independently, and now it is somewhat strange to receive such an order for joint training.

The roaring sound sounded, the first armored brigade has 250 armored vehicles, and the special armored regiment has 112 tanks, including 27 heavy ones, 35 medium ones, and the rest are all light, similar tactical drills have also been experienced, even if the first armored brigade is more numerous, it will be a complete defeat when it encounters heavy tanks, that is, ordinary medium and light tanks can resist one or two, and now they have to conduct joint training with all infantry troops, for them, it is simply hand-to-hand, and it is because they are familiar with the weapons in their hands that they are clear, how strong the armor is.

According to the plan of the exercise, they need to pass through an area of about 30 kilometers and surprise the infantry units of the three divisions that have already built positions in front, and they have already entered the field three days ago to form a relatively solid three-dimensional position, and their exercise project is how to break through this position and achieve success at the minimum cost.
