At the same time, the central authorities abolished the original structure of the Northeast Field Army, and the Northeast Military Region and the Field Army were reorganized into integrated leadership, and no leadership levels were set up separately. However, with regard to Yang Zhen's request for strengthening the leadership of the Northeast Military Region, the central authorities, which now lack cadres everywhere, have made great determinations, but in the end they have not been able to meet all of his demands.

For this series of changes, Yang Zhen has long been mentally prepared. But for him, he has neither the mind nor the time to care about these things now. An existential battle is imminent, and the heavy pre-war preparations make Yang Zhen so busy that he doesn't even have much time left to sleep.

After returning to the Northeast, Yang Zhen did not immediately return to Harbin. Instead, after entrusting all the work to Li Yanping and Guo Bingxun, he took a group of operational staff officers who came from the headquarters and secretly disguised himself as Mongolian herdsmen or traveling merchants. He personally rushed to the East and West Uzhumuqin Banner, Abaga Banner, Keshiketeng Banner, Weichang, and Fengning areas to secretly inspect ammunition and material hoarding points, as well as field airfield setting points.

In fact, after the end of the battle, the headquarters had already dispatched a group of people to carry out these things secretly, but Yang Zhen was still a little uneasy. The supply lines for this operation were too long, and the location of the battlefield was mostly in areas with extremely underdeveloped transportation.

If you don't make adequate preparations in advance, it will be too great to suffer unexpected losses. Moreover, the Japanese army's battlefield reconnaissance capability is quite strong, and the hoarding points of these materials and ammunition and the selection of field airfields, once they are not well deployed, it is easy for the Japanese army to leave a gap that can be exploited.

The most important thing is whether these locations are secret or not, which is not only related to the safety of these materials, but also related to whether the secret can be kept until the last moment before the battle starts, so as to achieve the maximum suddenness of the battle, which is also a key aspect of Yang Zhen's consideration. The delivery of large quantities of supplies and ammunition was bound to attract the attention of the Japanese army. If the concealment is not good, it is easy to alarm the Japanese army. Therefore, Yang Zhen had to take a look at it in person and inspect all the material delivery routes in detail.

It was not until December 2 that Yang Zhen, who secretly returned to Harbin, completed the investigation. But he didn't take any rest, and he didn't even have time to wash away the dust along the way. He immediately began to readjust and expand the troops on the basis of the plan already proposed by Li Yanping and Guo Bingxun.

As a result of the efforts of the Northeast Bureau and the Northeast People's Government, by the end of November, 150,000 additional soldiers had been provided to the anti-Japanese forces in the newly liberated areas. In addition to the 30,000 additional troops mobilized in the old base areas, although there is still a gap of nearly a quarter of the number of troops required, it is at least enough to meet the needs of the expansion of the main force.

As for the restoration and replenishment of the local armed forces under the subordinate military districts of the two levels, the time is not so urgent for the time being, and it can be slowed down a little. For the time being, it is still necessary to focus the expansion of troops on the main force first, and make final preparations for the upcoming second phase of the battle.

In addition to replenishing the casualties in the first stage, the Anti-Japanese Union used these recruits, and formed six new divisions and three independent brigades. Among them, except for the first to tenth divisions, only some recruits were replenished. The rest of the units were formed in a mixed manner with veterans leading the new, veterans and veteran units as the backbone, and new recruits as the backbone.

This mode of expansion not only ensures the expansion of the troops, but also prevents the combat effectiveness from declining too quickly because of too many new recruits. In order to improve the combat effectiveness of this group of recruits as much as possible before the launch of the 42 campaign. In accordance with the requirements of the Ministry of Resistance, in addition to two months of basic training, all of these recruits were pulled to the synthetic training base for comprehensive training.

Let the recruits, who have just completed two months of basic training, lie down in the trench and blow up the shells first, and then burn them with incendiary bombs, and then the tanks drive back and forth directly overhead. Even the training method of having recruits lined up in a row and lying between two tank marching columns less than five meters apart is probably something that only the Anti-United Nations can do.

Looking at the training method of the recruits of the Anti-Japanese Federation, the two veteran commanders were dumbfounded, and only then did they know what they called close to actual combat training. Not to mention how much material consumption is during training, even this cruel Cheng dù may not be able to do it with any army.

This is recruit training, not a veteran exercise. This kind of training is carried out among the recruits who have only completed two basic trainings, except for the Anti-Japanese Federation, I am afraid that no army in the world dares to play such a game. This is to let the recruits experience the cruelty of war on the training ground.

In fact, what the two veterans didn't know was that when they arrived at the comprehensive training ground, they had already entered the comprehensive training stage. The real basic training begins with the basic tactical training after the new recruits have entered the unit and have completed a month of queue and housekeeping training, as well as basic tactical and physical training.

Before the recruits had time to familiarize themselves with the firearms, they were ordered to dig the trenches and crouch in the trenches, let the machine-gun bullets fire at the top of the trenches they were in, and at the same time detonate the explosives points planted within five meters of their positions to create the effect of artillery fire.

This kind of training, which does not hesitate to pay the cost of work, has certainly paid a considerable price. Those recruits who have not been on the battlefield, even if they have veterans as the backbone, it is impossible to face this kind of training method without any problems. By the time this group of recruits had completed their basic military training, they had suffered more than 500 casualties in each stage of training alone.

But for the Anti-United Nations, this kind of price is also a really helpless thing. In just four months, it is too short a time for this group of recruits to complete the transformation from a peasant to a qualified soldier. Training that is close to actual combat is not interspersed as much as possible in training, so that recruits can experience the actual situation on the battlefield on the training ground. When it comes to the battlefield, the price paid by this group of recruits can only be greater.

As soon as these recruits leave the army, they are faced with a fierce battle, leaving them with little time to adjust. If we do not adopt training methods close to actual combat for these recruits as much as possible, I am afraid that after a battle, it would be good if half of these recruits could be left.

And this kind of high price is exactly what the Anti-Union cannot afford. Therefore, Yang Zhencai personally formulated this training plan, in addition to accelerating the maturity of these recruits and shortening the process of recruits' growth, in order to improve the psychological endurance of recruits on the battlefield.

Although this seems somewhat cruel, it is also a helpless choice. The new recruits who replenished the troops this time accounted for almost one-third of the total number of troops. And the full combat calculation is only four months of training at most, and they can't really understand what war is.

Once these recruits arrive on the battlefield and have a psychological breakdown, it is likely to have a decisive impact on the outcome of the battle. One can sweep away ten, and ten can sweep away a hundred. In the face of a brutal war, neither strong military discipline nor ideological work can compare with the desire for life. Although this kind of training seems a little cruel, it undoubtedly accelerates the growth of this group of recruits in advance.

There is no way, the time left for the preparation of the Anti-Union is too tight. According to the calculation of time, it is simply impossible to adopt the method of last year, after completing the training, pulling them to the confrontation zone with the Japanese army, and using a small-scale round battle to let these recruits accept what is called a real battlefield.

In fact, after completing basic training, a recruit faces many problems on the battlefield not tactical problems, but psychological problems. Tactical problems are easy to solve, but psychological fear is the most difficult to solve. The shells that constantly explode around you, the countless bullets that hit you, and the bloody corpses of your fallen comrades around you will cause the psychological breakdown of the recruits who are going to the battlefield for the first time.

Veterans know how to protect themselves on the battlefield, they are familiar with war, and they are used to seeing life and death, so there will naturally be no problems with their psychological state. However, these recruits who have not experienced actual combat, no matter how good they are in the training ground, are facing a rain of bullets on the battlefield, and it is difficult to control their fears.

Under psychological fear, no matter how good the tactics are, they will be completely lost. Let them feel the actual situation on the battlefield on the training ground in advance, and it will be beneficial for them to overcome psychological obstacles. Only by overcoming psychological obstacles and fears can this group of recruits truly mature and be used to put into the battlefield.

While the main force was expanding and adjusting its strength and was busy training new recruits, Yang Zhen also made certain adjustments to the weapons and equipment of various units in accordance with the experience of the first phase of operations. The original battalion 57-mm recoilless gun platoon was withdrawn from the troops, and all of them were replaced with new 82-mm recoilless guns.

Although the 57-mm recoilless gun is mobile and flexible, it can also partially replace the original small-caliber anti-aircraft gun. However, after the battle, the general reaction of the troops was that when dealing with the Japanese army's permanent fortifications, the power of long-range shooting was still a little too small, and the range was a little too close.

In addition to the agreements reached with the Soviets, the amount that the Anti-Union needed to provide to the Soviet side was very large. In the case that this kind of artillery has been discontinued, and Yang Zhen does not want to reopen the production line. The 57-mm recoilless guns were all withdrawn from the front-line troops, and the whole army was uniformly converted into the 82 recoilless guns in stock.

In addition to the 57-mm recoilless gun, the 12-mm high-level dual-purpose machine guns of each infantry battalion were increased by two. The original general-purpose machine guns of the company were all issued to each infantry platoon. For each infantry platoon, the number increased to three.

The original divisional artillery regiment, except for the newly formed division, which was still using Japanese-style 95 field artillery due to insufficient numbers. The field artillery battalion of the divisional artillery regiment of the old unit was disarmed with all the Japanese-style 38-type field guns and the Polish-made 1897-type field guns, and converted them into 76-mm cannons delivered by the Soviet Union.

As for the part of the M30 122-mm howitzers exchanged by the Soviet side, Yang Zhen did not hand them over to the divisional artillery regiment. Instead, this batch of howitzers replaced the 100-mm Polish-made Austro-Hungarian howitzers in the artillery belonging to the column and the artillery directly under it.

The 100-mm howitzers that were replaced were selected to be usable, adding a part of the strength of each divisional artillery regiment. The Type 38 field guns and Polish-made French field guns, which were replaced by Soviet-made artillery, were all airlifted to the Kannai battlefield in addition to supplementing the advance army and leaving some of them as reserves.

The British accompanied the two-pounder guns that the tanks forwarded, and Yang Zhen gave all the troops, including the Advance Army, a six-gun company for each infantry regiment. As a regimental direct firepower, it was used to deal with Japanese lightly armored targets and civil engineering fortifications.

This batch of two-pounder guns, although it has fallen behind in North Africa and the Soviet-German battlefield. But in the Asian theater, there was no problem dealing with the tanks of the Japanese army, as well as civil fortifications. The most important two-pounder gun is very light, and it can still play a considerable role in mountain warfare.
