PS: Thank you for the monthly ticket voted by the book friend "Old Man Li", and by the way, I asked for a recommendation vote ^_^

As a result, the Japanese army's first use of new tactics received miraculous results, coupled with the fact that the devils had learned a little bit about the advanced fortifications built by the 15th Group Army in previous battles, and as a result, the lethality of the 15th Group Army's long-range artillery was reduced to about 20% of the original, and the Japanese army's heavy artillery because of the specially designed slipway that could quickly transfer positions after the shelling ended, the survival rate increased countless times. If it weren't for the fact that the industrial base and scientific and technological conditions are too far apart, Hu Weidong really wanted to order the counter-artillery radar to tackle key problems, although his humanoid counter-artillery radar is awesome, even if the organization and superiors allow him to personally operate the artillery, it is impossible for one person's liliang to have much impact in the operation of a large corps

However, as the saying goes, "there are gains and losses." Although the Japanese Army's tactical reform greatly reduced the enemy's artillery fire and automatic weapons on its officers and men, it also led to a great dispersion of the devil's troops, which naturally affected the Japanese Army's ability to kill and injure the enemy. The 15th Army made up for this by equipping itself with a large number of automatic weapons and artillery (Note 1), while the Japanese army was seriously deficient in both of these areas, which was a terrible thing

Although Hu Weidong is still very young now, he has experienced a hundred battles, and he has guessed a little about this, and he knows very well that the tactics on Shijie are not actually the more advanced the better, and the suitability is the first, just take the PLA infantry squad platoon tactics that have been unique in the world during the Volunteer Army, if the enemy's firepower is not strong enough, its effect is even inferior to some old infantry tactics (queue shooting tactics later people look silly, but in the breech gun era it was the most reasonable tactic. ), and if your own firepower is also weak. The problem is even more serious.

Hu Weidong's speculation was verified by the Japanese offensive soon after, although the Japanese army invested more than 10 field divisions and more than 1,500 artillery pieces (not counting grenadiers) in the front of the attack, both of which set a new record in a single battle of the Japanese army since the war of resistance against Japan. But this seemingly massive offensive lasted less than a week before it failed completely. In the face of the canal defense line that the 15th Group Army rushed to repair during the period of prisoner exchange, the Japanese army suffered more than 100,000 casualties in such a short period of time, but did not form an effective breakthrough to any enemy position, and the 15th Group Army only suffered less than 10,000 casualties before driving back all the devils who crossed the river. After this battle of the canal. The Japanese army, which had been beaten out of the psychological barrier, no longer dared to launch a strong attack on the fortified positions of the 15th Group Army on the premise that air supremacy could not be guaranteed and artillery superiority was not guaranteed

However, it cannot be said that the new tactics of the Japanese army are useless, at least the ammunition consumption of the 15th Army has indeed increased significantly. Compared with the past, the amount of ammunition required to destroy an average of one devil has almost doubled (that is, it has increased to more than three times the original), considering that the Japanese army is using new tactics in actual combat for the first time, it is certainly not skilled enough, and it will inevitably be more difficult to kill devils in the future than it is now. In fact, in just such a short period of time, the 15th Army's ammunition reserves were reduced by almost half when it was not easy to replenish the time of exchanging prisoners, but the Japanese army acted as the attacking side. Naturally, the consumption of ammunition was greater, and coupled with the extremely disparity in the ratio of personnel exchange, it was the Japanese who were frightened by the sharp counterattack of the 15th Army who were the first to withdraw from the battle.

The reason why Hu Weidong was willing to smash out so much ammunition at once was that he was worried that the ammunition reserves would be consumed too much, and he knew the Japanese national character very well. Only when the enemy is frightened at once will the Japanese army completely abandon the idea of engaging in positional offensive and defensive warfare with the 15th Group Army and follow the haode script written by our side, and mobile warfare can always save ammunition than positional offensive and defensive warfare. Otherwise, if the Japanese army had been entangled with the 15th Army on the canal defense line, Japan's national strength and military production capacity would still be much stronger than China's (even if only the army and air force were counted, the Japanese army would still have the upper hand). ), coupled with the relative convenience of logistical supply (due to the loss of air supremacy in the Xuzhou area, the advantage of the Japanese army's logistical supply has been weakened, but it is still stronger than the 15th Group Army, whose logistics route needs to pass through the national control area and there is no railway connection in the middle section. If you fight for attrition, the 15th Group Army will still suffer a lot. Although the new tactics of the Japanese army have led to a sharp reduction in its infantry offensive capability, and the 15 th Group Army still has a strong defensive line to protect it, even without aircraft and artillery, the 15 th Group Army is still capable of repelling the Japanese attack, but with the rapid development of military production in the border areas, Hu Weidong has now begun to emphasize that "if you can solve the enemy with ammunition, you should not waste the lives of soldiers." "Here, if he had a choice, he still hoped that fewer people would die

The Japanese army in Xuzhou suffered losses more than once after losing air supremacy, and naturally wanted to recapture it as soon as possible, but during the period of exchanging prisoners, not only did the Soviet aid air force make up for the lost aircraft and personnel, but even the North China Air Corps was also affected by the first batch of I-16 fighters purchased from the Soviet Union (about 300 units, the second batch of 400 aircraft, and the third batch of 500 aircraft. In place and greatly strengthened. In the past month or so, not only have a number of field airports been built in the Shandong base area, but also regular airports in Lianyungang and other places that have been damaged to varying degrees in the war have also been repaired, and several airports are also being actively built (Hu Weidong's goal is that every city with a population of more than 100,000 people, or a city with a small population but an extremely important geographical location, should have a regular airport that can take off and land transport planes and other large aircraft)

Note 1: In fact, the People's Liberation Army is the same, even as early as the Red Army, it placed great emphasis on the development and concentration of firepower, which can be seen from the fact that the Red Army concentrated a limited number of submachine guns, machine guns and artillery for use. Historically, when it came to the time of the self-defense counterattack against Vietnam, the PLA relied on the absolute superiority in the number of artillery to bombard the Vietnamese army indiscriminately, usually in the context of the division's attack, the fire intensity of the breakthrough of the sharp knife company (you read that right, it is a company but not a regiment or battalion) is half an hour in the fortified area of about one square kilometer and the enemy's artillery and command area to carry out two to three fire preparations, projecting 7 to 80,000 rounds of shells, nearly half of which are 130~154 mm caliber shells (to be continued). )
