Even Hu Weidong was a little scared when he knew, "Fortunately, the luck is not too bad, if the devil has an armored army, or they will put the grille armor (a kind of external light armor, which has a miraculous effect on the bazooka of the principle of shaped energy armor piercing, and there is almost no jishu content, in fact, it is a strengthened version of barbed wire, and the only price after the tank is installed is only to increase the weight by less than 5%, and the probability of its effective destruction by the bazooka will be reduced to less than 4% when it is not installed) also get out, There is a real possibility that this battle will capsize in the gutter."

"After all, the tank is an offensive weapon, and it naturally has an advantage in the battle between spear and shield, and even a little trick can make a major breakthrough in anti-tank weapons or tactics worthless, but unfortunately we have too few tanks to use tanks to fight tanks, so we can only take other methods. Judging from the two recent large-scale antitank operations, it is not enough for antitanks to rely on bazookas alone, and if they want to resist the torrent of armor that exceeds 1,000, they must form a three-dimensional antitank combat system with aircraft, long-range artillery groups, antitank guns, individual antitank weapons, and a certain number of tanks or tank destroyers." Although Hu Weidong was not a first-hand witness to this campaign, because his understanding of various advanced weapons and tactics far surpassed that of this era, the summary he wrote as a bystander was highly praised by the chairmanAs a result, Hu Weidong's image as a "weapons expert" has become more and more deeply rooted in the hearts of the people.

The bosses of the Eighth Route Army were naturally very dissatisfied, but the commander of the Japanese 11th Army, Okamura Ninji, was even more incredulous when he found out about it. The most powerful weapons are given priority to the best troops, so in a sense, that tank division and two "mechanized" divisions can be said to be the most elite units in the Japanese Army at present, except for the Kwantung Army system. But such an elite ace army was completely annihilated by the Eighth Route Army, and the number of dead in the Eighth Route Army (about 20,000 people, offensive battles are generally more wounded and less dead. It was also much less than the Japanese army, which undoubtedly had a great psychological impact on Okamura Ninji

Even the Eighth Route Army has become so powerful now. So how powerful should the 15th Group Army, which is already China's strongest force, be now? Could it be that their previous terrible results of destroying 200,000 Japanese troops with one division were not just because the new weapons destroyed the psychology of the imperial officers and soldiers? The more Okamura Ninji thought about it, the more frightened he became, and it was from this that he began. Okamura Ninji, who originally thought that even if Japan could not swallow the great China, it would never surrender to the Chinese, felt a little frightened for the first time

In addition, Okamura was also very shocked by the ability of the Eighth Route Army's large corps to maneuver, especially since they seemed to know the movements of the Japanese army well, and the scheming Okamura couldn't help but wonder if the enemy had deciphered his telecommunications code again. In order to confirm his guess, Okamura Ninji did not hesitate to sacrifice a special division and deliberately let it be exposed to form a lone army, but as expected, he quickly fell into the encirclement of the absolute superior forces of the Eighth Route Army. Okamura immediately led the main force to retreat eastward, and at the same time reported his findings to the headquarters headquarters, pointing out that the purple cipher machine was likely to have a major flaw and had been discovered by the cryptographic experts of the Chinese Red Party.

Although Okamura's discovery may sound a little strange at first glance, due to the repeated fiascos during this period of time, the Japanese army headquarters still contacted the Germans who had provided the purple cipher machine to Japan. At this time, Germany was already more inclined to cooperate with China than with Japan. However, the natural rigor and seriousness of the Germanic peoples led them to study the issue carefully, and also gave the observers who remained in the Central Plains a certain degree of understanding, although only some clues were detected, but it was enough for the Germans to be sure that the Red Party must have indeed cracked the code generation law of the purple cipher machine.

Although the German telecommunications experts are conceited, but in the face of the facts they still bow their arrogant heads, in the psychological state of knowing that there are loopholes in the cipher machine, the German telecommunications experts are more serious and rigorous than usual, after a period of in-depth research, they finally found that the purple cipher machine and its prototype "Engnima cipher machine" although it seems to be very perfect, but once the codebook falls into the hands of the enemy, the enemy may be based on this kind of cipher machine to generate the law of the password reversed. Combined with the previous capture of Prince Takahito Mikasa, the Germans believe that the purple cipher machine is indeed very likely to be cracked by the Chinese. Although the Germans refused to admit that their products were not good, and attributed it to the Chinese mathematicians who were too powerful, they knew in their hearts that even China could crack it, not to mention that the United States and Britain were far superior to China in terms of experience and jishu in this regard.

Another flaw of the "Engnima cipher machine" has also been exposed, once the law of its generation of ciphers is mastered by the enemy, then this cipher machine is difficult to prevent the enemy from cracking no matter how it is modified. Realizing the huge risks involved, the mustache had to give up the "Engnima cipher machine" in favor of using artificially generated ciphers, which were difficult for the troops to master, and reiterated the principle that they should have adhered to the principle that no matter whether they were deciphered by the enemy or not, they had to replace the new cipher within a certain period of time, thus plugging this huge loophole, which inadvertently allowed Germany to avoid the joke that the code was deciphered by the British for a long time without them being aware of it.

Although this has affected the combat effectiveness of the German army to a certain extent, especially the difficulty of more complex tactical coordination such as air-ground coordination, Germany's stronger national strength, scientific and technological level, and more advanced weapons and equipment than the same period in history are more than enough to make up for it. Moreover, it was inconvenient to change the cipher before the war, but it was much better than the historical situation in which German radio communications remained one-way transparent until the end of the war, and they themselves did not know it

Note 1: The new cipher used by the Japanese army at this time was still from the purple cipher machine, and by the end of 1938 and the beginning of 1939, the frequency of the Japanese army's password change had increased to once a quarter, but with the Red Party cipher Jishu group's understanding of the principle of the purple cipher machine's generation of ciphers, the time required to decipher it has been shortened to half a month (to be continued). )
