Chapter 49 Liu Xiu’s Special Operations Squad
  Then Liu Qin began to explain the origin of the radio station.

After Liu Xiu heard his cheap dad explain the principles of radio stations, he compared it with the knowledge he had gained before traveling through his mind and found that there was no difference!
  So Liu Xiu immediately said to Liu Qin:

"Dad, what you mean is that the signal is strongest when the receiving antenna of the radio station is parallel to the radio wave band. In this way, the transmitting direction of the radio station can be determined, and then there is another receiving antenna, using their position and angle. If the difference is different, we can roughly determine the specific location of the radio wave emitted by the radio station!"

"Yes! You can use this principle to determine the specific location of the radio station's transmission!"

After Liu Xiu received Liu Qin's affirmative reply, he went back to the Independent Regiment without staying in the county.

In fact, Liu Xiu knew about the positioning of radio stations, but because Liu Xiu's own time-travel identity is here, he is just a teenager, how could he know so much knowledge!
  If Liu Xiu's identity was like that of his cheap father, who was an overseas student who had returned from studying abroad, then it would be reasonable to do anything, and even if he came up with mushroom bombs in the future, he wouldn't be surprised!
  It is precisely because of this that Liu Xiucai came to the county to find his father, Liu Qin, who had studied abroad. This way, when asked, Liu Xiu could easily answer that his father, who had studied abroad, told him.

As soon as Liu Xiu returned to the Independent Regiment, he immediately found Zhao Gang and said to Zhao Gang:

"Zhao Zhengwei, I just went to the county to ask my dad. My dad also told me about radio. He told me that radio positioning is actually possible because when the radio's receiving antenna is parallel to the electromagnetic wave, the received The received signal will be the largest! If there are more than two receiving antennas with different positions, you can use the angle they see to determine the location of the transmitting station!"

"Liu Xiu! The information you provided is very important. I will report it to the commander immediately!"

After saying that, Zhao Gang went to the group's telephone room, and then told the commander what Liu Xiu said, and the commander naturally took it very seriously. Then he tested the radio and found that it was true. As Liu Xiu said, the location of the transmitting station can be determined through two receiving antennas at different locations.

After Liu Xiu knew that the commander of the Eighth Route Army paid attention to the news that the radio station could be located, Liu Xiu stopped paying attention to it. After all, he had to do everything he could to obey fate. There was nothing he could do about Liu Xiu's tragedy.

After all, although Liu Xiu is said to be a time traveler, he can't turn the tide even if the system doesn't support him. How can one person change the outcome of a war and drive away the Japs in advance?

The next period of time can be regarded as a relatively peaceful period of development in the Eighth Route Army, because during the next period of time, the little devils are busy causing trouble to the United States!
  For example, just this year, in December 1941, the Japs launched the Pearl Island Incident without declaring war. It was precisely because of this incident that the United States finally had an excuse to join the war.

As a time traveler, Liu Xiu was naturally very happy that the little devil did such a stupid thing. After all, although the population was large, without the participation of the United States, it would be impossible for an agricultural country like this to compete with an industrial country like the little devil. If we go head-to-head, we don’t know how many people will die!
  After all, the gap in technology sometimes has to be filled with human lives. Of course, when the gap in technology is not large enough, it can also be made up by using factors such as number of people and morale.

········
  "Quick! Quick! Quick! Get in from here!"

Following the command of Liu Xiu, the battalion commander, a group of people wearing helmets and bullet-proof steel plates filed into the barbed wire fence that Liu Xiu had just cut and approached the Japs' bunker!
  That's right, after Liu Xiu added up all the credits related to the location of the radio station and the last time he defended the Eighth Route Command in Chenjiayu, his superiors finally changed him from company commander to battalion commander. Of course, he was not the first battalion, the main battalion of the independent regiment. The battalion commander, but the battalion commander of the second battalion. After all, it happened that Shen Quan, the commander of the second battalion, was shot with several rounds of bullets by the Japanese Special Forces with a submachine gun during the last defense battle of Chenjiayu. He died before he could be rescued. Therefore, Liu Xiu would naturally put the second battalion to death if Liu Xiu continued to perform meritorious service. The position of battalion commander was given to Liu Xiu.

And Liu Xiu just took advantage of the last battle in Chenjiayu and killed eight members of the Yamamoto Special Forces!
  At that time, Yamamoto evacuated in a hurry, and the corpses and equipment of the little Japanese were also left behind, so this naturally benefited the Second Battalion, which suffered the most casualties.

Not to mention the submachine gun in the hands of this little devil's special team, this helmet alone is a good thing. It is either stamped from chrome steel or molybdenum steel. Its hardness is much better than that of the little devil's iron helmet. Anyway, Pistol bullets and submachine gun bullets can't be penetrated. Even the kid's 38-meter rifle can't penetrate it. Such a helmet is comparable to a three-stage helmet.

So when Liu Xiu became the battalion commander of the second battalion, he naturally kept such good things for his own battalion. Then Liu Xiu selected a few veterans who were good at shooting and had good marksmanship, and gave these special bulletproof helmets to these veterans. , and then formed a special operations squad.

Of course, if you have a bulletproof helmet, you must also have a bulletproof vest, but in this era, I don’t know where Kevlar fiber bulletproof vests are!

Besides, even Kevlar body armor cannot protect against rifle bullets! If you want to protect against rifle bullets, you must be equipped with bulletproof inserts. For example, the mercenaries before Liu Xiu's time travel, or the soldiers on the battlefield who did not come with bulletproof helmets and bulletproof inserts as standard equipment.

While Kevlar body armor is difficult to obtain, bulletproof steel plates are also difficult to obtain!

It’s not easy for any blacksmith to make a one centimeter thick steel plate. Of course, this bulletproof insert is not big either. It is 25 centimeters wide and 30 centimeters long. It is enough to protect the chest. , and such a steel plate weighs only 5.8 kilograms and more than 11 kilograms.

Of course, this kind of weight is still a bit heavier compared to the modern ceramic bulletproof inserts, Kevlar bulletproof inserts, alumina bulletproof inserts, and silicon carbide bulletproof inserts. After all, these bulletproof inserts only weigh a little over two kilograms. About kilograms.

But compared with my own life, this weight is nothing!
  Liu Xiu took advantage of the darkness and moonlight at night and quietly approached the bunker with his special operations squad. Then Liu Xiu made a gesture, and then a special operations team member took out a melon grenade, that is, A little devil's grenade that has to be hit on the head to make it go off.

After smashing the grenade and waiting for about two seconds, the special operations team member threw the grenade into the firing port.

After the grenade exploded, Liu Xiu also kicked open the wooden door of the bunker, and the wooden bolt as thick as his arm was broken by Liu Xiu.
