Li Zongren and He Yingqin were Gu Zhutong, and Chen Cheng did not give this person free. Everyone has their own unique insights in military command. Chiang Kai-shek's so-called battle arrangement can be said to be not in a proper way, nor is it a surprise to win. The odd in a surprise to win is relatively risky, but adventure requires rich harvests and rewards. Chiang Kai-shek's plan seems to be only risky, and the harvest and reward are not great, because the material assistance of the Japanese North China and Central China did not come from North Korea and Northeast China, but was transported to Tianjin and Shanghai. There was not much cooperation between the Japanese North China Front Army and the Kwantung Army. The Kwantung Army was established in the general army and was at the same level as the chief agency of the North China Front Army's superiors. Therefore, the cooperation between the two previous battles required the Army Base Camp to coordinate, and the combat plan also had to be formulated and implemented by the Army General Staff Headquarters.

In this way, the effectiveness and effect of the so-called Kanto Army and the Japanese North China Front Army's combat plan will be very insignificant. At most, it can only restrain some of the Japanese North China Front Army's forces. Unless the Tenth War Zone can threaten Tianjin Port, the long coastline and numerous port cities of the Chinese Chamberlade country were all supply docks for the Japanese army that had absolute control of the sea.

While Chiang Kai-shek was busy putting his shoes on Zhang Xuewu, Zhang Xuewu was busy changing the Tiger Ben Division and the Honorary First Division in the 10th War Zone. The Baotou Military Factory has been developing and using semi-automatic rifles that use intermediate power ammunition according to Zhang Xuewu's requirements and orders.[]

Rifles are the most basic weapons used by individual infantry soldiers. According to different types of performance, rifles can perform different tactical tasks. The main function of rifles is to use their firepower, bayonets and butt stocks as strike methods to kill and kill living targets. Therefore, in close combat, the rifle plays an important role in solving the final stage of combat.

A semi-automatic rifle is a rifle that automatically loads and loads a bullet, also known as an automatic loading rifle. It does not need to be like a non-automatic rifle... For example, a spinning pulling bolt rifle, which is manually loaded. After each shot, the bolt needs to be pulled once to complete the shell and reload and load.

The semi-automatic grief gun uses part of the gunpowder gas recoil after the gunfire is fired to remove the shell, the bullet is automatically loaded and ready to fire again, but only one bullet can be fired at a time of pulling the trigger.

In fact, Zhang Xuewu wanted to target assault rifles such as A-4 that fired intermediate power ammunition. Because the firepower of a single manual rifle is far from meeting the tactical needs of each unit in the tenth war zone, and the ammunition consumption of automatic assault rifles is too large, the range of submachine guns is relatively close, and the accuracy is difficult to meet the precise firepower needs of the frontier troops of 100 meters, so Zhang Xuewu made technical reserves for semi-automatic rifles in advance.

The world's first semi-automatic rifle recognized in later history was a 65-~ automatic rifle designed and invented by Mexican general Mondragon. In that year, it was first officially equipped with the Mexican army to develop semi-automatic rifles... Zhang Xuewu purchased a large number of semi-automatic rifles from all over the world, such as the United States, Germany, Italy, France, Britain and even the Soviet Union, for research by researchers and engineers from the Baotou Ordnance Research Institute, and learned from them.

In Zhang Xuewu's opinion, there are only two or three excellent semi-automatic rifles in the world, including American bu-type Garland rifles, German tian...tun rifles, Soviet t-ma rifles and subsequent derivative models, famous Soviet gun designers Sergei, Gavriroviim Simono's CCS semi-automatic rifles, adopt the ordinary structure of the air-guiding automatic principle, and the air-guiding device has no gas regulator... The piston is pressed against the bolt frame through the push rod, and the piston's rear seat stroke is smaller than the machine frame stroke, so the automatic method of the gun belongs to the short stroke of the piston. The bolt deflection locking mechanism adopts a good degree, simple structure, easy production, and relatively good serviceability.

Compared with C semi-automatic rifles, it has been popular in the world for many years and can be regarded as a successful semi-automatic rifle in history. The gun can hold ten bullets at a time, with a scale range of one thousand meters. The actual shooting accuracy is quite accurate within 300 meters. It can meet the needs of the battlefield under any conditions and has excellent service adaptability.

The American... Garland rifle was named after its designer Kanter Us Garland, commonly known as its large eight-grain in the Cretaceous Kingdom.

The US military has always attached great importance to individual rifles fire. During World War I, the United States began to study automatic rifles. The ordinary field rifle bullets used at that time made the automatic rifle recoil when fired continuously, making it difficult to control accuracy... and it is heavy and difficult to carry.

The rifle purchased by Zhang Xuewu from the United States seems to be different from the formal large-scale installation of the US military in later generations? There seems to be an air shield at the front of the muzzle? After many shooting tests, it was discovered... This is from the so-called design that when firing, some gunpowder gas will enter the piston barrel through the gap between the end face of the barrel and the muzzle mask, pushing the piston to move backwards.

The disadvantage of this and the air conduction method is that it directly leads to the insolid connection between the piston cylinder and the mask, the unstable assembly of the bayonet, and the impact of the accuracy of the sight movement in all semi-automatic rifles..." The rifle ammunition supply method is quite distinctive. The steel magazine loaded with two rows of eight rounds of bullets is pressed into the magazine chamber from above the receiver. When the last bullet is shot, the gun opportunity is in an empty room and the magazine will be automatically ejected from the magazine chamber by the clip withdrawal device, which will make a crisp sound, reminding the soldiers to reinstall the phone.

The magazine has two double round upper and lower openings and single openings. The magazine with double round openings can be loaded into the magazine case regardless of whether it is up or down. The single opening can only be loaded upward into the magazine case. When loading, you must pay attention to the bottom of each bullet against the rear wall of the magazine leakage clamp. The pulling groove at the bottom of the shell snaps into the inner ribs of the leak clamp. If a bullet head extends out, other bullets cannot be loaded. Because the bullet clamp is exposed, sometimes the bullet may not be aligned.

In order to align the bullets. When the bullets are loaded, US soldiers often knock on the steel helmets a few times to align them. When the magazines pressed into the magazines at a time, they cannot reload the magazines again before the bullets are exhausted. If a single shot is loaded, the recoil of the bullets will often cut off the soldiers' fingers at the mouth of the barrel. It is extremely dangerous as a semi-automatic rifle..." The magazine capacity of the Galand semi-automatic rifle is still a little small.

Compared with the Americans' bu-type Garland rifles, the Germans' G... also rifles, Soviets' semi-automatic rifles, Zhang Xuewu's first feeling is that the gun body is too large and heavy, and the designed butt stock, front guard, and gun body are not in line with the physique and habits of most Asians. Each and successful weapon is extremely targeted. Tactical performance and service performance are the key to testing whether a rifle is designed reasonably and successfully.

What Zhang Xuewu needed was a semi-automatic rifle that could be suitable for the Chinese people, with an open-type ammunition compartment with no less than ten rounds of ammunition loading. It was based on the Soviet SKS automatic rifle, and borrowed from the Kayi-style decomposition and combination device of the semi-automatic rifle. The front end of the rifle was equipped with a folding triangular bayonet, and the weight after loading should not exceed 3.6 kilograms. The overall gun body should be produced and maintained, suitable for use under various conditions, and adapted to wind and sand areas, especially cold areas, with high serviceability.

According to Zhang Xuewu's various requirements, the final Chinese-type semi-automatic rifle was designed. The gun was 1,022 mm in length, the total gun mass was 3.52 kilograms, the barrel Vulcan axis was 522 mm long, four right-hand rifles, ten open ammunition compartments, the theoretical combat rate of fire was 30 to 35 rounds per minute, the effective range was 400 meters, and the scale range was 1,000 meters.

In terms of bayonets, Zhang Xuewu enthusiastically chose the Triangle Bayonet, a killer weapon for Hiroshi himself. In practical applications, the saber must first have sufficient lethality. In addition to weight, center of gravity, curve, and sharpness, what is particularly important is the severity of the wound and the difficulty of pulling it out after puncture.

Hiro himself was also made by referring to the style of his samurai sword. Any saber is designed with different designs and details to achieve the same purpose. Therefore, most sabers are narrow in front and wide in the back, and blood grooves on the side of the blade. Later generations added special high-strength serrations at the root of the blade according to different uses.

However, Zhang Xuewu did not have so much high-quality steel to make a big deal about sabers and bayonets, so the triangular bayonet became Zhang Xuewu's only choice. The forging process of the triangular bayonet is relatively simple, and its functions are very easy to meet tactical needs. In addition to bleeding, the three semi-arc blood grooves on it are more important to help soldiers perform their next actions.

Because after the triangular bayonet enters the human body, blood will be discharged quickly with the blood tank. The human body muscles contract or the bones cannot be clamped against the edge of the bayonet without sucking the bayonet or jamming the bayonet. In this way, the bayonet can be pulled out from the enemy's body chalk for the next step. After the bayonet is inserted into the human body, the empty beggar will be quickly inserted through the blood tank, and the air forms a large amount of foam in the body chalk, blocking blood vessels.

Ruxing has no blood grooves, because blood pressure and muscles contract violently, the bayonet may be wrapped in the human body. In this way, it will be very difficult to pull out the bayonet, which will affect the soldier's next move.

Moreover, the wound of the triangular bayonet is basically a large square hole. The wound cannot squeeze each other to achieve certain bleeding and healing effects, which will cause the injured to die in a very short period of time. When testing this and the new bayonet, many people are extremely surprised! Even worried that it will be condemned by humanity?

In Zhang Xuewu's opinion, using this has nothing to do with being inhumane, and this is simply a matter of worrying about eating carrots. The process of war is to kill and injure the enemy as much as possible in the shortest time. War itself has nothing to do with humanity. The person who insists on talking about it is just talking about it!
