The need for rapid-fire weapons on the Eastern Front and even for the entire six countries was not very large. There are many reasons for this. In general, the national strength is not as rich as that of Qin.

The price of a smokeless powder bullet is around eighty cents. If bullets are in short supply. Then the price is likely to soar to one shot and one and a half taels. One shot does not hit the warhead. It's money. The Six Nations did not have that country that had it and produced it like the Qin State. And there is such a complete industrial system.

Weapons production in the Qin State began day and night. It's not just the needs of the six countries. There are also huge military orders. Especially in terms of firearms manufacturing. More than 300 million rounds of 35-caliber ammunition were ordered for smokeless gunpowder ammunition. The order of this batch of guns and ammunition means that the Qin State officially replaced the original black powder guns with smokeless powder bullets.

It was accompanied by a large production of machine guns. The advent of automatic, semi-automatic weapons. Let the demand for bullets rise dramatically. Especially machine guns. The northern part of the Qin state was heavily armed with various machine guns. The long experience of war tells the Qin army. Machine guns are the best weapon against the northern nomads. This automatic weapon, capable of firing 400 to 500 rounds a minute, can effectively break up the Huns' cluster charges.

For this. The machine guns of the Qin State developed unusually rapidly. In particular, various machine guns appeared one after another. This is the credit of the Qin State Science Patent Office. Within a year, the Qin Patent Office issued hefty fines for several commercial cases of patent infringement. The most typical is the "D" type car of the United Automobile Factory. The Patent Office considered that the interests of the joint manufacturing plant had been infringed and issued a hefty fine of 1 million gold to the six automobile manufacturers. In this way, the recurrence of patent infringement cases is deterred. In order to circumvent patents. Manufacturers almost all have to avoid patent barriers. Meantime. Major manufacturers have increased their scientific research efforts. Set up different degrees of technical patent barriers. Technical communication has been affected. But there is a great diversity of products. There are pros and cons. The state of Qin needed to make some improvements.

In this context. Machine gun designers need to circumvent the various technical patents of water-cooled machine guns. So all sorts of machine guns began to appear.

The water-cooled machine gun was unusually bulky. Often the infantry needed four men to move. Six people can form a machine-gun fire team. Cavalry units need to be fitted with small artillery wheels to maneuver quickly. Thereupon. Air-cooled machine guns are introduced.

The most important feature of the air-cooled machine gun is the use of heat sinks. The heat sink is mainly placed in the barrel and bolt position. The contact area with air is increased to achieve a cooling effect. In terms of bolt action, the air-conducting principle of the Hakas machine gun was adopted. As a result, the full weight of the machine gun was significantly reduced. But this machine gun was not massively transmitted. The reason is that this machine gun makes the soldier feel very unsafe. Another machine gun was introduced. So that this machine gun did not have the need for its existence.

This machine gun is an air-cooled tube machine gun that uses hollow drilling. This machine gun is an extended and improved version of the Lilin-style water-cooled machine gun. The original tank was canceled. Air-cooled pipes are used. This air-cooled pipe is very convenient for processing. Punching holes in the external tube is sufficient. Although the rate of fire has decreased. But if a certain rate of fire is maintained. The firing time can be appropriately extended.

At the same time, in order to keep the barrel from being burned by bullets in time. The designers of the Lee Arsenal installed handles at the barrels of machine guns. Just open the jam. Rotate and pull out to replace the barrel in time. It's very convenient. This handle shot was supposed to be used to replace the barrel. But in actual combat, the tripod is often discarded. Hold the handle in your left hand. Pull the trigger with your right hand for horizontal strafing. Small machine guns can be used. Because of the hand used to pull the trigger. The larger ones are the pull triggers.

This is enough to see that the weight of the machine gun has been significantly reduced after the use of this machine gun. This machine gun to some extent played the role of a squad machine gun. But that's just a cameo.

A real squad machine gun was adopted by the Lieutenant of the State of Qin. The Wenyang Type 3 light machine gun was officially purchased and passed on to the troops. The order for machine guns attracted the attention of many weapons manufacturers in the Qin State. This is naturally indispensable to the Wenyang Arsenal. With its connections. and the earliest use of smokeless gunpowder bullets. Yingyu was the first to obtain the technical patent for smokeless gunpowder. This allowed her to get a huge military order of 200 million rounds of ammunition. She wasn't satisfied. It was thought that machine guns should also enter. But perhaps the competition for machine guns was too fierce. The arsenal designed two not very successful machine guns. The second model had to be scrapped due to its resemblance to the heatsink machine gun.

Lee's Arsenal snatched almost all orders for machine guns. The Qin army planned to massively transmit rapid-fire weapons. They equipped almost every division with more than a thousand machine guns. It's almost an upstart type of equipment weapon. But it's understandable when you think about it. Qin's opponents were all cold weapons. At the time of the group's charge. The speed advantage of rapid-fire weapons is the best weapon against them. There is another important reason. The combat units of the Qin army were often deployed in companies and platoons. In order to achieve superiority in firepower. It was necessary to massively popularize this semi-automatic, automatic machine gun. A company needs at least six machine guns.

Lee's air-cooled tube machine gun. The Qin State was officially numbered as a Type II machine gun. Although it is possible to use a machine gun on temporary duty. But his starting point was to fix the point of machine-gun fire. Not mobile. And. This strafing can only be demonstrative. Can't shoot rapidly. So under this demand. The Qin army demanded a light machine gun that could move quickly. This was the later Type 3 machine gun.

In order to obtain a military order for light machine guns, Wenyang Arsenal first acquired the patent for air-guided machine guns. Then, for the first time, a spiral heat sink design was used on the basis of air-cooled sheets. This circumvents the technical patents for air-cooled sheet design. At the same time, the weight of the machine gun was significantly reduced.

With both designs. For the first time, the Type III light machine gun was offered to the military. This machine gun is similar to a Czech light machine gun. The barrel is not removable. Feed with a chain. However, this type of ammunition feeding method often snaps the bullet chain during the test. Thereupon. The designers switched to a magazine-type feed from below. The magazine is twenty rounds. In this way, the gun is between a rifle and a machine gun. For the rifle he was heavier. For machine guns he was barely lighter. However, in order to reduce the burden on users. The Wenyang Arsenal made special use of fixed bipods. The fact is. This design is redundant. In actual combat, soldiers even dismantled the bipods. But in addition, his gun belt soldiers liked it. The gun belt is very ergonomic. The use of a triangular gun belt effectively broke down the weight of the machine gun. It can be easily controlled by attaching the hook on the machine gun with the hook. It's very convenient.
