The German submachine gun that appeared at the same time was also suppressed by the Winchester M1897 in terms of firepower, and as a result, the strategic advantage of the submachine gun was not fully revealed, and the first war was already over. As a result, the nascent submachine gun did not have a comprehensive impact on the way the infantry fought at that time on the battlefield of World War I.

Why did Yang Tianfeng make a shotgun? This was inseparable from the situation of China's resistance to Japan at that time. Whether it is the Nationalist Army, the Eighth Route Army, or the New Fourth Army, it is an undeniable fact that the training and practice time of soldiers is short and the quality is low.

Relying on a few or a dozen live ammunition shots, of course, you can't train many sharpshooters. And the standard of sharpshooters at that time, being able to accurately hit the enemy from a distance of 200 meters is well deserved.

In this case, even if you are holding a rifle in your hand, the effective range is up to hundreds of meters, and for most Chinese soldiers, you can only have a relatively high hit rate against the enemy within 100 meters. This means that in the battle with the Japanese army, the Chinese* officers often had to release the enemy within 100 meters, or even 50 meters, before ordering the soldiers to shoot.

Because shooting far away is basically a waste of bullets and adding courage. Even in the Nationalist Army, each soldier carries only twenty or thirty rounds of ammunition, while the Eighth Route Army and the New Fourth Army usually carry single digits.

To sum up, Yang Tianfeng has his own understanding. Whether it's right or wrong, but he's really thinking, he's really thinking about it.

Since the quality of the soldiers is low, the ammunition itself is also small, and the combat casualties are more than 100 meters, is the ****** more powerful than the rifle? Especially in defensive operations, such as trench warfare, the destructive effect of shotguns is certain. Otherwise, there would be no "trench broomstick".

Of course, Yang Tianfeng does not want to transform his troops into a melee army with shotguns in hand, but hopes that even recruits who have been training for a few days can use ****** to "bomb" devils, instead of shooting devils.

In Yang Tianfeng's view, starting a field battle with devils is purely looking for death, at least in a few years, there is no need to think about it. In a long stage, defensive battles, mountain battles, ambush battles, close combat, night battles, etc., will be inevitable. And the manpower advantage is one of the easiest to use and think of.

“…… This is a bayonet mount, which can be equipped with a special bayonet to fight the enemy hand-to-hand. Yang Tianfeng stretched out the design of the shotgun with a long barrel and made a final explanation: "In the future, other guns will also be equipped with bayonets, and this triangular shape will be produced." You don't need to be a swordman, it's like a spearhead. ”

The three-edged bayonet can not only increase the lethality (it is generally a square hole, and the wound can not be squeezed on each other to achieve a certain hemostasis and healing effect, and this wound is not easy to do the initial emergency treatment), but also the material requirements are lower than the bayonet that can chop and split, which is convenient for production.

Chen Sanhu understood that the shooting method of this ****** was similar to the large lifting rod used in the Qing Dynasty, and it should belong to the kind of one dozen and a large area, but the reload was faster and the gun was lighter. But he still needs to take it back and study it, and he still needs to ponder and experiment.

"Young Master-" Chen Sanhu hesitated for a moment, and said with a wry smile: "According to your instructions, the machine is being re-debugged and repaired, and the matter of re-recruiting technicians has been arranged, and the old people who worked in the factory before should be able to recruit a lot." However, you also know what is the biggest difficulty of the current gun factory? ”

Yang Tianfeng nodded and said, "I know, it's a matter of raw materials." Well, I've figured it out, and the difficulties will be solved. You start manufacturing with stockpiles first! ”

Whether it is Bei Tingfang's Houzhai Gun Factory or Yang's Small Arsenal, neither can solve the problem of raw materials for making guns. In the past, the steel needed was imported from abroad and shipped from Shanghai and Hankow. In addition, the copper used to make bullet shells and the gunpowder used for filling them are difficult to be self-sufficient. That's the biggest constraint, the cost is high, the output is limited, and there are many uncertainties.

For Yang Tianfeng, who has too much information in his head and is worried about the explosion if he doesn't take it out, this is not an difficult problem to solve. But it does take time to gather raw materials, improve equipment and production processes.

In addition to the shotgun, Yang Tianfeng also took out other drawings, one of which was a practical weapon - landmines.

As an easy-to-manufacture, cheap and efficient weapon, Yang Tianfeng still prefers landmines. Moreover, the mine design drawings he took out were relatively advanced, including anti-infantry mines, anti-tank mines, and jumping mines. Anti-infantry mines include ordinary explosive mines, stick mines, and directional fragmentation mines.

"A few of them are relatively simple and easy to manufacture." After listening to the explanation, Chen Sanhu already knew that as an old engineer who has been engaged in military production for more than ten years, mines are obviously much easier than shotguns.

Next, Yang Tianfeng and Chen Sanhu discussed and studied the new plan of the gun factory, the division of labor and cooperation in the workshop, the process improvement of iron-making and forged steel, and the manufacture of glass from crucibles. In the end, Chen Sanhu received another 3,000 oceans of capital investment, and said goodbye with a smile.

Military production has a long way to go! Yang Tianfeng's face was not happy, compared to the knowledge he mastered, the manufacturing capacity of the gun factory really made him anxious. But this is also a matter of no choice, it can only be gradually accumulated, gradually expanded, and gradually improved.

………………

The moon had risen, and the night had turned pale and black. The shadows seemed to disperse, and the air was transparent, fresh, and warm, and I could see it everywhere, even the grass stalks on the side of the road.

In the old house of the Yang family, a few "dead wind" lamps were lit and gently swayed on the high wooden stakes. Compared with Yangjiazi, the old house is much smaller and cramped, and many people have to live together. But for the nursing home, it is a lot easier.

Yang Tianfeng walked into the inner courtyard, the main room was empty for the old lady to live in, he and Meng Qiulan lived in the east room, and Zhao Yurou and the two little girls lived in the west room. The lights on a lamppost were jumping, and as long as he bypassed the lamppost, he would reach the intersection of the road, turn left, and he could go back to the house.

Under the dancing lights, a white scarf was fluttering. Yang Tianfeng stopped. Ears with short hair, combed with handsome "bangs", and under the apricot yellow sweater is a Yin Dan Shilin cloth cheongsam. Tight-fitting sweaters are not buttoned, and they show off the curvaceous beauty of the body. Zhao Yurou's breasts are plump, making the lines of her side more and more attractive.

Zhao Yurou turned her face and took a look at Yang Tianfeng. Yang Tianfeng was stunned for a moment, and then smiled: "It's you, your hair cut?" ”

"Hmm!" Zhao Yurou responded, as if it was a sound made by his nose, turned around and walked towards the west wing, but slowly stopped, turned around and said to Yang Tianfeng: "Hey, you stop." ”
