Traveling through the sword to engage in military industry.

Chapter 118: Everyone has a rangefinder, and everyone is a great gunner
"Distance-finding instrument?" Ren Zhong did not rush to answer when he heard the request from Yangcun. He seemed to have seen it in the main plane, but he did not usually think about the military use of these civilian products.

Just like the telescope, if Ren Zhong didn't need to bring it with him, he wouldn't have realized how rare this thing was in the world of Bright Sword.

So he took seven or eight of them later to solve the need for the telescopes of the general, the division commander, the brigade commander, Li Yunlong and other people close to him. After all, the 12x modern telescope is much better than the 6x telescope they captured.

Back to the main plane, as expected, Ren Zhong found many brands of laser rangefinders on the Internet. Within a range of 1000 meters, the accuracy can reach 0.5 meters, and there is also angle difference. With this thing, Wang Chengzhu's thumb distance measurement method suddenly became unusable.

When Wang Chengzhu from Yangcun received the goods and read the instruction manual rewritten by Ren Zhong, he was silent for a long time.

However, after Zhuzi completed the test and test-fired the grenade launcher by looking at the instruction manual, facing a hit rate of over 80%, Zhuzi quickly abandoned the thumb ranging method that he had planned to pass down from his ancestors and began to fully embrace the new era.

The precise measurement of distance and angle deviation allowed Zhuzi to shift the focus of his teaching to the calculation of adjusting the launching angle of the grenade launcher. Based on his experience, he compiled a jingle similar to the multiplication table. There is a catchy jingle for how to shoot at 300 meters and how to shoot at 500 meters. He doesn't need his apprentices, who cannot even recognize all the names, to start from scratch.

There is no theoretical knowledge such as parabola and initial velocity to be taught. From 100 meters to 500 meters, you just need to adjust the angle according to the formula.

A grenade launcher team consists of two people, one person measures the distance and observes the landing point, and the other person operates and corrects. With the help of Yangcun's relatively abundant grenade launcher grenades, practical exercises are carried out. Now it takes less than a week to train a group of qualified grenade launchers - according to the current graduation standards, the first-shot hit rate out of 10 targets must be more than 6.

Li Yunlong didn't expect that Ren Zhong could really solve his problem. This thing fell into his hands. After a brief training from Zhuzi, Lao Li and Kong Jie practiced together and actually obtained the qualification to graduate as a grenade thrower.

If the current grenade launcher grenades were not limited, Old Li would have wanted to train all the main companies of the independent regiment in grenade launcher operations. Just know how disgusting this thing is when facing the Japanese attack on the battlefield. Li Yunlong and the others are so happy now.

With a laser rangefinder, a properly trained grenade thrower would most likely be able to suppress the Japanese grenade thrower even if he counterattacks from behind!

In this regard, technology is more powerful than magic. The Japanese want grenade throwers that require a lot of training to master, but the independent regiment can now mass-produce them in a short period of time!
Old Li was very happy, but Ren Zhong was uncomfortable, as there was another item that had to be met, making his choice of selling even more difficult.

However, Ren Zhong also gained something. It turned out that the sparrow warfare he talked about with Zhang Dabiao only consisted of rifles, grenades and mines, most of which were short-range attacks. Although they were effective, they might not be able to take effect quickly.

But now that we have a simple method to operate grenade launchers, the lethality and attack range of the Sparrow War have expanded dramatically, and the threat factor to the Japanese and puppet troops has increased by orders of magnitude.

You should know that although the grenade from a grenade launcher is not as lethal as a mortar shell, it is still a terrifying heavy weapon that combines point and surface lethality. A grenade falling into a crowd and exploding can at least kill several Japanese soldiers and puppet troops. Even if they don't kill them on the spot, they will be crippled.

The grenades made of high-quality gray cast iron in Yangcun are no less lethal than those of the Japanese. When used with high-quality explosives, they can kill people within a radius of several meters after they explode.

Moreover, the combat attack range can be expanded to 500 meters away, and the safety of the Sparrow combat team using grenade attacks can also be greatly improved!
This kind of attack from hundreds of meters away and then quickly leaving the battlefield made it even more difficult for the Japanese to defend themselves.

Soon, all the armed work teams in Heyuan added a group of grenade throwers from Yangcun, and the imitation of the 71-type medium-range radio began to be delivered. With this thing, the base outside Heyuan City will soon be able to form a complete information network, and the actions of the little devils will never be missed.

But this was not enough. The tragedy in Dabeigou made Ren Zhong realize that even if the Japanese were defeated outside the city and did not dare to come out to rebuild their strongholds, they still had a huge advantage in the city. They dispatched squadron-level teams along the highways and roads, and Heyuan lacked the power to compete in the short term. Therefore, Ren Zhong assigned all the newly developed 82mm mortars and 56 newly processed 20 semi-automatic mortars to Zhang Dabiao, and asked Zhang Dabiao to select elite troops to form the first guerrilla brigade in Heyuan, which was initially organized into a company, an 82mm mortar squad, a grenade squad with 3 grenade launchers, 3 standard infantry platoons and 9 infantry squads, and each squad leader and deputy squad leader were equipped with 56 semi-automatic mortars. Each platoon was equipped with a crooked handle sub-machine gun.

This is a configuration that Ren Zhong tailored for Zhang Dabiao. It is designed to be able to restrain the opponent when fighting a positional battle when encountering squadron-level Japanese invaders.

Since laser rangefinders are very scarce, each squad of the armed work team needs to configure an independent one to facilitate the implementation of the sparrow warfare. The grenade launcher squad of the guerrilla brigade can only share one of the three grenade launchers. Considering the range of the current improved grenade launchers, sharing laser rangefinders is not a big problem and can control the main firepower points of the Japanese.

Mortars, as weapons of mass destruction, were deployed at a distance to carry out position-covering strikes. Even if the Heyuan devils sent out the most powerful Type 92 infantry artillery squad, they would still be able to fight.

If Ren Zhong had not been in Heyuan, Zhang Dabiao would definitely not have been able to obtain these weapons and equipment.

Grenade launchers are fine, given current production capacity, three grenade launchers per company will soon become standard. If a company is not assigned a laser rangefinder, the grenade launchers will be decentralized to the platoon level for use.

If laser rangefinders are distributed, it will undoubtedly be more effective to use them in a centralized manner.

It is impossible for a company-level guerrilla brigade to be equipped with weapons like the 56 semi-automatic and 82mm mortars, let alone equip the squad leader and deputy squad leader.

According to the production capacity of 80 82mm mortars, this was prepared for the main regiment and battalion level before the counterattack. Each battalion was equipped with two mortars as standard. This was targeted at the Japanese infantry battalion and was specifically aimed at the artillery squad of the Japanese infantry battalion.

If there were no heavy responsibility, there would be no idea of ​​blocking the Japanese battalion at the battalion level. Under normal circumstances, at least one main regiment would be needed. But now that there are 1 more 80mm mortars, the brigade commander and his men have become even more wild. They are considering using one battalion to block one battalion and concentrating 82 to 3 battalions to eat up another battalion.

Because the Japanese had not suffered a major blow yet, basically the battalion-level troops dared to run rampant in the base. In Ren Zhong's time and space, at this stage, battalions like the Yamazaki Battalion actually went deep into the core area of ​​the base's arsenal alone. Of course, Ren Zhong has not heard of such a thing yet.

He didn't care at all about how the brigade commander and his men planned, and just focused on building his new base. The priority this time was to solve the copper smelting problem. After all, relying on transporting copper coins was increasingly wasting transportation capacity.

Although China in the main plane has solved the problem of steel bullets, Ren Zhong has not found the specific process information. Relying on some half-baked instructions, the steel bullets that Ren Zhong asked Yang Cun to trial-produce have many problems. Not only are they easy to wear out the barrel and affect the life of the gun, but they also greatly increase the chance of bullet jams, which is intolerable and is often fatal on the battlefield.

The solution is said to be to plate a layer of brass, which not only reduces manufacturing costs but also solves the friction problem between the cartridge case and the barrel. However, the copper plating process is completely unknown, and the problem is not dared to be handed over to domestic personnel to solve.

This is no longer scientific research, it is illegal.
