Yang Tianfeng was also very depressed. His original idea was good, but later he thought that if it was transformed into a large-caliber sniper rifle, the recoil would be too amazing. Even if it was placed on a thick pad, it would still be unbearable. If it was transformed into a grenade launcher, it would seem quite difficult.

"This gun is good, but unfortunately the recoil is too high. I have some ideas, so I have to trouble Mr. Zheng. Let's make a silencer first."

Zheng Ran blinked and thought for a while, but did not dare to make a promise, but said with room for ease: "I'll try it! But it's not guaranteed."

"It's not to try, but it's definitely done well. Because--" Yang Tianfeng smiled, turned his fingers around, and said vaguely: "The drawings will be available soon. It's not difficult for Mr. Zheng to follow the drawings, and he can even create several in a day."

Drawings? Zheng and Sun were very confused, but Yang Tianfeng no longer mentioned it, but instead changed the topic and started talking about grenade launchers and heavy mortars.

At the end of World War II, the German army added a folding stock to the 27mm signal gun to fire small fixed-load grenades against the shoulder. In the early 1960s, the US military used the m79 40mm grenade launcher, which looked very similar to a hunting rifle, also known as a grenade gun.

From the perspective of manufacturing technology, grenade guns can adopt high and low pressure emission technology similar to grenade barrels, which not only allows gunpowder to be fully burned and the energy is better utilized; it can also make the pressure in the launch barrel lower, reduce production requirements, and even can be made of light metals to reduce weight.

Therefore, the difficulty of pulling out the technique lies in the manufacturing of fixed-load grenades, which requires relatively fine mechanical processing, but it is not a difficulty that cannot be solved and overcome.

Once the troops are equipped with such a lightweight, low recoil, can also shoot with shoulders, and curved and flat weapons, it will make up for the fire gap between grenades and mortars, and their combat power will be greatly improved.

In the anti-Japanese battlefield at that time, the Japanese army used a very wide range of infantry support weapons with a large amount of equipment, which was grenade launcher. Usually, each infantry squadron had a group of grenade launchers equipped with two grenade launchers. Each squadron was equipped with a total of six grenade launchers, with the same equipment as that of light machine guns. This shows the degree of importance the Japanese army attached to grenade launchers.

Because of its lightweight and good mobility, grenade launchers can always accompany Japanese troops to operate and provide firepower support at any time in various special geographical environments on the Chinese battlefield. The subsequent Pacific War also proved that grenade launchers are also suitable for jungle environments. Therefore, in many cases, the Japanese army's dependence on grenade launchers' firepower is even stronger than that of light machine guns.

Although the Japanese grenade launcher is a very creative light infantry support weapon, it also has many shortcomings. First of all, its launch and adjust range operation is much more complicated than that of the mortar, and it relies more on the experience and level of the operator. Moreover, the combat rate of fire is generally not as good as that of the mortar, and its accuracy and power are inferior to that of the mortar.

On the other hand, the structure of grenade launchers is more complex than that of the same caliber mortar shell. Under wartime conditions, the cost-effectiveness ratio is higher than that of the latter, so the scope of use is not as wide as that of the latter. Therefore, few other countries use it except Japan and China.

In China's anti-Japanese battlefield, due to the limited technology and production level, it lacks the ability and ideas to innovate and transcend. The most common method is to develop similar weapons based on Japanese weapons to achieve the goal of "treating others with the way of others."

Because of its relatively simple production and manufacturing, grenade launchers have been copied in large quantities and equipped with troops, whether they are the arsenals of the National Government, the Eighth Route Army, or the New Fourth Army.

It is naturally the case that there is no too much choice, but Yang Tianfeng wants to go beyond it, put aside the grenade launcher and directly equip a separate grenade launcher. Whether it is carrying, using, as well as range, firing rate, power, the 40mm grenade launcher should be able to beat the Japanese grenade launcher.

The principle is explained very clearly, which is similar to the combination of grenades (super caliber, rifles fired with empty packages) and grenade launchers (high and low pressure principle). The two technicians Sun and Zheng naturally understood that it would be very sure to make them when the drawings are in place.

According to the current technical capabilities of the arsenal, it is not difficult to solve the problem from scratch. However, it is not so easy to achieve a major breakthrough in quality and quantity and achieve the goal of a large number of equipment troops.

As for heavy mortars, Yang Tianfeng proposed two specifications: 100 mm and 120 mm. This is already the limit for people to carry shoulders, and it is no longer realistic to add caliber.

According to Yang Tianfeng's brain, if the 100mm or 120mm heavy mortar can meet the design requirements and use long-range charge shells, it can compete with the Japanese main artillery, the Type 41 75mm mountain cannon (range 6,000 meters), in terms of range, and exceeds most Japanese wing-level artillery. As interavailable firepower, it may play a surprising role in winning.

In fact, for Yang Tianfeng, it is certainly difficult to create new weapons, but it is even more troublesome to cultivate and train technical troops to use new weapons.

Taking the artillery of China and Japan at that time as an example, the gap in technical and tactical levels is not much worse than that in equipment. Although the Japanese artillery is at the bottom among the great powers, it already has the ability to operate indirectly on the map. It can observe the target through the observation post in front, find the coordinate points of the target on the map, and report the target position to the artillery unit through radio. The artillery unit does not need to directly observe the target to directly shoot by calculating operations on the map.

Until 1950, the Chinese artillery actually mainly aimed at shooting directly in the field of vision. During the War of Resistance Against Japan, only a few elite troops mastered the indirect aiming and shooting ability of the Japanese army. Most Chinese officers could not understand maps, let alone the illiteracy of soldiers. Therefore, it was difficult to organize artillery observation posts with ranging, terrain mapping and map interpretation capabilities.

The artillery troops do not master indirect aiming capabilities, which is very fatal in combat. This means that Chinese artillery can only strike pre-calibrated areas and is difficult to deal with Japanese troops appearing in other directions. It is also difficult to organize effective Xu Jin barrage to cooperate with infantry attacks during the attack.

Therefore, Yang Tianfeng's desire for intellectual youth is extraordinary. Not only does he gather all the soldiers who graduated from elementary school or close to elementary school in the army to train them, but he also recruited them through various channels. As for cultural learning in the army, it is difficult to create qualified intellectual youth without a year or two.
