As for the selection of the Type 81 squad light machine gun, it is mainly based on logistical considerations, it can be used with the main parts and ammunition of the Type 81 assault rifle, and the maintenance and logistics supply are very convenient, and although the performance of the Type 81 squad light machine gun in history is not particularly outstanding in Shijie, it definitely exceeds any kind of World War II light machine gun. Moreover, the requirements for materials and processing technology of the Bayi gun clan are relatively low, which is almost the limit of what can be mass-produced in the Soviet area at present, and those small-caliber firearms in the back, Hu Weidong will never be able to do it no matter how capable he is

Considering that the 81 Gun Clan was already advanced enough in this era and would inevitably equip the squadron for a long time, Hu Weidong also made some improvements to it, such as installing tactical guides on it (however, due to the industrial base of the Soviet District, this seemingly simple design caused the mass production of the 81 Gun Clan to be delayed for half a year. Later, it was handed over to Liu Ding, Mao Yike and other firearms experts and Wu Yunduo, who is now "Shibei Three Days", to make it more in line with the needs of the Anti-Japanese War than the historical prototype (for example, the butt of the Type 81 rifle uses the wooden stock used in the Type 81 prototype gun, rather than the folding butt used in the improved Type 81-1, this is because hand-to-hand combat in the Anti-Japanese War was much more frequent than in later generations, and the second is because wood is cheap and easy to obtain and steel is expensive and lacking, not to mention composite materials, Therefore, it is more economical to use wooden pallets. ), but also because of this, it was not finalized until August 37, and the equipment of the troops began at the beginning of 38

The biggest gain of the Red 15th Army's advance into North China was the hundreds of artillery pieces of various types, but the towed artillery still had a great impact on the mobility of the whole army. In particular, the 6 240mm heavy howitzers that cannot be towed as a whole, and must be disassembled into two to be able to pull even if a special tractor is used, have become chicken ribs, after all, after the outbreak of the Anti-Japanese War, the devil's aircraft will be far more rampant than in North China. This kind of heavy artillery shelling has to be prepared for a long time, which is really too dangerous

Therefore, Hu Weidong naturally thought of self-propelled artillery, but there is no suitable chassis at the moment, the devil's tank armored vehicles are generally too small and too light, not to mention, there are only so many iron guys of the Red Third Front Army are not willing to convert it into self-propelled artillery to use, so Hu Weidong thought about it, Zuihou's decision is to engage in vehicle-mounted artillery, so that as long as there is a road, it can maneuver at high speed. In the relatively flat terrain of North China and the Central Plains, as long as the marching distance is not too far, cross-country is not impossible.

At present, China cannot even produce automobiles independently, and it is naturally not easy to develop on-board artillery. However, in Hu Weidong's eyes, the structure of the vehicle-mounted artillery is not complicated, and since the tractor can pull the cannon, it must also be able to carry it, as long as it is a sufficiently strong and stable towed chassis. This work has certain difficulties for the Gongxian Arsenal, which currently does not even have a large-scale rolling mill. Fortunately, the quantity needed is not much, and the part that cannot be produced by machine is simply made up by some skilled workers, and even folk blacksmiths, relying on extraordinary skills

Although it took great effort to create a chassis that could be loaded with heavy guns, two new problems that could not be avoided appeared, one was the high center of gravity. If the cannon on the vehicle is shelled horizontally, it will easily cause the body to overturn, but if it is longitudinal, it will be okay. However, if the barrel cannot be turned freely, it has to be adjusted by the turning of the body. Flexibility is too bad; The second is poor stability, which further weakens the vehicle-mounted artillery is not as good as the speed and off-road ability, Hu Weidong carefully observed, that the reason why the stability of the sample car is poor, on the one hand, because the center of gravity is high, on the other hand, because the tires do not meet the requirements

"Can't we even make such a simple thing by ourselves?" Hu Weidong, who was in an unhappy mood, kicked the tires of the sample car twice as if he was angry, and suddenly his heart moved, "By the way, I remember that you can fill the tires with water instead of inflating (in fact, most military tires are solid, but Japan during World War II did not produce solid tires, and can only use ordinary pneumatic tires, so it is easy to have accidents during the march.) ), can significantly increase the counterweight, and the center of gravity of the body is lowered, which increases the stability of the vehicle-mounted gun and the smoothness of the ride "...,

Shiyan's effect was very obvious, this problem that was originally helpless was solved so easily, this matter further increased Hu Weidong's prestige in the Jishu team, and everyone was deeply educated, and understood that "even simple knowledge, as long as it is used properly, can solve many seemingly difficult problems".

In addition, Hu Weidong also selected some young and middle-aged technicians with excellent skills and flexible minds, starting with parts and components, and tried to imitate the captured devil engines (1 or 2 of each model were removed, including airplanes and tanks, for which Hu Weidong was complained by the commanders and fighters of the air force and armored brigade for a long time, because there were more cars, so the drivers were more acceptable). Although there is a certain gap between the performance and the prototype, and there are many places that rely on manual skills to complete, the production efficiency is greatly reduced, but if it is not for this foundation, the later introduction of jishu equipment, digestion and absorption can not be so fast.

Hu Weidong's reputation is now far more famous than when he first advanced into North China, so the number of reporters who ventured to the Soviet zone to interview him is also increasing, and some of them are foreigners. Smedley

Although historical celebrities will always make travelers pay special attention, Hu Weidong has never been superstitious about historical celebrities, even if he was very fond of Snow, Hu Weidong tried first before finally putting his heart into him. Although Smedley has been very helpful to the Red Party in history, her self-righteous personality and impatient temper have also made her do bad things with good intentions more than once, leaving aside the well-known Mao He breakup, she made Lao Chiang's promises public without permission after the "Xi'an Incident", and as a result, Lao Chiang thought that the Red Party did not keep its promises, and the already fragile trust between the two parties was therefore deeply rifted again before the "77 Incident", and although the leaders of the Red Party at that time were very dissatisfied with this, because " There are only a few international friends, they must be cherished, and Smedley is not out of any malice, Zuihou They had to swallow this bitter fruit by themselves (to be continued......
