Chapter 119 It's Getting Dark

In fact, the first decision is from the bullet.

Today's submachine guns use pistol bullets, so why not use rifle bullets directly?

This is because traditional rifle cartridges are too powerful when used in automatic rifles, and cannot effectively control the jumping of the gun and the impact of recoil during automatic shooting.

Think about using the current full-power rifle bullets, which can only be used for machine guns. The recoil is not something that ordinary infantry can withstand. At the same time, it is impossible to equip them all in the infantry squad. It is too heavy!

Therefore, current submachine guns can only use pistol bullets, which have low recoil and are convenient for continuous firing. However, pistol bullets are not powerful enough at medium and long distances. The effective control distance of submachine guns is about 150 meters.

In this way, problems arise, and according to the experience of the First World War, the combat distance of the rifle is shortened, and most of them are fired within a distance of 400 meters. A traditional bolt-action rifle, with a range of one thousand meters, is too far for snipers to use. If everyone uses it like this, it will be too wasteful.

So, this requires researching a new ammo!

Historically, until 1934, Germany began to research and develop short-barrel rifle bullets, in order to take into account the power and control the shooting accuracy during continuous shooting. This type of short-cartridge ammunition is called an intermediate-power round.

It was not until 1941 that Germany successfully developed and began to produce 7.92×33 mm rifle cartridges. The length of the cartridge case was reduced from 57 mm to 33 mm for the original 7.92×57 mm standard rifle cartridge, and the charge was reduced from about 3 grams to about 1.6 grams. .

It can be found that the research on bullets is even longer! There must be multiple considerations and trade-offs! And now, it's just the beginning of the research!

So, at times like this, you can add new perspectives, small caliber!

Now, the development of intermediate-power bullets in various countries is based on the original caliber, and it may also be for the purpose of unifying the caliber, which is conducive to the manufacture of the barrel?

And Cyric knows that, in fact, it is more beneficial to reduce the caliber. One of the important reasons is that after the caliber is reduced, the weight of the bullet can be reduced, so that individual soldiers can carry more bullets!

It can be seen from the trend of later generations!

Therefore, in the next step, Cyric made some elaborations on the intermediate power bullets, encouraged Irma to study a new small-caliber series, and gave several options for Irma to compare and choose.

Don't rush this matter! Anyway, there are still several years before the war, and now, as long as the submachine gun is produced, it is the most powerful individual weapon in this era!

How powerful is a submachine gun? Just look at the Treaty of Versailles. In World War I, Britain and France were quite afraid of the German MP18 submachine gun in trench warfare. Is the bolt-action rifle comparable to the rate of fire of the submachine gun? Therefore, they simply stipulated that the Germans must not develop new submachine guns!

Of course the Germans didn't listen to the Versailles Treaty, so they developed this new submachine gun!

At least, it was fine for the first few years! The choice of small-caliber medium-power rifle bullets must be careful!

It was already dark when he came out of the Irma Company, and Cyric was driving on the road in his car.

Ahead, Graff was driving intently.

As a national car, the Beetle is very suitable, it meets the needs of a family to travel, and it is relatively cheap, but if you use a car as a chief executive, it is not enough. With only two doors, the chief sitting in the back row is all about getting on and off. Extremely troublesome, and the rear engine, the noise is even greater.

Cyric was riding in a BMW 325, the latest from BMW.

This is not the sedan of the future, this is a pure off-road vehicle!

In addition to various military armored vehicles, the army has also launched light, medium and heavy military vehicle development plans. Among them, the task of developing a half-ton light off-road vehicle falls on three German civilian car factories, Honamog, BMW and Stoewer.

After all, various civilian vehicles cannot undertake military tasks, and their off-road capabilities cannot meet the standards.

In the history of later generations, this plan was developed intensively for several years by the best German designers at that time. In 1936, the first prototype R180 produced by Stoewer was officially launched and was named the Einheits-PKW series.

Since none of the German OEMs have enough scale to undertake large-scale military vehicle orders alone, this has also led to the production of Einheits-PKW by other manufacturers. Among them, the models produced by Stoewer are R180 and its upgraded version R200; Hanomag's The product was called the 20B; what BMW produced became the BMW325.

But now, a small change has taken place in history, because BMW hired a large number of engineers to join the R&D team in the last scan of goods in the UK. Therefore, BMW took the lead in completing the development and passed the military acceptance. .

As in history, this BMW 325 adopts an advanced H-shaped steel chassis, a front engine, a five-speed manual transmission, a full-time four-wheel drive system, three differential locks at the front, middle and rear, and independent four-wheel double wishbones. Suspension, and the most sci-fi four-wheel steering, etc.

In addition, in order to ensure that the oil can have sufficient oil pressure in any environment, the car also uses an OHV bottom camshaft and a dry oil pan design.

How advanced are these technologies? You must know that the gearbox of ordinary cars in those days was only 3-speed, even the domestic Poussin in the 1990s was still 4-speed!

The advanced equipment was given to the First Armored Division first, and Cyric unceremoniously asked for one as his own means of transportation.

The brain has been in high gear, and Cyric thinks too much about the country.

The historical knowledge of later generations is quite rich, which is summed up by many people, and now, each of them is carried out by Cyric alone, just like countless concurrent threads, how powerful a CPU can it handle?

Cyric was tired and leaned back in the back seat, Cyric closed his eyes.

Ahead, Graff looked at the road very seriously, two headlights illuminating the dark street.

Suddenly, two bright lights appeared on the side street! These two rays of light shone directly into the cab!

Cyric behind him suddenly opened his eyes. In Germany, he actually wanted to trouble himself? snort! It's just looking for death!

"Boom!" At this moment, the car on the side had slammed into it!
