In fact, it is determined first of all from the bullet.

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

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

Think about using the current full-power rifle bullets, you can only use them for machine guns. The recoil is not something that ordinary infantry can withstand. At the same time, it is impossible to fully equip 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 at medium and long distances, and the effective distance of the submachine gun is about 150 meters.

In this way, problems arise. According to the experience of World War I, the combat distance of the rifle was shortened and most of them fired within 400 meters. Traditional bolt-action rifles have a range of one thousand meters, so it is no problem to use for snipers. If everyone uses it like this, it would be a waste.

So, this requires researching a new ammunition!

Historically, until 1934, Germany began to research and develop short cartridge rifle bullets to take into account both power and continuous shooting. This type of short cartridge ammunition is called intermediate power bullets.

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

It can be found that the research on bullets is even longer! There are many aspects to consider and make choices! And now, it is just the time to start research!

So, at this time, you can add new ideas and small-diameter!

Now, countries are developing intermediate power bullets in the original caliber, which may be for the purpose of unifying the caliber and conducive to the manufacturing of the barrel?

And Cialek knew that in fact, reducing the caliber is more beneficial. One of the important reasons is that after reducing the caliber, reducing the weight of the bullet can allow individual soldiers to carry more bullets!

It can be seen from the trends in later generations!

So, next, Cialis gave a brief explanation of the power bullets in the middle, encouraged Irma to study the new small-caliber series, and gave several solutions to allow Irma to choose from it.

You can't be anxious about this matter! Anyway, there are still several years before the war, and now, as long as you create a submachine gun, it will be the most powerful individual weapon of this era!

How powerful are submachine guns? Just look at the Treaty of Versailles. In World War I, Britain and France were quite afraid of the Germans' MP18 submachine guns. Can the bolt-moving rifles compare to the rate of fire of submachine guns? Therefore, they simply stipulated that the Germans were not allowed to develop new submachine guns!

Of course, the Germans did not listen to the Treaty of Versailles, so they developed this new submachine gun!

At least, there was no problem in the past few years! The choice of medium-power rifle bullets with small caliber must be cautious!

When I came out of Irma, it was already dark and Cyric was riding in a car and driving on the road.

In front, Graff was driving with concentration.

As a national car, the Beetle is very suitable to meet the needs of the family's travel and is relatively cheap. However, as the leader uses a car, it is not enough. With just two doors, the leader sitting in the back row is extremely troublesome to get on and off the car, and the rear engine makes the noise even louder.

The one that Cirick was riding was a BMW 325, the latest BMW company.

This is not the sedan from later generations, this is a pure off-road vehicle!

In addition to various military armored vehicles, the army has also launched a military vehicle development plan of three types: light, medium and heavy. The task of developing a half-ton light off-road vehicle fell on three German civilian vehicle manufacturers, Honamog, BMW and Stoewer.

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

In the history of later generations, this plan was developed by several years by the most outstanding 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 vehicle companies 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 which Stoewer's model is R180 and its upgraded version R200; Hanomag's product is called 20B; BMW's BMW 325.

Now, history has changed slightly. Because BMW hired a large number of engineers and joined the R&D team during the last time he went to the UK to buy goods, BMW took the lead in completing the development and passed the military acceptance.

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

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

How advanced are these technologies? You should know that the gearbox of ordinary cars at that time was only 3 speeds, even if it was a domestic Poussan in the 1990s or a 4 speed!

The advanced equipment was first given to the First Armored Division, and Cialis made a request for one without hesitation as his own transportation tool.

The brain has been running at high speed, and Cirick has thought too much about this country.

The historical knowledge of later generations is quite rich, which was summarized by many people. Now, it depends on Cialek to deploy it alone, just like countless concurrent threads. What a powerful CPU that can handle it?

Cialick was tired and leaned against the back seat, Cialick closed his eyes.

In front, Graff looked at the road very seriously, and two headlights illuminated the dark streets.

Suddenly, two lights appeared on the street on the side! These two lights shone directly into the cab!

Cialek behind him suddenly opened his eyes. In Germany, he actually wanted to come and cause trouble for himself? Humph! It's simply asking for death!
Chapter completed!
