Actually, first of all, it was decided from the bullet. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

Now submachine guns, which use pistol bullets, why not just use rifle bullets?

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

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

Therefore, the current submachine gun can only use pistol bullets, and the recoil is small, which is convenient for continuous firing, but the pistol bullets are not powerful enough at medium and long distances, and the distance effectively controlled by the submachine gun is about 150 meters.

In this way, problems arise, and according to the experience of the First World War, rifles combat distances are shortened, mostly firing at distances of up to 400 meters. Traditional bolt-action rifles, the range of a thousand meters is too long, it is no problem for snipers, if everyone uses it like this, it is too wasteful.

So, this necessitates the study of a new ammunition!

Historically, until 1934, Germany began to research and develop short cartridge rifle cartridges to control the accuracy of shooting when firing continuously. This type of cartridge ammunition is known as an intermediate-power cartridge.

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

It can be found that the study of bullets is even longer! There are many aspects to consider and trade-offs! And now, it's just the time to start researching!

So, at this time, you can add a new point of view, small caliber!

Now, the development of intermediate-power guns and ammunition in various countries is based on the original caliber, or it is possible that it is for the purpose of unifying the caliber and facilitating the manufacture of the barrel?

And Ciric knows that in fact, reducing the caliber is more beneficial, and one of the important reasons is that after reducing the caliber, reducing the weight of the bullet can allow a single soldier to carry more bullets!

You can see it from the trend of later generations!

Therefore, in the next step, Ciric elaborated on the intermediate power bullet, encouraged Erma to research the new small-caliber series, and gave several solutions for Ermar to compare and choose from.

This matter can't be rushed! Anyway, there are still several years before the big war, and now, as long as the submachine gun is made, it will be the most powerful individual weapon of 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 MP18 submachine guns of the Germans in trench warfare, bolt-action rifles, can they compare to the rate of fire of submachine guns? So, they simply stipulated that the Germans were not allowed to develop new submachine guns!

The Germans, of course, did not listen to this Versailles treaty, which is why this new submachine gun was developed!

At least, for the first few years, it's fine! The choice of small-caliber medium-power rifle cartridges must be made carefully!

When he came out of Elma's company, it was already dark, and Ciric was riding in a car, driving on the road.

Ahead, Graff was intently driving.

As a national car, the Beetle is very suitable, to meet the needs of a family travel, and relatively cheap, but, as the head of the car, it is not enough, only two doors, sitting in the back of the chief, getting on and off the car is extremely troublesome, and the rear engine, the noise is even greater.

What Ciric was riding in was a BMW 325.

This is not the sedan of 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 program of light, medium and heavy specifications, among which the task of developing a half-ton light off-road vehicle falls to three German civilian car factories: Honamog, BMW and Stoewer.

After all, all kinds of civilian vehicles are not capable of undertaking military tasks, and their off-road capabilities cannot meet the standard.

In 1936, the first prototype produced by Stoewer, the R180, was launched under the name Einheits-PKW.

Since none of the German OEMs had the scale to undertake large-scale orders for military vehicles on their own, the Einheits-PKW was produced by other manufacturers, including the R180 and its upgraded version R200 produced by Stoewer; Hanomag's product is called 20B; BMW produced it became the BMW 325.

And now, history has undergone a small change, because BMW hired a large number of engineers to join the R&D team in the last sweep to the UK, so BMW took the lead in completing the development and passed the military acceptance.

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

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

How advanced are these technologies? You must know that the gearbox of the average car was only 3 speeds, even if it was a domestic Poussin in the 90s, it was still 4 speeds!

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

The brain is constantly at high speed, and Ciric thinks too much about the country.

The historical knowledge of later generations is quite rich, which is summed up by many people, and now, one by one, it is all up to Ciric to deploy it alone, as if it is an infinite number of concurrent threads, how powerful does a CPU need to deal with it?

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

Ahead, Graff was looking at the road very seriously, and two headlights illuminated the dark street.

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

Ciric in the back, opened his eyes suddenly, in Germany, he actually wanted to come to his own trouble? Hum! It's just looking for death!

"Boom!" At this moment, the car on the side had already hit it hard!
