Qin Chuan actually knew what Conrad said.

Germany actually noticed the problem that Qin Chuan said very early, that is, the problem of the gap in firepower between rifles and submachine guns.

To a certain extent, the long range of the rifle is not necessary on the battlefield, on the one hand, the distance between the warring parties is generally not that far, and if it is really that far, it is difficult to hit, so the long range is not very significant.

On the other hand, there are completely alternative weapons at long range, such as machine guns and mortars.

So what the infantry really needed was a high-velocity weapon with a range of about 400 meters.

At one time, it was also considered to use the principle of a submachine gun to be directly converted into a rifle...... This is actually a machine gun, and its recoil is beyond the reach of an ordinary soldier.

So Germany was very forward-looking in the development of an intermediate power bomb.

This study began in 1934, and after repeated experiments, it was not until 1941 that the 7.92×33mm rifle short cartridge was determined.

Its length was shorter than the German standard 7.92×57 mm rifle cartridge at the time, the bullet was lighter, the gunpowder fired was reduced, the charge was reduced from 47 grains (note: the grain is a unit of weight used in the United Kingdom, the weight of a grain of barley is 1 gram, 47 grains is about 3 grams) to 24.6 grains (about 1.6 grams), and the weight of the bullet head was reduced from 198 grains (about 12.8 grams) to 123 grains (about 8 grams).

As a result, the effective firing range was accordingly reduced to four hundred meters. The length of the bullet is one-third shorter than that of the original Mauser rifle cartridge. The recoil of the gun is greatly reduced, and the technical bottleneck of automatic continuous firing can not be fired continuously and accurately is well solved.

Once you have the bullets, the next step is to develop the corresponding rifle...... In fact, in the research and development of firearms, the development and determination of bullets is more important, there is a saying called "look at the gun first to see the bullet", the bullet basically determines the range, lethality and other basic performance, the gun is actually a tool to launch the bullet.

But it was suppressed when reporting to Hitler.

"The Führer thought that it had a limited range and could not be compared with a machine gun!" "So at long distances it will be suppressed by enemy machine guns and rifles, and at close ranges it will be inferior to submachine guns!" ”

Hearing this, Qin Chuan couldn't help laughing.

An assault rifle is a kind of equipment between a rifle and a submachine gun, you can certainly say that it is not as long as a rifle and lighter than a submachine gun, but it can also be said that the rate of fire is higher than that of a rifle and the power is greater than that of a submachine gun, depending on what angle you look at.

"On the other hand!" Conrad continued: "This rifle had to use new ammunition, and it could not use the large stockpiles of Mauser rifle bullets that existed. Moreover, it can also fire in bursts, and the consumption of bullets in real combat must be very impressive. This requires us to re-prepare a whole new set of ammunition systems, which will undoubtedly add a lot of additional burdens to the production of the country, as well as to the logistics of the troops! ”

"But you know!" Qin Chuan said: "These efforts are worth it, it will bring us victory after victory!" ”

"Yes, I believe that!" Conrad nodded in agreement, but then shrugged helplessly: "But the Führer disagrees!" ”

"It doesn't matter!" Qin Chuan said.

"No, it's important!" Conrad looked at Qin Chuan with a puzzled face: "I don't know why you think this is not important, the problem is that without the consent of the Führer, no one can produce it privately and equip it with troops!" ”

"Colonel!" Qin Chuan raised his head at the sketch in Conrad's hand and asked, "Do you think it's more like a rifle or a submachine gun?" ”

"Compared to rifles...... It's, of course, more like a submachine gun! Conrad replied.

"So, do you think the Führer would have denied a submachine gun?" Qin Chuan asked again.

"You mean ......"

Qin Chuan nodded and said, "We just need to give it a name for the submachine gun!" ”

"Yes!" Conrad couldn't help nodding excitedly: "It's just a submachine gun, the only difference from the submachine gun is that the bullets are different, but...... And how could the Führer pay attention to whether the bullets would be the same? ”

Thinking about it, Conrad couldn't help but hug Qin Chuan and said, "Great, Captain, you have saved another research that we have been studying for many years, and even made it even better!" ”

What Conrad didn't know was that this couldn't actually be regarded as Qin Chuan's credit...... Historically, German researchers did just that, and in order to prevent Hitler from arrogantly denying this invention that could obviously play a great role on the battlefield, they finally submitted to Hitler for approval under the name MP43\MP44, but Hitler really did not notice the abnormality and approved the production.

It's just that by then it was already too late for production.

"So, Colonel!" Qin Chuan then asked Conrad: "Now you can tell me what those scientific researchers you brought are doing, you won't tell me that you brought them to produce equipment, right?" ”

"No, of course not!" Conrad replied, "Captain, since we have been friends for many years, and I consider you to be a friend of mine for many years, I don't want you to get into Holm with all this, of course, and myself, so I intend to help you!" ”

"Help me?" Qin Chuan was a little puzzled.

"Guess what they do!" Conrad said, "I'm sure you'll guess!" ”

Qin Chuan thought for a moment, and then asked Conrad hesitantly: "Are you talking about V1?" ”

"Clever!" Conrad replied.

"You've already produced a radio-guided V1?" Qin Chuan couldn't help but be surprised and delighted.

"Yes!" Conrad nodded: "We have done experiments, if we make another guidance adjustment in the target area, then we can reduce the error to within a thousand meters, I brought three sets of equipment on three gliders, but unfortunately now there are only two sets left!" ”

After a pause, Conrad asked again: "With a margin of error of one thousand meters, it shouldn't be a problem to bomb the West Bank!" ”

"Of course!" Qin Chuan replied.

A one-kilometer error is not ideal, but it is staggering enough for this era.

"Now it's time to improve its accuracy even more!" Qin Chuan said.

"Further?" Conrad asked, "How?" ”

"Have you ever thought about TV guidance?" Qin Chuan asked.

Conrad couldn't help but open his mouth wide and couldn't close it for a long time: "You mean...... We put a camera on it and control it to hit the target? ”

"Of course!" Qin Chuan replied.

"Great, Captain, you're a genius!" Conrad jumped up excitedly: "Why didn't we think of it? Oh no...... I've got to tell Braun about this right now, or what if I die? And, of course, that 'submachine gun'! ”
