Anti-Japanese War: Developing on my own, I brought back a US-equipped division

This sniper rifle is simply amazing.

Ah Fu was stunned and said, "Captain... this sniper rifle is really powerful, right? The Barrett sniper rifle... this is the most powerful sniper rifle I have ever seen!"

Shunliu smiled innocently and said, "This... With this gun, we can snipe the enemy from a distance outside the enemy's shooting range, killing the enemy without them even being seen!"

Su Zheng nodded and said, "That's right!"

"The Type 98K and Type sniper rifles you have now have an effective range of about to meters, so the impact of external factors is relatively small."

"But as the range increases, many factors will affect the trajectory. Ah Fu should be very clear about this!"

Ah Fu nodded and said, "That's right. The trajectory of a bullet is its ballistic trajectory. The ballistic trajectory is affected by many factors, including air resistance, climate, and the weight of the bullet itself."

In the entire Ghost Team, Ah Fu is the only sniper who has undergone systematic training.

Therefore, Ah Fu knows more.

Su Zheng: "That's right. For example, the caliber of the Barrett sniper rifle is 12.7mm. If a bullet of this caliber is to accurately hit a target 2 kilometers away, in addition to considering the influence of external factors, the sniper must also adjust the distance between the sniper rifle and the sniper scope."

The distance between the sniper rifle and the sniper scope is an important factor that affects the trajectory and whether a shot can be shot accurately.

Ah Fu, Shun Liu, Shui Sheng and the others were all listening very attentively.

Although Ah Fu had undergone systematic sniper training, because snipers of this era had only appeared recently, the level of attention paid to sniping and snipers was not very high, so the relevant theories and training about sniping were not very complete.

Therefore, Ah Fu did not know that the distance between the sniper rifle and the sniper scope had an impact.

Su Zheng raised the Barrett sniper rifle in his hand and said, "The Barrett sniper rifle uses the M3 optical super scope. The internal structure is not as simple as it looks. The internal design and results are very complicated."

"And this scope and sniper rifle are not fixed. Both can be adjusted in multiple directions and angles through knobs. The professional term is called calibration."

"A qualified sniper should be able to correct the trajectory based on external factors such as wind direction, wind speed, humidity, etc., and then accurately analyze and judge the distance to the target. Finally, he should accurately calibrate the scope and angle, so that he can kill the target at a long distance."

"Remember, being a sniper is not as simple as just being accurate!"

"Yes!"

Everyone present responded loudly.

Because all the members of the Ghost Team used Type 98 sniper rifles and Type k sniper rifles before, which have a relatively short range, so Ah Fu, a professional sniper, can do the training.

But now the Ghost Team is equipped with two Barrett sniper rifles, which requires more professional sniper training.

In order to enable these snipers to adapt to the Barrett sniper rifle more quickly and become more professional snipers, Su Zheng conducted sniper training for Afu, Shunliu and others.

The two biggest factors affecting sniper accuracy are trajectory and wind impact.

In terms of ballistics...because bullets, whether big or small, have a certain weight.

During the flight of the bullet, it will definitely be affected by gravity, and the trajectory of the entire ballistic trajectory is a parabola rather than a straight line.

The trajectory of a bullet is related to its speed, weight, etc.

If a bullet is traveling fast and the bullet is relatively heavy, then it will maintain its kinetic energy and inertia, and will ultimately be able to travel farther in a relatively straight line.

On the contrary, if the bullet head is very heavy and the initial velocity of the bullet is very low, then the trajectory is a parabola.

The second factor that affects ballistic flight is wind deviation.

The outdoor environment is more or less windy.

The bullet is flying in the air, so the wind will definitely affect the bullet's trajectory, deviation path, etc.

If the mass of the bullet is large, the impact of wind force on it will naturally be small, and vice versa.

Su Zheng personally taught the members of the Ghost Group, which benefited Shunliu, Afu, Shuisheng, Yang Dali and others a lot.

Xu Yihang, Xu Erhang, Xu Jinchuan and others are also members of the Ghost Group. They use cold weapons such as bows and arrows, but they still listen to Su Zheng's lessons very seriously.

At the same time, during these two or three days, the entire independent battalion was quickly resting and reorganizing the troops, while continuing to recruit soldiers and expand the troops.

After all, there are only more than a thousand people in the independent camp now.

And soon the three-month deadline was up.

There are only two days left, so Su Zheng is very worried. He doesn't know how the boss will deal with Li Yunlong.

According to Su Zheng's understanding of the boss, Li Yunlong would definitely not be shot, but he would definitely punish Li Yunlong.

You said Li Yunlong did not complete the military order mission?

During the peak period of the New 1st Regiment, the number of combat troops indeed exceeded 5,000.

You said Li Yunlong completed the military order mission, right?

When the three-month deadline was up, there were only about 3,000 soldiers left.

So this is a very tricky issue.

Su Zheng was also a little worried.

this day.

Su Zheng is still conducting the last day of sniper training for the Ghost Team.

As long as they go through this day of training, if the members of the Ghost Team can fully master and digest Su Zheng's sniper knowledge, they can become qualified snipers.

On the training ground.

Su Zheng looked at the members of the Ghost Team and said, "In the past two days, I have talked about a lot of knowledge related to professional snipers, such as the selection of sniping points, factors that affect sniping accuracy, etc."

"Factors such as the Coriolis force, temperature, humidity, air density, etc. can affect the trajectory of the bullet and ultimately determine whether it can be accurately shot."

"Today we are going to talk about another factor that affects sniping, and that is the Magnus effect!"

"You know, our bullets are very fast. If a gust of wind comes towards it from the cross section of the speed while the bullet is rotating at high speed, then the bullet will deviate laterally from the perpendicular line between the rotation direction and the wind direction. This is the so-called Magnus effect."

"Of course... Generally speaking, the effect of wind on bullets is not that great, and can even be ignored in some cases."

"But the bullet will fly in a certain parabola, which will cause the direction of the bullet to form a small angle with the angle of the bullet's movement when it reaches the end of the flight. This will generate a partial angular momentum perpendicular to the direction of movement, and the Magnus effect will occur."

"If the Magnus effect occurs, then we need to adjust the barrel. If the barrel is a right-hand spiral, then we should deviate to the right. If it is a left-hand spiral, then we should deviate to the left."

Sue was explaining the Magnus effect on a small blackboard.

Because the Magnus effect is quite profound, everyone was confused after listening to it.

However, after Su Zheng's explanation, I had a certain understanding of the Magnus effect.

Su was giving a lecture when he suddenly stopped.

Listening attentively with ears pricked up.

Such a scene made Shunliu, Afu and Wei Dayong stunned.

Su Zheng heard a sound...the roar of an engine from the sky.

Although the sound was very weak.

But Su Zheng's facial features were enhanced and his hearing was excellent...he could hear even the faintest roar of the engine.

After being stunned for a moment, Su Zheng was sure that the sound of the knife engine came from the air, so he shouted quickly: "Quick... the Japanese air raid is coming!"

Air raid?

Everyone's first reaction was to look up at the sky.

However, no Japanese fighter plane was found within the naked eye or visual range.

Su Zheng shouted again, "Don't look at it... move quickly... quick! The Japanese air raid is coming!"

Seeing Su Zheng like this, everyone did not dare to be careless and immediately began to evacuate everywhere and at the same time notified the villagers.

The originally quiet Xinzhong Village immediately became restless.

Ten seconds later, the Japanese fighter planes appeared over the Xinzhongcun base...

With Su Zheng's warning of more than ten seconds in advance, all personnel in the Xinzhongcun base were mobilized.

The soldiers of the independent battalion quickly evacuated the civilians into the air-raid shelter.

The construction of the Xinzhongcun base during this period certainly included the construction and development of air-raid shelters.

After three months of excavation and construction, a number of air-raid shelters were dug in the back mountain of Xinzhong Village.

These air-raid shelters can basically accommodate most of the people in the Xinzhongcun base.

"Hurry up...Run into the air-raid shelter!"

"Assemble in the air-raid shelter!"

"The soldiers of the independent battalion, cover the civilians' retreat, quickly!"

"Move quickly! Quick!"

............

When many ordinary people learned that the Japanese fighter planes were about to bomb, they began to run to the air-raid shelters.

The entire Xinzhongcun base was in turmoil.

Ten seconds later, the Japanese fighter planes appeared in the sky above the Xinzhongcun base.

After some deployment and coordination, Yoshio Shinozuka dispatched a total of 10 fighter planes from the First Army and the North China Front to bomb the Shinnakamura base.

10 fighter jets is not a large number, but it is not a small number either.

After all, it was just the bombing of a village.

With the bomb load of 10 fighter planes, it is basically possible to devastate an entire village.

Among the 10 fighter planes mobilized by the Japanese this time, two Zero fighters were used for escort and eight Type dive bombers were the main bombing force.

The Type 1938 dive bomber was a bomber used in large quantities by the Japanese in Zg. It was developed by Mitsubishi Heavy Industries in February 2.

This bomber not only has bombing capabilities, but also has reconnaissance missions. Therefore, this requires the Type 99 bomber to have the characteristics of a bomber, that is, high speed and high structural strength to withstand dive pressure.

At the same time, if it is to be used as a reconnaissance aircraft, it must be flexible enough.

Therefore, Mitsubishi Heavy Industries began to develop the Type 99 dive bomber based on the Type 97 dive bomber.

The maximum flight speed of the Type 424 bomber is 2920 km/h, and the total weight is as high as 1060 kg; the range is capable of continuous flight of 200 km, and the bomb load is not high, only 7.7 kg. In addition, there are three mm MG machine guns on board.

To be honest, the bombing intensity of the Type 99 bomber was not too great.

After all, the ammunition load is small.

Moreover, the Type 99 bomber is only considered a light bomber.

The famous Zero fighter was responsible for the escort.

The Zero fighter was also developed by Mitsubishi Heavy Industries in 1937. On April 1939, 4, the troops began to be officially equipped with the Zero fighter, which became the main fighter of the Japanese and also the fighter with the largest production volume of the Japanese.

It is worth mentioning that the Zero fighter is a propeller fighter with a single-seat, single-engine, straight-wing layout, and has the characteristics of small turning radius, fast speed and long range.

The empty weight of the entire Zero fighter is 1680 kg, and the maximum take-off weight is 2674 kg. The power unit is a Rising 1 engine with a power of 13 horsepower and a Rong 780 engine with a power of 1 horsepower, so the maximum flight speed can reach 12 kilometers per hour, the flight altitude is 950 meters, and the maximum range is 533.4 km. If auxiliary fuel tanks are hung, the range can reach 4200 kilometers.

As for the Zero fighter, its main weapon is the Type 20 mm machine gun.

Because of the power of the Zero fighter, it was called the Zero myth when the War of Resistance Against Japan broke out and even in the early days of the Pacific War.

However, the Zero fighter is not without certainty. When the Zero fighter is at high speed, its maneuverability will deteriorate sharply, its ailerons will be stiff, and its movements will be difficult.

At the same time, the wing structure of the Zero fighter also had serious defects. If the speed deteriorated too quickly during a dive, the aircraft would disintegrate in minutes.

In order to reduce the weight of the Zero fighter, self-sealing fuel tanks and automatic fire extinguishing devices were not installed. At the same time, the pilot's position was not protected by an armor layer. Therefore, once the aircraft was hit, it would easily cause the aircraft to catch fire and crash.

Simply put, the Zero fighter was relatively light, so many problems arose, such as its armor plates were not thick enough, the aircraft was not strong enough and was easily dismembered, etc.

But this did not prevent the Zero fighter from being rampant on the battlefield.

Because the anti-Japanese forces did not have air defense weapons, let alone air superiority.

The ten Japanese fighter planes dispatched this time were all from the Army Aviation Brigade.

In the eyes of these Japanese pilots, this time they were just bombing a base of the Eighth Route Army, so it was naturally a very easy, simple and enjoyable task.

Because the Eighth Route Army's equipment was very backward, it was impossible for them to have any anti-aircraft weapons.

It was a completely one-sided bombing.

After the bombing, they retreated back to celebrate and drink.
