A magazine of 30,000 rounds, you call it Hanyang

The Japanese 109th Division and th Division each sent a brigade.

The total number of people in the two brigades was more than 10,000, which made Zheng Kaixuan very troubled.

You know, a division only has two brigades under its command, but the division also has a division headquarters, engineers, signalmen, and many other arms. The total number of people in a division is more than 100,000, which is far more than the number of people in two separate brigades.

However, it is very likely that the two brigades will be cooperated with by the Japanese tank armored units and fighter air force units.

In this way, the combat effectiveness of these two Japanese brigades will not be worse than any ordinary division.

Although the spearhead regiment is powerful, it still has some difficulties facing more than 10,000 Japanese soldiers who have air superiority and heavy weapons such as ground tanks and armor.

Not to mention whether Wei Zhuang can hold on, even if it can barely hold on, the people under Zheng Kaixuan, the spearhead group he personally formed, will probably suffer heavy casualties.

Zheng Kaixuan now placed his hope on the Japanese epaulette in his hand.

This shoulder strap was obtained after killing the Japanese 134th Regiment Captain Sakamoto Ken.

The epaulettes of Colonel are also the highest-ranking Japanese epaulettes that Zheng Kaixuan has obtained so far.

"System, use this colonel's epaulettes and modify them..."

Zheng Kaixuan hesitated in his heart.

Currently, he has four types of level 13 weapons and equipment: Hanyang-made fully automatic rifle tank, Triumph mortar tank, Triumph grenade tank and Triumph bulletproof vest.

Apart from the bulletproof vest, the other three weapons currently do not have the power to deal with the Japanese planes and tanks.

Zheng Kaixuan was a little confused about which one to modify first.

"It's so difficult to choose. Forget it. How about you help me choose one to modify. It would be best if it can deal with Japanese tanks or planes after modification." Zheng Kaixuan said half-jokingly in his heart.

[Ding! Congratulations to the host, the host has successfully modified the tier 14 Hanyang fully automatic rifle using a Japanese colonel's shoulder patch.]

"Is this possible? Is it possible?"

Zheng Kaixuan didn't expect that the system would actually help him make a choice just because he said it casually.

[Ding, a tier 12.7 Hanyang-made tank has a new mm twin-linked machine gun at the rear, which can be used for anti-aircraft fire.]

[Effective air-to-air range: 2000 meters. Firing rate: 2000 rounds per minute...]

"A machine gun that can be used for anti-aircraft fire?"

As a military enthusiast, Zheng Kaixuan quickly understood what was added to the 14-level Hanyang tank.

Anti-aircraft machine gun!

In the early days of World War II, the Japanese fighter planes flew slowly and often carried out low-altitude combat missions.

Anti-aircraft machine guns can be used to deal with the Japanese fighter planes of this period!

"Captain, the weapons support team has developed a new weapon. Please go check it out..."

Just then, a guard came to deliver a letter.

"Okay, I got it, I'll be right there."

Zheng Kaixuan knew very well that the so-called newly developed weapon mentioned by the guard was nothing more than the anti-aircraft machine gun that he had just modified using the system.

"Brother Xizi, let's go and take a look."

Wang Xikui agreed and followed Zheng Kaixuan out.

The two men came into the compound and saw from afar a group of people from the weapons support team surrounding the Hanyang-made tank.

This anti-aircraft machine gun is mounted at the rear of the tank and looks very conspicuous.

It is said to be one machine gun, but in fact it is a twin machine gun.

The same base, two barrels, and firepower twice that of an ordinary anti-aircraft machine gun!

The level 14 tank has also undergone significant changes compared to the previous one. A new operating position has been added under the anti-aircraft machine gun.

In other words, this level 14 Hanyang tank is equipped with a fully automatic rifle at the front and a twin anti-aircraft machine gun at the rear.

There is a big difference between anti-aircraft machine guns and Hanyang fully automatic rifles.

The effective range of the 800th-level Hanyang fully automatic rifle is only meters.

However, the effective range of the anti-aircraft machine gun for high-altitude air defense is as high as 2000 meters.

The Hanyang fully automatic rifle is not incapable of airborne shooting, but it is not very effective against enemy aircraft.

First, the range is a bit short, and second, the damage of 6.5mm rifle bullets to Japanese fighter planes is limited. Even if they hit the Japanese fighter planes, it is difficult to shoot them down.

The fourteenth-level anti-aircraft machine gun is different.

This anti-aircraft machine gun is a large-caliber machine gun with a caliber of 12.7 mm and is extremely powerful.

The bullets it fires are mainly armor-piercing incendiary bombs and armor-piercing high-explosive bombs with armor-piercing capabilities.

You only need to hit the enemy plane with 1-2 bullets to destroy it!

In this era, it can be said that it is a powerful weapon for low-altitude strategic air defense and a nightmare for Japanese fighter planes.

This anti-aircraft machine gun, like the Hanyang machine gun, is equipped with a 3000-round flexible ammunition belt, which is stored in the carriage and under the seats.

There is no need to worry about the sustainability of firepower.

In addition, one of its biggest advantages is that, like the Hanyang-made fully automatic rifle, the gun body and barrel are forged using special steel produced by the system.

This material will not cause the barrel temperature to become too high due to long shooting time, so there is no need to worry about jamming or explosion.

The barrel and rifling will basically not be damaged and basically do not need to be replaced.

To put it simply, you can just build as many as you want without any worries. There will be no problem even if you use up 3,000 rounds of bullets in one go.

In addition, it is not integrated with the tank and can be removed from the tank and used separately when necessary.

Its aiming device is also very easy to use, and it comes with an infrared laser sight that adapts to the gun body.

During combat, the laser can be turned on and off at will.

In addition to being used to shoot aerial targets, it can also be used for flat shooting.

The power of flat shooting is also very great.

To give a simple example, when dealing with the Japanese transport trucks of the Sakamoto Regiment at Heiyunkou, the Triumph mortar often needed several rounds of continuous fire to penetrate the carriage and kill the Japanese inside.

This anti-aircraft machine gun can easily penetrate the Japanese trucks and even light armored vehicles without any effort.

Armor less than 20 mm is no different from paper in front of it.

If you use it to fight the Japanese, it is no exaggeration to say that it can directly smash the Japanese's body!

The Barrett sniper rifle of later generations was called the human cannon. It also used 12.7mm large-caliber ammunition, but its power was three points inferior to that of the Triumph anti-aircraft machine gun.

Looking at the new weapons in front of him, Zheng Kaixuan was very satisfied.

"If the Japs dare to come, we'll give them a damn surprise!"
