The 6.8mm bullet was born to deal with heavy body armor. Facts have proved that the problems faced by the US military are universally faced by the world, so the solution the US military has come up with can indeed meet the needs of most battles.

The 5.56x43mm bullet has proven to be seriously insufficient in penetrating body armor, and the 7.62x39mm M43 intermediate bullet has seriously insufficient armor-piercing ability. As the most commonly used medium-caliber 7.62nato bullet in NATO, although it is 7.62x51mm, the caliber ratio

6.8 is larger, but its armor-piercing ability is still not as good as the latest 6.8x51 bullet.

Why this happens is because the 6.8 bullet has a higher chamber pressure, a faster exit speed, and a higher bullet cross-sectional kinetic energy ratio.

The muzzle kinetic energy of the 5.56nato bullet is 1700 joules, the muzzle kinetic energy of the 7.62nato bullet is 3400 joules, the muzzle kinetic energy of the 7.62mm M43 intermediate bullet, which is the bullet used by AK47, is almost 2000 joules, and the 7.62mm R bullet, too

The muzzle kinetic energy of the machine gun bullets used by Patrick fluctuated around 3,500 joules.

The muzzle kinetic energy of the new 6.8mm bullet is 3700 Joules, which is greater than the kinetic energy of the most commonly used 7.62mm calibers. In other words, the cross-section of the bullet is still small, so the penetration ability is naturally stronger.

Therefore, the new bullet is claimed to penetrate level 4 body armor within 400 meters, while the 5.56mm bullet cannot penetrate level 4 body armor against a body armor jacket, and the 7.62nato bullet cannot penetrate level 4 body armor at any distance. This is the difference.

To put it bluntly, it is a new gun and new ammunition for high-light applications. Its armor-piercing capability is better than the M60 machine gun, the PKM machine gun, the M14 rifle, the M4 rifle, the AK47 rifle, the M21 sniper rifle, the M24 sniper rifle, and the SVD sniper rifle.

It has stronger armor-piercing ability than these guns.

But having said that, there are advantages and disadvantages. The penetration ability of the new bullet is directly improved by a level. However, the high kinetic energy of the muzzle means that it cannot be fired continuously because it cannot be controlled. Then the high chamber pressure means that the service life of the barrel is short.

, and the high muzzle velocity also means that the firing noise is extremely loud, which cannot be suppressed by ordinary silencers.

Now Gaoguang and the others have a Sig 6.8. With this configuration, the only team in the world except the US military that is trying out the new gun is King's Defense.

If you can't fire continuously, it's better to use semi-automatic. It's better to get one shot every time than to hit but not be able to penetrate the body armor.

After I got the new gun, the highlight quickly showed the effect that the new gun should have.

He killed one with one shot, and then Gao Guang turned his gun and aimed at the second enemy who was retreating while shooting. No one was knocked down by the gunshot, but Gao Guang quickly fired two more shots, and finally the enemy was about to reach the wall.

Hit it when it opens.

The battle has come to an end.

According to Gao Guang's judgment, the battle should be over at this point, because the enemy's first attack has obviously failed, and they are unable to continue fighting. Even if they want to reorganize the attack, they have to retreat and gather their men before they can attack again for the second time.

To launch an attack.

Gao Guang picked up his HK416 from the ground, then handed the gun to Mike, and said urgently: "Go and take off my rifle and bullets, change guns, everyone change guns!"

The sound of gunfire quickly became sparse, and the explosions stopped completely. No grenades were used in this battle, because both sides were not within a distance of throwing grenades.

Gao Guang was still in shock, and he gasped: "I have to ask what's going on, why the enemy came in so easily, how this battle was fought..."

According to experience, this battle will come to an end, and both sides can take the opportunity to reorganize quickly. But just after Gao Guang finished speaking, he heard someone shouting from the top of the building: "The enemy is coming! Prepare to attack!"

Is it so fast? In less than a minute, the enemy can attack again?

The gunshots that had just been silent became intensive again, and the enemy started shooting at the friendly forces hiding on the roof and in the house on the periphery. This time, no one rushed directly into the factory area, but they started to suppress fire again.

This battle is a bit inexplicable.

If it is a high-light command, then he will never launch an attack without solving three commanding heights with strong firepower.

The enemy's fighting style is extremely tough, that is, they have to charge in despite the firepower of the defenders, but this is of no great use other than getting killed.

It seemed that the enemy regarded Gao Guang and the others as idiots and thought they could take down the factory with a single charge.

"The enemy has a problem!"

"This is a wrong way of playing. What does the enemy want to do?"

Patrick and John have rich experience, mainly in dealing with such large-scale battles. Now they both feel that the way this battle is fought is very problematic.

Paul said anxiously from the side: "I think the enemy did not cooperate well. There must be a problem with their coordination. The attacking force and the covering force are out of touch!"

Paul is from the special forces. If he is allowed to fight, it will be under the cover of heavy firepower. He will attack an enemy with solid buildings and intensive firepower, because the factory he is defending now does not only have a few terrorists.

The one occupied by the cloth elements, there are dozens of well-equipped PMCs here anyway.

It is impossible for the enemy not to know how strong the factory's defensive power is, so their style of play can only be caused by problems in coordination.

The king's defense people quickly gathered together, and then John hurriedly said: "What do you think the enemy wants to do?"

Patrick said without hesitation: "Suppress fire, send assault forces into the factory area, divide us, and deny us the opportunity to support each other, and then we can take down several firepower points one by one."

Paul said urgently: "Heavy artillery! Use heavy artillery to bombard the building, and then send infantry in to clear out the remaining enemies."

John said angrily: "This is not Russia, and it is not the army that is attacking!"

Paul said without hesitation: "Not the army? What else can those people outside be if they are not the army! Who else besides the army can kill so many people and still continue the attack!"

John said anxiously: "Just because they didn't retreat even after so many people died, it means they can't be the South African army. The South African army collapsed early after fighting like this. Alarm clock, do you think their fighting methods and formations resemble that country?"

of?"

Patrick said: "What I am thinking about is what weapons they will use to kill us in the building. If our enemy is the army, and it is the South African army, then what heavy weapons can they not use?"

Francisco said from the side: "Do you have to study these at this time?"

John said without hesitation: "Of course we have to study it. If we don't understand the enemy's firepower and tactics, how can we determine whether we should continue fighting or run away for our lives."

"It can't be the army! It can't be the army!"

Gao Guang finally spoke, and he said very confidently: "You can rest assured that even if there are South African soldiers outside, they will disguise themselves as other people. I have been assured that South Africa will never dispatch active soldiers to deal with Eli."

Gram Mining Company.”

After finishing speaking, Gao Guang breathed a sigh of relief and said: "Heavy weapons will not appear. Weapons such as tanks and artillery will never appear. If the enemy wants to use them, they can only use light weapons that can be used by individual soldiers."

John asked anxiously: "Why? Is there any basis for saying this?"

"Because Matara cannot afford to use troops and heavy weapons."

Gao Guang dared to say this because Danny assured him that South Africa would never send out troops, at least not openly.

This is originally just a matter of how to distribute the interests between Jacob, Matala, and Eric, and this kind of thing cannot be solved openly on the table.

Once heavy weapons that only the army can have are used, it will be announced to the world that this battle is South Africa's national act. For Matala, he really cannot bear the consequences, but the most important thing is that he cannot

It is necessary to send out the army.

But without the use of heavy weapons, the enemy's actions now are really unjustifiable.

Think about it, what else can the enemy do?

Patrick suddenly said: "Could it be a self-destructing truck?"

After staying in Iraq for a long time, Patrick first thought of blowing up the truck. This is indeed a very reasonable guess.

"Probably not, the movement was too big."

After Gao Guang finished speaking, he suddenly said: "107mm rocket launcher?"

When talking about 107mm rocket launcher, no need to mention the model, everyone present knows what it means.

AK47, RPG7, and Type 63 107mm rocket launcher are the three major artifacts used by poor guerrillas all over the world. What they have in common is that they are cheap, simple, easy to use, and effective.

This 107mm rocket launcher is responsible for the heavy firepower among the three artifacts. However, the effect of using a 107mm rocket launcher to hit solid buildings is not very good.

"It's impossible. How can the 107 rocket launcher be used to attack fortresses?"

John rejected Gao Guang's speculation, and then said with a confused look: "What other heavy firepower can an individual soldier use? If these people are sent by Matala, they have too many weapons at their disposal."

"Wait a minute!"

Gao Guang suddenly raised his left arm and made a listening gesture. Then he said with a look of astonishment: "Do you think the gunshots outside are confusing? The rhythm, intensity, and distance of the sounds are not like that.

It’s a suppressive firepower against us.”

Patrick said with an annoyed look: "What happened! I can't bear to have to rely on guesswork to judge the situation. Boss, let's go to the roof too!"

Francisco suddenly said: "The gunfire outside is a melee. If you ask me, the situation is very simple. The enemy is fighting within."

"Internal strife?"

Francisco shrugged and said: "For us, it's internal strife, for the enemy, it's a gang fight. We are originally a treasury waiting to be robbed, and they are originally two hostile parties, so when we encounter them, we must first

The winner is the one who has the right to rob us."

The words woke up the dreamer, and Gao Guang said in surprise: "That makes sense, then this is our chance!"

Now if we listen to the gunfire outside, the possibility of the enemy fighting within is even greater, because the gunfire is getting more intense, and there are even more explosions.

Patrick said anxiously: "Grenade! This is definitely the explosion of a grenade. The enemy has entered the distance where the grenade can be used."

Gao Guang looked at the office building closest to them. It was dozens of meters away, and gunshots were heard constantly. Although the distance was not too far, but when he saw the people on the roof dancing and shouting something, it was nothing.

can not hear.

Communication has been cut off, that's it, it's too troublesome.

Gao Guang was worried and said, "I can't make random guesses anymore. Go and see what's going on. I'll go to the roof."

No one dissuaded Gao Guang from going to the roof of the building because the situation was too chaotic and it would be more dangerous to not figure out the enemy's intentions than going to the roof of the building.

John said: "It's more dangerous to stay here, why don't we all go to the roof!"
