For all the military and special forces or SWAT, the biggest headache for them is fighting in a confined space.

Because in the confined space there are enemies waiting for battle, hidden snipers, undetectable traps, and all sorts of other dangers.

A successful fight against terrorism requires a well-trained team to deal with it.

The most difficult part of indoor CQB operations is to engage the enemy as covertly as possible.

In most cases, the enemy will be able to anticipate where you are entering, and set up a defensive position or formation for that location, and greet you with strong fire where you enter.

When Chen Quan was in the commando, he experienced this kind of indoor CQB training.

The reason why it is said that in indoor close-range combat, the brave wins when they meet on a narrow road, is because there are three points that must be achieved in indoor close-range combat.

Swift, quiet and fierce.

Swiftness means that you move quickly, effectively, and your gaze is only focused on what is in front of you.

Silence, for the most dangerous situations, is your best defense.

Fierceness means that once the enemy is engaged, the enemy's arrogance must be suppressed with the most aggressive posture.

Chen Quan quickly rushed to the top of the staircase where the third floor and the second floor intersected, leaning his back against the wall, which was a safe place, in technical terms, a safety corner.

The so-called safety corner is a safe area between the angle of the enemy's gun line and the corner of the wall.

That is, in this safe area, there is no way for the enemy to hit you.

Once you've taken the safety corner, you have two options.

The first way is to shoot straight through the corner. But there is a premise for this method, that is, you have to confirm the enemy's location beforehand, and the enemy has not noticed you.

The second method is to cut the corners.

The first time to enter the safe range is to stick to the wall. After making sure your enemies don't stick around the corners, slowly slide an arc around.

At this point, the enemy's safe angle in the target area will slowly decrease until you have turned the entire corner, and the target area will be clear.

As for how to deal with the enemy's attack when cutting the corner, it depends on your own reflexes.

Chen Quan chose the second method, generally speaking, indoor close-range combat is cooperated by teammates, but he is now a single soldier, and he can only choose the safest method.

Moving slowly against the wall, the muzzle of the gun moving with the line of sight.

Fortunately, it was night, which brought Chen Quan a lot of advantages, and he walked out with light cross steps, slowly expanding his perspective.

He listened intently, but there was no movement below, and the rustling sound was gone.

In the yellow-green world, no one was found, and when he completely walked to the stairs on the second floor, Chen Quan stopped and continued to move forward.

First of all, check all the halls on the second floor, there is almost no place to hide people, so it is very likely that this person is hiding around the corner of the staircase.

In some film and television works, this kind of indoor close-range combat is often the most exciting in the corner, and the protagonist can kill the enemy with a single shot when he turns a corner.

It looks simply handsome and unbeatable.

However, in the face of such an environment, it is basically impossible to kill the enemy in such a smooth manner.

No matter how much you train in close combat indoors, no matter how high the tacit cooperation between the team members is, you don't dare to say that you can be so powerful when you really fight.

Because, just as there are no two identical leaves in the world, there are no two identical indoor close-quarters combat.

Indoor close-quarters combat is a kind of battle that goes to heaven and hell step by step, life and death step by step.

The enemy is around the corner, if it is not at this kind of staircase, then Chen Quan will consider going directly to kill the other party in an instant.

But standing at the top of a staircase like this, which didn't even have a topography advantage, he wasn't going to do it.

"Whew!"

Chen Quan pulled out a grenade and held it in his hand for a delay of three seconds, generally speaking, the fuse of the grenade is about five seconds.

"Boom-"

He flicked the grenade out, and it rolled on the ground and into the corner.

"Boom-"

As soon as two seconds passed, the grenade exploded suddenly, and Chen Quan felt the stairs vibrate, and a shock wave was rushing in the air.

The grenade exploded without the slightest pause, followed by another grenade.

"Boom-"

This is the grenade that Chen Quan tied to the door of the corridor outside the second floor, as soon as these two grenades explode, they formed a front and rear pinch, even if the person hiding in the corner of the wall can hide no matter how he can, it is estimated that it will be useless.

When the grenade exploded, Chen Quan did not hesitate at all, and rushed down directly with a shotgun.

It's the same as when he first skims in a few shock bombs after breaking down the door in an indoor close-range battle, and blows up the people inside, so he can go in and harvest.

It's just that Chen Quan threw a grenade, which is not as simple as blowing up the stun, and he can directly blow up the other party.

After Chen Quan rushed to the second floor, he saw that the set of sofas, tables and chairs on the second floor had been blown up by grenades, and at the same time, there were corpses lying on the ground without an arm or half a leg.

Fortunately, it was seen from the yellow-green world of night vision devices, and the scene was very bloody for a while.

At the same time, Chen Quan also heard the broadcast on the island, and the number of his kills increased again......

"Huh! No, how can it be three? ”

Chen Quan saw that three had been added to the virtual screen, and it became [27/100].

In this house, Chen Quan only killed two, could it be said that the grenade set up somewhere killed another one?

Regardless of where you get killed, it's a good thing that the number of kills has increased anyway.

Just as Chen Quan wanted to leave, he suddenly found that the door on the second floor had been blown up by a grenade, and there was a big opening.

Outside the door was a kneeling man with a panel stuck around his neck.

This...... There's still a guy hiding outside.,Good guy.,Directly inserted into the neck by the door panel.,It is estimated that this person will not think of it until he dies.,I wanted to be a yin person but was punished by the door panel.。

Is this an inadvertent Q?

Triple kill!

Now that the building was being shot and exploded, Chen Quan decided to evacuate the place.

Making such a big move will definitely attract other people to come and do things.

"The countdown is over, the poisonous fog is spreading, the safe area is reduced by 100 meters, and the countdown to the next poisonous fog spreading [4:59]."

At this time, the island radio sounded again, and there were only 100 meters left in the safe area.

One hundred meters!

Just about to walk out, Chen Quan immediately looked at the map, this special safe area suddenly deflected, look at the flashing white circle, and after the circle is over, he will be out of the circle.

You have to run to a safe area quickly, if you stay outside, you will probably die faster, God knows what kind of poisonous fog this is.

This is not a game, and there is no durability state, once a person is poisoned, it is estimated that it will be wasted.
