This incident is a big deal, and the main reason is that the reason why Shi Jin retired from the army was because of this incident that was eventually induced.

At that time, Xu Sanduo entered the army and it was almost a year old.

The annual assessment exercise of the 702nd regiment has begun!

The anti-infrared operation, which was highly valued by Gao Cheng, was exposed because of Xu Sanduo's stupid and mentally retarded behavior, and was criticized by the company commander Gao Cheng.

In order to help Xu Sanduo grow up as soon as possible, Shi Jin no longer always makes all kinds of mentally handicapped problems.

It was decided to improve Xu Sanduo's courage so that Xu Sanduo could be more confident, so as to quickly improve his performance and become a soldier that company commander Gao Cheng could look up to.

So during the daily maintenance of the infantry combat vehicle, when disassembling the tracks of the tank.

Shi Jin, who was originally cooperating with Wu Liuyi tacitly, asked Xu Sanduo to hit it with a hammer as soon as his brain was "dizzy", and he personally took the awl he was holding.

As a result, Xu Sanduo's hammer went down and directly broke his right palm.

This also led to Shi Jin, who was seriously injured in his right hand, couldn't take a gun with a lisuo, and his performance in the most important confrontation acting in the follow-up was very poor, and he was already very old, so there was almost no room for further improvement.

Shi Jin, who didn't want to stay in the army by relying on his relationship, finally had to choose to shed tears in the barracks.

This is one of the big regrets of "Soldier Assault"!

As the best squad leader of the Seventh Steel Company, and the Seventh Company of Steel is the best company of the 702nd Regiment, it is equivalent to saying that Shi Jin is the best squad leader of the 702nd Regiment.

With such good conditions as the foundation, Shi Jin will definitely not be retired if he is not injured.

The key to the culprit.

It was Xu Sanduo who made mistakes in anti-infrared operations that led to a series of subsequent bad butterfly effects, which led to Shi Jin's retirement soon.

Now that Class 3 has the thigh of Jackie Chan, this ending has been perfectly resolved.

In the end, the anti-infrared operation was a great success!

The way to stop it is actually not complicated, and Jackie Chan did not go to be a nanny for Xu Sanduo, staring at him all day long to see if he had eggs in his arms.

Rather, it is treated in the form of traditional Chinese medicine.

Traditional Chinese medicine treats the root cause, and Western medicine treats the disease.

Jackie Chan came out of the most fundamental core and solved this problem from the root.

That is, he personally found the company commander Gao Cheng, and analyzed the essence of infrared detection to Gao Cheng with his academic background from a top student of Capital University.

Plainly.

Infrared detection is not a perspective, it is just a means of observing thermal radiation.

The perspective in movies and TV series, ignoring the wall, can see all the heat sources in the house, purely for the artistic effect of shooting.

In fact, as long as there is something in between, and there is no contact between the two sides.

That is, there is no heat transfer!

Even a thin piece of tin foil with good sensibility can make infrared detection blind.

Even if you block a piece of transparent glass in the middle, the human eye can see it clearly, and there will be no reaction from the infrared detection.

Of course.

If the shelter is not sealed, but there is a certain gap in the middle, even if the gap is small, it is impossible to distinguish with the naked eye.

Such as tents, camouflage nets, bushes, etc.

These have gaps of different sizes in between, through which thermal radiation can come out, and naturally they will also be seen by infrared monitoring.

In the original plot, many three will be found, and one is slightly artistic.

The cooking class boiled eggs and sent them over, put them there and ate them for so long, and finally was kicked in Xu Sanduo's arms, and the temperature was not much higher than the body temperature.

If this egg can be detected, then the steel seven will definitely be exposed.

The second is the lack of culture.

In these years, college students are treasures, high school students are talents, and the most people who come to the army are junior high school students.

Don't look at the Seventh Gang Company, which is known as the most elite reconnaissance company, but in fact, everyone, including the high-level personnel, does not know what the mechanism of infrared detection is.

At most, infrared detection can see the heat source and can tell where something hotter than the environment is.

The others are completely unaware, and they are cramming, and there is no divergence at all.

Otherwise, Gao Cheng would not have said that Shi Jin didn't even dare to drink hot water in order to avoid being found during the last anti-infrared operation.

Even Chang Gaocheng didn't remind him!

Because their cultural level is too low, they don't know how to solve it "smartly", and they only know how to use dead methods to copy it.

In the case of not knowing whether it is useful or not, I can only make a stupid choice to do it first and then talk about it.

Jackie Chan proposed to let Gao Cheng buy two things, four things that are cheap and easy to use-

Plastic film, tin foil, green paint and glue!

The plastic film is cut and glued with glue to make a whole with an area of more than 20 square meters, which is enough to cover the size of an infantry chariot.

Such plastic sheeting, one piece per class, a total of six pieces.

Then brush the green paint upwards, paint all the plastic sheets green, and then take some loess and rub it on it, and it becomes a jungle camouflage.

Plastic film is not enough to insulate it.

After all, although heat transfer cannot be conducted directly, air can also be used as a conduction medium.

Originally, the Seventh Company of Steel was just digging a hole underneath, using camouflage cloth, plus various branches with leaves, and covering it as a camouflage.

There are actually a lot of gaps in the middle, and the heat can be well dissipated, and the overall temperature will not be raised.

Now that the plastic film has been replaced and it has become a sealed state, so many people in a class are nested in a narrow space, and the overall internal temperature will quickly increase in the case of poor airtight heat dissipation.

The drill takes a long time, and it may take half an hour to dodge.

The plastic film does not have too strong thermal insulation ability, and it is okay for a minute or two, but once the time is exceeded, the plastic film will become hot, increasing the possibility of being detected.

Therefore, the plastic film is mainly used as a camouflage, so that the tin foil can be unfolded.

There is also a reflection that blocks the tin foil.

Tin foil has a very good thermal insulation effect, the price is cheap and affordable, it is simply the natural enemy of infrared detection, and the disadvantage is that it is too brittle and easy to break.

Jackie Chan is ready to paste the plastic film into a whole to solve this only drawback.

Glue the tin foil to the plastic film, without the green camouflage side, relying on the toughness of the plastic film to make the foil easily unfold without being torn.

When it was time for the anti-infrared operation, cover this Jackie Chan's special anti-infrared isolation film, and then cover the camouflage net and various branches with leaves on the outermost part for camouflage.

The easy-to-use and cheap anti-infrared camouflage net is so easy to complete.

The person hiding inside is not to mention carrying an egg, even if he runs in with a pot of boiling water to hide, the infrared heat source detection of the helicopter cannot find it.

Gao Cheng has always liked Jackie Chan very much, and seeing Jackie Chan say so much, he is the truth.

Plus the name of Capital University is too big!

That's a rare talent in the division, and he doesn't have the qualifications to speak in terms of culture.

Without saying a word, Gao Cheng called the secretary and asked him to take Jackie Chan to the street and buy back the four materials he needed.

In the end, during the anti-infrared operation of the assessment exercise, the three armed helicopters flew around in the sky, as if they were on the steel seven bars, and they did not believe that there was no reaction.

I searched back and forth four or five times, but I didn't find anyone from the Seventh Company of Gang.

Not to mention a human being, not even a single hair.

In the end, it can only be fruitless.

The Seventh Steel Company was also highly praised by the exercise base camp for its outstanding achievements.

The division commander also personally called over, praised Gao Cheng fiercely, and clearly told Gao Cheng that the anti-infrared effect of the Seventh Steel Company was the best among dozens of companies in the division.

He also asked Gao Cheng to personally go to the division headquarters to share his skills and experience in anti-infrared operations.

Let all the grassroots units of the whole infantry division learn from the Seventh Steel Company.

Gao Cheng is terrible now!

Not only among the 15 company commanders of the 702nd Regiment, he can walk sideways with his waist crossed, but even among the dozens of company commanders of the infantry division, he Gao Cheng also walks with his head held high.

For Jackie Chan, who helped him earn a good face, he fell in love with him even more to the bone.

If it weren't for Jackie Chan's height, he would definitely hug and kiss him!
