Mu Tianyu didn't look back, and continued to walk in front. He waved his hand and just said, "You can ask the two of them." ”

"Tell us about it!"

Jin Chen said modestly: "I'm still reflecting on my mistakes, you still have to ask Team Zhao!" ”

Jin Chen really didn't mean to be modest and prevaricated, he was indeed still reflecting in his heart, the two minutes that Mu Tianyu had punished himself just now really made him very heartbroken.

He inadvertently touched the bottom line that Mu Tianyu cared about the most about ensuring the safety of his comrades-in-arms and brothers when he was on a mission. Along the way, he kept thinking about it and remembered the journey they had walked together.

The students saw that Jin Chen had no intention of chatting with them, so they asked Zhao Zhennan again: "Team Zhao, can you tell us?" ”

Zhao Zhennan has also been thinking about why Mu Tianyu was able to lead the combat team, and at a young age, he won countless crucial battles and vicious battles!

Hearing the questions from his classmates, he saw that Jin Chen was still reflecting on himself, so he no longer threw the topic at him. Zhao Zhennan replied: "Do you see all kinds of thin ropes in the pocket of Captain Mu's clothes? In the pockets of the gold brigade, there are also many similar equipment items that are not prohibited by this military competition. ”

"Oh yes, we all saw it."

"Then the point of your problem comes. Do you remember those ropes that are all kinds of lightweight and not forbidden by the organizing committee? ”

"Remember, remember."

"If there is no ready-made steel cableway, Captain Namu will lead us to build one like that ourselves. Of course, it will be the Dyneema Ropeway. ”

"Oh, Dyneema rope, it's more than 10 times stronger than high-quality steel." One boy immediately remembered that the biggest advantage of the Dyneema rope is that it is both strong and soft, and it is very easy to carry.

Only then did Mu Tianyu say loudly: "Can anyone give us a detailed introduction to the Dyneema rope?" ”

The boy thought for a while, and then introduced: "Dyneema rope is a high-strength and high-modulus polyethylene fiber, and its physical properties are very good. It is a chemical gene that has a high degree of crystallinity and does not easily react with chemical agents. Therefore, it is resistant to water, moisture, chemicals, UV rays, and does not need to be treated with UV resistance. Corrosion resistance, acid and alkali resistance, excellent wear resistance, not only high modulus, but also soft, has a long flex life, the melting point of high-strength high-modulus polyethylene fiber is between 144 degrees and 152 degrees, and short-term exposure to 110 degrees environment will not cause serious performance degradation. ”

Mu Tianyu looked back at the boy again and said, "Yes, the memory can be compared with the Jin team." "Keep going.

Soon, Mu Tianyu and his team got 8 coordinate points. Forty-seven minutes have passed, less than a third. This made Jin Chen breathe a sigh of relief, and they finally regained the lost time.

Jin Chen said to the boy just now at this time: "Do you know the Kevlar rope?" ”

The boy shook his head.

Jin Chen said: "In fact, the ropes that Captain Mu often carries on his body are ropes with aromatic polyamide fibers, referred to as 'aramid' substances, commonly known as Kevlar ropes. This kind of rope is a rope commonly used by our firefighters, and it is also a rope commonly used by our soldiers. Because, Kevlar ropes are more resistant to fire and heat than Dyneema ropes, and modern body armor is also spun with Kevlar fiber. ”

"Oh." Several cadets seemed to have suddenly realized.

When Jin Chen spoke just now, he deliberately emphasized the word "firefighter", which made the two trainees who were a little prejudiced against firefighters at the beginning even more touched.

At the same time, Jin Chen may also have intended to say it to Zhao Zhennan. He always felt that Zhao Zhennan had looked down on firefighters since he first met a month ago.

Although he is now familiar with Mu Tianyu and Jin Chen, he gets along like brothers. And Zhao Zhennan now really admires Mu Tianyu and Jin Chen. He felt that these two were real professional soldiers, and they could continue to work miracles.

However, Jin Chen still felt that Zhao Zhennan was still prejudiced against the firefighters and the fire brigade, just like these students.

Of course, Zhao Zhennan also heard what Jin Chen meant, and he didn't deny it. Because, he does still have a little bit in his heart, and he doesn't admire the firefighters very much, at least he thinks that the firefighters are not as powerful as the troops they play with real guns and real guns.

He felt that Mu Tianyu and Jin Chen were just special cases. It doesn't exactly mean that the entire fire brigade can fight!

And Mu Tianyu, like Jin Chen, can feel that Zhao Zhennan's thoughts do not represent his thoughts alone, it is a very common idea.

Including all the participating school officials in the entire school officer competition, there are not a few people, who have a lot of complaints about the high scores of the firefighters when they are urgently assembled. They do not believe in their military qualities and will lose to firefighters who rarely touch real guns.

Therefore, Mu Tianyu and Jin Chen felt even more that they had a sense of mission, and they wanted to prove that China's fire brigade and China's fire officers were by no means vegetarians, but real soldiers with high military literacy.

In fact, Mu Tianyu feels that military quality is not something that can be possessed by touching the gun and ending the cannon every day. Rather, it is to be trained on the battlefield and on the fire.

In the past, soldiers had a heroic spirit that was not afraid of bloodshed and sacrifice, which was called "minor injuries do not leave the line of fire". This shows that the intensity of the battlefield is described as a fire field, called the line of fire.

To describe the war years, also called the era of war, it is also to use fire to describe the fierce war.

The fire is like a battlefield, which is often said and generally recognized.

Only by exercising in the flames of war and accepting the baptism of war can a soldier become a real soldier!

At present, there is a viewpoint that by intensifying training and turning exercises into actual combat, we can replace the edification of war.

Not really. The difference lies in the fact that it is difficult for a soldier to evolve successfully if he does not experience actual combat or war.

Training and exercises are psychologically incompatible with the battlefield and the fire ground. Psychologically, the commanders and fighters only have a similar sense of honor at most. And most people will not have the military soul forged by life and death and blood and sweat.

This kind of psychological difference cannot be changed by changing whether the water gun or the real gun is in the hand!

In other words, in terms of psychological quality, it is absolutely easy for a firefighter to reach the quality of a real soldier. Once they replace the water cannon with a loaded weapon. With just a little training, you can go to the battlefield and be invincible.

However, if a soldier in a field unit who has not fought in actual combat is trained and trained in his heart, he may not be able to go to the fire field, and his psychological quality may be difficult to prepare for to the point of really shedding blood and sacrificing his life.

That's the difference!
