The weather in August, summer has not yet passed, the air is full of dry heat, even in the mountains, Zheng Long and others are sweating profusely.

Zheng Long and his special operations battalion have been stationed in the mountains for five days, and in these five days, Zheng Long has led everyone to train, practice physical strength, and practice endurance, and sit down at night to listen to Zheng Long explain to them various tactical applications and special cases of attacking tough battles, mountain warfare, and defensive warfare.

In five days, most of the soldiers have lost weight, but they are not tired after training, everyone looks extremely full of mental strength, they are all soldiers who have experienced a hundred battles, after Zheng Long's scientific training, many people seem to be a lot more profitable.

At six o'clock in the morning, just after dawn, five hundred people stood straight in the open space in the barren mountains, waiting for Zheng Long's order.

These 500 people have just come back from running five kilometers, from the beginning of entering the mountains, their work and rest are very regular, get up at five o'clock and run five kilometers first, and then have breakfast, after listening to Zheng Long's class in the evening, they rest on time at ten o'clock, there is no sleeping bag, they all sleep under the body with dead branches, there is a stream next to it, and they can take a cold shower at night.

"Today I will teach you how to lay out the tricks." Zheng Long glanced around as usual, and the crowd opened his mouth and said, "Tricky mines, to put it simply, are more complex mines, mines that are not easy to disassemble, and there are many specific methods. ”

Mines are a kind of low-cost weapons, is buried in the ground or placed on the surface of a kind of weapon, the earliest history of mines in our country appeared in the Ming Dynasty, in 1903, Russia (now Russia) invented a more professional mine, also called anti-infantry mine.

Mines can be roughly divided into two categories, the first is to defend against infantry mines, and the second is to defend against tanker mines; there are many specific ways to use mines, the most famous of which are mines, which are more difficult to disassemble and more dangerous than mines, especially in the 21st century, mines are even more varied, and a teacup, a pen, or even a watch may be mines, which make people unable to guard against them.

At this time, there was no such advanced science and technology, and the treacherous thunder was mainly arranged by human wisdom, such as double thunder, fire thunder, poisonous thunder, and so on.

At this time, mines are more often caused by low-cost mines, and mines are divided into stepping hair, taspering, pulling, pointing, jumping, fragmentation, and so on.

As the name suggests, two mines are two mines together, and if only one is found and the other is not taken into account during mine clearance, the two will explode together, thus causing greater losses to the enemy.

It is very particular and methodical to connect the two mines in series, because the mines are filled with black powder, which is a dangerous item and is very easy to explode, so if you want to connect the two mines in series, you must ensure that the black powder will not explode, and secondly, the detonating equipment of the two mines must be connected together to ensure that if one is moved, the other will definitely explode.

During World War II, landmines were used quite extensively, and were used by various countries, and the preservation period of landmines was relatively long, and the longest could be buried deep in the ground for 50 years, so up to now, there are still many countries from time to time that landmines hurt people, so now, the international conventions have clearly stipulated that mines are not allowed to be used, but during the War of Resistance Against Japanese Aggression, in the face of the ferocious Japanese army, mines were weapons that had to be used, and they could arrange defense areas, and they could also delay the pace of the Japanese army when retreating, so mines were at that time. It is a must-use thing.

Putting these aside for the time being, let's just say that after Zheng Long finished explaining, he took the mine handed over by Long's article and began to explain, while explaining and doing hands-on operation, it is easy to say, but when it comes to real operation, there are many places that need to be paid attention to, and Zheng Long has to explain it again and again several times to rest assured.

Thirty minutes later, Zheng Long finished explaining, and at the same time the double thunder in his hand was also arranged, and after confirming that everyone knew the precautions, Zheng Long dismantled the double thunder again, divided it into two mines, and began to let everyone step forward one by one to arrange it.

Fortunately, all the people present have come into contact with such things as mines, and as long as they understand the matters that need attention, there is no difficulty left, and all they need is to commission the speed of arranging double thunders, and that's it.

All morning, Zheng Long watched the soldiers go to set up the double thunder, Zheng Long looked very carefully, he was deeply afraid that some careless soldiers had sounded two mines, although the probability of this happening was very good, but Zheng Long was still not at ease.

Fortunately, the people in the first battalion are all veterans, the methods are in place, and they master it very quickly, at eleven o'clock in the morning, the entire five hours, all the people have started to do it and know it by heart.

It was only at this time that Zheng Long's nerves relaxed, and after ordering everyone to rest in place, he walked to the side alone, lit a cigarette, and smoked slowly.

After thinking for a long time, Zheng Long sighed, he knew that the nearest base of the Japanese army had to be 100 kilometers away, and it was too risky to march in a hurry to carry out a sneak attack, and the cost performance was not high, so after thinking about it, Zheng Long could only give up.

An hour and a half later, after all the people of the first battalion had lunch, they began to practice actual combat training, the so-called lunch, that is, the dry food and the game caught with the boiled stream water was a lunch, the stream water at that time did not have so many impurities, and after boiling, it could be quoted and the current mineral water was not worse than this, and it was sweeter.

Actual combat training is two people against each other, using branches instead of bayonets to practice bayonet skills, there is no empty pack of ammunition, so there is no way to carry out serious drills, the use of bayonet skills is very necessary, as long as it is a war, it must involve the fight bayonet, especially one side of the attack, one side of the fight bayonet is very necessary, the bayonet is used well, sometimes it can even determine the direction of a battle.

This was followed by shooting practice, where one person only had five bullets, and he practiced his marksmanship with Hanyang-made to maintain his feel so that he could be put on the battlefield at any time.

A week, a full seven days, Zheng Long led the team in the mountains for seven days to lead the team to train, seven days down, everyone not to say reborn, at least everyone's mental outlook has been very different, and then you need to continue to maintain training and participate in a lot of actual combat, the one who survived is the sharp knife soldiers of the special battalion!

Ready to go, the blade is about to take shape!
