This mine-laying work was mainly done by sappers, but Lao Hei still taught everyone some in advance; I took a student who graduated from the engineering department and stayed in school, and brought a few mines.

At that time, there were basically only ordinary explosive anti-infantry mines (AR), and there were no fragmentation (explosive mines), jumping (jumping mines), etc., not to mention anti-tank mines (AT).

There are no tricks in landmines, but there are many patterns in burying them, and the ordinary ones are just excavating on roads, bridges and other necessary roads, burying the mines, installing trigger devices, and then covering them with thin soil, and sprinkling the original skin dust on the top, so that people can not see anything unusual.

If there are no mines, a grenade can also be used, and the grenade can be made by opening the safety cover, connecting the string with a thin rope, and pulling the rope in a place that is not easy to find, such as grass.

Some people pretend to bury mines in the middle of the road, and the soil on the ground has traces of loosening, but in fact, the real mines are buried on the side of the road at the location of the fake mines.

The evasive mentality of catching people is to bury them in a place that you think is safe; Some roads deliberately expose "fake mines", and there is loosening of soil on the side of the road, but in fact there are real mines in the middle of the road, similar to the meaning of "there is no silver three hundred taels here".

There is also a method for demining, digging down a mine, thinking that it is platooned, but in fact, there is another one under this mine, commonly known as a child and mother mine.

There are also all kinds of trick mines, such as strange things on the ground, common cans, guns and ammunition, and even enemy corpses, etc., which can be part of the trick trigger device, which explodes as soon as it is moved.

The infantry on the battlefield was not equipped with mines, and there were many grenades used to make trick mines, and many of them were done in front of the defensive positions to prevent the enemy from touching the camp at night.

You can do some during the ambush to cause the phenomenon of flowering in the middle and closing around the perimeter, and hit the enemy's psychological defense line, which has a certain effect.

In addition, when retreating, do some tricks and tripping mines, causing certain casualties to the enemy, so as to delay the speed of the enemy's pursuit and disturb the enemy's psychology of taking advantage of the victory to pursue.

As for the mine array composed of all kinds of tripping mines, tricky mines, and mines buried in the ground, it is even more complicated, and the engineer science chief brought by Lao Hei does not have so much time to talk about it.

It just taught everyone some common mines, how to bury mines, how to identify dangers, and avoid dangers, as for removing mines, not professional sappers, no professional tools, try not to try, don't joke with your life.

Note: Some of the protagonists of modern film and television dramas stepped on landmines, and someone could help remove them, it was too artistic, and in reality, it was basically dead, and most of the mines were instantaneous, and they exploded as soon as they stepped on them.

The second is demining, the sappers don't know how many people were killed, not to mention that you are unprofessional, and you have to add a foot that you are stepping on, the human body can keep not moving for a long time in a posture, and it is generally a standing and lying down with a reliance, rather than a half-legged standing.

It is also necessary to maintain the pressure on the soles of the feet has always been the initial pressure, which is too difficult, so the probability of successful demining is very small. Third, among those who step on landmines, there are very few people who can have such a calm psychological quality.

……

In the following days, Lao Hei took everyone to soak in the defensive position every day, with the team as a unit, how to observe the front, signal transmission, evacuation and concealment, firepower allocation, crossfire, in-depth firepower, protection and defense, ammunition supply, active defense, etc......

The defensive position of a company-level unit actually allowed Lao Hei to make three in-depth defensive positions for the first line, the second line, and the third line; And if there aren't enough people? You have to give up and stick to something.

Each of them has to participate in various defensive positions and defensive tasks to learn, acting as observers, communicators, machine gun shooters, sub-machine gunners, rifle shooters, ammunition delivery soldiers, etc.

At the same time, another second squadron was also pulled to practice the attack, and after a few days, the two squadrons were reversed, the first squadron of the three dogs and their first squadron came to attack, and the second squadron defended, adding more melee (trench warfare) and night combat designs.

How to observe the enemy's situation during the attack, choose the route, advance step by step, how to suppress firepower, how to pass through the enemy's fire blockade area, how to assault the straggler line, how to jump into the trench, how to move and fight in the trench, and so on.

Anyway, a spear comes to a shield, and the two teams exchange and replace, learning and practicing, summarizing and improving, and how to crack it while coming up with a better way, and so on.

Compared with the fatigue of digging the position before, Sangou now feels much more interesting, and there are a lot more parts of the brain, and the courage on the battlefield is needed, and what is needed more is resourcefulness, and the combination of wisdom and courage is brave and resourceful, in order to become a qualified veteran and commander.

……

Lao Hei looked at the blank test paper (defensive position) with satisfaction, and said to everyone, this is your final exam room, and now you have practiced almost the same, you can review and summarize it yourself.

This final exam is mainly to test the formation change of infantry drills, the preliminary tactics of individual soldiers, night training, field attack and defense, rear defense service, and so on.

After a school year, after learning this, as an infantryman, you can basically fight alone and under command; There are two benchmarks for the results of this final assessment.

First, each person's results will be used as a reference for applying for sub-examinations in the second academic year; Second, there will be a division of grades, unqualified, assigned to a general team, continue to study these contents, and then take the test when the time comes, and enter the sub-subject study after passing the test, and postpone graduation.

Those who fail to pass the examination again and again will be assigned to the troops, but soldiers, not officers, and some will be assigned to other military organs, not front-line troops, and those who do logistics or something will definitely not be officers; Or they can simply be assigned to work in other non-military units.

Of course, there are extremely few such students, and some people are really not suitable for military affairs by nature, and no matter how much they practice the day after tomorrow, it is difficult to qualify, and they insist on being pushed to the battlefield, which will not only harm him, but also harm other comrades-in-arms.

However, this is also the strict standard of the Whampoa Military Academy at this stage, and as soon as the all-out war of resistance began, all standards were lowered, what entrance exams, intermediate assessments

Therefore, this examination is also very important, not to mention the veterans of the three corps, and the cadets of the other corps are also well aware of this importance, and they are all working hard to step up training.

In addition to outdoor classes, some indoor courses are also tested, such as Chinese language, arithmetic, physics and chemistry, exemplary order, ideology and politics, etc., and these results are calculated into the basic score of the sub-subject examination.

For example, mathematics, physics and chemistry will not be admitted to artillery and engineering, because these two disciplines require a lot of mathematical calculations.
