On the second day, Qin Shuai took his soldiers to a military platform.

This platform was previously a tank base, set up in the mountains, because there are some special attack methods, and it is here that training is carried out by using tanks to attack the rocks to see if it is effective.

Its main purpose is mainly to train. But some soldiers at that time did not understand this strange tactic, so they fished for three days and dried their nets for two days, and then the leaders did not force them to do these trainings, and they began to pamper themselves, until a big war with aliens broke out, and they were outmatched by aliens on the battlefield, so they understood the importance of this training, but it was too late to regret it, so most of them were captured at that time.

There are still some traces of the battle at that time, as well as fragments of tanks, and some eliminated tanks in this place, so Qin Shuai introduced them one by one, and then told them some more important knowledge.

Suddenly, a soldier noticed that there was an armored car nearby, but it had not been used for many years, and it had become a lot old. There were still cobwebs hanging inside, so Qin Shuai stepped forward to help them clean it up together.

He used his ray device to beautify the car, and it looked as bright as ever, but whether it could be activated or not was another matter.

The soldier was very curious, so he asked Qin Shuai: "Sergeant Major, can you tell us about the armored car?" ”

Qin Shuai walked to the vicinity of the armored car with a smile, pointed to the various equipment on it, and then said to them: "The armored car is a variety of tracked or wheeled military vehicles with armor protection. …… Tanks are also a kind of tracked armored vehicles of armored vehicles, but in the habit they are usually classified separately due to their combat use, and armored vehicles mostly refer to vehicles with weaker protection and firepower than tanks. Armored vehicles have a high degree of off-road maneuverability, have a certain degree of protection and firepower, divided into two types: tracked and wheeled, generally equipped with small and medium-caliber artillery and machine guns, some are also equipped with anti-tank missiles, and the structure is composed of armored vehicle bodies, weapon systems, power plants, etc. ”

Qin Shuai explained carefully, and everyone listened carefully, so he walked to the side of several other vehicles and said, "...... In our coalition army, in order to enhance protection and facilitate the members to get out of the vehicle to fight, the front-mounted power plant scheme is mostly used. Later, with the birth of the tank, the armored vehicle with weak firepower, protection and cross-country characteristics lost its position as providing fire support for infantry on the battlefield, so it turned to other uses...... Tanks, which are also a type of armored vehicles, are usually classified separately for combat use in the custom, and armored vehicles mostly refer to vehicles with weaker protection and firepower than tanks......"

"Classified by use, it can be divided into infantry fighting vehicles and armored personnel carriers, armored personnel carriers provide armored protection for infantry and combat materiel, infantry fighting vehicles support infantry combat, and infantry fighting vehicles can also carry units, but the load capacity is greatly reduced......"

With Qin Shuai's order, everyone walked to the front of these armored equipment and began to repair according to Qin Shuai's maintenance drawing, they didn't know what Qin Shuai was going to do with these armors, because it looked relatively old, but Qin Shuai was quite confident, they felt that there was nothing to do anyway, it was better to practice their hands, so they were elated, and everyone cooperated with each other to repair it.

Through Qin Shuai's introduction, the soldiers knew that infantry fighting vehicles and armored personnel carriers have similar functions, both are armored vehicles for transporting infantry for mobile combat, and the difference between the two is that infantry fighting vehicles are more like light tanks that can carry troops, rather than armored vehicles with only a few machine guns.

There are also armored personnel carriers, also known as armored transport vehicles, which refer to armored vehicles that transport infantry on the battlefield, and generally have the characteristics of high speed, low protection and combat effectiveness. In addition to transporting infantry, the armored transport vehicle can also transport supplies or supplies, temporarily acting as an armored supply vehicle.

After everyone hurriedly finished the model arranged by Qin Shuai, a model that looked very godlike to an armored reconnaissance vehicle soon appeared.

Qin Shuai took this opportunity to introduce to everyone: "...... Armored vehicles equipped with reconnaissance equipment, which are faster but weaker than other armored vehicles, are mostly used for battlefield reconnaissance, and can generally be divided into two types: wheeled and tracked. An armoured command vehicle is a mobile command post with armor protection that provides the commander with supporting staff and other personnel to coordinate with the troops. Armored command vehicle...... The intent is to provide the command unit with rapid movement, continuous grasp of the situation and the issuance of orders, and provide some protection. You can follow what I have told you, come and visit each of our stations, in fact, this place used to design and manufacture these armored vehicles, but then due to some circumstances these designs were postponed and then disappeared, so you can see that there are a lot of sketches on the table, and these sketches are dusty......"

The soldiers looked in the direction that Qin Shuai pointed, and sure enough, as he said, no wonder Qin Shuai would rent here, on the one hand, they could use it as a dormitory, and on the other hand, they could produce the devices they needed here, and a lot of materials here, Qin Shuai had already bought them at a very low price, and they were bought at the price of scrap purchases. Most armoured command vehicles are converted from armoured personnel carriers, which have enlarged interior space to accommodate additional personnel, communications equipment, and other equipment. After arriving at the predetermined command location, some armored command vehicles have a canopy that can be extended out of the vehicle to further expand the space used by personnel.

Qin Shuai divided into three parts, one part stayed in the factory to continue the design and production, that is, to arrange the soldiers who were interested in these designs, the other group continued to observe the situation of the village chief, and another group followed him to overhaul the protective cover as soon as possible. There are varying degrees of damage these days, and the most damaged part is the part that is damaged by the children.

This place seems to correspond to a kind of energy field of children, but where does such a big energy field come from these children, this is what makes Qin Shuai puzzled.

On that day they received some gadgets on the spot, but they were just some toys for children, no more sharp than ordinary toys, and they could break part of the protective cover with a clang, but not sharp substances such as knives and scissors. Qin Shuai studied it for two days and didn't find anything unusual.

Qin Chuan felt that Qin Shuai was working too hard, so this time he stayed to cook.
