Qin Shuai put his heart into typing this row for Qin Chuan, and passed it on to his flying machine, telling him that this flying machine was dangerous, and he couldn't drive up so impulsively, and he couldn't joke with his own life, although those two military experts were really annoying, but it wasn't worth it.

Qin Chuan was also quite touched when he saw it, it was true, so he slowly lowered the aircraft, and put the parachute next to his seat, if he encountered a dangerous situation, he immediately took the parachute and parachuted.

After a few people drove the aircraft to slow down in the air for a few laps, they slowly landed on the ground without any abnormality, but Qin Chuan's aircraft was abnormal, and the tail slowly emitted black smoke like a burn, Qin Shuai hurriedly found someone to help him extinguish the fire first, and then check the condition inside, and the maintenance engineer said that these equipment were actually a little old.

While everyone was discussing what to do, they suddenly heard a rumbling sound from the depths of the clouds in the middle of the air, and someone shouted that it was not good, because aliens suddenly came to sneak attack.

They hurriedly returned to the sturdy small building, Qin Shuai and Qin Chuan took the lead in picking two sturdy flying machines and boarding them, ready to give them a counterattack, but the head of Qin gave an order to let them hide, because they were observing on the lookout, there were more than 10 alien attack fighters, this is not two flying machines can fight, so they can only be forced to retreat, and then return to the small building, just returned, the ground was blown out of several deep pits, Because they came with special shells.

It seems that this time they came with a kind of mentality of killing the net, so this weapon is extremely powerful, unlike the previous offensive weapons that still have a little leeway, because they may still want to capture some people below, but this time they don't even have the intention of capturing people, and directly want to blow up.

A commander was temporarily arranged at the scene to come over and tell everyone: "Commander Qin's intention is to let everyone retreat immediately, because this small building is also within their attack range, and we have protective covers in other places, so everyone should evacuate to a place with protective covers as soon as possible, and after we finish attacking and repelling them, the recruits will wait for Sergeant Qin in the conference room, and you will tell them how to use the new weapons." ”

It seems that Regiment Commander Qin has other tasks for the two of them to do, and they have received a special appointment order, which is a temporary training instructor for new soldiers.

Half an hour later, they repelled the aliens a few kilometers away as previously planned, but the danger was not completely removed, and Qin Shuai also entered the small conference room to tell the recruits something about weapons.

“…… We should know that weapons are tools used for attack and are therefore used for deterrence and defence. When a weapon is used effectively, it should follow the principle of maximizing the desired effect and minimizing collateral damage. Anything that can cause damage can be called a weapon. As long as it is used for attack, the weapon can be a simple wooden stick or a nuclear warhead. In our coalition army, we have a variety of weapons, and some soldiers are very familiar with them, but the new recruits are not familiar with some of our weapons and need to practice more. ”

“…… We also need to understand that weapons are closely related to the course of the war, and in the First World War, the defense based on trenches and machine gun groups proved to be superior to the offensive, so the First World War was mainly based on positional stalemate, and the defensive weapons were superior to the offensive weapons, and the maturity of submachine guns, artillery, and battleships dominated the battle...... The new weapons that appeared in the later period, such as tanks and airplanes, still have many imperfections, and can only be battlefield episodes. Later, the situation reversed, and the advantages of new land, sea, and air weapons, mainly tanks, aircraft, aircraft carriers, and submarines, were brought into play and dominated the battle situation, and this situation proved to be stronger in attack than in defense. ”

"Later, there was a great development of offensive and defensive weapons...... The growth of defensive weapons is often associated with peace. The maturity of radar technology and the maturity of various types of anti-tank weapons, defensive missiles, and anti-missile systems have all helped the offensive and defensive systems of weapons to gradually balance to defensive weapons. In addition to the maturity of missile technology, satellites, and positioning technology, the most important revolution in offensive weapons is the emergence of unmanned combat systems, and robot warfare may appear on this continent in the near future. ”

When it comes to military weapons, as well as their application to the ocean, Qin Shuai believes that the sea contains infinite energy, and if there is a new weapon system that can use the capabilities of the sea itself, it must be daunting. In addition, seawater is a conductor of electricity, and whether it can be completely changed by dropping bombs with ionization-like weapons that generate instantaneous extremely high voltage currents when entering the water, destroying the electronic equipment of the entire fleet and even the ship's hull personnel.

But this time, the military experts brought them a problem, asking them to explain the characteristics of various weapons to the recruits in the alliance army, but the alliance army has a lot of weapons, but they give very few samples, so they can only look for some of the recent ones they have used on the computer, and then when they are doing experiments, take pictures and play them to these recruits.

Since weapons were developed in the confrontation between spear and shield, they presented the characteristics of a wide variety of names and mutual compatibility, which brought many difficulties to the classification of weapons.

According to his role in the war, Qin Shuai divided into strategic weapons, campaign weapons, and tactical weapons. According to the degree and scope of destruction, it is divided into weapons of mass destruction and conventional weapons.

According to the types of arms used, he can be divided into army weapons, naval weapons, air force weapons, air defense force weapons, marine corps weapons, airborne troops weapons, and strategic missile force weapons.

There are so many theories popularized in the conference room at once, and there are so many models to show everyone, and many recruits are easily confused.

Qin Shuai divided them into 5 groups, and then summarized his views into 5 groups, and asked them to study a topic in each group, so that they were much easier, but the task assigned to them by Qin Regiment Commander was to let them get familiar with all the things as soon as possible, so these recruits had a headache because they couldn't remember it at all.

Qin Shuai asked them to speak, and the soldier representative said to Qin Shuai: "Thank you Sergeant Major Qin for introducing you so much, but after all, we are new soldiers, and we can't remember so much, and we don't know how to remember, but now it is stipulated above, let us remember all these things in the next few days......"
