Naturally, there will be various forms of performances, which are actually live-fire drills.

There is a stop to shoot in formation, and the combat effectiveness in this mode can be guaranteed, especially the terrifying rate of fire of the machine gun, and you can even see a flash of fire shooting out when the bullet is shot, and then there is a puff of dust on the opposite side.

And the soldiers in the shooting hole are not idle, constantly shooting around, and the firepower is naturally inferior, but as a supplement, it can still play a certain role.

Besides, even if the enemy is close, he can only be helpless.

The knife can't cut in, the arrow can't pierce it, and even if you get close, the infantry in the surrounding armored vehicles will shoot at a fixed point.

Of course, although the steel plate is thick, the distance is too close, and it will not be fun if it is shot through, so according to the requirements, it is generally the armored vehicle behind to shoot, or to make sure that your bullet does not hit the position on the armored vehicle for shooting supplement.

Then there's the mobile shot, which looks the most sensitive, but the effect is also very sensitive, and the accuracy plummets, almost no accuracy at all.

But a line pulled out, in the face of enemy clusters, the effect is still obvious.

The two forms of performance are very enjoyable to watch, but they also give the impression that this is not the most perfect armored unit.

But no one said anything, after all, this batch of armored vehicles has only arrived in the army for less than two months, and they are just getting acquainted with it, and they dare not say that they have completely figured it out.

But even so, it is enough to use it on the battlefield now.

It can even be said without any scruples that the current military level of Datang has been ahead of the world for at least a thousand years.

Of course, the machine guns are all on the car, will the artillery be far away?

Maybe it will take a while for the artillery, but the rocket artillery is already on the car, but the residual temperature of the rocket artillery launch is too high, and the impact on the vehicle is too great, well, there is no effect.

This so-called impact only needs to move the wheels forward a little, and correspondingly put the position of the rocket artillery a little back, plus the protection of the bottom of the car, the impact can be minimized.

And now, Qu Tuquan has also completely agreed with Cheng Zhijie's words, the combat effectiveness of such a regiment does exceed that of an ordinary full-formed regiment.

Although it may be inferior in terms of individual tactics, in terms of firepower, maneuverability, and suppression ability, the armored forces are completely victorious.

Because the engineering troops have to be built, a construction site is often paved for a long time.

Conventional infantry takes a long time just to move, but armored forces do not have this problem.

In addition, they don't have to build a defense line at all, the armored vehicles themselves are a line of defense, and when a few armored vehicles go there, the bullets are whizzing, and even if it is a cavalry cluster, it is difficult to rush over.

It is also possible to maximize the firepower by standing with the rear of the car diagonally facing the opponent, so that one machine gun and four rifles can be fired at the same time.

It's good, it's powerful.

"The task of the engineer is very difficult, you have to be mentally prepared." After watching the drill, Li Chengguang said to Qu Tuquan.

Although he had not personally visited the Western Regions, it was very difficult according to the feedback that came back.

It's not as simple as building a railway inside Datang, as for building a railway to Gaoshan Province, hehe, Li Yuanji cut it directly, and the reason is also very good, he doesn't have that ability.

Why don't you have that ability? The ministers were depressed, everyone was depressed.

But whether the province of Gaoshan repairs the railway or not, in fact, everyone does not care, because there is no need, there are few people there, and there is not much economic significance in building the railway, as for the strategic significance, there are mountains everywhere, what strategic significance do you want?

Could it be that the countries in the south will climb over the impassable mountains to sneak attack? What about a sneak attack? Will they be able to beat the garrison?

"Your Highness, rest assured, the last general is ready." Qu Tuquan hurriedly expressed his position.

Li Chengguang smiled slightly, seeing Qu Tuquan's confident performance, he really couldn't bear to hit him, but asked people to hand Qu Tuquan the news he had gathered so far.

The first section of the railway is very simple, it doesn't need too much planning at all, this section of the road Tang people often walked before, that is, along the official road to repair it, the biggest difficulty is nothing more than to erect a few railway bridges, this is not a problem, now the Tang people are already very familiar with the bridge, except for the terrible river of the big river It takes a little longer, and the rest can be completed within a year or two.

The first section of the target is, of course, starting from Chang'an, along Qizhou, Longzhou, Lanzhou, Ganzhou to Yumen Pass, there is not too much difficulty on the way, and the route is also very well planned.

But the second section is more difficult, after getting out of the Yumen Pass, the terrain behind is more complicated, there are desert areas, these have to be bypassed, don't worry about this, but the Gobi region will not spare.

There are also some mountains, this is also more painful, some mountains are not able to go around at all, around it, you have to build dozens of miles, or even hundreds of miles of railway, which is not in the construction, or in the later operation, will waste a lot of time.

So, the advice given is to make holes and tunnels according to the situation.

But the tunnel is so easy to play?

The soil mountain is easier to fight, but it is also more dangerous, not to mention whether there will be a collapse when the hole is punched, when the train passes, it will produce a lot of vibration, if the soil and mountain are not strong enough, it will be fatal to collapse at this time.

The stone mountain can avoid this problem, but if the stone mountain is hit, it is better to say that it is shorter, and what if it is longer?

"Specifically, you can communicate with the technicians, what the father means depends on the situation, if you can, you can build a tunnel, if it takes too long and consumes too much manpower, you will find a way to build a bridge and cross this mountain." Li Chengguang naturally knew the difficulty, and Li Yuanji also knew it, so he gave such a suggestion.

Of course, building bridges is not a panacea, and the difference between some mountains and the ground has reached thousands of meters, so you can't build a bridge thousands of meters high, right? Therefore, Li Yuanji's view is that if you can go around, if you go around too far, you should find a place with less difficulty to build.

"The last general will definitely complete the task." Qu Tuquan gritted his teeth, this was the first time he came into contact with his next task, which was a little surprising, but it seemed to be reasonable.

However, in the face of this difficulty, Qu Tuquan did not retreat.

At this time, retreat a hair, first from Chang'an to repair it, now even Chang'an has not come out, anxious about a wool?

Will there be a better way to be interested?

Of course, Qu Tuquan would never have thought that because of this experience, he would be called the first person of the Han railway, and Li Yuanji would be called an infrastructure madman.
