This safe distance is also said to be true, taking into account the power of modern 155-mm self-propelled howitzers, as well as its coverage.

The domestic 155 mm caliber self-propelled howitzer is very safe at a distance of about 15 kilometers, with an error of about 50 meters from the shell and a radius of 50 meters.

Of course, there is no 100% guarantee for anything, and in fact, there have been places where live ammunition has been used in previous exercises, although such large-caliber artillery has not been used.

But the explosion of a small caliber is closer.

Actually, there are dangers, but if you are afraid of danger, you don't have to go to the battlefield.

However, when Jiang Yanhai typed this report, there was still some shock on it, although he had listed all the detailed security measures in it, but they still felt a little unbelievable, in fact, you have to talk about security.

This is even safer than when training them and flying directly on their heads with live ammunition, after all, when the bullets float on their heads, no one can guarantee that they will not look up directly after a brain twitch, that is really looking for death.

And such shells are actually prepared.

"And what are you going to do when you're ready up close?" At this moment, it was not someone from the regiment who asked Jiang Yanhai, nor Fan Tianlei, but a colonel about fifty years old in the war zone, and Jiang Yanhai did not know the specific position.

"Artillery shells have different fuzes, modify the self-excitation fuse, close range outside the safety distance, the use of autonomous remote excitation, with the dud bullets fired by distant artillery brothers, directly self-detonated, so that we can determine the explosion location of the shell, and then we can artificially control the safety distance." Jiang Yanhai said very simply.

The 155-mm artillery shell itself has multiple fuzes, and different fuzes are used to perform different combat missions, of course, it is not difficult to modify the fuze of the shell, and there is nothing difficult for the professional military industrial group to give you customized production.

"What are you...... I really thought of everything.,What about this.,I can report your information.。 But whether it needs to be approved or not, that's not for me to decide. The colonel said helplessly.

"Yes! Heads! Jiang Yanhai said very seriously.

For example, other induction-triggered mines are easy to say, including the soldiers of the Wolf Tooth Special Operations Brigade who pretend to be chasing soldiers can also deal with them, only that the danger of artillery shells seems to be relatively large, but in fact, it can be controlled.

After all, the real shells are all 500 meters away, and the shells within other ranges are fake, and the warheads that come over are all duds that do not explode.

There's nothing difficult about it.

As for the danger, it is much less dangerous than playing with a gun as usual, and it is all under control.

As for the question of that wood.

There's no way, blow it up, blow it up and let them see what the real battlefield looks like.

Not to mention anything else, the power of a 155 mm howitzer after explosion can blow up a large crater with a depth of nearly 2 meters and a diameter of about 6-8 meters.

If it was a large-caliber howitzer covered fire, it was possible to survive the covered attack of artillery before, but now it is ...... Too few survive.

Shock waves, shrapnel kills, etc. are enough, killing people is simply a matter of minutes, if you are hit at close range, then really, the rest of the estimate is just a few pieces of clothes and the like, definitely the kind of dead without a corpse.

Let them see different corpses in the front, and even let them directly use these prop corpses as shooting objects in some sports shooting, just to make their psychology grow as soon as possible.

And when they go to this training ground, it's training how they react in an emergency.

However, there can't be too many squads for one-time training at this training ground, so it can be expanded to train two combat teams at once, that is, 24 people.

More than 300 people also have to play a dozen times to be able to go around in a circle.

But it doesn't matter, it's nothing more than a matter of consuming a little shell, and it is impossible for this shell to consume much, because this shell will only have two guns to shoot at that time, and it is impossible to play with artillery fire coverage.

After all, the cost of a shell is about 20,000 yuan, which is also a real money. Anyway, the artillery has shooting training every year, so I guess I gave them shooting training at that time.

In fact, Jiang Yanhai thought about whether his fantasy simulation battle system could be played in reality, and the most likely thing was the game, such as the VR game that he is currently proficient in, but the visual effects alone are useless.

The visual effects VR version can do it, Jiang Yanhai's own first-person perspective is enough to train countless soldiers, mainly because of the training mechanism, for example, if a soldier's body performs tactical movements, this is extremely difficult.

In fact, he has conceived a lot of schemes, such as a full set of full-body strength feedback suits, which can give you enough strength feedback for different parts of the body, simulating the different pain caused by the impact of the force when you pounce on the ground during holographic training.

These can be simulated.

But you can't let him mess around on the playground, can you?

It is necessary to control him in a fixed instrument, but in a fixed instrument, it is difficult to control him within a certain range similar to running, tactical maneuvers, etc.

He even thought carefully about some of the sci-fi movies he'd watched, like the one in Ready Player One, but that was too rudimentary to achieve.

The other is the method used by the giant mecha in the Pacific Rim, but that method actually only solves the problem of running, and when it makes various maneuvers, it is actually a maneuver made by the mecha entity outside.

But in fact, Pacific Rim is a solution, the problem is that you have to do a 360-degree force feedback device, which can only be said to be difficult.

As for what is more high-end, a real holographic game, similar to Avatar, something that puts your spirit directly into the virtual world, don't think about it, it's impossible.

So, for now, it's a dead knot.

This is also the best way to simulate the battlefield environment realistically. However, the jungle environment can only be simulated once, and the real big tree is the first time it is simulated, and as for the later time, you can only directly install some fake bushes to decorate the entire hillside.
