Regardless of whether they have ever flown in an airplane or not, the vast majority of people know that the noise of this jet engine is deafening, but they do not know that compared with fighter planes and attack aircraft, the noise emitted by this civilian engine is at most a sheep's cry.

Relatively light, very gentle.

On the other hand, the roar of the military aircraft engine is like a raging beast, especially the noise during take-off can not only make the window glass two or three white meters away "clang, clang", and even make the cement floor and the walls of nearby houses vibrate!

Why is the runway of a military airport relatively thicker than that of a civilian airport, generally half a meter in warm areas and one meter in severe cold areas?

Some people say that it is not only necessary to guard against the impact of aircraft take-off and landing and the impact of the climate, but also the cause of this vibration: if it is too thin, the vibration caused by the noise of military aircraft taking off can cause dark damage to the thinner reinforced concrete runway, and even lead to cracks and damage over time.

An A-37 attack plane in the base is undergoing engine tests, and its engine power is not large, and the throttle is not increased to the maximum, but this deafening noise is enough to make people's ears nervous from a distance of 100 meters.

Civilian engines have to consider noise pollution, and military engines that serve to kill people obviously don't have this concern.

The ground staff who are waiting for the "lion cubs" on the tarmac are basically wearing anti-noise headphones, otherwise the noise will be uncomfortable, and the mortar fire and the whistling sound of shells falling that may be heard in this quiet situation will not be heard at all, until the shells explode...

I guess I still don't feel anything, because they died in an instant!

The radius of the dense kill zone of anti-personnel grenades fired by the M29 has reached 22 meters, and the shrapnel flies farther, and if you are unlucky, you will be killed from a distance of 100 meters!

This is not a film and television drama that is shoddyly made and directed by a brick family, and large-caliber shells are still flying two or three meters away.

It's going to blow people to pieces!

An 81-mm anti-personnel grenade detonates on a concrete tarmac with such an ideal impact point, and the lethality is well released: the crater is shallow, the instantaneous message does not allow the shell to burrow into the soil for half a section before exploding, and the shrapnel and shock wave are not swallowed up by the ground too much, and are basically released in the air.

Due to the high ballistics characteristic of mortars, the shells land at almost a vertical angle, detonate vertically, and there are almost no long or short lines in the dense kill zone.

People in the circle 22 meters from the point of impact had about the same chance of not being hit by shrapnel as they were in the lottery jackpot, and those who were far away were about 10 meters from the point of explosion, and close to each other, a group of people was still caught between two shells that exploded almost simultaneously.

Flesh and blood flew everywhere, and immediately died, and a few people who were unlucky still died without corpses, and were blown up and disintegrated!

Two shells reimbursed almost all the living people in this area, and as for the two fighters, they were no better, they became sieves, especially the one that was sandwiched in the middle by two shells, which was enough for it to scrap and dismantle parts as a supplier of accessories.

However, it is not only a matter of scrapping, after an interval of two seconds, two shells exploded nearby: this M29 mortar can reach a rate of fire of 30 rounds per minute in the first minute of rapid fire, which will allow Qin Jiandong to deliberately control the speed of shelling, just smash all the shells out within two minutes.

At most, two minutes will hang zero, even if the airport garrison is all immortals, it is impossible to threaten the safety of Pavel and others.

The first shell stabilized the gun, and then the change in the temperature of the barrel caused a longitudinal deviation of fifty or sixty meters from the impact point of the second shell, but it was still in the position of the helipad of the entire row.

Qin Jiandong and the others couldn't see the impact point, but they had shell observers report the change in the impact point: after firing 5 rounds of shells, Qin Jiandong quickly fine-tuned the gun mount, and the sixth shell returned to the vicinity of the impact point of the first shell and smashed directly on the wing of a "lion cub"!

The entire wing was blown up in an instant, the aviation fuel was ignited at the same time, and the plane was surrounded by everyone; When the seventh round of shells fell, two small fuel trucks on the tarmac were also ignited.

Alexander couldn't keep up with Qin Jiandong's rhythm after the tenth round of shelling, not because it wasn't fast enough, but because it didn't have the rhythm of a completely uniform speed.

It doesn't matter if the pace of the shelling is a little chaotic, the first dozen or so shells of the mortar operated by Alexander smashed very well, and the luck was good: when Qin Jiandong was fine-tuning the mortar, a shell that flew a little farther blew up the A37 that was originally tested and was sliding away from the tarmac.

It exploded two or three meters away from the nose of the attack plane, not to mention that the front half of the fuselage was blown into tatters, and even the pilot in the cockpit became a broken sack, and a large piece of the entire nose was missing!

The attack plane's engines were still running, and it swerved towards a nearby fort, turning into a large fireball when it collided.

If there were planes in the bunker, it would quickly be ignited by the outflow, splashes of fuel.

After 15 rounds of shells, Alexander still used mortars to fire high-explosive anti-personnel shells at high speed "at will", but Qin Jiandong changed the shells here: the color of the identification band on the shell handed to him by Pavel, who matched him, was different from before, it was an anti-personnel incendiary bomb, and the ammunition body charge was added with arson, which could ignite all combustibles within a radius of 15 meters at once.

In just over 40 seconds, 30 shells were fired at the airport apron, which was enough time for people near other aircraft forts to find a place to hide, so Qin Jiandong's cannon began to adjust the shelling point under the instructions of the observation post and prevent fire everywhere.

The accuracy of the mortar is not high, but it can't stop the random smashing that falls in more than a second!

Alexander's mortar smashed the shells out with all his might to count the balls, and the fire rate of the mortar operated by Qin Jiandong was a little slow, and after three or five shells, he made a quick fine-tuning and set fire everywhere.

Not just set fire, but also a single shell down, this is still a dense shrapnel kill zone with a radius of about 20 meters.

The Colombians are fairly well-trained, and no one runs out of the house after being shelled: there are a lot of blind movies and television, shelling, and if you can't hide from people's fortifications on the side, it's better to hide in a strong enough house and don't go out.

At least for the Colombians, this is the right choice, because they have never been shelled by large-caliber heavy artillery, and their houses are not usually demolished.

As for the blind artillery everywhere, or running to the post very heroically in the face of shelling?

It's not heroic, it's a pig's head!

Scud, Iron Man?

People who want to be heroes must first think about whether they will be trapped in the range of the dense killing zone of shells, bullets do not open their eyes, and shells are even more unreasonable.

In two minutes, Alexander had finished his handiwork, and what he was holding in his hand was not a cannonball, but a Cuban-made AKM with a folding support.

Wait, wait for Qin Jiandong to quickly smash the last few high-explosive incendiary bombs on the side of the ordinary hangar of the base, where the steel frame roof was blown out of big holes!
