Smoothbore guns, as the name suggests, have no rifling in the barrel, and are relatively much easier to process than rifled guns, and have a much longer service life. Even if the wall of the chamber has been worn out and the air tightness has deteriorated, it can still be fired normally. It's nothing more than a reduction in range and power, and it can be used without long-range killing and accuracy.

In addition, the structure of this gun is also simple, what wind, frost, rain, snow, desert, ocean, humid and dry, I don't care at all, and it will not be affected too much, as long as you don't make the barrel too bent, you can't break it if you want to, and the reliability is higher than that of a revolver. After all, it doesn't even have a runner and is desperately short of wearing parts.

The second is bullets, and the East Asian Alliance is very fortunate to be able to independently produce bullets and artillery shells, or Hong Tao's decision was very forward-looking.

When most of the survivors in the world were still worried about food, clothing, shelter and transportation, and watched the zombies running rampant all over the place, full of food, fuel and water, he had already thought of this day, and immediately took action to save as many machinery and related talents as possible from the old world.

But no matter how it is preserved, it is unlikely that the entire industrial chain will be continued with the population of that year, which seriously affects the production of bullets and shells, otherwise the Union army would not be so constrained.

However, the bullets of the shotgun are not limited by most links in this industrial chain, as long as there is enough propellant and fire cap, even if there is no copper cartridge, it will not affect the normal use of plastic or paper cartridges.

To put it bluntly, the shotgun is actually a small bronze cannon in the eighteenth century, which has changed the front loading to the rear loading, changed the separate loading of gunpowder and lead bullets to a pre-fixed installation, upgraded the ignition with fire rope and flint to a fire cap, and that's it.

There are no complex links such as pneumatics, shelling, and ammunition supply of modern rifles, and the requirements for bullets cannot be lower. The biggest advantage of the well-known AK series is applicability and durability. But if you compare AK47 with shotguns, it belongs to the high-tech that is very troublesome to manufacture and very cumbersome to maintain.

Finally, the damage is high, and most standard weapons have relatively weak damage compared to shotguns. Note that it's not power, it's damage. For example, an automatic rifle can fire continuously, but no one can guarantee that every bullet will hit the target in an emergency, so it depends on the damage of a single shot.

The shotgun is much easier in this regard, its high-powered bullets can ensure a high probability of hitting the target at medium and close ranges, such as 50 meters or even 100 meters, without careful aiming, and the damage to unprotected targets is much higher than that of ordinary bullets.

Of course, shotguns also have many disadvantages, such as insufficient fire continuity, even more worrying range, and much greater recoil than ordinary firearms. However, these shortcomings are less conspicuous when dealing with zombies, and they are relatively easy to overcome.

The specific way to overcome it is to cooperate with each other, the army is trained and disciplined, and it is much more rigorous than the gold diggers and coachmen in terms of coordination, and half a squad of soldiers searches and advances in a straggler formation.

First, use a long-barreled shotgun to accurately shoot zombies with a single-headed bullet from a distance of 100 meters, and once you get close, immediately pull out the short-barreled shotgun carried on your thigh and kill with a deer bullet area at close range. Even if they encounter the Blue Devil, five soldiers can easily win by relying on two layers of firepower, near and far.

There are more blue devils...... Please, this is a formed army, and all the squads in the vicinity are cooperative, planned, and trained for a long time, so there is a high probability that they will not panic in the event of a surprise attack.

In addition, they are not alone, there are air force reconnaissance planes hovering overhead, transport planes are eyeing overhead, and there are infantry combat vehicles and heavy artillery groups in the rear to provide fire support at any time, and it is basically impossible for key targets such as the Blue Devil to form a cluster.

The shelling had just stopped for a short time when firecrackers rang out again on the battlefield. That's right, shotguns sound like firecrackers when fired, some are crisp and short like electric cannons, and some are dull and shocking like thunder.

The effect is similar to that of small-scale live-fire exercises on weekdays, and the zombie hordes that have been blown up by large-caliber shells hit this metal storm head-on, and they were immediately swept down in pieces. Even if it didn't hurt the brain and spinal cord, he lost most of his mobility.

The soldiers of the special operations regiment did not pay attention to the disabled zombies who were still struggling on the ground, and some even stepped directly on their bodies, allowing the zombies to scratch and bite on their boots and calves, and then the skulls were crushed by their companions on the back with large scalp boots inlaid with steel plates.

"......Tom tom Tom ......"

Suddenly, a coherent and dull sound filled the battlefield, and the infantry chariot, which had been silently following the stragglers, found a relatively large group of zombies and decisively shot at the block. The 30mm coaxial cannon spewed out flames more than a meter long, sweeping away the zombie hordes hundreds of meters away.

"Boom...... Boom ......" were two loud noises at short intervals, and a three-story building facing the street more than 300 meters away was completely shrouded in smoke on a 97-step chariot

The 100-mm gun also fired,

The commander was informed by the reconnaissance plane and highly suspected that there was a heat source in the building. On the battlefield, the heat source represents a suspected living corpse, and the commander does not hesitate to send a high-explosive bomb. There are jujubes and no jujubes to hit three poles, as long as you catch up with a living corpse, it is worth wasting ten shells.

"Whoosh...... Sou...... Whoosh...... "Another Air Force reconnaissance plane skimmed from a low altitude, leaving three flares behind the butt.

"All find shelter in place, pay attention to stay away from high-rise buildings, and shell in 3 minutes!"

Seeing the scorching flare burning in the air, an infantry chariot came to an abrupt halt, the roof was lifted, and an officer wearing the rank of major came out, giving orders to the high-powered military walkie-talkie. It was repeated over and over again, until a sharp whistling came from the sky overhead, and then he shrank into the chariot. Eight Chinese Net

The earth is trembling, the fire is raging, and all the places hit by 122 caliber high-explosive shells have fallen into a boundless hell, whether they are lying on their stomachs, sitting, lying, squatting or standing, they cannot escape the whipping of iron and fire.

Three minutes later, the shelling suddenly stopped, and the special operations regiment, half a kilometer away, immediately came to life again, crawled out of bunkers and craters one after another, shook off the dust on their bodies, and continued to advance south at a customary pace.

The infantry chariot that followed closely behind also spewed black smoke and ran to the forefront, pulling up a protective wall for the infantry when the smoke and dust had not completely cleared and the reconnaissance aircraft could not provide details for the time being. All creatures that try to approach will be greeted by large-caliber cannons and high-explosive shells.

This is the result of the training of the Special Operations Regiment of the 1st Brigade of the Reserve Force for half a year, the links are very simple, and there are few technical actions and precautions, as long as the officers are not confused, it is difficult to make mistakes.

First heavy fire cleared the way, then the armored forces covered the infantry advance. If the zombie group charges, it would be great, the reconnaissance machine above the head will quickly notify the heavy artillery behind the shooting Zhu Yuan, and the cannonballs will drill into the corpse group like eyes, and the lethality will be maximized.

If the zombie group does not charge or the density is not enough, the heavy artillery will not speak, and the special operations regiment will only target the zombie group and not enter the building, and the rest of the cleanup will be handed over to the ordinary troops who follow behind.

At this time, the problem is thrown to the living corpse, and if it does not come out to expand the range of control, it can only watch the zombie group be eaten up little by little. If it can't help but come out, I'm sorry, the thermal imaging equipment on the reconnaissance plane is waiting for this moment.

In less than a minute, the area where the living corpses appear will be remotely covered by large-caliber incendiary shells. Transport planes that have been hovering over the battlefield will also pounce as fast as they can, and use more powerful aviation incendiary bombs to make up for the knife. But any living corpse will not drill into permanent business, and only the fate that awaits it will be burned to ashes.

Therefore, the new tactics created by Zhang Ke seem to be very clumsy, but in fact, they are very effective in dealing with living corpses whose IQ cannot catch up with humans, and they are very flexible in fighting and escaping. The speed of the zombie can't catch up, and the blue devil can't catch up with it, and it will be sent to death, so it won't cause much damage.

But there is one problem that mankind has not yet found a way to overcome, and that is the influence of the weather. During the day, with sufficient vision, the human army can discover the direction of the zombie herd's movement and make predictions in advance to avoid being surrounded.

At night, there is no vision, the large army has become a burden, no matter how many great results have been achieved, they have to obediently retreat to a relatively empty and safe area, and the progress during the day is equivalent to killing and injuring a large number of zombies.

"Brother Shen!"

"Hmm!"

Shen Changqing walked on the road, and when he met someone he knew well, he would say hello to each other or nod his head.

But it doesn't matter who it is.

There was no superfluous expression on everyone's face, as if they were very indifferent to everything.

on this.

Shen Changqing is used to it.

Because this is the Demon Suppression Division, it is an institution that maintains the stability of Great Qin, and its main responsibility is to kill demons and monsters, and of course there are some other side jobs.

Arguably.

In the Demon Suppression Division, everyone has a lot of blood on their hands.

When a person is accustomed to seeing life and death, then he will become indifferent to many things.

When he first came to this world, Shen Changqing was a little uncomfortable, but over time he got used to it.

The Demon Suppression Division is huge.

The people who can stay in the Demon Suppression Division are all powerful masters, or people who have the potential to become masters.

Shen Changqing belongs to the latter.

Among them, the Demon Suppression Division is divided into two professions, one is the town guard and the other is the demon exterminator.

Anyone who enters the Demon Suppression Division starts with the lowest level of demon slayer.

Then step by step, he is expected to become a town guard.

Shen Changqing's predecessor was a trainee demon slayer in the Demon Suppression Division, and he was also the lowest level of the demon slayer envoys.

Have memories of the predecessor.

He is also very familiar with the environment of the Demon Suppression Division.

It didn't take long for Shen Changqing to stop in front of an attic.

Unlike other places full of slaughter, the attic here seems to stand out from the crowd, and in the bloody Demon Suppression Division, it presents a different tranquility.

At this time, the attic door is open, and there are occasional people entering and exiting.

Shen Changqing only hesitated for a moment, and then stepped in.

Access to the attic.

The environment has changed in vain.

A burst of ink fragrance mixed with the faint smell of blood came to his face, making his brow furrow instinctively, but quickly stretched.

The smell of blood on everyone's body in the Demon Suppression Division is almost impossible to clean.
