Smoothbore guns, as the name suggests, have no rifling in the barrel. They are much easier to process than rifled guns and have a much longer service life. Even if the bore wall has been worn away and the air tightness has deteriorated, it can still be fired normally.

.It is nothing more than the range, and the power is reduced accordingly. It can be used without pursuing long-range damage and accuracy.

In addition, the structure of this gun couldn't be simpler. It doesn't matter what wind, frost, rain, snow, desert, ocean, humidity or dryness is, and it won't be affected too much. As long as you don't make the barrel too curved, it won't break even if you think about it. It's reliable.

The performance is even higher than that of a revolver. After all, it doesn't even have a revolver and is extremely short of wearing parts.

Secondly, there are bullets. The East Asia Alliance is currently able to independently produce bullets. The artillery shells are very lucky. In other words, Hong Tao's decision was very forward-looking.

When most of the survivors around the world were still worrying about food, clothing, housing and transportation, looking at the zombies running around in panic all day long, with food, fuel and water everywhere in their sights, he had already thought of this day and immediately took action.

As much as possible the mechanical equipment and related talents from the old world have been preserved.

But no matter how it is preserved, it is impossible to continue the complete industrial chain with the population at that time, which will seriously affect the production of bullets and artillery shells, otherwise the Alliance army would not be so constrained.

But shotgun bullets are not restricted by most links in this industry chain. As long as there are enough propellants and flash caps, even if there is no copper cartridge, replacing it with a plastic or paper cartridge will still not affect normal use.

.

To put it bluntly, a shotgun is actually a small copper cannon from the 18th century. The front loading was changed to the rear loading, the separate loading of gunpowder and lead bullets was changed to pre-loading, and the use of match rope and flint for ignition was upgraded to a fire starter.

Hat, that's all.

There are no complex links such as pneumatics, ejection, and ammunition supply of modern rifles, and the requirements for bullets cannot be lower. The biggest advantage of the famous AK series is applicability and durability. But if you compare AK47 and shotguns

In comparison, it is a high-tech technology that is very troublesome to manufacture and very cumbersome to maintain.

Finally, the damage is high. Compared with shotguns, the damage of most standard weapons is relatively weak. Note that it is not the power, but the damage. For example, an automatic rifle can fire continuously, but no one can guarantee it in an emergency.

Every bullet can hit the target, so it depends on the damage of a single shot.

The shotgun is much easier in this regard. Its high-power bullets can ensure a high probability of hitting the target at medium and short ranges, such as within 50 meters or even 100 meters, without careful aiming, and the damage to unprotected targets is far greater than that of shotguns.

Ordinary bullets are high.

Of course, shotguns also have many shortcomings. For example, the continuity of firepower is insufficient, the range is even more worrying, and the recoil is much greater than ordinary firearms. However, these shortcomings are less noticeable when dealing with zombies and are easier to overcome.

The specific method of overcoming is to cooperate with each other. The army is well-trained and disciplined, and its cooperation is much stricter than that of gold diggers and cart drivers. Half a squad of soldiers search and advance in skirmish formation.

First use a long-barreled shotgun to accurately kill zombies with single-point bullets from a hundred meters away. Once they are approached, immediately draw out the short-barreled shotgun carried on your thigh and use buckshot to kill them at close range. Even if you encounter a blue devil, five people

Soldiers can also easily win by relying on two layers of firepower, both near and far.

There are too many blue devils... Come on, this is an organized army. All the nearby teams are coordinated, have plans, and have undergone long-term training. There is a high probability that they will not panic when encountering a surprise attack.

In addition, they are not alone. There are air force reconnaissance planes circling overhead, transport aircrafts watching eagerly, and infantry fighting vehicles and heavy artillery groups behind to provide fire support at any time. It is basically impossible for key targets like the Blue Devils to form a cluster.

Just after the bombardment stopped for a short while, firecrackers exploded again on the battlefield. Yes, the shotguns sounded almost like firecrackers when fired. Some were crisp and short like electric cannons, and some were dull and shocking like marlezi.

.

The effect is similar to that of small-scale live-fire exercises in daily life. The zombies that have been blown to pieces by large-caliber artillery shells hit the metal storm head-on and were immediately swept away in pieces. Even if the brain and spinal cord were not injured,

, and also lost most of his mobility.

The soldiers of the special operations regiment paid no attention to the disabled zombies who were still struggling on the ground. Some even stepped on their bodies, letting the zombies scratch and bite their boots and calves, and then were laminated on the back.

The companion used a large leather boot inlaid with steel plates to crush his skull.

“Boom, boom, boom…boom, boom…”

Suddenly, a continuous dull sound filled the battlefield. The infantry fighting vehicle, which had been silently following the skirmishers, discovered a relatively large zombie cluster and decisively fired to block it. The 30mm coaxial cannon sprayed a missile more than one meter long.

The flames swept away the zombies hundreds of meters away.

"Boom...boom..." There were two loud noises at a very short interval. A three-story building facing the street more than 300 meters away was completely shrouded in smoke.

The 100mm main gun also fired,

The commander received the notice from the reconnaissance plane and highly suspected that there was a heat source in the building. On the battlefield, the heat source represented suspected living corpses. The commander sent a high-explosive bomb without hesitation.

, as long as you catch up with a living corpse, it is worth wasting ten shells.

"Whoosh...whoosh...whoosh..." Another air force reconnaissance plane passed by at a low altitude, leaving three flares behind its butt.

"Everyone find cover on the spot, be careful to stay away from high-rise buildings, and the bombardment will begin in 3 minutes!"

Seeing the burning flare in the air, an infantry fighting vehicle stopped suddenly, the top cover was lifted, and an officer with the rank of major came out and gave the order to the high-power military walkie-talkie. He repeated it over and over again until

There were bursts of sharp roars in the sky above his head, and he retracted his body into the infantry fighting vehicle.

The earth is shaking, the fire is raging, and all places hit by 122-caliber high-explosive bombs have fallen into boundless hell. No matter lying down, sitting, lying, squatting or standing, you can't escape the lash of iron and fire.

.

Three minutes later, the bombardment suddenly stopped. The special operations regiment half a kilometer away immediately came to life again. They crawled out of the bunkers and bomb craters one after another, shook the dust off their bodies, and continued to advance southward at their accustomed speed.

The infantry fighting vehicle that was following behind also spewed black smoke and ran to the forefront. Before the smoke and dust completely dissipated and the reconnaissance plane was unable to provide details for the time being, a protective wall was pulled up for the infantry. All creatures trying to get close would be

Be greeted by large-caliber machine guns and high-explosive bombs.

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

First, heavy firepower opens the way, and then the armored troops cover the infantry advance. If the zombie group charges, that's great. The reconnaissance opportunity above the head will quickly notify the shooting elements to the heavy artillery behind, and the shells will drill into the zombie group like they have eyes.

Maximize the lethality.

If the zombie swarm does not charge or is not dense enough, the heavy artillery will not speak. The special operations group will only target the zombie swarm and not enter the building. The rest of the cleanup work will be left to the ordinary troops who follow up.

At this time, the problem is thrown to the living zombie. If it doesn't come out to expand its control range, it can only watch the zombie group being eaten away bit by bit. If it can't help but come out, I'm sorry, the thermal imaging equipment on the reconnaissance plane is waiting.

At this moment.

In less than a minute, the area where the living corpses appear will be covered by long-range large-caliber incendiary bombs. The transport planes that have been hovering over the battlefield will also rush over at the fastest speed, using more powerful aviation incendiary bombs to focus on finishing the damage.

.As long as the living corpse will not be involved in permanent official affairs, the only fate waiting for it is to be burned to ashes.

Therefore, the new tactics created by Zhang Ke may seem clumsy, but in fact they are very effective against living zombies whose IQs cannot keep up with humans, and they are very flexible in fighting and escaping. The speed of zombies cannot catch up, and the blue devil will die if it catches up, and it will not cause too much damage.

Big damage.

But there is a problem that humans have not yet found a way to overcome, and that is the influence of weather. During the day, with sufficient vision, the human army can discover the direction of the zombie swarms and make predictions in advance to avoid being surrounded.
