"Ahmed, what's going on?" Looking at the red dots on the map, which were gradually advancing, and it was already very close to the city wall, Li Lan couldn't help but pick up the radio walkie-talkie and ask Ahmed, who was on the battlefield.

"Sir, the enemy has armored vehicles today, our fire has been neutralized a lot, and now the enemy has attacked to a point of only fifty or sixty meters from the city walls. But rest assured, Commander, we will hold the walls and never let the enemy get closer. On the radio, the sound of gunfire was clearly audible, but Ahmed's answer was louder.

"Very good, good morale. There were not many wounded soldiers. ”

"There are quite a few, but as long as there are soldiers who cannot continue fighting, I have already arranged for them to go to the rear." Ahmed said.

"Hmmm! Stay safe. Half an hour later, let the rest haode troops take over the defense, and you will take this opportunity to rest. ”

"Humble duty understands."

After ending the call with Ahmed and looking at the red dot on the south side of the map, Li Lan's heart became heavier and heavier.

The situation on the battlefield today is not optimistic, the enemy armored vehicles have come out, and it seems that those shili are fighting for the old book. Moreover, the enemy's forces have been replenished all the time, and the strength outside the base has not been reduced much.

And the Bossaso government army has not moved, which is what Li Lan is most worried about. Although the local shili are united and their strength is not weak, they cannot be compared with the government army. Even if Bossaso's government army is not very good, it is not something that Li Lan can completely contend with now.

In front of him was a group of many shili who were like wolves and tigers, eyeing the base, and behind them were also government troops who were also salivating over the base.

Now all he can do is work hard and try his best to keep the base, otherwise let alone the mission, even his own life will not be guaranteed.

Looking at the enemy's offensive concentrated on the southern city wall, Li Lan kept thinking in his heart.

He is not very worried about the enemy who is currently concentrated outside, what he is most worried about is the government army, once he and these shili are defeated, the government army will definitely take advantage of the fire to loot, and he will be powerless to resist the government army at that time.

The current situation must be changed and the situation deliberately created by the Government forces must be broken.

And before government forces can intervene, a stronger defensive landscape must be re-established.

After identifying these two core issues, Li Lan once again set his sights on the map.

There are not many powerful weapons in the base at present, and the weapons that can cause damage to armored vehicles, except for RPGs, are sentry guns. However, it is now impossible to build a sentry cannon on the battlefield, and as soon as the sentry cannon comes out, it will become the key target of the opponent's rocket artillery, as long as a few RPG rockets hit in a row, relying on the maintenance speed of the base, it is impossible to keep these defensive weapons.

Even a highly defended machine-gun bunker can't survive in such an environment for long. Now, except for a few defensive weapons in front of the north and west walls, the defensive weapons in the other two directions have all been eliminated.

In the face of more well-equipped government forces, without weapons such as sentry guns, the defense of the base will be greatly reduced. Even if you don't pay for a mass-produced RPG, you can't make up for the lack of defense at the moment.

A sentry cannon that can cover most of the battlefield is definitely much more powerful than the individual weapons that mobilized soldiers have now.

Li Lan also thought about building another city wall behind the outermost city wall, and then put the sentry cannon and machine gun bunker between the two city walls, and after the first city wall was lost, he used a large amount of explosives to blow up the outermost city wall, revealing the prepared haode sentry cannon and machine gun bunker, and giving the enemy an instant and powerful blow.

But on second thought, this is definitely not the best solution, because these sentry guns and machine gun bunkers can be used for too short a time, and the powerful firepower can cause great damage to the enemy, but it will also quickly be eliminated by mortar and bazooka.

This is just a drop in the bucket, and it will waste a lot of base funds. A sentry cannon is 5,000 base funds, and a machine gun bunker is 1,000 base funds more expensive than a sentry gun.

How to bring out the firepower of these two defensive units and how to make them stronger on the battlefield has become Li Lan's biggest headache now.

According to the battlefield situation these days, these defensive units are all taken out with bazookas when the enemy is lurking to about 400 meters. Because whether it is the opposite side or the mobilized soldiers, they are using the most common RPG-7 in the RPG family, this forty-millimeter bazooka, although its effective range is 800 meters, but only to 400 meters, is the best range, and it is at such a distance that there is accuracy at all.

On the other hand, although the range of the sentry artillery and machine gun pillboxes is two or three kilometers away, the firepower is not very dense, the battlefield is very empty, the enemy is extremely scattered, and the ground is uneven, as long as the opponent avoids the crossfire point, under the cover of mortars, it can still approach 400 meters.

If these two defensive weapons are not to be eliminated quickly, these unfavorable factors must be changed.

After thinking about it for a long time, Li Lan also came up with the measure of re-establishing the defense line. But the effect is not much better than it is now, and it cannot change the battlefield situation very effectively.

At this time, Li Lan accidentally saw the four-meter-thick city wall, and couldn't help asking, "Assistant, can the construction unit be built on the city wall?" ”

The original thickness of the wall was two meters, but because it was a peripheral wall, Li Lan put the second wall and the first wall together very early, and it became the city wall with a thickness of four meters. Otherwise, relying on the two-meter-thick city wall, it would have collapsed long ago under the blows of bazookas and mortars. Even the gate that was originally left behind was blocked by a large number of sandbags.

"As long as it's flat and it's in a fixed location, enough to accommodate a unit-sized open space, it can be built."

Hearing the assistant's answer, Li Lan was immediately overjoyed, the area of the sentry cannon and machine gun bunker is not very large, the width of four meters is enough, and when the time comes, as long as a small section of the city wall is built and the width of the city wall is widened, the soldiers can also walk on it smoothly.

And once the sentry cannon is on the wall, the battlements and sandbags become another shield for it, and while still unable to defend against projectile mortar shells, they can greatly reduce the threat of bazookas. When the time comes, with the firepower on the city wall and its cooperation, the firepower density of the base's defense will increase a lot.

Since it can be built on the city wall, Li Lan needs to make a good calculation.

At present, the fighting is concentrated in the south, and it is inevitable that the city walls at this time are also full of potholes, full of craters of different sizes, the smallest is only a few centimeters in diameter, and the largest is a diameter of one or two meters, and the depth is nearly one meter.

This six-kilometer-long city wall has become the main direction of the enemy's concentrated firepower. If it weren't for the defense of the city wall, the thickness had reached four meters, and the opponent did not have large-caliber siege artillery, this wall would have collapsed under artillery fire.

With a length of six kilometers, it is impossible to have a sentry cannon every few tens of meters, after all, the cost of up to 5,000 is not something that Li Lan can squander at will.

But in order to exert firepower, it can't be built too little.

Each sentry cannon was built for two hours, and although it was arranged to deal with the real enemy, the government forces, it was not possible to wait for the main master to arrive. It is necessary to build a little bit in advance, and then wait for the main master to come, and then slowly improve it.

In addition, since it is located on top of the city walls, it cannot exert the lethality of flat fire, so the need for crossfire becomes very important.

Li Lan had never attended a military academy and did not know how to calculate the most reasonable firepower deployment, but he did not know it, which did not mean that others did not know.

"Ahmet, I would like to place machine-gun bunkers and sentry guns on the city walls, how far apart do you think is appropriate?" Li Lan is not a procrastinator, and when he thought of this, he immediately contacted Ahmed.

"Commander, an interval of two hundred to three hundred meters is fine." On the radio, the phone was still the same, and Ahmed continued to be accompanied by violent gasps as he answered, obviously very tired.

"Got it!" Ending the intermittent conversation with Ahmed, Li Lan looked at the pitiful three-digit figure above the monitor.

The solution is to think of it, and suffer from shyness in the pocket. However, Li Lan is not in a hurry, he believes that it will take a long time before the government army officially intervenes, and he will have the time and funds to arrange new defense affairs.

And now he needs to go and establish a dialogue with the major shili leaders outside.
