Gao Yang and Rebrov came outside the house and listened to the sound of the cannon.

“How far is it?”

Rebrov listened in a slanted ear, stretched out his hand to Gao Yang and waved it, indicating that he should not speak. After a while, Rebrov said nervously: "The landing point of the shell is very close to us, not more than three kilometers. This is the sound of a 122mm shell."

After listening for a while again, Rebrov suddenly said, "152! This is the 152 cannon!"

Gao Yang did not dare to speak, for fear of disturbing Rebrov. At this time, a dense explosion sounded suddenly, as if it was a sound. When the explosion sounded over, Rebrov immediately said: "122mm rocket launcher, volley! Otherwise, it would not reach this density."

After listening intently for a while, Rebrov nodded to Gao Yang and said, "There is nothing else. These three types of cannons are ten kilometers away, but not too far. We can still hear the faint sound of cannons. Listen! Did you hear it? A very dull sound, this is the sound of the 152 cannons fired. There are not many large-caliber cannons in the main palace army, so there should be only three."

Gao Yang swallowed and said, "So amazing? How did you hear it?"

Rebrov smiled and said, "It's very simple. You can always hear the sound of the explosion of the 152 shell. At most, only three explosions occur at the same time. Then the continuous shooting is the normal speed of the three cannons when they fire rapidly, which is easy to distinguish."

Gao Yang stretched out his thumb and said anxiously: "Where is the 122 cannon?"

"I can't tell how many, about ten, almost the same. As for rocket launchers, there are about six. Judging from the configuration and number of artillery, the ones that are launching artillery are a mixed artillery battalion, with nine 122 guns, three 152 guns, and six 122 rocket launchers. If there is such a temporary mixed artillery battalion in the Ukrainian artillery unit, it should be impossible to make a mistake."

Gao Yang said sincerely: "Strong! I didn't expect you to hear these things. I can only tell you what kind of cannons it is. The distance is not obvious, and it is even more impossible to hear the number of cannons."

Rebrov wiped his nose and listened to the sound of cannons while listening to the sound of cannons: "This is a plain. It is easier to distinguish these in the plains. If it is a mountainous area or the buildings are particularly tall, it will not work. First of all, the sound cannot be transmitted so far, and there will be interference such as echoes, which will not work."

After saying that, Rebrov suddenly looked at Gao Yang and shouted: "I'm in trouble, this is the preparation for artillery fire."

Of course, Gao Yang knew what artillery preparation was. Before launching an attack, he would use cannons in a concentrated manner, explode the enemy, and carry out organized, planned and targeted artillery strikes. This is artillery preparation. Since it is preparation, then the preparation is to end it naturally launch an attack.

"Are you sure it's fire preparation?"

Rebrov said confidently: "Of course, the density of artillery fire and the firing speed are just the artillery fire preparations in textbooks. I learned this. I can't hear it wrong. This cannot be considered a large-scale artillery fire preparation, but it must be artillery fire preparations. This will soon prove that the artillery fire preparations are over and the next step is to extend the fire."

Gao Yang immediately said: "According to your tutorial, how long will it take to prepare for artillery fire?"

"There is no fixed time limit, but it must be achieved with a certain degree of artillery density and intensity before the artillery preparation can be considered to be completed. Well, the opponent's artillery has observers, and they will make judgments based on the damage effect. Now is the stage of intensive artillery bombing. The artillery preparation has just begun. I guess at least a few more minutes to destroy the militia's defense line and conduct extended shooting. The tanks and infantry of the Zhengfu Army should charge."

Gao Yang said a little nervously: "The official army has occupied the highway and is already on the edge of the city. If the artillery fire extends, Butan will charge together, so you have to fight into the city, that is street fighting!"

Rebrov looked at Gao Yang and shouted, "Boss."

"Um?"

"We are on the edge of the city, and we are in the northwest corner. The government's artillery extension and the Bundan coordinated charge are not necessarily flying to the city. They may be going to complete the encirclement of Khartssk."

This small-scale special operations background is different from the officers trained in large-scale operations of the regular army. He has specialized in his profession and fixed thinking. Gao Yang and Rebrov think differently.

Gao Yang was thinking about how to attack Huanglong and complete a beheading battle to destroy the enemy's command center. So when he put himself in the combat mode of the official army, he always thought about how to completely occupy the city since the artillery fire was ready.

As for Rebrov, he was not thinking about taking Karzisk in one fell swoop. He was thinking about how to use artillery fire to clear the defense line outside the city, and then how to encircle the city with tanks and infantry. As long as Karzisk is surrounded, the militia loses a fixed firepower point and a heavy weapon to deal with tanks, Karzisk can stay still. If there are enough reinforcements, there will be a large street battle. If there are not enough troops, then the cutting of Karzisk is completed. As long as Karzisk is surrounded, the tactical purpose has been completed.

When Rebrov said this, Gao Yang's cold sweat suddenly came down, and then he immediately shouted on the intercom: "Panda! You two are back quickly, and tell the people of Dolescent to evacuate quickly! The wounded must be transferred immediately! The enemy is about to launch a cannon attack, and the answer is over!"

"The panda was received. The wounded soldiers had been transferred and the bodies had been buried. We have been relocating the wounded soldiers immediately after the rescue was completed. Now there are only a dozen minor wounded soldiers, and the notice has been completed."

Gao Yang exhaled, then said anxiously: "No matter what you are doing, put it down immediately and go back into the basement. After the enemy's artillery fire is ready, it is likely to launch an attack. We are likely to be the target here and we can't wait any longer."

"I understand, but this place has become a field hospital at present. I can't tell the person in charge here. He refuses to evacuate. He insists on receiving the evacuation order before leaving."

"Fake! Is he wrong? This is a war, why are there such a rigid guy?"

"Yes, he is too responsible. He insists on keeping his post. As long as there are wounded soldiers who may be sent to him, he cannot leave."

Neat could not have known everything that was happening on the front line, and the commander of Khaltzsk might not have realized the opponent's plan, or had not yet taken care of the field hospital.
