Chapter 1887 (1/2)

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

”How far is it?”

Leibrov listened attentively, stretched out his hand to Gao Yang and waved to him to stop talking. After a moment, leibrov said nervously: ”the impact point of the shell is very close to us, no more than three kilometers. This is the sound of 122 mm shell.”

After listening again for a moment, leibrov suddenly said, ”152! This is 152 cannon!”

Gao Yang didn't dare to speak for fear of interfering with leibrov. At this time, a dense explosion sounded continuously, as if it was a sound. When the explosion passed, leibrov immediately said, ”122 mm rockets, volley! Otherwise, we can't reach this density.”

After listening attentively for a moment, leibrov nodded to Gao Gao and said, ”nothing else. The firing distance of these three guns is ten kilometers away, but it won't be too far. We can still hear the faint sound of firing. Listen! Do you hear? It's a stuffy sound. This is the sound of 152 artillery. There aren't many large caliber guns in the main army. There should be only three.”

Gao Yang swallowed his saliva and said, ”such a God? How can you hear it?”

Leibrov smiled: ”it's very simple. You can always hear the sound of 152 shell explosion. At most, there are only three explosions at the same time, and then continuous shooting. It's the normal speed of three cannons when firing rapidly, which is easy to distinguish.”

Gao Yang stretched out his thumb and said anxiously, ”what about the 122 gun?”

”I can't tell how many, about ten, almost. As for rockets, it's about six. From this configuration and the number of guns, what is launching artillery is a mixed artillery battalion, nine 122 guns, three 152 cannons and six 122 rockets. There should be no mistake in having such a temporary mixed battalion in Ukrainian Artillery Force.”

Gao Yang said sincerely, ”Qiang! I didn't expect you to hear this. I can only tell what guns are. I can't tell the distance, and it's even more impossible to tell the number of guns.”

Leibrov wiped his nose, listened to the gunfire and said, ”this is the plain. It's easier to distinguish these in the plain. If it's a mountainous area or the buildings are particularly tall, it won't work. First, the sound can't spread so far, and then there is interference such as echo, it won't work.”

After that, leibrov suddenly looked at Gao Yang and said loudly, ”there's trouble. This is artillery preparation.”

Gao Yang certainly knows what artillery preparation is. Before launching an attack, he first focuses on using artillery to bomb the enemy and carry out organized, planned and targeted artillery attacks. This is artillery preparation. Since it is preparation, the end of preparation is naturally an attack.

”Are you sure it's artillery preparation?”

Leibrov said with great confidence: ”of course, the artillery density and firing speed are the textbook artillery preparation. That's what I learned. I can't hear it wrong. It can't be regarded as large-scale artillery preparation, but it must be artillery preparation. This will soon prove that after the artillery preparation is over, it should be extended shooting.”

Gao Yang immediately said, ”according to your tutorial, how long is the artillery preparation?”
