When Gao Yang and Brian parted, it was about 9 am, and when Gao Yang's plane set off, it was around 5 pm.

From the perspective of time, Gao Yang felt that he should be able to arrive in Odessa at about the same time as Brian, but there is a prerequisite, that is, Brian had to drive to Odessa.

The roads in Ukraine are not very bad, they are definitely much better than those in Africa. There are highways from Kiev to Odessa, but this highway has not received decent maintenance and repair work in at least ten years.

It is about 700 kilometers from Kiev to Odessa. With the bad road conditions, Gao Yang felt that he might have arrived in Odessa earlier than Brian, and arrived at the place where Yarebin was talking nonsense earlier.

But it was still good when we left Kiev, but when we arrived at the airspace not far from Odessa, the weather became worse. When Gao Yang was waiting for him to come out of the airport and drove to the place Yarebin said, the rain had already started to fall.

There are still dozens of kilometers from the airport to the cape mentioned by Yarepin. After departure, the rain quickly became heavier until it reached the level of heavy rain.

It was already dark and the rain was so heavy that the wiper was not too late to discharge the water from the front windshield when it was turned on to the maximum gear, which caused the sight to be blurred. Walking on roads with very incomplete infrastructure, you could not even see the sign line in the middle of the road.

Rebrov was driving, and the speed was very slow. He sat up straight and stared at the road ahead, but he still couldn't get up. Gao Yang sat in the passenger seat, looking thoughtful.

Rebrov finally couldn't help but whisper: "Sir, the rain is too heavy, it's very dangerous to rush on the road like this. Should we stop first and wait for the rain to get a little lighter before leaving?"

Gao Yang raised his head, looked at the situation outside, and whispered: "It's nothing, keep walking. If you feel dangerous, walk slowly."

"But sir..."

Gao Yang looked at Rebrov and said gently: "If I haven't issued a clear order, you can ask me, and after I have issued a clear order, you will execute it. Do you know?"

"Yes, sir."

Gao Yang lowered his head again and whispered: "Rebrov, ask you a question. Point A is thirty kilometers in a straight line distance between point B. The cannon is arranged at point A and point B is the target. What should I do if I want to use cannons to bomb point B?"

Rebrov said without hesitation: "This question is too broad. First of all, you have to know the subjective side viewing coordinates and elevations of the artillery command post or artillery position. Then send the artillery scout to detect the target, determine the coordinates and elevations of the target, and then wait for the scout to use the coordinate data of the target, the artillery command post calculates the shooting elements. The position can be fired. After the artillery scout is corrected and the shooting effect is evaluated, the next step is to continue shelling or change the coordinates."

Gao Yang nodded, then whispered: "What if there are no scouts? Can the use of drones to detect ranges replace the role of scouts?"

Rebrov looked embarrassed and said loudly: "In some cases, it can, and in some cases, we cannot. Use drones to observe the targets and fire immediately after receiving data. These must be those advanced ones. Drones must be the same as guns. Advanced artillery with fire control and ballistic calculations are easy to use. If it is an old gun, people need to calculate the shooting elements. It is really not as convenient as using a scout."

Gao Yang sighed slightly and said, "That's it. If you give you a D30 artillery regiment and two drones to reconnaissance, can you carry out an accurate shelling?"

Rebrov thought for a moment and nodded, "It's OK. But this method has great disadvantages. It must be corrected after multiple test shots to accurately hit the target, so it is more suitable to deal with fixed targets. It is more difficult to kill and have vitality. There is also a drone that can be large enough. Even if a small drone can fly so far, can the control signal be that far? Also, drones must be specialized gun reconnaissance drones, but ordinary drones cannot."

Gao Yang shook his head and shouted: "I can get a special artillery reconnaissance drone, but I don't seem to have a fixed target to blow up. Forget it, it's better to be realistic. I'll give you two artillery groups. You must be able to provide me with extremely accurate artillery fire support at any time. Can you do it?"

Rebrov said without hesitation: "Two gun groups? Of course, it can, what's the difficulty?"

Gao Yang coughed lightly and said loudly: "So, what if all the people in these two artillery groups are illiterate? Well, the best math level can reach the level of third grade in Ukrainian primary school. I think it should be possible. Forget it, to be safe, it should be based on the level of first grade in primary school. You can add, subtract, no multiplication or division, and equip, add, subtraction within 100 numbers."

Rebrov said in extreme surprise: "All illiterate? The best one can be at the first grade level of elementary school? How to fight?"

Gao Yang sighed and said helplessly: "That's not the case. Then, if you find some helpers for you, you think at least many people can support two artillery groups."

Rebrov thought for a moment, then said in embarrassment: "If, if, if, if, the two gun groups you mentioned have the most basic ability, I will shoot the elements and coordinates for them, and they can control the cannons correctly, maybe, I can also make them run normally, but the speed will definitely be much slower."

Gao Yang suddenly felt energetic and shouted: "Oh, can it work? Very good, tell me how you do it."

Rebrov shouted: "Simple, I just do everything myself. I will set the coordinates of the position first, then serve as a scout myself. After obtaining the coordinates of the target, I will calculate the shooting elements by myself, and then pass all the data back. Then, let the illiterate gunners be responsible for loading and firing the cannons."

Gao Yang exhaled and whispered: "Very good, very good. This condition should still be achieved. After training for so long, you won't be able to master these things."

Rebrov said carefully: "There is another thing I want to say, I am very familiar with the d30 cannon. If it can't be so far away, it can be more than ten kilometers at most. If the distance is close, it will be easier."

Gao Yang smiled and said loudly: "Yes, d30 is not possible, but the 2A65 type 152mm cannon is enough. I have 36 152 cannons on my hand, which has never been useful. Now, I will give you a heavy artillery regiment first. If you really can, I will give you a few more artillery regiments."

Rebrov widened his eyes and said in surprise: "Take me a heavy artillery regiment? Or do I do all the technical work myself? Are you serious?" (To be continued.)
