When I was learning about coordinate observation, I always had a question in my mind...... When the Second Company was fighting on the front line in the past, Marx and his party used the method of "test firing", but the accurate measurement we have learned now does not seem to require test firing at all, as long as the distance and elevation are calculated accurately, it will not be wrong to cover a large area of artillery.

When I asked the battalion commander, I learned that there are times when it is impossible to measure accurately on the battlefield, such as when the fog is heavy and the rain is heavy...... At this time, the visibility is only a few tens of meters, and the steering wheel cannot be seen through, so there is no way to aim at the target, and there is no way to measure the angle and calculate the distance if there is no aim. Another example is when there is no known location around...... The specific coordinates determined by the observer are all determined on the basis of the known azimuth objects, such as towers, mountain peaks, and high ground with known coordinates, plus the distance between the azimuth object and the target.

At this time, it is necessary to use visual inspection......

The so-called visual inspection method is to poke a point on the map according to the ability and experience of map reading, measure the coordinates and elevation (there is a circle of Gaussian contour lines on the military map, and the contour lines are used to represent the elevation), and then try to make a few shots and slowly adjust, just like Marx did before.

Of course, this method is also used in times of emergency, such as when a large number of enemy cars and tanks are suddenly found in the field...... Because the speed of the cars and tanks was relatively high, there was no hurry to measure the coordinates at all, and by the time the coordinates were measured, the enemy's cars and tanks had already driven away.

Therefore, the advantage of this method is that it is fast, and the disadvantage is that the error is large, and if it is not accurate, it will also warn the enemy...... For example, a test shot shot went far. The second shot was corrected and it was not possible. At this time, the enemy already knew that he was being targeted by the opposing artillery observers. A reaction will be made soon.

The warriors couldn't help but wail when they knew that there was another way......

"Battalion commander!" Liang Lianbing shouted: "If there is this method, we will say it earlier, we don't need to calculate the coordinates so hard, right?" ”

Battalion Commander Wu answered this question for me: "Do you think the artillery shells are fired casually? Every time the artillery fires, they have to risk their lives being suppressed by the enemy's artillery! So if you don't have precise coordinates or an emergency, you don't need to look at it visually! ”

"That's it!" I chimed in beside me: "You think the cannon is pretending to be a family...... You can fight as much as you want? ”

"What's more!" Battalion Commander Wu added: "If you haven't learned to calculate coordinates, then how can you poke points on the map?" Even if you hit the point, how do you correct the offset? If you poke an old street, you will be pointed to Hanoi! ”

The soldier laughed out loud, and Xu Guochun joked on the side: "That feeling is good, and it will hit Hanoi directly!" ”

I ignored the foolish coaxing of the fighters and asked again: "How can the enemy artillery find the target and suppress my artillery?" ”

"The method is the same!" Battalion Commander Wu replied: "Both the enemy and us have set up artillery observation posts on the high ground, and when the other side fires artillery, there will inevitably be fire and smoke. Especially at night, it can be seen more clearly, as long as the two heights are connected and aim at the fire and smoke with the steering wheel, the coordinates and elevation can be calculated quickly! ”

"Oh!" When I heard this, it dawned on me that it was no wonder that the artillerymen often had to fire a few shots before leaving. Otherwise, it is necessary to prepare some more artillery fire to counter-suppress the enemy's artillery.

Later I learned that there was more to the artillery contest than that...... Because artillery observation posts are like the eyes of the enemy's long-range artillery fire, both sides often have to send scouts to eliminate the enemy's artillery observation posts before a large-scale attack or artillery battle.

Of course, the artillery observers on both sides will also be on guard, so this is another bloody battle between you and us...... It is no wonder that the warfare of this era cares so much about occupying the commanding heights, as the saying goes, if you stand high, you can see far, and mastering the commanding heights means that long-range artillery fire can hit the enemy's hinterland farther and more accurately.

However, all this was overturned with the introduction of artillery sighting radar by our army...... At this time, we are in a honeymoon phase with the Yankees. Therefore, the Yankees were happy to pull the strings so that our army successfully purchased two gun-sighting radars from Sweden, and there was no need to set up any observation posts on the high ground for this thing. It is to track the enemy's artillery shells by radar, and then quickly and accurately calculate the opponent's artillery position.

And that's fast...... It is said that as soon as the enemy's first shell was discharged, the artillery radar had already calculated and sent the data to our artillery positions, so the enemy's shells had not yet exploded into our positions...... Our artillery shells were already fired at the enemy's artillery positions under the command of the artillery radar.

It is conceivable that in this way, the Vietnamese artillery will not even have time to run, and the Vietnamese artillery will be completely pressed and beaten...... It's almost over as soon as the cannon is fired.

Of course, it was a few years before this thing was introduced, and I think it was 83...... This is also the reason why the Battle of Laoshan was started in 84, you must know that at that time, our army's equipment has been fully updated, the infantry has Type 81 assault rifles, machine guns, and sniper rifles, tanks and armored transport vehicles have also been improved, and the artillery has artillery sighting radar...... That's the time to test out the new equipment and teach the devils a hard lesson.

But until then, it seems that we have to play the same old way.

"Battalion commander!" At this time, a correspondent saluted in front of me and said, "Commander Zhang asked you to go!" ”

"Hmm!" I nodded and beckoned to Xiao Chen, the driver who was smoking not far away, and Xiao Chen hurriedly threw away his cigarette, jumped into the jeep, and started the car to drive over.

This is the advantage of being a battalion commander, and the whole battalion, including the staff officers, is equipped with a total of five jeeps...... But this is also because of Commander Zhang's generosity, or it can also be said that our synthetic battalion is special, and an ordinary battalion can be equipped with a jeep, which is not bad.

Jumped into the car and thought about it, and then instructed the guard: "Go and call Zhang Wenwen too!" ”

"Yes!" The guard answered, of course he knew that Zhang Wenwen was referring to Zhang Fan.

After a while, Zhang Fan stood in front of me and shouted a report.

"Get in the car!" I say.

"Yes!" Zhang Fan didn't ask anything.

She was still a small soldier in front of outsiders...... It shouldn't be said that he is a small soldier, and the clerk is also a cadre, but my orders must be carried out unswervingly.

So sometimes I just think...... If one day I order Zhang Fan to lie in bed...... I don't know if she will carry out the order, or if she will do it.

Thinking about it, there was a reaction below, and I couldn't help but curse secretly and didn't dare to think crookedly anymore.

From this point of view...... This is another disadvantage of a jeep, and you can't do anything to Zhang Fan like you used to do in a car, right?

Soon Zhang Fan, who was sitting next to me, knew my intention to bring her, because this was the door to Commander Zhang's residence, and Zhang Fan would not know this road.

Soon the jeep stopped in front of Commander Zhang's residence with a brake, Zhang Fan jumped out of the car excitedly, ignoring the driver Xiao Chen and the guards who were behind us, took my hand and walked to the door, asking as he walked: "My dad called you here?" What did you call for? ”

"I don't know!" I said, "I think it's better to take you with me, you haven't been back these days, and I want to meet your parents!" ”

Zhang Fan nodded, because she was in a hurry to train during this time, she did not go home for a while.

Looking at Zhang Fan's face full of happiness, I couldn't help but smile bitterly in my heart...... Alas! This girl is so easy to satisfy, I'm just doing a favor.

But I soon found out that I had made a mistake...... Commander Zhang's face was a little surprised when he saw Zhang Fan, and then he found an excuse to break Zhang Fan away, it was obvious that Commander Zhang was looking for me on business.

So I knew...... You shouldn't take Zhang Fan with you next time.

"Come on...... Sit! Commander Zhang pointed to the rattan chair in front of me, handed me another cigarette, and asked, "How has the training been lately?" ”

"The progress is okay!" I said, "Some problems have been found and some problems have been solved, and they need to be strengthened!" In particular, the individual tactics of a company ......"

"Hmm!" Commander Zhang nodded: "There is no rush in the training, you can take your time, there is still time!" ”

Then he handed me a sample of the weapon...... At first glance, I saw that it was a submachine gun that looked similar to the 56 punch (the 56 punch was not much different from the wooden 81 bar in appearance), and even the folding army spur was retained on this picture......

"Isn't this a Type 56 submachine gun?" I'm pretending to be confused, I know in my heart that since Commander Zhang will show it to me, it will definitely not be 56 Chong.

Sure enough, I heard Commander Zhang say: "This is not a 56 rush, but a new submachine gun we want to build!" That's what you said last time...... A gun that combines the advantages of 56 and a half and 56 punches. But it's not finalized yet...... Now the upper echelons are arguing about this gun, you have fought a war, and you know better what kind of gun is needed on the battlefield, so I want to hear your thoughts! ”

It's so easy to do...... I have a barricade in my head, don't I?

But I pretended to look at the picture and said, "It's better if the bullet can be used in conjunction with the Type 56......"

"Hmm! weishenme？ What I said made Commander Zhang's eyes light up.

"Because our army has a great demand for ammunition!" I said, "If the bullet is not compatible with the Type 56 rifle, it means that we have to produce another kind of ammunition, which is a waste of a large stock of Type 56 ammunition on the one hand, and a shortage of ammunition on the other hand!" ”

"Hmm!" Commander Zhang nodded: "There is no problem with this, the result of our discussion is the same as what you said." ”

"The bayonet has been changed to a detachable one!" I said: "There are very few times when bayonets can be used in modern warfare, and the folding military stab is too heavy, and second, it cannot be used as a dagger, and it is very inconvenient to make a can or assassinate on the battlefield!" ”

Commander Zhang nodded again and did not speak......

In fact, I know that the fact that the military stab can be dismantled may be a kind of common sense for modern people, but in this era, a considerable number of people insist on folding the military stab in order to maintain the tradition of "bayonet seeing red", and there is a lot of quarrel for this. (To be continued......)
