War Military: From 1978

Chapter 70 Artillery Observation Methods

"Artillery reconnaissance, divided into five posts."

Half an hour later, after gathering again on the playground, the captain stood in front of everyone and said, "According to the organization, there will be three subjective officers and two side observers in a class.

There are two people watching from the side, one is the observer and the other is the cover person!

The three subjective roles are observer, covert personnel, and calculator."

After a pause, the captain took two steps and came to the object supported by two tripods.

This is the steering wheel used by our artillery

Carried by the supervisor and the observer, you will use this to observe the target during combat!"

Then he walked to the table next to him.

There are also a few items placed on it. The first one is something like a disc.

This is an abacus.

Carried by the calculator in the subjective trio.

After saying that, he took another step forward, pointed to the item on the table and said, this is the 861 portable command machine.

, which is what we call a walkie-talkie. It is usually carried by cover personnel and is used to communicate with each other and summarize data.

However, the subjective screener generally carries this step.

Radio 884!
The captain pointed to a radio station nearby that was obviously much larger than the 861 next to it.

"Doesn't it look much bigger?" The captain said with a smile, "Bigness definitely has its advantages!"

The captain explained, "This radio has an effective communication range of five kilometers, while the 861 radio only has an effective communication range of three kilometers. In actual measurements, it's even shorter. If the terrain is more complex, it might be only about one kilometer or even shorter."

It is obvious that the 861 command aircraft is definitely not enough if used for artillery command.

Next, Huang Tianzhi introduced several things on the table.

A pair of telescopes, a map, two poles, a compass, and a tape measure.

"These are what you will need to master and utilize in the third phase. Only by mastering these can you be considered a qualified artillery scout.

Of course, this alone is not enough!"

Huang Tianzhi walked back to the 861 command radio and the 884 radio station.

In war, keeping intelligence confidential is an important task. In the third stage, you will also need to learn to use secret codes to send messages or communicate directly.

He said a lot, but many people actually only have a vague understanding of it, especially the new recruits like Chu An.

They may know that radios and walkie-talkies can be used for communication, telescopes can be used to see far, maps can be used to read images, and compasses can be used to find directions.

As for the steering wheel, calculation computer, and the pole that looks like a stick, what are their specific uses?

Confused.

Of course, this is because training has not yet begun.

Soon, after the captain finished his introduction, he began to demonstrate how to use these things.

There are only two people: the captain and the instructor.

One of them acts as the subject, and the other as the observer.

It can be seen that the instructor first took the 861 command aircraft and ran to the opposite side of the playground holding a steering wheel, stopped outside the runway where the second company originally assembled, and set up the steering wheel.

The captain himself set up another steering wheel on the spot.

Finally, the captain picked up another pole and ran to a place more than ten meters away to insert it.

After that, he used a leather tape measure to measure the distance between the pole and the steering wheel that had just been set up, and then he began to operate the steering wheel.

Chu An and the others didn't quite understand what he did. They only saw him leaning over to look at the scope-like place on the steering wheel, then aiming it at the instructor's position, and then turning it to the place where he had just erected the benchmark.

At the same time, the instructor also made obvious moves.

He also seemed to be looking at the benchmark and captain here.

After just a moment, the captain took out the 884 radio headset, put it on, and loudly read out the value.

The secret number is 817. The secret number is 354.

As he spoke, he picked up a pen and paper and began to calculate.

Soon, he shouted again.

"Distance eighty-nine."

"Observe target number two!"

"Mil 1132." "Density."

After just a moment, after two more densities were reported, he picked up the pen and paper again.

The result was quickly obtained: "Distance 277 meters!"

To be honest, his operation confused many people. Although Chu An realized that the digits he reported should be the angle, he was not sure how to convert the digits into angles.

But he didn't have time to think about that now.

Because the captain looked directly at Chu An.

"First squad leader!"

"Here!" Chu An was stunned for a moment before responding loudly.

He has not yet adapted to the title of being the squad leader.

"Here's the measuring tape. Bring someone to measure the distance from my place to the cafeteria's main entrance. The others will follow and watch!"

He wants to verify the algorithm.

Chu An immediately stepped forward and took the measuring tape.

In fact, he wanted to say that it was not necessary.

As the team leader and instructor, the two were sent to teach them these things, and now a simple calculation would definitely not be wrong.

In this case, it seems a bit redundant to pull a tape measure over and measure it bit by bit.

However, he also knew what the captain was thinking.

Seeing is believing. Only when everyone is convinced can we continue with our work.

Soon, the measurement work began. Chu An and Liu Xi took turns pulling the tape measure and measuring alternately.

In less than ten minutes, the measurement work was completed.

Two hundred and seventy-seven point eight meters.

The error is less than one meter.

But if you consider the slight deviations along the way, then this deviation is obviously nothing.

The value the captain just reported is obviously accurate.

"This is called the intersection method, and it's how our artillery accurately measures the enemy's range and elevation!"

After the measurement was completed, the captain said loudly: "The error you are measuring now is the error of the tape measure. If we measure it in our way, as long as the method is correct, the basic distance will not be wrong either!"

"report!"

At this time, Chu An, who had been suppressing his curiosity, couldn't help but report it.

"Speak!" The captain looked over.

"Captain, may I ask how you calculated the "secret position" you mentioned?"

"Haha, good question!"

He looked at the others, then looked directly at Chu An and said with a smile: "Actually, this mi is to divide the 360-degree circle into 6,000 equal parts."

After a pause, he continued, "If we do this, we can make our calculations more accurate!"

"Six thousand equal parts?"

Chu An's brain was working fast at this moment.

In just a moment, he figured out that each value of the 360 degrees was now equal to 0.06 of the original value.

The value is accurate to two decimal places.

In this case, the original forty-five degrees would be equal to seven hundred and fifty.

"Okay, let's go back now and teach you how to use these instruments and equipment!"

The captain didn't care what Chu An thought and turned around after he finished speaking.

Behind him, a group of new recruits and veterans hurried to catch up.

Everyone is curious about the new equipment, especially now that these things look so awesome.

Just take a picture and you can get the exact distance from a distance.

It’s so cool. Now that I hear that I can get started right away, who can resist it?

Everyone is a little impatient.

　enWhat is written in the book is true. I have taught you this. But don't go and shoot cannons secretly if you have nothing to do. If you do, don't say I taught you that!
