Chapter 779: Mixed Feelings at the Institute of Research
The soldiers didn't care at all that 4 of the 3 missiles were missed. What they cared about was the one that hit the target.

Seeing the enemy plane spinning and falling, the four-wheel drive off-road truck quickly made arrangements: "We will continue to be alert, you go to the place where the enemy crashed."

They still had to maintain vigilance, which was a basic quality. They quickly divided the work, and the people in the GAZ vehicles did the same as their comrades at the front line, carrying their guns and sitting on the vehicles and moving forward.

Not long after we got in the car and drove out, the helicopter fell to the ground. It was several hundred meters high and fell very quickly.

Fortunately, there was no obstacle between the helicopter and the car, and the four soldiers quickly arrived at the burning helicopter.

The helicopter was tilted in the sand, its broken blades still swaying slightly, flames blazing, and crackling sounds coming from it.

Looking through the porthole of the helicopter's passenger compartment, there was a shadow inside that kept shaking. I couldn't tell whether it was fire or a struggling figure. The sound of burning was too loud and no human voice could be heard.

Even if there was a human figure, they couldn't put out the fire because it was too big.

A soldier picked up the fire extinguisher from the car and wanted to pull out the safety pin, but he looked at the flames rising into the sky again and stopped.

They just spread out in groups of two and searched around to see if there were any lucky people who were thrown out when they fell to the ground.

They shouted while searching. It didn't matter what they shouted. What was important was that they shouted. In this environment, the lucky ones would not dare to hide. If they were caught, they would definitely not die, but if they hid, they would be really dead.

But unfortunately, no, not a single lucky person.

They had no choice but to remain alert and wait for the fire to go out.
-
The Engineering Corps Headquarters in the capital was the first to receive the news.

"Two helicopters of unknown origin were shot down at the western airport on the plateau?"

"Yes, two Mi-4s, each with the same configuration, two crew members, 13 armed personnel."

"Can you confirm the origin?"

"Judging from the people and equipment, they should be from San'er's side, but it's hard to say where they belong. The local troops have searched carefully and found no items that could indicate their identity. In addition, the aircraft and personnel were burned beyond recognition in the fire, so it is difficult to identify them."

"Well done, I'll report it right away!"

"Oh, there is one more thing. Local herdsmen informed our troops that they found the wreckage of a helicopter in the mountainous area west of the airport valley. The comrades in the army have gone to take a look, but it is a mountainous area with no roads. We have to wait and see what the situation is. This mountainous area is not far from the upper reaches of the Xiangquan River."

"It seems that the enemy may have three helicopters coming in along the Xiangquan River Valley."

"It's very likely. We've studied it and it's very difficult for helicopters to get into that area except for that route."

"We need to inform the foreign affairs department about this matter, and they will handle the negotiations with the other party."

Every profession has its own expertise. The army is responsible for killing but not burying. As for how and where to bury the dead, it depends on the outcome of the dealings between the foreign affairs department and the other party.

Soon after, not only the foreign affairs department in charge received the news, but the Defense Work Committee also received it. What they received was complete news, including the process of the shooting down and the Mi-4A that crashed into the mountain, which has now been clearly accounted for.

The leader of the Defense Work Committee looked at the report from the Engineering Corps Headquarters and licked his teeth.

"Wow! The portable air defense missiles developed by the Missile Research Institute and Gao Zhendong are incredible! Six missiles shot down two helicopters suspected to be from Sindhu in one fell swoop, killing all 6 people on board. In addition, another helicopter suspected to be from Sindhu crashed, killing all 30 people on board. On this day alone, three helicopters of the Sindhu people were destroyed, almost half of a company's people." The leader laughed as he read the report.

As a leader, the name for Zang San is much more formal, Sindhu.

Of course, strictly speaking, this translation is not very nice, but fortunately it is the official name, a translation from ancient times. It is estimated that the origin of this translation is related to biology in addition to pronunciation, and perhaps it combines some physiological feelings?
In short, at least faith and communication are both present.

As for the word "Ya", when we named our surroundings in ancient times, most of them had nothing to do with this word. Some names even had the radical "Ya", such as the "Di" in "Yi Di" and so on. How much importance can be attached to names with this radical?

"They are still so dishonest, and they suffered a great loss this time. Leader, what do you think they are thinking? They dare to sneak into the hinterland of dozens or hundreds of kilometers? Do they really think we are decorations?" The chief engineer laughed.

The leader also shook his head in confusion: "How can I understand this? Even the people above me can't understand it."

The chief engineer also laughed: "You are right. However, in this operation, the hit rate of this portable air defense missile does not seem to be consistent with the test at the shooting range. Only 6 out of 2 bullets hit the target. The hit rate of 33% seems a bit ugly." The improved portable air defense missile has increased the single-shot hit probability in Syracuse to between 75% and 80%. This 33% seems outrageous.

Unexpectedly, the leader smiled and shook his head: "Look, a one-third actual combat hit rate is not ugly at all, it looks very good!" This is the difference between people who have actually led troops and pure technical personnel. Some seemingly outrageous data fluctuations are not a big deal at all in his view. The important thing is that no enemy plane escaped, and the key problem is solved.

Moreover, the leaders knew very well that it was impossible to achieve the same results as in the shooting range under actual combat conditions.

The Russian Arrow-2 portable anti-aircraft missile had an actual combat hit rate of just over 10%. Although the technical level of that thing is much lower than our current one, it is still very telling.

The chief engineer thought about it and did not object to the leader's opinion. He just said: "Then I will forward the detailed process of the operation to the Institute of Guidance and Research and let them see for themselves whether there is room for further improvement."

This is a mature and prudent statement. I will not draw any conclusions. I will tell you the process and you can think about it carefully.

The leader thought about it and nodded.

The portable air defense research team of the Institute of Navigation and Research was still conducting experiments in Syracuse when they received the notice and were dumbfounded when they saw the combat process.

It's a good thing. No matter what the hit rate is, this new weapon, which is still in the experimental stage, has successfully shot down two enemy planes and two helicopters with six missiles. Putting aside the hit rate, both the actual combat effect and the cost-effectiveness are quite good, especially the latter, which makes them laugh out loud. It's worth it!

However, only 6 of the 2 shots hit the target. In particular, the flight trajectories of the four shots that missed were described to be very strange. They looked a bit like the previous dropped bullets, but they shouldn't have happened. A similar situation had never occurred in Snow City before.

A group of people began to analyze and had all kinds of ideas.

"Is it because the temperature on the plateau is too low, causing a problem with the control circuit?"

Unlike the crazy DIY people decades later who poured liquid nitrogen into the CPU to pursue extreme overclocking, in fact, the circuit cannot be too hot or too cold. Some fruits are easily frozen to death, which is related to the circuit in addition to the battery.

But this idea was quickly overturned.

"It's unlikely. The temperature in Snow City is not high. I just checked. The lowest temperature in the combat zone is not much worse than the environment in Snow City. Moreover, the lowest temperature does not occur during this combat period."

"Could it be caused by lack of oxygen? It's altitude sickness." A comrade had a very creative idea. He was not an engine expert, so he was more imaginative when thinking about the problem.

This idea was immediately overturned: "How is that possible? How can a solid rocket engine be used for high-reverse propulsion? It's not an air-breathing engine."

“Is that a magnetic field?”

"Without local geomagnetic data, we cannot determine the magnetic field conditions, but geomagnetism has no effect on our guidance system. I am sure of this. Even the gas rudder is made of tungsten-molybdenum alloy provided by General Gao, so it will not have any theoretical impact."

There is really no relationship between the magnetic field and portable air-to-air missiles. Not to mention that the geomagnetic intensity is not strong, even if it is strong, it still cannot affect the state of the air-to-air missile.

"The sunlight is reflected many times by the snow-capped mountains, causing some changes in the light parameters. Will this change affect our guidance head? Or is it that the light spectrum on the plateau is different from that in Snow City due to the sky? At least the ultraviolet rays are much stronger than down there, and we all know this."

This sounds a bit mysterious, but it has now become the most likely scenario.

"What you said seems to make sense, but the dual-color seeker has already taken ultraviolet light into account. So what are the remaining changes or which bands of light are causing them?"

A group of people racked their brains and discussed for a long time, but still could not come to the point. There was no other way, this was actual combat. It was said that several missed missiles were found, but they all successfully self-destructed. Except for the engine casing, there were not many wreckages worth studying.

This may be considered good news, the self-destruct device was successful...

Mr. Li saw that there was no conclusion after all the discussion, so he decisively ended the topic.

"So, now everyone can only rely on guessing. We have to do it on two legs. First, we will try to simulate the combat environment of the snowy plateau in Snow City to see if we can reproduce the problem. Second, we will wait for the wreckage they found to be sent back to see if there are any discoveries. Even if it is the second half, there will be some information."

Everyone responded and started working. If this problem is not solved, it will definitely be a thorn in our side. This is where our equipment is difficult. There are too many things we need to consider and too many environments to adapt to. Many conditions are even completely opposite. If we take care of one, we can't take care of the other. It is very troublesome to take care of both.
