Soon, Sun Erwei sent a telegram to order M1 anti-aircraft guns from his superiors.

But the focus is not this, the focus is on observation results.

Sun Erwei's superior, Colonel Smith, replied with interest when he received the telegram: "It seems that the Chinese have convinced you!"

"Yes!" Sun Erwei replied: "We thought we knew them and understood our weapons, but... we didn't know, Colonel!"

As he said that, he reported Wang Xuexin's tactics.

Colonel Smith also agreed after seeing the tactic, saying: "It seems that we are only discovering part of the function of these weapons, and in certain specific circumstances, it may play an unexpected role!"

After pausing, Smith asked again: "How should I report it? Are they worthy of our assistance?"

"I'm not sure, Colonel!" Sun Erwei replied: "Their current situation is to make the best choice based on the existing conditions, and they are very good at this. I don't know if they can control it once they have more equipment!"

Colonel Smith understood what Sun Erwei meant.

The advantage of having less equipment is that there is less equipment. For example, the Eighth Route Army's tactic of using M1 anti-aircraft guns was to capture the Japanese's position with clear goals.

But if there is too much equipment, this prediction will not exist, and what is needed then is regular combat.

However, Sun Erwei added: "But I think they are worth our attempt, Colonel! I mean, they can invent these practical and unexpected tactics in this case, does that mean... if there is more equipment, they can invent more tactics! I am looking forward to this!"

Sun Erwei is telling the truth. Wang Xuexin’s tactics invented are very interesting, but unfortunately these tactics cannot be used... Eagle Sauce has radar, so of course there is no need to use tanks to attract enemy aircraft like the Eighth Route Army.

So Sun Erwei thought, if Ying Jiang could give the Eighth Route Army more assistance and let Wang Xuexin invent some modern tactics and some tactics that could be used by Ying Jiang, would that be helpful to Ying Jiang's future war?

Colonel Smith disagreed.

"Forget it, Captain!" Smith called back: "We cannot hope that a group of people who even have planes and warships can provide us with constructive opinions. We just want to know whether it makes sense to assist the Eighth Route Army!"

"Yes!" Sun Erwei replied: "I will continue to observe them!"

When Sun Erwei returned to Wang Xuexin's battalion, he did not tell Wang Xuexin what he observed. He just said lightly: "I have asked them to send the M1 anti-aircraft guns, twenty. Considering the urgency of your needs, we will dismantle them and air transport them. There are still 10,000 shells with him, which will probably be shipped in a few days!"

Wang Xuexin nodded with satisfaction, then asked while flipping through the documents in his hand: "Can you talk about your radar? It can really see a target worth dozens of kilometers?"

Wang Xuexin asked this just to make a foreshadowing of the radar in the future so as not to explain it if it was leaked.

"Of course!" Sun Erwei nodded proudly: "This is amazing, isn't it? But I can't tell you how far it can see. This is a military secret!"

Wang Xuexin expressed understanding.

This should indeed be a military secret. If the enemy knows the radar detection distance of Yingshang, he will fly at a low altitude outside this distance to avoid its reconnaissance.

However, Wang Xuexin could guess that the detection distance should be around thirty to forty kilometers.

The reason is that Sun Erwei said that they developed an anti-aircraft gun that can strike 25 kilometers... Without a longer detection distance, the range of this anti-aircraft gun is meaningless.

"How does it work?" Wang Xuexin asked again: "I hope to know roughly its principle!"

"Say that!" Sun Erwei hesitated for a while and tried to explain it in easy-to-understand words: "It can emit a sound wave, which will be reflected back when it hits an object and is received by the base station. So we can calculate the distance of the target from the time it receives and the speed of the sound wave!"

Wang Xuexin raised his head with interest: "What do you mean is that it can detect the distance of the target?"

"So that's it!" Sun Erwei nodded.

This is not a secret. Many countries know that there are radars, and the Japanese are no exception, but the Japanese's radar is relatively backward.

"Interesting!" Wang Xuexin smiled: "I was still considering the issue of anti-aircraft artillery shells just now. Do you think the radar technology... can it be used on shells?"

"What does it mean?" Sun Erwei asked in confusion.

"Look!" Wang Xuexin said: "Anti-aircraft gun shells need to be manually adjusted to the delay time, which will lead to many problems and directly lead to the low hit rate of anti-aircraft guns."

Sun Erwei nodded. Of course he knew this. This was a big problem for anti-aircraft guns, so the loader is often the most important member of the anti-aircraft gun group... The loader is responsible for adjusting the delay fuse, and how long it takes depends entirely on his experience.

He must determine the height of the enemy plane, then convert it into time according to the height, and then adjust the shell fuze.

As long as one of these errors occurs, if there are fewer or more calculations or if the calculation speed is not fast enough, the shells will not hit the enemy plane.

Therefore, the hit rate of anti-aircraft guns is an average of 2,000 shells to hit one.

But Sun Erwei didn't think there was any problem with this. They have always fought like this. In order to make up for this defect, they can use other methods.

For example, if the fire rate of anti-aircraft guns is increased, the M1 90MM anti-aircraft gun can fire 20 shells per minute, and the hit rate will naturally be higher if there are more shells.

For example, radar can be used to cooperate with anti-aircraft artillery troops, which can increase the hit rate when hitting enemy aircraft outside the visual range.

Wang Xuexin continued: "I mean, since the radar can detect the distance of the target, why don't we create a fuze? This fuze is a small radar. After it is launched with the shell, it constantly detects its distance from the target, getting closer and closer... When the distance goes from near to farther, it will be a 'boom'..."

As he said that, Wang Xuexin raised his head at Sun Erwei: "In this way, we don't need to adjust the delay time. It not only saves the loading time of anti-aircraft artillery, but also increases the hit rate of shells. What do you think?"

Sun Erwei immediately widened his eyes and nodded blankly.

After a while, I suddenly screamed: "This is great, Wang! This idea is great... I will report this idea to them immediately and prove its feasibility! God, this is simply a miracle!"

As he said that, Sun Erwei even forgot to say goodbye to Wang Xuexin, turned around and ran towards his residence.
