This kind of artillery is extremely lethal to the Qing army, and it is not a good idea to get rid of it and send death squads to attack the enemy's artillery positions, because the artillery positions are often in the rear of the enemy, with multiple protections, and many times the death squads become "death squads".

The Qing army retreated all the way along the communication trench, and the Japanese army quickly occupied the first defensive position, and the Japanese soldiers who entered the trench let out a high-pitched cheer, as if they were intentionally shouting to the Qing soldiers, Lin Yuan turned around and saw the Qing soldiers hanging their heads one by one, squatting in the trench with their guns, like a group of frosted eggplants.

Lin Yuan turned on the communicator, found Yang Yu, and said, "I need air support, I have the enemy's artillery positions here, you take off a fighter plane and blow them up." ”

Yang Yu said: "Understood! ”

Lin Yuan said again: "I hope you can come as soon as possible, so don't hang the millimeter-wave radar pod." "The J-25 carrier-based fighter on the Beijing ship is an air superiority fighter, and the airborne radar used works in the centimeter band, which is the length of the band, which is unable to accurately locate tanks, artillery, and vehicles on the ground.

Yang Yu asked, "Then how can I discover the enemy's artillery position?" The drone unit provided me with a very accurate position, and the enemy has the possibility of moving artillery positions, so I need to search after I get to the battlefield. ”

Lin Yuan said: "Isn't the J-25 equipped with infrared detection equipment? It was more than enough to discover the artillery positions of the Japanese army! ”

Yang Yu said: "Okay, I'll fly over as soon as possible." ”

Yang Yu then piloted a fighter plane and flew towards the Japanese artillery position at the fastest speed.

Lin Yuan thought to himself: "Although the air strike I summoned can blow up the Japanese artillery, but the Japanese artillery position is too far away from here for most Qing soldiers to see, how can I use this air strike to boost morale?" When they saw that the artillery that had been pressing them down had been blown up, their morale must have been high! ”

At this moment, there was another burst of cheers from the Japanese position, and more than twenty war horses, pulling artillery and ammunition, walked in their direction.

The Japanese artillery stopped two thousand meters away and began to prepare for the firing position, and the Japanese infantry looked at their heroes and gathered around them proudly, although they did not understand how advanced this artillery was, they still talked happily, because they had just won a great victory, the Japanese commander did not prohibit his onlookers, but thought that it would boost morale!

The artillery is a big guy, even if it is two thousand meters away, it can faintly see a silhouette, and the soldiers of the Qing army also looked over there curiously, Liu Dart asked unconvinced: "Lin Shuai, is that the artillery of the little devil?" Why is there a big tube on the body? ”

Lin Yuan knew that the big cylinder was an anti-recoil device, and thought that Luo Lao guessed well, the Japanese artillery really used a gas-hydraulic anti-recoil system.

Lin Yuan saw that the Japanese army had put the artillery under the noses of the Qing army, and thought: "This is really a nowhere to find the iron shoes, and it takes no effort to get them, if we blow them up under the eyes of our soldiers, all the anger we suffered before will be out!" ”

Soon, Lin Yuan received the news that Yang Yu had arrived on the battlefield, and the infrared detection system of the J-25 was an advanced two-color detection system, and the detector in this detection method could respond to two different bands of light, thereby suppressing complex background infrared information and improving the detection effect of various temperature targets.

Yang Yu flew to the battlefield and turned on the infrared detector, but ten minutes passed, and no high-temperature target was found on the ground!

Yang Yu's heart was a little panicked, he knew that when the cannon was fired, due to the combustion of the propellant and the friction between the shell and the body tube, the temperature of the body tube was very high, sometimes it could even reach hundreds of degrees, and such a high temperature was easy to see on the J-25 sensitive infrared detector.

Lin Yuan was also a little anxious, and he asked Yang Yu, "Why don't you attack yet?" ”

Yang Yu said: "I can't find the location of the artillery!" ”

Lin Yuan said: "They are two thousand meters in front of me!" However, this relative relationship was meaningless, because Yang Yu could not accurately know the location of Dao Lin Yuan.

At this moment, from the telescope, Lin Yuan saw that the Japanese artillery began to disperse the onlookers, Lin Yuan knew that the Japanese army was about to carry out a new round of artillery bombardment, and he suddenly thought: "As soon as the Japanese army fires the artillery, Yang Yu will be able to discover them, and blow up the enemy's artillery when we are suppressed the most, so that the morale will be stimulated, won't it be greater?" ”

Lin Yuan then ordered: "Everyone is lying down in the trenches, and they are not allowed to move around at will." ”

Immediately afterwards, Lin Yuan gave another unbelievable order: "Listen carefully, in a while, there will be an explosion on the Japanese position!" ”

Everyone was puzzled, how could Lin Shuai allow the Japanese army's position to explode? Before I had time to ask questions, I heard the sound of cannonballs, and then the earth kicked up by the cannonballs rained down on the people in the trenches!

Since the caliber of the gun is only 75 mm, the propellant and the warhead are installed together, that is, the fixed charge, which undoubtedly increases the speed of firing.

Another excellent design of this gun, which also guarantees its high rate of fire, is the rotary eccentric screw bolt, which can be opened with a simple movement and exited the cartridge inside.

The gunners kept firing the cannon, and the rate of fire of twenty-five rounds per minute gave them almost no time to stop, and the body of the gun was quickly hot, and they could even feel the heat coming from it!

They still don't know that this hot body is the life talisman of the king of Hades!

The J-25 fighters, who were monitoring the entire battlefield in the sky, quickly discovered the Japanese artillery positions on the ground!

The caliber of the aviation cannon is too small, the explosive power is insufficient, it is not cost-effective to use air-to-ground missiles, and the accuracy is not too high when using aerial bombs, so Yang Yu chose rockets to bomb the artillery positions of the Japanese army, and there are mainly three calibers of aviation rockets in our country, this time the J-25 uses 90 millimeters, and carries a total of 40 rockets, which are installed in the rocket launch nest on the external attachment points under the two wings.

Yang Yu stabilized the throttle stick, at an altitude of three thousand meters, the steering stick dived towards the ground, when it was one thousand meters away from the ground, Yang Yu pressed the launch button, and the rocket launch nests on both sides were launched at the same time, and every other second, there was a rocket, like a bird of prey that pounced on the prey, leaving the nest!

At the moment when the rocket leaves the nest, the folded tail flicks off instantly, and the tail is installed at an angle to the axis of the projectile body, so after the tail is opened, the high-speed flowing gas can be loaded with a huge moment on it, so that the rocket rotates at high speed around the axis of the bomb body!

This rotation kept the trajectory of the rocket stable, and a few seconds after flying out, the engine on the rocket ignited, and a large amount of high-temperature gas sprayed out of the tail nozzle, propelling the rocket, carrying death, towards the Japanese position.
