Artillery is known as the king of war, and the suppressive power and cost-effectiveness ratio of artillery are incomparable to missiles, so Lin Yuan did not ignore the development of artillery when organizing experts to develop advanced fighters, high-performance radars and high-power missiles, although now Lin Yuan's troops are equipped with 122mm self-propelled cannon howitzers that have been unique in the world, but Lin Yuan was not satisfied, but let the arsenal come up with a more powerful 155mm howitzer.

Don't look at the aperture only increased by 30 mm, but the volume and radius are cubic, the diameter increases by 30 mm, and the increase in volume is 30 mm cube! The charge has also increased dramatically! In addition, the barrel of the 155-mm howitzer is relatively long, and the shell can be made very long, so the charge is larger.

However, this 155 mm howitzer has a fatal shortcoming, that is, it is too heavy, the weight of the whole gun is as high as fifteen tons, and the weight is weak in maneuverability.

At this time, heavy snow fell in the northeast, and in some places the snow reached knees, in this weather condition, if the 155mm howitzers were forcibly dispatched, it would be tantamount to a disaster, so they all hid in the base, and the Japanese army actually approached Yanji, which gave the 155mm howitzers a chance to shoot, because they could maneuver along the high-quality road newly built by Lin Yuan.

The 155 mm howitzer was dispatched under the order of Lin Yuan, and maneuvered along the road outside Yanji to the defensive position, and immediately changed from the marching state to the combat state after arriving at the position.

However, the 155mm howitzer is equipped with a state-assisted replacement system, which has its own engine and can help the artillery complete a rapid change, so the 155mm howitzer only took 20 minutes to complete the state change, and the commander gave an order, and the artillery group launched a bombardment to the depth of the Japanese army.

The artillerymen who operate this type of artillery are basically transferred from the 122mm plus howitzer unit, although they are used to hearing the shocking sound of the 122mm plus howitzer, but the sound of the 155mm howitzer still makes their hearts tremble, because it is so amazing!

The moment the propellant ignites and the cannonball rushes out of the chamber, one can feel the whole ground shaking, and despite wearing shock-isolating earplugs, you can still hear a terrifying loud noise!

The artillery shell crossed the defensive position of Lin Yuan's troops and exploded in the depth of the Japanese army, the formation of the Japanese army was very scattered, so the shell did not directly hit the tank or auxiliary vehicles, despite this, the explosion effect still shocked the Japanese army, Lin Yuan's troops fired a blasting bomb with a delayed fuse, this kind of blasting bomb exploded deep into the ground, and the soil raised was enough to bury a person alive underneath!

For a while, the white snow, red flesh and black soil were mixed together, and the Japanese army was almost about to collapse, and as soon as Kumamoto saw that he could not capture the position of Lin Yuan's troops, but also suffered from Lin Yuan's artillery, he immediately ordered: "All retreat." So the Japanese retreated in a hurry, and arrived at Kaishantun a few hours later.

Lin Yuan's troops cheered when they saw the Japanese retreating, and at this time they found a scene that made them even happier: that is, the tanks whose tracks were blown off after climbing the triangular cone were all left behind by the Japanese!

The commander of the defenders immediately reported the situation to the commander Zhou Xiao, who wanted to order the troops to go out and snatch back the fifteen tanks, but suddenly remembered the situation that Zhang Yun had reported to him, and the Japanese tanks chose to self-destruct when they were cornered!

Zhou Xiao immediately thought: "Will the Japanese army put a time bomb in the tank?" Then our people would have been blown up in the past. ”

Zhou Xiao then said: "Don't go over first, in case the Japanese tank is installed with a time bomb, you will be in danger, can you find a way to find out if there is a bomb installed in the turret?" ”

The commander of the defenders said: "We can't see the inside of the Japanese tanks now, and we don't know if the bombs have been planted." ”

Zhou Xiao said: "Then have you seen anyone return to the tank again?" ”

The commander of the defenders said: "Our men were in the trenches at the time of the shelling, and no one paid attention to the Japanese tanks, so we didn't know either. ”

Zhou Xiao said: "Okay, for the sake of prudence, you just wait for a while, and wait until you are sure that there are no explosives in it before you go over." ”

The defenders did not send troops, an hour passed, the tank did not move, another hour passed, there was still no movement, the commander of the defenders then reported to Zhou Xiao: "The enemy tank has no movement, we think there should be no time bomb inside, if there is a time bomb, the time will not be so long, two hours, enough for us to defuse the bomb." ”

Zhou Xiao thought for a while and said, "Have you considered the possibility of the Japanese army using trigger bombs inside the tank?" As soon as you open the hatch, the bomb will be detonated. ”

The commander of the defenders said: "With this in mind, we brought in an endoscope from the technical company, and we put the endoscope into the tank from the machine gun firing hole in the Japanese turret, used the endoscope to observe the situation inside the car, and then opened the hatch after making sure that there were no bombs." ”

Zhou Xiao said: "Very good, act as soon as possible." ”

The defenders immediately went out, and the technicians carried the endoscopes to an enemy tank, but just as the technicians approached the tank, the gunshots suddenly came from the tank's firing port, and the technicians were caught off guard, and more than a dozen people were immediately knocked to the ground, and the others hid behind the anti-tank triangular cone.

At this moment, I saw that the main gun of the Japanese tank slowly moved, aiming at the anti-tank triangular cone where the technical personnel were hiding, and as soon as the cannon sounded, a grenade exploded near the triangular cone, and none of the technical personnel hiding behind the triangular cone were spared.

As soon as the other triangular cones saw this, they immediately rushed into the nearest trench, knowing that as long as they rushed into the trenches, the Japanese tank guns and machine guns would not be able to hit them, but as soon as they left the triangular cone, the machine guns and main guns of the other tanks rang out, and more than 50 technicians fell to the position in an instant!

The defenders of Lin Yuan's troops present were stunned, no one thought that there were people in the Japanese tanks, most of the Japanese troops had withdrawn, and these tankers stayed in the tanks that had lost their mobility, and there was only one end - death! Although the Japanese tanks had heavy armor, the armor was dead, the attacker was alive, and the armor certainly could not withstand all kinds of attacks.

The defenders of Lin Yuan's army saw that more than 50 technical personnel were all killed, and their anger immediately surged, and the defender commander immediately told Zhou Xiao the news, and Zhou Xiao immediately ordered the artillery unit to concentrate fire on the Japanese tanks.
