Cedar shed front. Zhang Rentian was personally aiming at a Type 99 tank with an anti-materiel sniper rifle, when Wang Shan, the guard next to him, suddenly shouted: "Brigade seat, **, **!" Then they pounced on him and crushed him behind the sandbag fortifications.

The shooting yuan obtained by the 1st Special Artillery Brigade was provided by Zhang Rentian. The Japanese offensive was fierce, although Zhang Rentian promised Ni Chunsheng that he would be able to withstand the Japanese attack and ensure that the Japanese army could not enter the safety line, but he did not have much confidence in his heart. Therefore, the shooting Zhu Yuan he reported to Ni Chunsheng was frequented, and if the 1st Special Artillery Brigade really adjusted the angle to fire according to this data, there would definitely be a situation of accidental bombing. Wang Shan didn't know that Lu Dao Brigade had already given birth to the determination to die with the devil, but experience made him feel the danger, and he instinctively made the most correct choice, which also reminded Zhang Rentian.

Zhang Rentian knew much more about rocket artillery than Wang Shan, he pushed Wang Shan away, raised his upper body and shouted left and right: "Get down!" Get down! Brothers, get down! ”

The strike of rocket artillery is characterized by area coverage. The "Thunderbolt" rocket is currently used with a total length of 1.13 meters, a caliber of 280 millimeters, and a total combat weight of 43.5 kilograms. The combat part is divided into a collision ignition device, and then a charge section consisting of three cluster bombs from top to bottom. According to the tests conducted by the Cadet Research and Development Institute, once a rocket is successfully exploded, its coverage radius can reach 80 to 100 meters on average, and the effective killing radius can reach 60 to 80 meters.

Eight hundred and sixty-four rockets all rose into the air in ten seconds, forming a meteor shower and flying towards Wucun Town, when this cloud of fire flew over the heads of the retreating Wucun Town and the Self-Defense Members, the townspeople and Self-Defense Forces who did not know what it was were were frightened inexplicably, and many of them unconsciously knelt on the ground with weak knees, and their mouths began to recite words: Guanyin Bodhisattva who saves suffering......

The rockets flew at more than twice as fast as the shells, averaging only about 420 meters per second. The artillery position of the 1st Special Artillery Brigade was about 8,000 meters away from the front line of the cedar shed, which means that it took 20 seconds from the time the rocket successfully took off to reach the target.

Twenty seconds is enough time for a healthy young man to run 150 meters. But for the devil soldiers at the forefront, this distance is far from enough. Just as Zhang Rentian shouted loudly for his brothers to lie down, the officers of the 9th Tank Wing, Quzhou Security Brigade, and 9th Infantry Wing, which were at the forefront of the Japanese army, also shouted loudly, ordering their subordinates to lie down to avoid the shelling. Behind them, the devils of the 115th Infantry Wing were in a mess, and everyone watched in horror as the red cloud flew closer and closer, and instinctively wanted to turn around and run away, but when they saw the bright sabers in the hands of the officers, they quickly stood up again.

In the rear, after the initial panic, Sakai Naoji and Obaov thought about countermeasures with a calm face, and a few seconds later, Sakai Naoji first came up with countermeasures, while he asked the officers and soldiers directly under the brigade headquarters to find hiding places on the spot to avoid the shelling, and then personally urged the chief of staff Tachibana to send a telegram to the division headquarters, and he dictated the telegram: Our department was ambushed by artillery above the brigade and regiment level, and if we forcibly launch an attack, I am afraid that the casualties will be too large, please rule.

The fire cloud flew closer and closer, and the range of the attack gradually became clear, Sakai Naoji and Obaofu found that the shell landing point was at least two kilometers away from them, and their hearts were relieved and at the same time they looked at the front line of the cedar shed with worry, and their hearts were beating wildly.

The Japanese army has strict military discipline, and once the commander has an order to pass it on, the officers and soldiers at the bottom will meticulously carry it out. The Japanese army has won many classic victories by virtue of the strict military discipline of advancing and retreating, and gradually the upper and lower levels have developed a superstitious psychology towards the capital, and they have worked extra hard to carry out their orders. However, on the front line of the cedar shed, seeing that the roaring fire clouds were overwhelming, if they continued to lie on their stomachs, they would definitely not escape the fate of being hit, many devils had a psychological breakdown, suddenly screamed, and then got up and ran towards the rear where they thought they were safe. Some people took the lead, others were infected, and subconsciously felt that running away was the best way to vent their fears, and they got up one after another to join the ranks of the escapees.

"Eight squares! Get down! "Come back!" "Eight Grids!" The officers shouted and cursed, and some even fired warning shots, but it did not stop more and more people from fleeing. The devils didn't know that it was a rocket that was thrown at them, and they didn't know what the difference was between a rocket and a normal shell. However, this does not prevent them from making the best choice based on experience. Twenty seconds - fifteen seconds - five seconds...... The fire cloud flew quickly and slowly, and for those devils who were still lying on the ground, the psychology of waiting for disaster to strike made them feel like they were living like a year. And when the first rocket hit the ground and exploded, many people slowly exhaled a breath, and the fear in their hearts was much lessened - they thought: But that's it!

The scene of the salvo of fifty-four rocket launchers was indeed terrifying, and the weaving cloud of fire gave people an extremely shocking audio-visual experience. In stark contrast, when the rocket hits the ground, the movement is too small – is that really the case? A small mushroom cloud rose up, "boom", there were burning fireballs scattered in all directions, many devils instinctively meant that they were safe away from the center of the explosion, but the fire suddenly exploded around them - the next moment, the fireballs exploded, and the continuous explosion sounded, many devils were inexplicably engulfed by the flames of the explosion, hit by shrapnel, and instinctively screamed at the same time, they didn't know how they became victims.

A cluster bomb mother bomb consists of 60 submunitions, one rocket explodes, and 180 submunitions are thrown out, except for the dud, the others will explode in three or four seconds. The movement caused by the explosion of a submunition is actually very small, not even as good as the gunfire of an anti-materiel sniper rifle, but the dozens of steel balls inside are real killing weapons - the pressure reaches more than a dozen or even twenty gipascals, and it bursts out under the impetus of the hot air generated by the explosion, which can penetrate a person's body within seconds, and even directly tear a person to pieces.

The first appearance of "Thunderbolt" gave Sakai Naoji enough face, and none of the 864 rockets were dumb.

There is a reason why Zhang Rentian chose the cedar tree shed as the last sniper front. If you look at it from the air, about 1,500 meters from Wucun Town to the cedar shed, it is a standard horn. Because of the mountainous terrain, the width that could be used for marching when Wucun Town came out was about 1,200 meters, but when it came to the cedar shed, it shrank to about 200 meters.

Because of this geographical feature, Ni Chunsheng was able to lengthen the depth of the artillery bombardment when he commanded his subordinates to adjust the firing of Zhu Yuan, so that although it was only a salvo, the strike range of the 1st Special Artillery Brigade was still able to cover the western part of Wucun Town, and then with just one salvo, almost all of the 1st tank wing and 2 infantry wings plus a puppet army brigade in front of the Japanese army were covered.
