The Japanese troops in front of Zhang Wei did not stop moving forward because of the platoon guns and light machine gun fire of the preparation battalion, and all the Japanese troops who launched the assault attacked forward under the rain of bullets, or continued to advance, or fell to the ground with bullets, and the Japanese army's forward was only less than 40 meters away from the river dam, and at this distance, the rifle shooting accuracy of the Japanese army also improved, and the officers and men of the reserve battalion in the river dam position began to suffer casualties caused by rifle hits. Ｘ

"Boom, boom." After two explosions, less than 10 meters to the left of Zhang Wei, two soldiers of the third company were killed, and their bodies were thrown out of the trench and rolled down the embankment slope.

"Fuck it, shit." Li Changgui scolded, and used Liao Thirteen in his hand to knock down a grenadier in the distance.

"Sir, why don't you shoot the heavy machine gun in the back?"

Zhang Wei did not answer, and fired a shot at the Japanese army, and the Japanese army in front of the battle continued to assault, getting closer and closer to the bottom of the embankment. Except for a few cover groups at the end of the line, the rest basically entered the mortar firing range, and further on, the Japanese troops had to enter the mortar firing blind spot caused by the slope.

"Guards, let the mortar platoon fire."

The reason why Zhang Wei did not let the mortars open fire was because at this time, the firing of the four heavy machine guns was not of great significance to the formation of a squadron of the Japanese army, and it was limited to the embankment, the heavy machine guns could only be arranged in the rear of the infantry position, and the heavy machine guns also had shooting dead ends, but they were not as large as the shrapnel killing range of the mortars.

The Japanese troops in front were still rushing, and the guards, holding red signal flags, climbed back out of the embankment position, stood in the middle of the rear slope of the embankment, and kept waving at the mortar positions in the rear. When the mortar platoon saw the order to open fire, it immediately took out shells for rapid fire, and the firing range and blind zone had been basically determined in advance, and the gunner only needed to simply load the shells.

'Boom, boom, boom, boom'

The mortar platoon fired two rounds of rapid fire, the shells exploded within 20 to 30 meters in front of the embankment, and the shrapnel scattered in all directions, killing and injuring the Japanese troops in the attack, the Japanese troops were bombarded by mortars, and there was no time to evade, and more than 20 people were killed and wounded, and the shock formation of the follow-up team was also disrupted by the explosion of mortar shells.

"Spread out and rush towards the position!" In this case, the slower the rush, the greater the damage to the Japanese army caused by all kinds of firepower from the embankment, and the Japanese army was naturally not stupid, gritting their teeth and rushing hard.

Mortars and rifle light machine guns composed of a network of fire in front of the embankment 20 to 30 meters to inflict heavy losses on the Japanese army, the mortar platoon behind the embankment continued to open fire, shells were discharged one after another, the Japanese troops within this distance suffered heavy casualties, the Japanese troops who did not reach this distance could only grit their teeth and rush up with the belief of loyalty to the emperor, the lucky ones were not killed, and the unlucky ones could only go to see Amaterasu.

Not far in front of the Japanese army on the riverbank, the fire group covering the rear of the assault force saw that the assault troops were attacked by the fire of the preparatory battalion, in order to provide fire cover as much as possible, each light machine gun group and grenadier group began to move forward a certain distance, and the mortar can hit the assault troops in front, naturally it can be extended backwards, hit their position of covering fire, in order to avoid the rifle and machine gun fire of the preparatory battalion, while moving forward at the same time, repeatedly maneuvering, grenadier shots to change places, The light machine guns moved their positions after hitting two bridges, and although people were constantly killed by stray bullets, the casualty rate was greatly reduced.

The Japanese army's shooting and covering fire during the attack also caused a lot of casualties to the preparations, especially the point fire from grenadiers and crooked light machine guns, which were always able to accurately aim at the positions on the embankment, and now they were maneuvering, Zhang Wei did not want them to get close to the shooting corner.

To quickly get rid of them can only use artillery fire, the mortar platoon behind the set firing range is twenty or thirty meters in front of the embankment, the range has been fixed, at this time let the guards go down to inform the mortar platoon to extend the firepower is too late, there is this kung fu people have already rushed over, not to mention that once the mortar adjusts the firing range, it also needs to be test-fired, and the shooting effect is not necessarily good to deal with the repeated maneuvering Japanese cover group.

To be able to follow up the artillery fire of the moving Japanese cover group in time, I can only rely on the six grenadiers of a company.

"Tell Company Commander Qiu to transfer the grenadier groups of each squad of their company."

The first company, which was hiding in the anti-artillery hole on the rear slope, quickly pulled out six grenadier groups and climbed into the position along the rear slope, led by a company attached to He Kun.

"Battalion commander, how to fight?"

Six grenadiers entered the position, and the space in the position was suddenly much more crowded, but it was also convenient for Zhang Wei to give orders.

"Brothers, if you don't see those devil machine gun crews and grenadiers that are repeatedly maneuvering, you just want to hit them, and if the mortars can't hit well, you can only rely on you."

The six grenadier groups are lined up in a somewhat dense row in the position, the shooters and the deputy shooters calculate the approximate distance and advance from the target, and the grenadiers of the company are all the most elite veterans in the company, most of whom have experienced the battles of Nanjing and Xuzhou with Zhang Wei, and they have long been proficient in the operation of the grenadiers.

This batch of **-type grenadiers was captured by Zhang Wei from the 15th Wing of the Japanese Army near Luowang, and they were in good condition and good quality.

** The caliber of the grenadier is 50 mm, the maximum firing range is 700 meters, and the effective firing range is 500 meters, and the covering fire group of the Japanese army is completely within the effective firing range.

"Open!" As the shooter pulled the firing belt, a grenade was ejected as the first reference bullet, the grenade did not hit accurately, the grenade hit the rear of the mobile Japanese covering fire, did not cause significant damage, and the shrapnel knocked down the two riflemen in the covering fire group.

"Quick, it's ahead, fix the shot!"

Zhang Wei fired a shot at the Japanese troops, and the Japanese covering fire team was quite alert, and after the first grenade exploded, it sensed the danger and began to accelerate forward and maneuver.

All six grenadiers were loaded with grenades, and the shooting elements were adjusted according to the shooting effect just now.

"Open!"

Six grenadiers fired a salvo, and the grenades after trimming accurately smashed into the head of the Japanese covering fire group, six grenades exploded one after another, a light machine gun group and a grenadier group were directly hit on the spot, flesh and blood flew sideways, and the other cover groups were not directly hit due to dispersion and maneuvering, but the five-meter killing range of the grenade still caused them to suffer several casualties, either the machine gun shooter and the grenadier shooter were killed, or the riflemen in the group were killed by the hit.

Nine light machine guns and nine grenadiers of a squadron of Japanese troops were followed by grenadiers, and only four light machine guns and five intact grenadiers were left after being killed and wounded by the fire of the infantry machine guns prepared for crossing the river.

After the first round of fire, the grenadiers continued to fire, the second round of fire was not effective, the Japanese had already noticed, quickly maneuvered forward and dispersed, the second round of fire only knocked out one grenadier, in addition to killing and wounding some of the infantry who were assaulting.

The Japanese infantry, which was frantically advancing forward, had already rushed into the range of twenty meters in front of the embankment.
