Even if I'm a useless bum at Whampoa Military Academy, I'll be invincible in the War of Re

The Yokoyama Battalion had been decimated before, and the guerrilla detachment was the main culprit. They had been replenished several times, and when they first landed, almost all of the Japanese soldiers were dead, including two "hundred-man killers".

The fighting spirit of the replacement soldiers was clearly not as high as that of the original troops. After being bombarded by the isolated battalion for several rounds, the army formation became quite chaotic. Some turned to flee and were cleaved in two by Major Yokoyama's sword.

"You idiot, coward, die!"

Major Yokoyama resembled a mad dog in a berserk state, and Naoto Nakayama stopped his escape and gritted his teeth to continue charging forward.

His team suffered one death and one injury, leaving two members. They had no choice but to temporarily form a formation with other teams and cooperate with each other to advance.

Bullets were flying everywhere, and whether one could survive depended entirely on luck. Naoto Nakayama charged forward and fired as he went, not caring whether he hit anyone or not, at least it gave him courage.

As the engagement distance closed, the defenders' hit rate improved significantly. Private Zhongshan was constantly being shot and falling around him, and the cries of pain terrified him, making his legs tremble uncontrollably.

Naoto Nakayama dawdled, and the sergeant behind him kicked him to the ground. A hot bullet almost grazed his scalp and hit the sergeant.

"Little Hubei" accidentally killed a Japanese soldier and was so excited that he danced around. Yang Guai grabbed him and pulled him into a trench, where he luckily dodged a bullet.

"You little brat, you want to die?!"

Yang Guai's roar made Xiao Hubei realize that he had become a bit too complacent. After Battalion Commander Yang's condition improved, he also returned to his combat unit.

After being yelled at by Platoon Leader Shi, Xiao Hubei became noticeably more alert and cautiously poked his head out of the trench.

At this time, everyone was fighting and no one had time to take care of him. Soon he spotted a sneaky-looking Japanese soldier, who was none other than Naoto Nakayama.

Xiao Hubei cautiously aimed his gun at Naoto Nakayama, afraid of startling the Japanese soldiers. Despite his young age, he had seen his share of battles at the Sihang Warehouse and was not afraid of the Japanese at all.

Naoto Nakayama fired a few shots haphazardly, and a bullet whizzed past, almost grazing his helmet. This kid's life is really tough.

Little Hubei is a stubborn guy. He's got a grudge against Naoto Nakayama and he's determined to kill that bastard!

Xiao Hubei gently pulled the bolt to chamber a bullet. He was using a Springfield M1903 rifle, 7.62 mm in caliber, which was more accurate than the short-barreled Mauser and better suited for long-range shooting.

The 7.62mm bullet used by the Springfield rifle is compatible with the bullets used by the M1919 medium machine gun and M1918 automatic rifle, which are widely used by the guerrilla detachment, greatly reducing the pressure of supply.

As the number of troops increased, the sniper rifles were changed to Springfield rifles and equipped with 4x scopes. Only the MP38 submachine gun used 9mm pistol ammunition.

Zhao Yunwen is considering replacing the MP38 submachine guns with the M1 Garand semi-automatic rifle, with four rifles per squad, which should provide sufficient firepower.

Compared to the short-barreled Mauser, Xiao Hubei prefers the Springfield rifle, which has less recoil and higher accuracy. After all, he is only 13 years old and his small body cannot withstand too much recoil.

The battlefield was teeming with Japanese soldiers, but Xiao Hubei clashed with Naoto Nakayama. Naoto Nakayama seemed to have discovered Xiao Hubei's intentions, and was so angry that he fired two shots at Xiao Hubei.

Xiao Hubei was somewhat annoyed. He only had one bullet left in his magazine. Although the guerrilla detachment had an open supply of bullets, he still felt bad about it.

He aimed his gun at Naoto Nakayama again, held his breath, and patiently waited for his opportunity.

The offensive of the Yokoyama Battalion has been suppressed by the isolated battalion. The two sides are now competing in marksmanship at a distance of about a hundred meters, which is a battle of inner strength.

The Japanese infantry were known for their accurate marksmanship, but this time they encountered an isolated battalion from the 88th Division, equipped with a large number of sniper rifles and suppressed by heavy firepower. The tactics that the Japanese were so proud of were no longer effective.

The Type 3 machine gun could only fire a few bursts before being destroyed by M2 mortar shells. The three M2 mortars that were the first-level equipment of the guerrilla detachment became a nightmare for the Japanese machine guns and grenade launchers.

This is Zhao Yunwen's complete replication of the US military's World War II-era first-level firepower configuration. Each gun crew consists of 5 people: a crew leader, a gunner, two assistant gunners, and one ammunition handler. It can effectively suppress weapons such as the Type 92 heavy machine gun, the Type 11 light machine gun, and grenade launchers within a range of 400 to 1200 meters. It has a maximum range of 1870 meters, a high rate of fire, high accuracy, high lethality, and high mobility. It was not replaced until after the Vietnam War.

With the M2 suppressing them, the guerrilla detachment's infantry company easily overwhelmed the Japanese infantry company, and the isolated battalion could easily take on Yokoyama's battalion one-on-one, which was unacceptable to Major Yokoyama.

In his mind, the opponent of the Yokoyama Brigade must be at least a regiment, or even a division, of the Chinese army!

"You idiots! A bunch of useless trash! You've completely disgraced the Imperial Army!"

Major Yokoyama brandished his sword, driving the Japanese soldiers forward. Naoto Nakayama could only climb out of the shell craters and continue his advance.

Xiao Hubei had been waiting for this opportunity. He decisively opened fire, hitting Naoto Nakayama in the abdomen. The Japanese soldier struggled on the ground for a few moments in pain before falling silent.

A volley of M2 high-explosive shells landed on the Japanese troops. The three shells almost covered an entire infantry squad, taking down seven or eight soldiers. Major Yokoyama's face turned frosty at the sight.

He was powerless against the mortars of the isolated battalion; the number of infantry guns was too small, and the performance of the grenade launchers was completely suppressed, making them impossible to reach.

The combination of the M1919 medium machine gun and the M2 mortar in the isolated battalion gave them a significant advantage in medium- and long-range engagements. The Japanese infantry tactics that they were so proud of were completely suppressed, and any massed charges were tantamount to suicide missions.

The entire battalion unleashed its full firepower with four 20mm mortars and nine M2 mortars, raining down shells in volleys. Combined with the strafing of dozens of light and heavy machine guns, the Japanese soldiers were felled in droves. In a short time, the ground was covered with corpses and wounded, numbering at least two hundred.

"Baka! No!"

"Quickly, retreat!"

Major Yokoyama was finally awakened. The human wave tactic was ineffective against the guerrilla brigade; it was no different from sending them to their deaths. If the fighting continued, he would become a brigade commander without any troops.

The bugle call to retreat came from the rear. The remaining Japanese soldiers of the Yokoyama Battalion felt as if they had been granted a pardon and hurriedly retreated back to their starting position, not even bothering to take the seriously wounded with them.

Similar to the right wing, the large battalion on the left wing was also driven back, leaving only the 20th Infantry Regiment in the center to hold out.

Although the central river valley plain is advantageous for offense, the Ohno United team is still unable to fully unleash their potential and has no way to exert their strength.

The tank squadron was too scared to go into battle, the regimental artillery had to change positions after firing a few rounds, and the heavy machine guns dared not show their faces, which was very frustrating.

Without the support of heavy firepower, the Japanese troops' ability to attack fortified positions was greatly reduced, and the river valley plains became a place of sorrow for the Ōno Regiment, littered with corpses lying in disarray.

The First and Second Battalions relied on earth and wood fortifications hundreds of meters deep, along with a large number of landmines and trenches to block the enemy. Every step the Japanese took forward required a bloody price, and the anti-tank trenches were almost filled with corpses.

After retreating on both flanks, the Ōno Regiment held out for another half hour before finally slinking away in disgrace.

Despite their best efforts, the 19th Infantry Brigade was unable to break through the guerrilla detachment's position. Both main regiments suffered more than half their casualties, and the artillery regiment lost as much as 70% of its artillery and nearly half of its tanks. Major General Cao Chen had no choice but to request reinforcements from the division headquarters.

Upon receiving the telegram requesting assistance from the 19th Brigade headquarters, Nakajima Kesago immediately broke down in anger, shouting:

"Useless, a bunch of useless trash!"

"An infantry brigade couldn't defeat a small guerrilla unit; the Imperial Army has completely lost face."

"Nakazawa-kun, how should we deal with this?"
