The expeditionary force began to dominate Southeast Asia by recruiting defeated soldiers

There were more than 20 soldiers missing from the team, and they took the defeated soldiers back first.

Zhang Chi sat in the co-pilot seat of the M15 self-propelled anti-aircraft gun and led the rest of the team forward. He was not satisfied with the 400 people he had just rescued. He wanted to recruit more defeated soldiers and save the lives of more compatriots.

The failure of the first Burma Campaign swept across the entire expeditionary force like a tide. The retreat became extremely chaotic and the soldiers dispersed on the long journey home.

Some were unable to resist the Japanese pursuit and were broken up into small teams; some were trapped in the primeval forests of Myanmar, struggling with hunger, disease and cruel environment; only a few who were particularly lucky managed to return to Yunnan Province.

Zhang Chi thought that if he could recruit these defeated soldiers on the road, it would undoubtedly save them from suffering and give them another chance to take up arms and fight for their country.

Thinking of this, he suddenly found that his actions had a sense of mission.

Just as he was lost in thought, a hurried voice came from the radio.

"Calling the nest, we've encountered a Japanese ambush." ​​Xiao Dongbei's voice came over the radio, a little nervous. "The Japanese have now mastered the tree-hiding tactics you taught us. Their main force has blocked the mountain road, and scattered Japanese are ambushing in the trees beside the road, shooting down our retreating comrades. What should we do? Should we take them down?"

Zhang Chi was delighted to hear this. The tree climbing technique he'd taught was actually something he'd learned from a later TV series about the Expeditionary Force, depicting a common Japanese tactic used in jungle warfare. Now, he'd never expected it to backfire, creating a true "father resembles son" situation, which struck him as a bit absurd.

He fell into deep thought. Ambush and counter-ambush operations in the jungle were extremely complicated. The Japanese snipers took advantage of the dense forest and terrain and were not easily discovered.

The extreme development of this jungle concealment tactic is the situation encountered by the Bald Eagle soldiers where "the forest speaks Annamite."

For this set of tactics, a certain northern power also gave a standard answer - firepower coverage.

"Listen to my command later. Have your team's light machine guns use tracer bullets to sweep the area where the Japanese may be ambushing, targeting the large trees where they are hiding. Don't focus on accuracy, just get a rough idea of ​​their location first. After shooting, take cover immediately and don't expose yourself."

While giving orders, Zhang Chi asked Qi Quan and Bai Minghui to lead the infantry troops to prepare for battle.

Then he directed the M15 self-propelled anti-aircraft gun to turn around and point the rear of the vehicle at the distant jungle. Without the obstruction of the front of the vehicle, the anti-aircraft gun turret in the rear cargo bed could maximize the shooting angle. He then got out of the vehicle and raised the telescope, carefully observing the lush rainforest on the distant mountain.

Fearing that the shelling might accidentally injure the little Northeast on the mountain, he did not plan to use the 90mm mortars carried on the Bedford trucks, but only prepared to let the newly purchased M15 self-propelled anti-aircraft guns fire.

"Calling the White Owl Squadron, we can mark the location of the Japanese ambush."

As the order was given, the light machine gun fired a burst of "tatatat" sounds, and the tracer bullet drew a green light, accurately pointing to the treetops where the devils were hiding.

Zhang Chi immediately shouted the order: "Fire!"

M15自行防空炮搭载的37mm M1A2高射炮开火了，这门理论射速高达每分钟120发的速射机炮喷吐着火舌，将一发又一发高爆破片燃烧曳光弹射向了远处的绿色森林。

The other two 12.7mm M2HB heavy machine guns in the turret also fired, fiercely strafing the area where the Japanese were hiding, and the bullets in the ammunition belt, as thick as fingers, were consumed rapidly.

Flak leveled, court martial.

Zhang Chi had no intention of playing hide-and-seek with the Japanese hiding in the rainforest. The doctrine of "firepower advantage" was all about coverage.

The 37mm shells, each as thick as a woman's forearm, fired at a high rate of fire, turning them into jungle destroyers. Countless tall rainforest trees fell like they were struck by a chainsaw. However, before these trees fell, the Japanese soldiers hiding in the treetops had already been killed by the flying fragments of the exploding shells.

The barrel of the M1A2 anti-aircraft gun began to turn visibly red during continuous firing, and the gunner had to reduce the rate of fire to prevent the barrel from overheating and exploding.

The remaining Japanese ambush troops had no time to pursue the defeated Kuomintang soldiers in the mountains. They quickly adjusted their formation and rushed towards Zhang Chi, trying to destroy the M15 self-propelled anti-aircraft gun.

It was because the flat anti-aircraft gun was so terrifying that any Japanese soldier whose body was directly hit by the 37mm HEFI-T was directly turned into a puff of blood mist. They didn't even need to be cremated and could be directly put into boxes and buried.

The bullets from Yousaka's rifle flew towards him with a whizzing sound, and Zhang Chi, who was outside the car, took a quick step and hid in the nearby bushes.

There was no choice but to hide. The driver of this M15 self-propelled anti-aircraft gun had a steel plate in front of him with several slits on it for him to observe the road conditions. The turret at the rear of the vehicle was surrounded by vertical steel plates, and there was a thick gun shield in front of the gunner and loader.

Only Zhang Chi, who was outside the car, had nothing but a mortal body, so he could only hide.

At the same time, the reconnaissance squad of Xiao Dongbei in front opened fire. They happened to be on the flank of the charging Japanese troops. The continuous firing of submachine guns and thrown grenades quickly interrupted the Japanese troops' wave-like charge.

The two 12.7mm M2HB heavy machine guns showed their power at this time. When facing the charging formation of the Japanese infantry, this large-caliber machine gun returned to the essence of the machine gun invented by the doctor named Gatling - to harvest lives as quickly as possible in order to end the war and avoid more deaths.

One after another, the Japanese were knocked to the ground by the M2HB heavy machine gun. Even because of the narrow mountain road, the Japanese charging formation was very dense. Sometimes a 12.7mm bullet could penetrate the body of the next Japanese soldier without losing its power after penetrating the previous one.

"Make a detour! Make a detour!" A Japanese second lieutenant saw that he could not rush forward head-on, so he quickly waved his saber and ordered the remaining soldiers to make a detour through the rainforest on both sides of the mountain road, trying to bypass the front line of defense.

However, when the Japanese rushed into the rainforest, they ran into the second and third companies that had come to encircle them.

Zhang Chi equipped his independent battalion's company commanders, squad leaders, and non-commissioned officers with M3 submachine guns and M1A1 carbines. These weapons capable of continuous fire were much more useful in close combat in the jungle than the Type 99 rifles with bayonets in the hands of the Japanese infantry.

The Japanese suffered a heavy loss at the first encounter and were overwhelmed by the large number of bullets coming towards them.

Qi Quan led the squad leaders to clear the way in front of the team with submachine guns and Bren light machine guns, driving the Japanese who tried to enter the rainforest back to the mountain road.

The Japanese soldiers who returned to the mountain road continued to be covered by 37mm anti-aircraft guns and M2HB heavy machine guns, with almost no room to fight back. Suppressed by the fierce firepower of the independent battalion, they could only lie on the ground and wait for death.

The gunshots continued to ring out, and the Japanese fell one after another in the dense rain of bullets. The battle came to an end, and their bodies were scattered in the jungle and mountain roads.
