When Xu Wen exchanged these tanks and armored vehicles from the system, each tank, armored vehicle, and Hummer military vehicle brought three base ammunition.

After several battles consumed, especially the tanks that were first exchanged, the ammunition was almost exhausted.

However, the twenty Hummer air defense military vehicles and fifteen No. 4 tanks that were exchanged later were still sufficient ammunition.

As the battalion commander of the tank battalion, Li Wu happened to be on the first batch of No. 4 tanks that were exchanged out, so he said that he lacked ammunition.

In fact, the entire tank battalion and air defense battalion have at least twenty Hummer military vehicles and five No. 4 tanks. One Sherman tank has sufficient ammunition, so it is absolutely fine to fight an air defense battle. This is also Xu Wen's confidence.

Fortunately, the Independent Brigade did not have long-distance marching operations in these battles, and the fuel consumption was not high, otherwise the fuel would be insufficient.

The 200,000 redemption points earned from defeating the 16th Division have been used up, and Xu Wen has only 10,000 points left.

These ten thousand points are used just in case, and will never be used easily until the critical moment.

Fortunately, the troops seized sufficient weapons and ammunition from the 16th Division, and they occasionally exploded some equipment and ammunition, so now they don’t have to worry about the ammunition of the three main infantry regiments.

With Xu Wen's order, the Tank Battalion and the Air Defense Battalion moved quickly, and seventeen tanks quickly retreated from their frontier positions.

Thirty Hummer military vehicles were small in size, light in weight, stronger maneuverability and faster speeds, so before the tanks could withdraw, they quickly spread around a regiment of frontier positions. At the same time, while the on-site machine gunners also adjusted the muzzle of the anti-aircraft machine gun to the air while moving their positions.

After each took his place, with the order of the battalion commander Fang Shengli, thirty 12.7 mm anti-aircraft machine guns suddenly opened fire and intensively shot towards the eight Japanese fighters whizzing through the air.

Originally, these eight Japanese fighter jets had dived and strafed for a round, but the greedy Japanese pilots relied on their superb flight skills.

After passing by a low altitude from a regiment of frontier positions, he quickly turned around and fired wildly at the Independent Brigade, diving and storming.

Wherever the dense rain of airborne bombs passed, smoke screens formed, and some soldiers from the Third Battalion who could not escape fell into a pool of blood.

However, as Fang Shengli directed 30 anti-aircraft machine guns to turn the direction, they opened fire and fired together.

A large number of dense 12-point 7 mm caliber armor-piercing bombs suddenly rushed towards the Japanese fighter.

At that time, the defense capabilities of Japanese fighters were weaker than their tanks, and some Japanese aircraft had external armor or even wood.

This is mainly related to the fact that Japan was an island country at that time, and strategic resources such as steel and oil were all imported. In addition, there are reasons for reducing the weight of the aircraft, improving air combat maneuverability and endurance.

So, let alone the special armor-piercing bullets fired by anti-aircraft machine guns with a caliber of up to 12.7mm, even ordinary machine gun bullets can penetrate their external armor once they hit the plane.

Once the hit position is a key position such as the fuel tank or engine compartment, the plane will inevitably crash.

Therefore, there have been cases in history where the Chinese army used light and heavy machine guns to shoot down and injure Japanese aircraft, but this requires a specific environment and very high luck.

But now, the air defense battalion of the Independent Brigade has absolutely strong strength. In this case, the Japanese planes dare to dive at low altitude, which is really a lantern in the toilet and seeking death.

Bang bang bang bang bang! As a large number of hot anti-aircraft machine gun armor-piercing bullets hit one after another, the defensive armor of the four Japanese Type 97 fighters that led to the attack were penetrated one after another, two of the pilots were killed on the spot, the plane lost control, and flew over the frontier positions of the Independent Brigade with the help of inertia, and fell down fiercely according to the Japanese offensive positions in front.

Originally, a large number of Japanese devils were watching the show on the Japanese position, hoping that their air force could destroy all the Chinese army.

But unexpectedly, before the air raid bombing began, two of its own fighter jets lost control and crashed straight into their positions.

The Japanese soldiers on the ground were so scared that they screamed like ghosts and howls, and fled in panic.

However, the two planes were very fast. Before the Japanese troops on the offensive positions fled and scattered, they fell almost at the same time.

Boom! Two violent explosions suddenly sounded on the Japanese offensive position, and two dazzling red lights and thick smoke entangled and hovered and rose up.

During the explosion, at least hundreds of Japanese infantry were blown away on the spot because they could not hide, and they could not die again.

The air defense strafing of the Independent Brigade continued. One of the other two hit Type 97 fighters was interrupted by dense air defense firepower, and one fuel tank was hit and caught fire and burned.

After flying over the air defense position of the Independent Brigade, the two planes quickly lost control. They were less than 100 meters away from the ground at that time, and the Japanese pilots could not parachute.

So the two Type 97 fighters dragged thick black smoke and, under the gaze of countless Japanese troops on the ground, eventually crashed into the distant mountains and forests and turned into nothing.

Four of the eight fighter jets were killed in a blink of an eye. In addition, four Japanese fighters who were lucky enough not to be hit by the air defense firepower of the independent brigade were so scared that they turned around and pulled up and fled.

At this time, more than 20 Japanese bombers finally flew over the southern position of Independence City and began bombing.

The heavy bombs fell off the bullet casing under the belly of the bomber aircraft, and with a harsh whistle and thunderous sound, hitting the ground hard.

Affair! Affair...

The howling sound of the bomb falling makes the scalp numb.

At this time, Xu Wen had led all the tanks to withdraw from the frontier positions of the first regiment and moved to the south gate near the command center of the first regiment.

Seeing this, he immediately ordered all Hummer military vehicles: "Move them all, don't stay where they are!"

Just kidding, the large-scale bombing of more than 20 bombers, let alone Hummer military vehicles with weak defense capabilities, even the Tiger and No. 4 tanks under his command would not dare to stay in place and be bombed.

Although the accuracy and density of firepower of air shooting when maneuvered may have some impact, the survival rate will be greatly improved!

The bombers in the past are not as powerful as those in later generations. The bombs are all measured by the eyes and roughly. Wherever the bombs land, they cannot be tracked and changed lanes.

Therefore, as long as the air defense battalion tanks on the ground are fast enough to quickly avoid the area that was bombed by the Japanese, there will be no catastrophe.

Only by surviving first can you have the chance to severely damage the Japanese bomber!

After receiving Xu Wen's order, Fang Shengli immediately ordered all Hummer military vehicles to quickly avoid.

The air defense soldiers also noticed the danger and drove their military vehicles to flee wildly in the east and west directions of the position. Finally, before the Japanese aviation bomb fell and exploded, they fled from the most dangerous area of ​​the frontier position.
Chapter completed!
