Previously, when Xu Wen exchanged these tanks and armored vehicles from the system, each tank and armored vehicle, as well as the Humvee military vehicle, came with three bases of ammunition.

After so many battles, especially the first few tanks that were exchanged, the ammunition was almost exhausted.

However, the ammunition for the 20 Humvee air defense vehicles and 15 No. 4 tanks that were later exchanged was still sufficient.

Li Wu, as the commander of the tank battalion, happened to be on top of the batch of No. 4 tanks that were exchanged first, so he said that there was not enough ammunition.

In fact, the entire tank battalion, the air defense battalion, has at least twenty Humvee military vehicles and five No. 4 tanks, and the ammunition of a Sherman tank is still sufficient, and it is absolutely no problem to fight an air defense battle, which is also where Xu Wen's confidence lies.

Fortunately, the independent brigade did not fight long distances in these battles, and the fuel consumption was not high, otherwise the fuel would have been insufficient.

The 200,000 exchange points earned by defeating the 16th Division earlier have all been used up, and Xu Wen has 10,000 points left in his hand.

These 10,000 points are used just in case, and they will never be used easily until the critical moment.

Fortunately, the weapons and ammunition captured by the troops from the 16th Division are still sufficient, and with some equipment and ammunition that they have burst out from time to time, there is at least no need to worry about the ammunition of the three main infantry regiments now.

At Xu Wen's order, the tank battalion and the air defense battalion moved quickly, and 17 tanks quickly retreated from their forward positions.

Thirty Humvees were smaller, lighter, more maneuverable, and faster, so before the tanks could withdraw far, they quickly dispersed around a forward position, and in the process of shifting positions, the vehicle-mounted machine gunners also adjusted the muzzles of the anti-aircraft machine guns to the air.

After everyone took their positions, with the battalion commander Fang Shengli's order, 30 12.7 mm anti-aircraft machine guns suddenly opened fire one after another, and the eight Japanese fighters whizzing through the air fired intensively.

Originally, these eight Japanese fighters had already dived and strafed a round, but the greedy Japanese pilots relied on their superb flying skills.

After a short time of passing a low altitude from a forward position, it quickly turned around and fired wildly at the side of the Independent Brigade again, diving and strafing.

Where the dense rain of airborne bullets passed, smoke screens were formed, and some of the soldiers of the third battalion who could not escape fell in pools of blood.

However, as Fang Shengli commanded thirty anti-aircraft machine guns to turn around and fire together.

A large number of dense 12-point 7 mm caliber armor-piercing shells suddenly hit the devil fighter head-on.

At that time, the defense capability of the Japanese fighters was weaker than that of their tanks, and some of the Japanese aircraft had even wooden external armor.

This was 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 to the reason for reducing the weight of the aircraft and improving the maneuverability and endurance of air combat.

So, not to mention the special armor-piercing shells fired by anti-aircraft machine guns with a caliber of up to 127mm, even ordinary machine gun bullets can penetrate the external armor once they hit the aircraft.

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

Therefore, there will be examples in history of the squadron using light and heavy machine guns to shoot down and damage 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, and in this case, the devil's plane still dares to dive and fly at a low altitude, which is really a lantern in the toilet and kills itself.

Bang bang! As a large number of hot anti-aircraft machine guns rained down armor-piercing bullets one after another, the defensive armor of the four Japanese Type 97 fighters at the head was pierced one after another, and two of the pilots were killed on the spot.

Originally, on the Japanese position, a large number of devils were watching a good show, expecting their own air force to wipe out all the squadrons.

However, unexpectedly, before the air raid and bombing began, two of our own fighters lost control and collided directly with their own positions.

Frightened, the devil soldiers on the ground cried wolf-like howls, and scattered in all directions in a panic.

But the two planes were so fast that they fell almost simultaneously before the Japanese troops in the attacking position could disperse.

Boom boom! Two violent explosions suddenly sounded on the Japanese offensive position, and two dazzling red lights and thick smoke were entangled with each other and hovered to the ground.

In the explosion, at least hundreds of devil infantry were blown up on the spot because they couldn't dodge, and they couldn't die anymore.

And the anti-aircraft strafing on the side of the independent brigade continued, and the other two Type 97 fighters that were hit, one of the wings was broken by dense anti-aircraft fire, and one of the fuel tanks was hit and caught on fire.

After the two planes flew over the air defense positions of the independent brigade, they also quickly lost control, and they were less than 100 meters above the ground at that time, so it was impossible for the devil pilots to parachute.

Therefore, the two Type 97 fighters dragged thick black smoke, and under the gaze of countless Japanese soldiers on the ground, they finally crashed into the mountains and forests in the distance and disappeared.

Four of the eight fighters were killed in the blink of an eye, and the four Japanese fighters who were lucky not to be hit by the anti-aircraft fire of the independent brigade were so frightened that they hurriedly turned around and fled.

At this time, more than 20 Japanese bombers finally flew over the position south of the city of the Independent Brigade and began to bomb them.

Heavy bombs fell off from the magazines under the belly of the bomber, and smashed down to the ground in free fall with a piercing scream.

you! 俅俅俅俅......

The whistling sound of the falling bomb makes people's scalp tingle.

At this time, Xu Wen had already led all the tanks, withdrew from the forward position of the first regiment, and transferred to the vicinity of the south gate near the headquarters of the first regiment.

Seeing this, he immediately ordered all the Humvee military vehicles: "Mobilize for me, don't stay where you are!" ”

Just kidding, the large-scale bombing of more than 20 bombers, not to mention the Humvee military vehicles with weak defense capabilities, even the Tiger and No. 4 tanks under their own command did not dare to stay still and be bombed.

Although the accuracy and density of the maneuvering anti-aircraft shooting may be affected, the survival rate is greatly improved!

The bombers of this year were not as powerful as those of later generations, and the bombs were dropped by the eyes of the crews and their approximate measurements, and the bombs were dropped wherever they landed, and it was impossible to track the change of lanes.

Therefore, as long as the combat vehicles of the air defense battalion on the ground are fast enough and quickly dodge the area that is intensively bombed by devils, there will be no catastrophe.

Only by surviving first can you have a chance to hit the devil bomber hard!

After receiving Xu Wen's order, Fang Shengli immediately ordered all Humvee military vehicles to quickly maneuver to dodge.

The air defense fighters also sensed the danger, and drove their military vehicles at full speed to frantically flee in the east and west directions of the position, and finally fled the most dangerous area of the forward position before the devil's aerial bomb fell and exploded.
