To say that the combat effectiveness of the Japanese army is really very tenacious, under such a fierce offensive, the surviving tanks risked being destroyed at any time, and the machine guns on the tower also roared wildly, and it was very effective, in a short time, two helicopters crashed under their frantic strafing.

Although the 7.7 mm bullet could not penetrate the thick armor of the helicopter, it was more than enough to hit the windshield on the front, and even if the driver inside wore body armor, it could not stop the 7.7 mm heavy machine gun bullet.

The crash of the two helicopters seemed to have given the Japanese a lot of confidence, and the machine gun fire became even more frenzied, and there were even many light machine gunners who picked up their light machine guns and jumped out of the trenches directly, howling and firing wildly into the sky.

On the opposite valley, Jiang Haoran led a group of generals to stand in the wind, located in a high position, and the entire battlefield was in full view.

Behind him is a well-groomed flat field, a row of tables and chairs are lined up on the ridge, and on each chair sits a telegraph soldier wearing a headset, each telegraph soldier has a high-power walkie-talkie in front of him, each walkie-talkie controls a tank and a helicopter, Zhuang Yingying is also impressively listed, but the walkie-talkie in front of her controls all the planes over the entire battlefield, so Mei Xiang and Mei Xin have become her assistants.

In front of every 10 telegraph troops, there will be an operational staff officer in front of the command, so the entire battlefield of more than 80 helicopters and more than 80 tanks is naturally divided into eight squadrons, each squad has a combat area, and the combat staff officers promptly adjust the direction of attack of the tanks and helicopters according to the battlefield situation. If the forward attacking force finds the enemy's heavy fire point, which is flawless or cannot be destroyed on its own, the helicopter or tank walkie-talkie will immediately notify the rear, and the combat staff will deploy the nearest tank or helicopter to assist.

When there is a gap on the battlefield, for example, when two helicopters crash on the battlefield just now, the combat staff will immediately mobilize nearby helicopters and tanks to concentrate their firepower to destroy the enemy's firepower points, and then use the distance to ensure the continuity of firepower, so that the entire defense line is under attack and surveillance.

Although it was night, the artillery fire had already burned the entire sky over Meng Gong red, and the sight was similar to that of daytime, and it was even better to observe the enemy's heavy fire points than during the day, and the flames of the guns were more obvious at night, and they could not escape the eyes of the combat staff at all.

On the battlefield, over the Menggong Heights, helicopters attacked from the left, right, and frontal directions, with heavy machine guns and machine guns volleying in the air, and rockets and missiles pouring down like rain.

On the slope of the hill on the ground, more than 80 tanks advanced in a trapezoidal shape, and they were only one or two hundred meters away from the front line, and the battle defense guns at the front suddenly spat out tongues of fire.

The tank echelon formation is a formation adopted when attacking a position with a large defensive depth, with the purpose of increasing the impact of the attack and maintaining the continuity of the attack. The echelon formation is divided into two echelon formations, three echelon formations, and even four or more echelon formations can be organized according to the enemy situation and the battlefield terrain. The biggest weakness of the echelon formation is that it is not convenient to maintain the flexibility of the formation to "turn to attack".

Jiang Haoran is using three echelon formations at the moment, which is used to concentrate firepower while effectively covering the infantry, forming an iron wall in front of the infantry.

Under the dense network of ammunition of the expeditionary force, the heavy fire on the enemy's defensive line gradually decreased, and several artillery positions were destroyed by helicopters and tanks before they could exert their power.

At this moment, Jiang Haoran raised his right hand high and howled: "T change formation, line attack!" ”

As soon as the voice fell, the combat staff officers behind him began to roar hoarsely, "T change formation, line attack!" ”

Subsequently, the telegraph man behind the combat staff officer also began to call his own tanks and send orders to each tank.

"T" stands for tank, in order to facilitate command, not easy to confuse commands, in the operation, Jiang Haoran helicopter, tank, airplane are all replaced by letters, helicopter is "H", airplane is "F", simple and clear.

The tank line formation, that is, the "one-line flat pendulum" battle formation, is also known as the horizontal formation. Generally, it is used when the enemy situation is clear and the terrain is open, which is convenient for armored troops to impact at high speeds. Of all formations, the line formation is the one that maximizes the tank's firepower. Usually, the line formation is also a charging formation, and the hand-to-hand contact is in the next second.

The order was given, and the tanks on the hillside were quickly interspersed with diversions, and the trapezoidal formation just now immediately turned into a linear swing, and the infantry behind the tanks also began to diverge, looking from afar, a thick black line was formed behind the tank, rolling forward with the advance of the tank.

Helicopters began to drop smoke bombs on the ground, and the colors of the smoke bombs were divided into several types, each color was represented, red represented by the threat was not completely cleared, and the ground may be hidden with uncertain firepower or troops, and the attacking troops must be paid attention to when entering. Purple is secondary, while blue is basic security.

At this time, the helicopters have basically finished pouring ammunition, most of them have begun to return to reload, a small number of helicopters in the air as patrols, fixed-point pull-out of heavy firepower that has not been destroyed, but also to prevent the enemy from taking the opportunity to escape, with their aerial surveillance, if the enemy wants to retreat in formation, it is tantamount to looking for death, no one can run faster than the helicopter, nor can it run faster than the bullet.

In fact, at this time, the enemy's combat effectiveness has been basically paralyzed, and the helicopters are already vacating the battlefield for the tanks and infantry behind.

As the tanks rushed up to the Menggong Heights, the black-pressed infantry also screamed and surged up, and the sound of AK47 began to roar for a long time.

Just when the artillery fire above Menggong continued, more than ten miles away from the Menggong Heights, there was a small forest, where the Japanese 55th Division was encamped, and the division commander Tada Jun immediately ordered the troops to set off after receiving a request for reinforcements from Nakajima Imasago Imasato.

As soon as the troops came out of the woods, they were immediately detected by reconnaissance planes of the expeditionary force in the sky, and then countless planes came one after another, and in an instant, aerial bombs rained down, and then machine guns and machine guns repeatedly dived and strafed, wiping out this area and the entire forest on the ground.

Although the sight at night is not good, the entire Menggong front is a vast open field, there are only a few small woods like this, if the enemy does not move, they really don't know where the Japanese army will hide, but as long as their figure appears in the unobstructed yellow earth, it is difficult not to be spotted by the planes in the air.
