As early as 1925, at the beginning of the establishment of the tank unit of the Japanese Army, the establishment structure of the future tank brigade was drawn up in the wartime preparation plan of the troops, according to the original idea, a tank brigade under the jurisdiction of 3 tank squadrons, each squadron under the jurisdiction of 3 squadrons, the squadron headquarters has 1 tank, 1 command tank, each squad has 5 tanks; One squadron has 17 tanks, three squadrons have a total of 51 tanks, and the brigade logistics unit also has 15 spare tanks, so the tank strength of the tank brigade is 66.

However, the above plan only existed on paper, and when the 1st Tank was reorganized into the 1st Tank Wing in August 1933, its size was significantly smaller than the wartime establishment of the 1st Tank Brigade in 1925. When the 1st Tank Wing was first established, it only had 2 tank squadrons, each squadron had 3 squadrons, the squadron headquarters had 1 Type 89 medium tank, each squad had 3 Type 89 medium tanks, and the whole wing had a total of 20 tanks, less than one-third of the 1925 preparation plan.

With the increase in tank production, by the mid-30s, the scale of the establishment of the tank wing gradually expanded and stabilized, from the war of aggression against China to the early stage of the Pacific War, the standard establishment of the Japanese Army tank wing was composed of the wing headquarters, four tank squadrons and other logistics support units. The headquarters of the wing has 1 Type 97 medium tank and 2 Type 95 light tanks; The 1st Squadron is equipped with light tanks, and has 4 tank squadrons, each of which is equipped with 3 Type 95 light tanks, plus 1 tank in the squadron headquarters, for a total of 13 light tanks; The 2nd ~ 4th squadron is equipped with medium tanks, each squadron has 3 combat vehicle squads, each squad is equipped with 3 Type 97 medium tanks, in addition to the squadron headquarters, there are 1 Type 97 medium tanks and 2 Type 95 light tanks, and the number of tanks equipped by each squadron is 12; The total number of tanks equipped with a tank wing is 52, including 31 Type 97 medium tanks and 21 Type 95 light tanks.

The support of one of the tank brigades mentioned in the telegram was two squadrons of light tanks, presumably 26 light tanks and one medium tank for the commander, according to the plan of the Chinese Dispatch Army.

As soon as the sun rose on August 4, the positions of the 70th Army on the front line of the Great Tianshan Mountains and the positions in the vicinity of Fenghuangzui and Nanchangpu were bombed by the devil's planes, and in the roaring artillery, the simple fortifications of the Chinese army were torn apart in the violent explosions, and the troops of a regiment of the Lin Weitao Brigade of the 159th Division in the area of Nanchangpu insisted in the screams, and they were bombed for two days......

In the Fenghuangzui position, the second battalion has withdrawn from the first-line position, and the first battalion and the company directly under the regimental headquarters in the second-line position are waiting for the end of the artillery fire in the reinforced fortifications, and the fortifications of the first-line position have collapsed in large numbers under the bombardment of the devil's aerial bombs, and a large amount of smoke and dust over the real mound slowly rose into the sky......

On the position of the Great Tianshan, the 70th Army, under the order of the commander, only placed a battalion of troops on the side of the devil's artillery fire to defend, and the rest of the personnel hid in the fortifications on the anticline and waited for the artillery fire to pass, anyway, they were all on a mountain, and a regiment guarding the Great Tianshan did not learn from the experience of the loss of Ma'anshan, and did not dare to put a large number of troops on the frontal battlefield, with the idea of waiting for the Japanese infantry to attack and then reinforce;

The 123rd Wing, which had built a defensive line in Ma'anshan, tasted the sweetness of a surprise attack under the cover of artillery fire in the battle of capturing Ma'anshan, and under the bombardment of the air force, it directly braved the artillery fire of its own artillery to advance the attacking troops to the forward position of departure, only 600 meters away from the defensive position of the 70th Army of the Great Tianshan Mountain, and the mountain artillery squadron of the wing headquarters was also ready......

Nanchang shop, "Hum ......"

Facing the morning glow, the roar of the motor above the head of the 159th Division was like countless flies buzzing in the ears, and the sound became louder and louder, and all the Chinese soldiers understood that this was the arrival of the devil's plane......

"Give me all the fortifications, and it is strictly forbidden to shoot into the sky!" The forward regimental commander was roaring, these soldiers who were able to survive had been beaten out of their impulsive tempers by the planes and artillery of the devils, accustomed to obeying the orders of their commanders on the battlefield, and under the orders of their commanders, at least their deaths would not be so worthless......

More than a dozen planes of the Devil Air Force showed their hideous faces from the clouds and slowly lowered their altitude towards the position of Nanchangpu.

The plane of the "Boom" devil began to drop aerial bombs, and the huge force tore all the objects around the explosion;

Last night, the brothers of the 159th Division, by order of the commander, that the fortifications that had just been built using the craters on the position were destroyed like pieces of paper under the bombardment of aerial bombs, and the position was full of huge craters......

"Ahh The soldiers who were hit by shrapnel were screaming as hard as they could, and in a battlefield where the artillery fire was so fierce, once wounded, meant death; In the midst of the explosions that are hiding in confusion, no one will come to the aid of the fallen brothers, and this will only kill in vain......

Caught in a sea of gunpowder smoke and fire, the violent explosion completely wiped out the town next to the highway, dozens of houses before the start of the war have been completely destroyed, the whole town is filled with the smell of gunsmoke, the strong air wave mixed with sharp explosives will be hiding around the soldiers like cutting wheat knock down, blood splashed out, and then a large amount of mud and sand in the air fell, sprinkled on the position into a black piece of soil, and then will be buried by new soil......

In the previous few days of continuous bombardment, the broken wall that stood firm could not be supported, and a large number of shrapnel smashed on the broken wall ...... "puff puff", and after these broken walls absorbed the last wave of shrapnel, they collapsed with a bang under the impact of the air waves, ending their mission; Many of the soldiers who were lying on the edge of the broken wall to avoid the air waves and shrapnel were buried before they could react......

Under the continuous bombardment, there was no longer a standing broken wall on the Nanchangpu position, and the roar of the devil's plane had gone away, leaving only the Nanchangpu that was razed to the ground;

A remnant veteran bent down and stood up, the floating soil on his body continued to fall with the action of standing, and as far as the eye could see, the entire Nanchang shop had been razed to the ground, and the painful moans of the wounded soldiers were faintly heard in the smoke and dust in the sky;

"Ahem, ahem...... cough cough cough ...... "A battalion commander of the forward regiment of the 159th Division drilled out of the anti-artillery hole where he was squatting, while spitting out the mud and dust in his mouth, while coughing violently, the wooden plank used to cover the smoke and dust at the entrance and exit of the anti-artillery hole was shattered by the shrenchnel of the shell, and a large amount of smoke and dust poured into the anti-artillery hole along the mouth, if the devil's plane did not leave, he would be choked to death;

The soldiers who were still alive on the battlefield were cursing, they were not afraid of death, but they were killed by the devil's shells like this, and they were a little unwilling;

"Battalion commander! Battalion commander! A bloodied officer shouted,

"What's the matter?" The battalion commander said,

"This little devil's plane is still bombed every day, and many brothers die without seeing the little devil; That's a wretch! The officer plunged the broadsword on his back into the dirt on the battlefield, venting the anger in his heart,

"Battalion commander, what is the use of saying that no matter how brave and tenacious the brothers are, how many people will die! The devil doesn't really do anything with us at all! We have already suffered heavy casualties by throwing bombs every day! This grassroots officer is venting the fear that has been accumulated in his heart by the continuous bombardment of devils in the past two days,
