The real division strike support blockade firepower should be a heavy howitzer with a caliber of 155 mm. In combat integration and city fortress battles, it is necessary to have a killer such as the m115 type 203 mm caliber heavy howitzer or the b4 heavy howitzer can work.

The artillery was not coming, so Gao Fei had to make a big fuss about Tom's ammunition. The absolute killing radius of a heavy howitzer with a caliber of about 15 mm is about fifteen meters. Within this range, even if there is no shrapnel hit directly, such as hiding in a trenches, he will die from shock waves, infrasonic waves and fragmented killing radius. Then within a range of fifty meters, at least three shrapnels will fall down per square meter to ensure the level of killing. Only if it exceeds 200 meters and lying down in time can it be possible to survive death or injury. Generally, the absolute safe killing radius of a heavy howitzer with a caliber of above 150 mm is about 200 meters.

At this moment, the various ammunition fired by Tom, who bombarded the Japanese army, were specially made by the United States according to Gao Fei's requirements. Tom is the main model currently produced and equipped by the US military. It is equipped with a series of complete ammunition systems, including concrete penetration bullets and special tail stable shells. The warheads of the special tail stable shells are made of chromium vanadium alloy and have a length of about 70 cm. Because the material density of the bullet body and the warhead is very high, so

It can increase the penetration force of the warhead. The shell projectile is equipped with a thick shell shell and can withstand the impact force it is subjected to through. The rear end of the shell is equipped with six steel wings and is wrapped with a special outer cylinder. When the shell rushes out of the muzzle, the outer cylinder will automatically fall off. The six wings will automatically jump away by the action of the spring mechanism to ensure that the ballistics can be maintained stable. The warhead can penetrate up to two and a half meters thick reinforced concrete fortifications according to the principle of inertia concentration, but this is only theoretical data.

The Japanese, who were poor, short, thin and long hair, naturally did not have that luxury to build two and a half meters of concrete thick walls, so the special tail-stabilized shell fired by Tom from M2 long feet was truly invincible. In order to speed up the firing speed, the gun adopts a three-stage split-type firing method, twice the artillery operator, and the projectile and medicine bag are separated in advance. A small crane is installed on the left side of the gun stand to transport ammunition and speed up the firing speed.

The third total attack of the Chinese army on Wuhan began at dawn on July 19, 1942. After one morning of bombing and artillery preparations, Niuwan Town, Xitang Village, Mengwan Town and Sanjie Mountain within the defense of the 16th Division of the Japanese Army were almost razed to the ground. The communication between the 16th Division and the military headquarters under the command of Shiro Makino was interrupted, and there were no signs of troops breaking through. Shiro Makino himself was uncertain about his life and death, and the communication between the four infantry regiments under his command was also interrupted. Anan Wei was a commander with extremely rich battlefield experience. He knew that at least one-quarter of the officers and soldiers would survive the brutal fortification defense system. This is an ironclad fact. The blood sacrifice of the mountains and rivers of the Anti-Japanese Rivers 737

The biggest killing of the officers and soldiers of the 16th Division was not the shelling that seemed to collapse, but the American napalm bomb that fell from the sky. A heavy napalm bomb could sweep the cut within 500 square meters, which could drain all the air within a few hundred meters, heat the air to hundreds of degrees, so that the breathing person would burn the respiratory tract and suffocate.

The Americans actually handed over such cruel weapons to the Chinese army on a large scale. The artillery fire that day and earth cracked made Anan Wei frightened. Once upon a time, these were the patents of the Imperial Japanese Imperial Army. The Chinese were trembling under simple fortifications. Now it proved the old Chinese saying that in thirty years, Hedong and Hexi, Anan Wei was not afraid of the fierce artillery fire of the Chinese Youth Army, because he firmly believed that the invincible spirit of the Imperial Japanese Imperial Army would overcome all difficulties and defeat all enemies.

What Anan Weiji was afraid of as a general was that Gao Fei's huge ammunition consumption was behind Gao Fei's huge ammunition consumption, which was equivalent to a battle ammunition prepared by the entire 11th Army! In just one morning, those thousand-pound bombs and napalm bombs swept through the defense zone of the 16th Division. The Americans behind Gao Fei had many huge war resources? How could they transport so much ammunition from afar and make the Chinese army so luxuriously consume?

After today's shelling, Anan Weiji didn't know that the artillery shell could be launched so luxuriously, and used steel to create a breakthrough in the enemy's dense and solid fortification system. In just one morning on July 19, 1942, Gao Fei used a mechanized division to match three infantry divisions to clear the remaining enemies of the Japanese 16th Division in Niuwan Town, Xitang Village, and Mengwan Town to stabilize the breakthrough. The mechanized division re-aligned the battalion and company units to prepare for street fighting. Gao Fei reminded the clearing troops to move rapidly and may have unexpected gains.

All the commanders understood what the unexpected gain of Gao Feizhi was. In Nanchang, a sudden storm-like artillery bombardment was lucky enough to seize the 23rd Japanese Infantry Flag. This artillery and bombing were even more violent. Perhaps a Japanese gang flag could be seized. Since the Battle of Nanchang, the Japanese army has improved the system of preservation of the gang flag. The infantry gang that carried out tasks of the isolated army or upright behind the enemy should temporarily be incorporated into the division or brigade headquarters headquarters. After the battle was completed, it can be built. The Japanese really couldn't afford to lose the infantry gang flag. In the battle of Nanchang, the Japanese lost a gang flag. In addition to Okamura Yanji, there was no big trouble, more than a dozen colonels and generals had a paternal saccharisma and apologized. All the surviving officers and soldiers of the department were forced to commit suicide.

The iron triangle that Niuwan Town, Xitang Village, and Mengwan Town rely on each other was smashed and ruined. The broken corpses and internal organs of the Japanese army were everywhere. The soft soil feet could sink into it as soon as they stepped on it. A handful of soil would have shrapnel. When they squeezed hard, the water flowed out was covered with fishy, ​​dark red liquid.
