The drill of the tank is similar to that of the armored vehicle, but there are some more test items, such as the tank to shell in the middle of the road, when it stops, it is used as a fixed battery to shell forward, left, right, etc., and the pillbox is shelled to test the destructive ability of the artillery.

The tank was still in practice, Cai Guodong turned his head and asked, "President, how is this tank?" ”

Xiao Zhenlei lit a cigarette and smoked it, flicked the ash in the ashtray, and said: "Overall, the performance is not bad, how thick is the front armor of the tank?"

Cai Guodong replied: "The same as the side armor!" ”

Xiao Zhenlei shook his head and said: "The front armor almost has to face the enemy's artillery fire and large-caliber heavy machine gun fire head-on, the armor is too weak, at least it is more than 30 mm less, and the shape design of the tank is not bad!" You can consider forming a tank division, but the number of tanks cannot be produced a lot, at most the number of equipment can only be produced and equipped, after all, now both in mechanical technology and manufacturing technology are not very mature, in technology to strengthen research, such as protection capabilities, travel speed and maximum travel range, these must work engine technology, try to improve the power of the engine, reduce fuel consumption, reduce noise, you can install a radio intercom, in addition, I just looked at it, The steering system of this tank seems to be a bit dull, to improve the performance of its steering system, and also, can you add sights to the turret? I just saw that the hit rate of the shelling is not very good, let's solve these problems first and then carry out production, and then carry out production after the drawings and manufacturing technology are finalized, and first produce the number of divisions."

Cai Guodong heard Xiao Zhenlei's words and knew that there were still many problems with this tank, so it still needed to be improved. The most obvious is the problem of the steering system and the turret sight. He promised: "Okay, after solving these problems, the tank that will be finalized will be named Dragon Battle Type A, right?" ”

Xiao Zhenlei nodded in agreement: "Okay!" ”

After leaving Mukden Machinery Manufacturing Company. Xiao Zhenlei and others then took a transport plane to Nanjing, and after the plane stopped at a military airport, they took a convoy to an arms production company. This is also a state weapons manufacturing company, which has been established for three years and produces not only firearms, bullets, shells, but also artillery.

This company also has an R&D team, and in addition to the huge production hall, there is also a weapon performance test site, where the convoy stops, and this weapon performance test site is large, and it is surrounded by three hills in the middle. All three hills are within the range of the weapons performance test site.

The main person in charge of the weapons manufacturing company and his party had been waiting at the test site for a long time, but when the convoy stopped, they came up to meet them, and after a salute, everyone came to the stands to watch the firing effect of anti-aircraft machine guns and anti-aircraft guns.

"Let's get started!" Xiao Zhenlei said to the head of the weapons manufacturing company.

The person in charge immediately agreed: "Yes, President!" ”

After the order was given, several trucks each dragged into the test site with a twin anti-aircraft machine gun, which were mounted on two wheels, and each truck had six soldiers in its compartment, all of whom were gunners.

After the truck stopped. The soldiers jumped out of the trucks, the trucks removed the ammunition boxes from the trucks, and then used tools to separate the locomotives loaded with anti-aircraft machine guns from the trucks, and the trucks then drove aside to wait, and the soldiers used tools to connect the locomotive loaded with the anti-aircraft guns to the ground. The machine-gun emplacements were thus erected.

Two ammunition boxes were moved, one on the left and one on the right, and the bullets were loaded. The first gunner is responsible for height and direction, and the second gunner is responsible for the route, speed, distance and discharging when the gun is released when the gun is withdrawn. That is, the Zhuyuan fixed loader, and the third and fourth gunners are the left and right loaders. The five gunners were bombardiers, and there was also a squad leader, and there were 6 people in a machine gun squad.

Under the command of the squad leader, the soldiers of the anti-aircraft machine gun squad exercised their duties one after another, and the muzzles of the anti-aircraft machine guns constantly changed direction and height under the operation of the soldiers.

"Fire!"

"Da da da ??????".

The rate of fire of the anti-aircraft machine gun is very fast, after firing, the two barrels keep spewing out tongues of fire, and the shell of the anti-aircraft machine gun keeps throwing out shells, and the shells hit the ground with a rattling sound, and the sound of the machine gun firing is very similar to the sound of a loom.

As the speed of the aircraft gets faster and faster, in fact, the probability of the anti-aircraft machine gun being able to hit the fighter is quite low, and the anti-aircraft machine gun plays a much greater deterrent role than lethality.

One ammunition box contained one hundred and fifty rounds of anti-aircraft machine gun ammunition, one on the left and one on the left, and it was quickly exhausted, and as soon as the bullets were exhausted, the squad leader shouted: "Change the ammunition!" ”

The three and four gunners immediately ran over from behind, each carrying an ammunition box, removed the empty ammunition box from the anti-aircraft machine gun, and then loaded the ammunition box, and the machine gun continued to fire, and the bullet shot into the air and fell in the distance.

Judging from the shooting height, rate of fire and steering flexibility, the performance of this twin-mounted anti-aircraft machine gun is still very good, Xiao Zhenlei thought about it and asked the person in charge: "Can it be fired flat?" ”

Xiao Zhenlei thought they wouldn't, but who knew that the person in charge promised: "Yes, President, I'll order them to shoot flat now!" ”

The order was given quickly, and the gunners who received the order began to lower their guns and fire at the side of the bare hill in the distance, only to see that the opposite hill wall was smashed into rubble, and many large rocks were knocked down from the mountain wall.

This time, several generals and officers accompanying them were shocked to see that anti-aircraft machine guns could have such a destructive power in flat fire, and a major general's chief of staff looked at the potholes in the mountain wall in the distance in amazement, and then couldn't help but say: "My God, how dare this thing have such great power?" If this hits a person, won't it break the person in two? ”

Xiao Zhenlei shook his head and said: "This twin is only 12.7 mm caliber, if it is replaced by a quadruple 14.5 mm caliber, the tank will not be able to prevent its strafing, and the thickness of the British tank's armor is only 6 mm." Where can it stop its strafing? ”

The head of the weapons manufacturing company nodded in agreement: "Yes, the big president. The bullets of the 14.5 mm quadruple anti-aircraft machine gun we developed can be used for anti-tank purposes, and there is no problem in fighting planes. This bullet is extremely large, it is characterized by a very large firing charge, the cartridge case is 114 mm long, the volume is 42.5 ml, the mass of the whole bullet is more than 200 grams, the warhead weighs 60 grams, we have also developed an armor-piercing incendiary bomb, which can penetrate 32 mm armor within 500 meters when hit vertically, and the British tank armor is only 6 mm. Simply vulnerable in the face of such bullets! ”

Xiao Zhenlei waved his hand and said, "Then what are you waiting for, drag out the quadruple anti-aircraft machine gun to test the power!" ”

The person in charge seemed to be a little excited when he heard this, and immediately gave an order, and a truck dragged a four-wheeled locomotive over, and a quadruple anti-aircraft machine gun was fixed on the four-wheeled locomotive, and the truck stopped, and the machine gunner door that jumped from the truck began to work.

At this time, a tracked thick tank also drove in, and looking at this tank, you knew that this was the Longzhan Type 1 tank that I had seen in Mukden before. With an armor thickness of 8 mm, it certainly could not withstand the flat fire of a 14.5 mm anti-aircraft machine gun. The Dragon Fight 1 tank stopped after driving under the hill wall, the lid on the top of the tank was opened, and the crew climbed out of it one by one to line up in front of the tank. Then they ran together and left the tank.

This quadruple anti-aircraft machine gun was a very heavy weapon and required car towing. The rotating part of the entire machine gun is mounted on a four-wheeled gun cart, and when firing, four jack-type seat plates are lowered to support the entire gun cart at four points. The four wheels were lifted and hung in the air, and the four seats of this machine gun were plated on the ground to jack the locomotive. It became a combat state.

There was a buffer device with horizontal coil springs between the wheels and the gun carriage to avoid violent vibrations of the entire machine gun when towing the march on uneven roads. The cartridge chain box is on the left and right sides of the barrel. Two on each side, pitching and rotating with the barrel.

A gunner sits on a seat behind the gun, turns the steering wheel with his left hand, and rotates the high and low machine wheel with his right hand to control the pitch and rotation of the gun. Since the anti-aircraft machine gun is a weapon that mainly shoots at moving targets in the air, the firing sight is more complex than the light and heavy machine gun used by the infantry, and it is necessary to set not only the distance, but also the flight course and flight speed of the target.

The loader first fixes the bullet press on the toolbox or other plane, first inserts 4 or 5 rounds of bullets into the first bullet chain, puts them into the groove of the bullet press, and then inserts them into the bullet chain link according to the ratio of 1 tracer bullet interspersed with 4-5 ordinary bullets, and loads them into the ammunition supply box after pressing 150 rounds. The No. 1 and No. 4 gunners respectively held the tow bar and the fixed frame, and the No. 2 and No. 3 gunners respectively turned on the brake switches of the front and rear car bodies, and after hearing the squad leader's "drop the gun" command, the No. 1 and No. 4 gunners pushed the tow bar and the fixed frame inward at the same time to make the machine gun fall to the ground, and the No. 2 and No. 3 gunners turned off the mobile switch. After the rough level, the four gunners went to the front body, the right gun, the left gun, and the rear body turned the knob of the jack together to make the wheels off the ground (about 10cm), and the squad leader opened the level cover of the bracket and instructed each gunner to turn the jack until the bubble of the level was centered.

The angle of fire of the gun must be about 30 ° when loading, and its operation is generally carried out by the No. 3 and No. 4 gunners at the same time, pulling the missile circlip outward, opening the cone and the missile cover; The card shoot that presses down the bracket pulls out one-third of the ammunition supply box outward, opens the box cover, takes out one end of the bullet chain, then pushes the ammunition supply box back to its original position, loads the bullet in the rear ammunition supply box into the ammunition receiving machine of the gun body below, and makes the bullet plucking tooth and the bullet blocking tooth jam the first bullet; Cover the cone-shaped body, and then load the bullet of the front feeding box into the ammunition receiving machine of the upper gun body, and pull the pull handle of the upper and lower gun body with both hands at the same time, so that the bolt is blocked by the blocking iron, send back the pull handle, lift the firing rod upward, and put it back into the bolt, that is, it is in the state of taking the bullet. Pull the handle again, so that the bolt is blocked by the blocking iron, and the machine gun is ready to fire.

"Fire!" The squad leader gave an order.

The flat-firing bullets fired by the quadruple anti-aircraft machine guns were a storm of metal, and suddenly the side of the tank in the distance was instantly smashed into a sieve, and the 8 mm thick armor defense was not much stronger than a rag in front of this kind of anti-aircraft machine gun.
