The plane landed at the Mukden military airfield, and there were already more than a dozen cars waiting here, among which there were seven or eight steam-skin pickup trucks loaded with soldiers, and the soldiers were fully armed, in addition to rifles, they were also equipped with light machine guns, heavy machine guns, grenadiers, mortars, and other weapons.

The team soon arrived at Fengtian Machinery Manufacturing Company, which is a machinery manufacturing company established less than two years ago, belonging to the military equipment production unit, but the strength of this machinery manufacturing company should not be underestimated, it not only has the largest machinery manufacturing capacity in Northeast China, but also has one of the country's top mechanical technology research and development capabilities, Longzhan 1 tank and Cheetah 1 armored vehicles are developed and manufactured by this company.

Although the arrival of Xiao Zhenlei and others has attracted the attention of many people in the company, because it is a militarized management, every staff member and worker is very conscious and did not come to watch, and they are meticulously doing their own work, which is also required by Xiao Zhenlei in advance and cannot affect production.

Several supervisors of the machinery manufacturing company stood straight under the office building, and after Xiao Zhenlei and Cai Guodong came down, several supervisors stepped forward one by one to salute, and Xiao Zhenlei and Cai Guodong and others shook hands with them respectively.

After the greetings, Manager Wan, the main person in charge of the company, asked: "President, General Cai, the tanks and combat vehicles have been prepared at the test site, do you want to go over now?" ”

Cai Guodong looked at Xiao Zhenlei, Xiao Zhenlei waved his hand and said, "Go now, lead the way!" ”

"Yes, President!" Manager Wan agreed to drill into a car, and Xiao Zhenlei and others also got into the car. After all, the manufacturing company occupies quite a small area, two kilometers from here to the test site. It takes a lot of time to walk there, but you can only save time by car.

On the way to the test site. Looking out of the car window, the road cars were parked with neatly arranged tractors, harvesters, military trucks, jeeps and other vehicles of different models, and they were not visible until the convoy reached the entrance of the test site.

The convoy drove directly into the test site and stopped, there was a stand on the side of the test site, Xiao Zhenlei and others walked to the stand and sat down, and directly opposite the stand, there were three tanks and three armored personnel carriers parked in the open space of the test site.

There was a porcelain cup in front of each seat on a long row of tables in front of it, and a young man was carrying a boiling water bottle to fill each porcelain cup with boiling water.

Although it is now winter. But the sun in the morning is shining on this side, the director of the manufacturing company is still very thoughtful, maybe it has been arranged a long time ago, in addition to the porcelain cup in front of each seat, there is also a pair of sunglasses, Xiao Zhenlei picked up the sunglasses and looked at them, on the bridge of his nose, I feel that the sun is not dazzling, very good. He also praised Cai Guodong.

Manager Wan of the company walked over and bent down and asked: "President, General Cai, all the personnel have arrived, and the test site over there has been prepared, is it possible to start?" ”

Xiao Zhenlei waved his hand: "If no one else wants to come." Let's get started! ”

"Yes, President!"

After a whistle, a platoon of heavily armed infantry on the far right of the test site ran in a neat line towards the three armored personnel carriers. And in an orderly and fast manner, they got into the three armored personnel carriers, and then the doors at the rear of the three armored personnel vehicles were closed and closed inside.

Three armored vehicles, already fully loaded with infantry, began to start. A puff of black smoke erupted from one side, and the large diesel engine started. On the roof of the three armored personnel carriers, there are two soldiers each holding a machine gun, one in front of the other, the machine gun has a shield to protect the safety of the shooter, and the machine gun can be turned 360 degrees in all directions, the front machine gun muzzle is forward, and the machine gun muzzle is upward, obviously the machine gun behind is anti-aircraft and belongs to the anti-aircraft machine gun.

The maximum speed of 45 kilometers per hour can be said to be the fastest land vehicle in this era, which is the maximum speed of this Cheetah armored personnel carrier, and the maximum speed of the Mark 1 tank made by the British during this period is only 32 kilometers per hour, and the armor is only 6 mm, the armor of this Cheetah 1 armored personnel carrier is 6 mm, because it is an armored personnel carrier, it is naturally not comparable with the tank in terms of firepower and defense, it has no artillery only machine guns, But its speed and internal space are much larger than that of a tank, after all, its main task is to transport troops.

Xiao Zhenlei asked: "The machine gun behind the armored car is an anti-aircraft machine gun, right?" ”

Cai Guodong said: "Yes! ”

"When did you get it?"

"Three months ago!"

Xiao Zhenlei asked again: "What about the specific parameters?" ”

"This armored personnel carrier is mounted on a single-barreled, 12.7 mm caliber, with a theoretical rate of fire of about 550 rounds per minute, and an actual combat rate of about 80 rounds per minute, which can be used to shoot low-altitude aircraft and ultra-low-flying aircraft at an altitude of less than 1 kilometer. In addition, we have developed a double-barreled and a quadruple one, which are mainly mounted on the locomotive to form an anti-aircraft machine gun position, which is easy to move. In addition to installing a large number of quadruple anti-aircraft machine guns for air defense, each warship is also equipped with one or two anti-aircraft guns, we have developed several anti-aircraft guns of different calibers, and this work is currently being prepared, I believe that the Navy will soon submit an application for the installation of anti-aircraft machine guns and anti-aircraft guns for naval warships! ”

Xiao Zhenlei nodded when he heard this: "Yes, you can consider going ahead, this is very good, now all countries have begun to attach importance to the development of air force, the performance of the aircraft will get better and better, in addition to striving to develop more advanced and powerful fighters, we must also be ahead of the world in air defense, and at the same time we must build a good shield to defend against it while building a spear, so as not to suffer losses in the future!" ”

At this time, three armored personnel carriers drove past the stands and continued to rush towards the left side of the test site. Soon, the machine guns on the armored vehicles opened fire, the dummies in military uniforms arranged on the sides of the front were knocked down by bullets, and several trucks covered in iron were riddled with crazy machine gun bullets.

Soon, the armored personnel carrier rushed through a trench more than one meter wide, and after crossing this trench, it advanced several dozen meters and a steep ridge half a meter higher than the flat ground stopped in front, and the three armored personnel carriers climbed up to the flat ground half a meter high without hindrance.

In fact, in the Boer War, the British had officers who covered their cars with iron sheets and machine guns to make the most primitive and simplest armored vehicles for combat, but at that time, no one realized the role of armored vehicles in the war, and no one thought of continuing to study. In the history of another time and space, it was not until the end of World War I that the British created tracked and wheeled armored transport vehicles. The car had light armor and a machine gun and could carry 20 soldiers. Although the armor on the vehicles protected the soldiers from bullets, the infantry, accustomed to fighting on the move, referred to the first armoured transporters as "sardine cans" and "coffins on wheels". But in this time and space, armored vehicles in the true sense of the word have not yet been invented.

The three armoured personnel carriers climbed up the steep half-metre-high level and continued to move forward, still unabated. Soon there were obstacles in front again, three slopes appeared in front, the three armored vehicles did not have any intention of slowing down, the rear of the armored car spewed black smoke and rushed up the slope, the slope of the slope was about forty or fifty degrees, the armored car slowed down a little when climbing, but there was no sign that it could not climb.

The three armoured vehicles climbed up the coercion, then turned around and rushed towards another slope. Xiao Zhenlei asked, "How much slope was that slope just now?" ”

Manager Wan, who was standing behind him, immediately said: "President Yuda, that's a forty-five degree slope!" ”

Xiao Zhenlei asked again: "What about now?" How likely are they to roll over on a slope sideways? ”

"President, this is a thirty-degree slope, and without the interference of a strong external force, it is almost impossible for an armored car to overturn! Because although the body of the armored car is more than two meters high, its weight is in the chassis, so it generally does not overturn".

The three armored vehicles advanced sideways on the slope for some distance before entering the flat ground, in front of which there was a simulated enemy position with trenches, and the three armored personnel carriers opened fire as they advanced, and the machine guns on the roof kept firing at the dummies on both sides, and the dummies were knocked down one after another.

After rushing into the enemy position, the three personnel carriers stopped in a lateral drift, the iron gate at the rear of the car was lowered, the iron gate formed a ramp tread in front of the body and the ground, the soldiers rushed out of the combat vehicle with rifles, the first two soldiers who rushed out squatted on the ground on the ground one left and one right and kept firing at the dummy in sight, the soldiers in the carriage rushed out one by one and jumped into a traffic trench, the battle officially began, the soldiers began to start from the traffic trench to infiltrate the enemy trenches to attack, The whole tactical coordination is very skillful.

At this point in the test, Cai Guodong asked: "President, what do you think of the performance of this armored personnel carrier?" Are the tactics of a quick assault on enemy positions able to play a strong role? ”

Xiao Zhenlei nodded and said: "Yes, this armored vehicle is good, and the tactics just now are also good, but the soldiers can't completely break through the enemy position when they are fighting, after all, the combat vehicles and tanks are not invincible, if the enemy digs anti-tank trenches in front of the position, the tactics of relying on combat vehicles and tank assault will be ineffective!"
