The French "Renault" FT-17 light tank and 2C heavy tank were chosen because they still had good performances in World War II.

The Renault FT-17 light tank, the world's first tank with a 360-degree turret with a rear power compartment and a driver's seat in front of the hull, is the design of most of the modern tanks we see today.

In fact, at this time on the land of China, in addition to Zhao Yun, there was also a company equipped with tanks and armored vehicles. This is the Northeast Army led by the warlord Zhang Huzi, equipped with an unknown number of French-made FT tanks, and the source of Zhang Huzi's tanks is that France and other European countries are preparing to sell to White Russia to support them in their fight against Soviet Russia. As a result, when the ship arrived in Lushun, it was cut off by Zhangzi's beard and some were bought.

But this batch of tanks is very problematic, almost all of them are used second-hand, and the repaired ones are sent to cheat money. On the back side of the FT-17 light tank, there are two induction wheels that adjust the direction, Zhao Yun is all iron, but the Northeast Army is wood-clad iron.

As for the 2C heavy tank, even if this guy is measured by the standards of World War II, it should be more appropriate to call it a super heavy tank.

When Zhao Yun looked at the design drawings of the 2C heavy tank again, all the dimensions of this tank looked very excessive: the steel monster was 10.27 meters long, 4.01 meters high, 2.95 meters wide, and the total combat weight was 70 tons, while the 1.8T Passat was only 4.87 meters long, 1.47 meters high, and 1.8 meters wide.

Moreover, its armor was also designed to protect against all weapons on the battlefield during World War I, and was very heavy, with a front of 45 mm, a side of 22 mm, and a top of 13 mm. The turret had 35 mm steel plates in the front and 22 mm in the rear.

It was also a headache for the French to drive such a behemoth, and they used engines that Germany had given to France as war reparations, and not for tanks, but for Zeppelins, 6-cylinder, 250 hp Maybach engines.

Such an engine is capable of moving the 2C tank at a speed of 12-15 km / h, depending on the road conditions. The heavy tank had a range of 150 km. The obstacle crossing performance is also very good, and it can cross the 1.70 m high vertical barrier, the 1.40 m deep trench, and the 4.25 m wide trench without difficulty. In fact, this width of 4.25 meters is also exquisite, because the canal locks in the north and east of France are 4.25 meters wide. The Big Mac requires no less than 12 crew members, and they are divided as follows:

a commander, a junior officer;

a driver, a senior non-commissioned officer;

a mechanic, general sergeant;

an assistant mechanic;

an electrician;

a radioman;

a gun commander;

a gunner;

a former machine gunner;

a rear machine gunner;

Two side machine gunners.

From the configuration of so many machine gunners, it is not difficult to see the firepower of this giant. The vehicle had a gun and a machine gun in its turret, and three machine guns in its hull. The 75-mm gun, which was its main armament, was mounted in the front turret, the gun was Type 1897, originally produced for submarines, with a shortened barrel and mounted on the 2C tank. The horizontal firing boundary is 320 degrees, and the backward direction is the dead angle; The vertical firing range was +20-20 degrees, and for accurate shooting, the gunner had a sight with a distance of up to 2,000 meters and a magnification of 2.5. 4 machine guns of 8 mm caliber. The horizontal firing range of the machine gun in the rear turret was 260 degrees. The horizontal firing range of the hull machine gun was: 50 degrees for the front machine gun and 90 degrees for the side machine gun. In battle, the 2C tank could carry a total of 124 rounds of 75-mm shells and 9500 rounds of 8-mm machine gun shells at a time, with a satisfactory ammunition reserve.

And these different divisions of weapons make the 2C tank look like a satisfactory weapon in terms of both the number and quality of weapons.

Of course, if Zhao Yun directly took out the French "Renault" FT-17 light tank and 2C heavy tank, then in Shanghainese, Nong's brain was bad.

There are patents in later generations, and there is also a saying for authorization in this era. No one will ask you where you came from, after all, there are not one or two people who have a way in this era, and if a dozen or so appear together, it will be a big problem. Moreover, the 2C tank is also a relatively advanced one, which was only delivered to the French Army in 1921, and the French are very nervous about it.

So the "Renault" FT-17 light tank was first dragged into the camp in Outer Mongolia, and under the finger of Zhao Yun, the "second knife", after a burst of beating and beating by the captured old Maozi logistics personnel, it finally became an ironclad ship, more like a tank.

Why not in Jiangnan but ask Lao Maozi's mechanic to help? In 1921, Lao Maozi's army began to use the КС tank, as well as the first ultralight tank independently developed by Russia in 1919, called the "Protected Carrier", which was operated by a machine gun and a crew prone to operate. It was with the addition of these tanks that the logistics personnel of the Soviet Russian army began to come into contact with such new weapons at an early stage. With the addition of these skilled hands, Zhao Yun's blind command can be implemented. Otherwise, find a group of people who don't even know what a tank looks like to mess around, and when will they be able to figure it out. In fact, the work began as early as the return of the servant army from Siberia, but it was not until the beginning of 1922 that there was a major development.

From this tank, there is almost no "Renault" FT-17 light tank, it should be said that it is similar to the early amphibious tanks seen in Zhao Yun's museum, belonging to the "grassroots era" amphibious tanks.

It weighs 6 tons, has a crew of 2 people, is 4.29 meters long, 2.19 meters high, and 1.67 meters wide. The power plant is located in the middle and rear of the hull, and the position of the engine configuration has been changed accordingly (FT is longitudinal spacing, rear center configuration has been changed to horizontal (side) spacing, and rear lower configuration), similar to the 1920 Italian Fiat 3000 light tank. The power of the engine is transmitted to the gearbox and side reducers located in the front of the body; When the water gear is attached, the power of the engine is transmitted backwards to the propeller-type water thruster, which pushes the tank to sail on the water. Because the engine is in the rear position, it is conducive to the longitudinal balance of the whole vehicle and prevents the tank from sticking its head when sailing in the water. Another feature of the general arrangement is that the center of gravity of the turret (machine gun tower) is not on the center line of the car body, and the position is obviously to the right, which is a choice made in accordance with the lateral balance of the vehicle. There are pontoons above the tracks to increase the buoyancy reserve. In addition, there is a rudder at the rear of the hull for gentle steering in the water.

The vehicle's main armament is a 12.7 mm heavy machine gun with a special high-level dual-purpose machine gun mount, or a 37 mm gun and a defended Harchikis light machine gun.

The power plant is 1 diesel engine that is not easy to catch fire, with a maximum power of 40 horsepower. The action device comprises 4 load-bearing wheels on each side, 2 carrier pulleys, large-diameter driving wheels and inducing wheels, crawlers and balanced suspension devices, etc., with the driving wheels in front and the inducing wheels behind, with a maximum speed of 40 km/h, a maximum range of 230 km, and a maximum speed of 6 km/h.

In fact, as early as 1916, when the tank had just entered the battlefield, it encountered the incident of being blocked by a small river in the battle, thus delaying the fighter. And the waterways in the south of the Yangtze River are famous, if you just use the ordinary Renault FT, it is estimated that you can only play sideways in a small area. Don't forget that Yixing County is full of rivers, and if this guy can't take the waterway, he won't be able to set up a position in the county.

In 1916, the Russian inventor Tchaikovsky designed an amphibious tank test vehicle, but it was not built. In 1920, Tchaikovsky designed and trial-produced a three-man amphibious tank called "Teplokhod", which was armed with a 76.2 mm gun and weighed 10 tons, but the performance of the tank was too poor for research purposes and could not be mass-produced.

The so-called amphibious tank is a tank that can walk on land and travel on water. Not long after the advent of tanks, some countries tried to develop an amphibious tank that could cross mountains and rivers and be unimpeded on land and water.

During World War I, France and the United States were the first to begin full-scale development of amphibious tanks, and at that time, people called this unique armored vehicle a car boat or amphibious armored vehicle. In 1918, the French company Schnader developed an amphibious tank called Schnader-Laurent, which was larger, weighed 7.7 tons, and was equipped with a 37 mm gun and one machine gun. In 1919, the French company Renault produced the FT amphibious tank, which had no turret and a new ship-shaped hull, and the French army was going to use it as an armored personnel transport vehicle. Therefore, based on the intelligence of various countries, it seems that the tank designed by Zhao Yun is a step higher than the amphibious tanks of other countries, but except for the victory in being able to cross the river, the others are not much stronger than the Renault FT on land that the Japanese are already using.

As for the 2C tank, the biggest problem for this French heavy tank was: how to transport these 70-ton guys over long distances.

Obviously, it would be impossible to move this kind of tank, which dominated at a very slow speed and huge body, and let it maneuver to its destination on its own through the guò road network in the south of the Yangtze River, which crisscrossed the waterways. At this time in Jiangnan, many bridges were still wooden, and Zhao Yun had no hope that they would bear a load of 70 tons.

The French also had a headache for this, and came up with the idea of creating two special transporters for each tank, which were connected to the front and rear of the 2C tank, and the tanks were "suspended" from both ends, which themselves became part of the transporter and were transported by guò rail.

The idea is good, but it is difficult to implement. Rail transportation of 2C tanks is a time-consuming and complex task, which requires first special equipment "cranes", and then on lines with little traffic. Considering that the required equipment would be carried with the vehicle, a whole train would be needed for just 3 2C tanks. The transport route was also carefully chosen, since the turning radius of the railway used by the train carrying the 2C tank could not be less than 75 meters. At the tactical level, the restrictions on transportation made the 2C tank very dangerously dependent on the state of the railway, and Zhao Yun saw the shortcomings of the French.
