"GENERALLY, THE WEIGHT OF A HORSE-DRAWN VEHICLE IS ABOUT 300 TO 400KG. THE SPEED OF TRAVEL IN A DAY AND NIGHT IS AS FOLLOWS, AND IT CAN TRAVEL 40 KM ON THE ROAD AND 25 TO 30 KM ON THE DIRT ROAD. IN THIS CASE, IF YOU WANT A MULE-HORSE FORCE TO BE ABLE TO MANEUVER QUICKLY, A SINGLE HORSE CANNOT CARRY MORE THAN 400 KG OF CARGO. This should be the upper limit of the weight of the fast maneuver of the mule-horse mobile unit! ”

In Xu Jie's imagination, the slowest part of the Russian mobile force cannot be slower than the road speed of 40KM a day and night, because speed is their only advantageous condition, which is based on the situation that the German infantry cannot catch up, as long as this speed bottom line can be guaranteed, then it can outrun most of the German troops! Of course, if you run into a relatively small number of armored troops from Germany and have a relatively short journey, it can only be said that you are unlucky, you have really been bitten, and you will not be able to escape......

As the main support weapon of the Russian army's mule and horse troops, the 300 to 400KG infantry gun is slightly insufficient, this thing is at most a Type 92 infantry gun according to the current level, the 92 infantry gun is less than 4KM range, and it is still too thin to carry out regimental combat missions. AS FOR READY-MADE WEAPONS, THE FRENCH 75MM GUN SHOULD BE GOOD, THIS THING IS ABSOLUTELY ADEQUATE, IT CAN HIT TANKS, PILLBOXES AND INFANTRY, BUT THE WEIGHT OF MORE THAN 1.2 TONS MAKES IT DIFFICULT FOR THESE WEAPONS TO MANEUVER QUICKLY.

IN ORDER TO BALANCE THE RELATIONSHIP BETWEEN PERFORMANCE AND WEIGHT, XU JIE PLANS TO REFER TO THE M1A1 75MM LIGHT HOWITZER FINALIZED IN THE UNITED STATES IN 1927. This gun weighs just over 580 kg when using the M8 gun mount! The pitch angle is from -5 degrees to 45 degrees. The horizontal angle is 6 degrees. The maximum firing range is 8925 meters! The normal bullet weighs 6.241 kg. From the point of view of performance, this thing is definitely the best infantry gun in World War 2, although it is not certain what virtue it is made at the level of skill that cannot be achieved in the first war, but some of the design concepts can be referred to.

First. THE WEIGHT OF THIS GUN COULD NOT EXCEED 700KG, AND IT HAD TO BE ABLE TO BE SPLIT AND COULD BE TRANSPORTED SEPARATELY BY A SINGLE HORSE IN PEACETIME, AND THREE WAGONS FORMED A COMPLETE RUNNING GROUP. And it can be quickly installed and deployed in wartime, and the whole gun can be towed in a short time after the fight. Second, in order to reduce the weight as much as possible, the hydraulic booster and the reset mechanism are combined into one. At the same time, in order to reduce the height of the gun and make the whole gun as compact as possible, the gun wheel adopts a down-mounted design, that is, in the firing state. The actual central axle of the two wheels is under the center line of the two gun wheels, which requires the installation of a "ball-and-socket joint" connection mechanism. Third, in order to optimize the horizontal firing range, Xu Jie can also get a bipod for this light artillery. However, the weight will go up.

And after the solution of light artillery, new light weapons. Huaxia also needed to design some tanks for the Russians. AFTER ALL, IN THE FACE OF THE GERMAN'S ARMORED FORCES, THE ANTI-ARMOR CAPABILITY OF THIS LIGHTLY ARMED UNIT IS REALLY SAD, FOR EXAMPLE, THE 75MM LIGHT ARTILLERY JUST MENTIONED ABOVE, UNDER THE CONDITIONS OF WAR II, THE MUZZLE VELOCITY OF THE ARTILLERY PRODUCED IS ONLY MORE THAN 300 METERS. If you build it now, you can have 250 meters, Xu Jie will be very satisfied. It may be a little more difficult to get a tank with a muzzle velocity shell. As for large-caliber machine guns? With tungsten armor-piercing shells, most armored vehicles can be defeated, but it is better to wash and sleep in the face of tanks.

The Russians seem to have one thing in common when designing any heavy weapon, and that is that they don't care much about human and machine performance. To put it bluntly, the comfort of the driver is always the last. For example, the famous T34 tank, its personal space and handling performance are absolutely nightmarish. So in practice, the users of these weapons may not be able to play their role as they should. Xu Jie believes that for those Russian armored soldiers who have been systematically trained and have a certain degree of tactical literacy, it is necessary to give them a relatively comfortable environment.

Another point is that Xu Jie hopes to ensure the survival rate of these skilled tankers as much as possible. It is almost impossible to change the mind of the Russian government. The only thing that can change is the design. And referring to the various tanks in the previous life, I am afraid that the front engine of Merkava will be the most suitable choice. In front of the driver, in addition to the armor, there is also an engine and gearbox, even if the armor is really broken, there is an engine to block it, and the occupant from the rear of the car will have a higher birth rate. But the only problem with this is that the frontal projection will be relatively large, which increases the area of the bomb.

With the current industrial level of China, it is really difficult to build a tank that can be comparable to Germany in all aspects while being smaller in weight than German tanks. So the trade-offs become very important. Xu Jie's first requirement was to ensure mutual penetration. This means that my armor can be thinner, but my artillery must be able to penetrate the opponent's armor. IN XU JIE'S PLANE, CHINA'S TYPE 89 120MM CAREFUL ANTI-TANK GUN WAS BORN UNDER THIS CONCEPT, AND THE ARMOR PROTECTION WAS NOT EVEN AS GOOD AS THAT OF A LIGHT TANK, BUT THE POWERFUL 120MM SMOOTHBORE GUN WAS ENOUGH TO MAKE ANY OPPONENT OF THE SAME PERIOD FEARFUL. So firepower must come first.

One of the biggest advantages of Russia or China over Germany is that there is enough tungsten ore! So it is possible to equip the tank with a certain number of tungsten alloy armor-piercing shells. WITH A HIGH-HARDNESS ARMOR-PIERCING WARHEAD, XU JIE THINKS THAT A 57MM LONG-BARRELED CANNON IS ENOUGH. It is important to know that the No. 4 tank in the 2nd World War still used the long-barreled 50L gun for a period of time. In terms of engines, it is not clear how much horsepower this engine can have, but according to historical estimates, it may not be possible to get an engine above 130 horsepower before World War 1, and the most important thing is armor protection. And that's the hardest thing to do.

Under the limitation of technical conditions, it is impossible to make a tank with excellent defense in all directions, so Xu Jie decided to still learn from the advanced experience of later generations, if the defense in each direction can not resist the opponent's artillery, then let the defense on the most vulnerable direction can resist the opponent's attack, so Xu Jie's defense mark for the tank designed for the Russians is that the front can block the attack of the 50MM gun, and the side is reduced to about 15MM, and the area is still partial. CAPABLE OF PROTECTING AGAINST LARGER SHRAPNEL, AS WELL AS 37MM AND 47MM GRENADES. The turret may even be considered to be designed as open to save weight if the situation warrants. It is expected that the weight of the tank as a whole will not exceed 15 tons.

The assault gun designed by Xu Jie for the Russians also follows this principle, but the height of the vehicle is reduced as much as possible, and a more powerful gun is installed at the same time. XU JIE NOW ESTIMATES WHETHER HE CAN FIT A 75MM CANNON WITH A WEIGHT OF 15 TONS? If it can be successful, then it is estimated that no vehicle in the 1st battle will be able to block its thunderous blow. WITHOUT CONSIDERING THE TURRET AND WITH THE ARMOR PROTECTION ONLY EMPHASIZING THE FRONT, XU JIE THOUGHT THAT A COMPACT 75MM CANNON SHOULD FIT IN.
