Chapter 1738 Ergonomics
I already tended to this plan in my heart. Mikatsu Kawasaki put this plan together and continued to read the first-level documents of the military. Japan has already wanted to retreat in Juno. The US military's offensive is sensational. In the past 21 days, the US military has achieved great results in a total of 7 attack days, and each day has achieved great results. Although Japan intends to retreat due to the defeat, Juno cannot last long. Perhaps he will do his best to support it for 2-3 months. But it is impossible to reach winter. They stick to Juneo's side just to wait for the opportunity. When the Sakura Plan is implemented, they can leave.
Last winter, Japan completed the Juno Line of Defense. During the battles between spring, summer and autumn this year, two and three lines of defense have not stopped. In other words, even if the US military can break through the Juno Line of Defense and take Juneau, the entire Alaska will not completely collapse. They will use the second and third lines of defense to delay the US military. The entire vicinity of Juneau, plus the southern part of Alaska, there is at least 300,000 square kilometers of land. Japan will deploy defenses inch by inch here to delay the US military's attack.
Now, the Sakura Plan is going well. With the number of Japanese captured US tanks, it can now dispatch more than 5,000 armored forces. This is a huge force. It is used to attack Japan's defense line. 5,000 tanks may not be able to capture positions on a large scale. However, for the unprotected inland, 5,000 tanks are a big killer weapon. Just think about it. When 5,000 steel monsters enter a city with tens of thousands, or even more than 100,000 people, how big a killing will 10,000 machine guns cause.
Not to mention the defenseless infantry, when they encounter the attack of tank clusters without a solid position, it is difficult for them to run. A person, even if he is sprinting at a hundred meters, can run for 10 seconds, is already the smallest group of people in the world in later generations. Under professional equipment and professional running shoes, even if it is 100 meters and 10 seconds, the speed per hour is only 36 kilometers, barely similar to the maximum speed of a tank. He is wearing military uniforms and protective gear, and holding a gun, and he can't run for 10 seconds. In this case, he is waiting for the tank to harvest.
It was because of his full confidence in the armored forces that Mikatsu Kawasaki devoted himself to this plan. Now he was just thinking more thoroughly and implementing this plan better. Before all the tank modifications were finally completed, he still had time, at least one month to use for the final temporary cramming.
The winter in Alaska is extremely cold, but summer is more suitable, especially near the Pacific Ocean. Because it is deeply affected by the ocean climate, the temperature difference is not very large all year round, and even in summer, it is not much hotter. However, the tank training ground is full of warm atmosphere. Hundreds of armored monsters are divided into different areas here, driving, turning, and basic tactics. In short, the roar is endless.
This is not the initial training ground. With the approaching of the US military, it has recently arrived at the 17-kilometer range of Juneau. If the cannons are assumed to be here, there will be no safe place in the east of Juneau. Even in the west, it is not safe. Who knows when the US armored cluster will suddenly charge here? When the tanks are not equipped with artillery fire, the tanks are strong and weak in defense. Even tanks cannot deal with tanks. Tanks with ordinary machine guns cannot penetrate the thick armor on the tanks at all, and at most they can provide barriers to infantry and defensive positions.
Therefore, under the arrangement of the Army Department, in order to fail to implement the Cherry Blossom Plan, the 85 kilometers of the entire training ground migrated northward was already in the absolute hinterland behind Juno, and not far from Japan's second line of defense.
During the days when Mikatsu Kawasaki was not there, the tank training was carried out as usual, and the division commander under his command was responsible. With the small number of modified tanks, Japan also organized a large number of US tanks for basic exercises. Of course, this can only train the most basic and unconsidered combat, and the driving exercises will be carried out. As for combat practice, it will be replaced by land practice, mainly machine gun firing. In this way, it cannot be compared with modified ones, but it can be accepted.
China has made a thorough modification of tanks. Not only did it replace the power system and shock absorption, but it also comprehensively modified the weapon system. The tank's machine guns were eventually reduced from a few 4 to two. They were not designed separately, not individually. Each machine gun can be independently designed, fixedly arranged around the tank, becoming a double-connected machine gun, controlled by a tank hand.
Saving manpower and weight has always been the focus of China's modification. Under the premise of certain power, the reduction of weight and the reduction of manpower represent an increase in speed. Due to the dual connection, the members of the tank have also changed from the previous 6 to 3, one driver and one machine gunner, and the remaining one of the motors. When the driver has problems, it can help the driver. When the attack, it can help the machine gunner reload is considered a panacea.
This reduction also caused a tank wing to shrink. According to the current 5,000 armored forces, the standard configuration of each tank is 4 people. In the marching, there can be 4 people. When fighting, it is necessary to reduce weight, it can be reduced to three or even two, which is a bit of extra effort. In this way, the entire team to go to the expedition will reach 20,000 main force and 50,000 logistics personnel, which is much less than the previous expected 40,000, which will reduce the logistics a lot.
According to the standard of 40,000 people, a person's daily food and water, such basic substances, must be at least 3 kilograms or even more, or less, or 10,000 people, representing 30 tons. Without revealing China to Japan, how large-scale logistics supply can be guaranteed, such a reduction will be conducive to long-term combat.
When Kawasaki Miyan arrived, the entire training ground was in full swing. The large number of tanks added to Japan made Japan more confident. This is the least worrying issue for Japan. Japan does not even need to initiate a call for all personnel as before. It is just a simple adjustment based on the original basis. On this premise, the number of people who were shortlisted will be selected from the best, and the overall number will be 50,000, plus about 300 people supported by China and 1,200 people selected from various Japanese machinery factories will become the final logistics force. This part is mainly responsible for supporting the entire Sakura Plan, so that the personnel can be minimized.
Just north of Juneau, on the open ground near the second line of defense, tank training is in full swing, and some are still training on US tanks, but with the continued modification, more and more people have already been on the newly modified tanks. Unlike American tanks, these tanks have received huge praise.
Some tankers who have driven US tanks compared the US tanks with the newly modified tanks and immediately felt the difference. The comfort was that the US tanks were simply a crazy and bumpy bull cart. Although they could drive more than 25 kilometers, they were almost distracted. Not to mention running continuously for 12 hours, they could not bear it even for five or six hours, unless the speed was reduced.
I heard before that Chinese engineers modified the tanks to a maximum of more than 40 kilometers, which made the senior management very happy, but the drivers at the bottom were not happy at all. At a speed of about 25 kilometers, they were usually at a speed of about 20 kilometers. After an hour or two, the bumps were almost broken. They could only rely on their will to persevere. If it were 35 kilometers, or even 40 kilometers, what would it feel like? Maybe the war would be over before it was fought.
After trying China's modification, at 25 kilometers, the tanks were basically swaying slightly, which was more comfortable. Since it felt different from the previous US tanks, it would not be tired at all. Although the 35 kilometers sway was a little larger, it was within the range of acceptance. It was much better than the American tanks, especially during training. It was very obvious. In the past, the US tanks had to be replaced for up to 2 hours. Now, a person can even last for three or four hours, which greatly increased the training efficiency.
In this era, when tanks just appeared, no one has noticed ergonomics and shock absorption. In China, shock absorption has always been a consideration. If various cars and trucks running on the land of China do not have shock absorption, they will bump to the extent. Severe vibration will also cause the components to be less reliable and easily cause wear-free losses. This is one of the biggest problems with mechanical components wear.
China can be said to have directly passed the initial stage of automobiles and took the shock absorption route. The excellent all-in-one machine and materials science make shock absorption not a big problem. On these tanks, engineers only modified the support surface a little and completed the shock absorption design. They used not spring shock absorption, but torque shock absorption that is easier to produce and repair. For tanks with speeds not exceeding 40 and total tonnage not exceeding 18 tons, this is enough.
If the overall structure is not a Chinese design, Chinese engineers can design the whole and produce it, 35 kilometers may be as comfortable as 25 kilometers and will not shake too much. In this case, even the highest speed will not be any problem, and the comfort level will be greatly increased. This comfort level can greatly increase the combat efficiency of the Japanese army. To a certain extent, it is of great help to the Sakura Plan. Even under the premise of multiple drivers, it can travel day and night, which is of great benefit to the Sakura Plan. (To be continued.)
