Chapter 1738: Ergonomics
The heart has been inclined to this plan, Kawasaki Meijing put this plan together, continue to read the documents at the military level, Japan in Juneau, has already retreated, the US offensive is like a tide, in the past 21 days, the US army has a total of 7 attack days, each day has achieved great results, although later, because of the relationship between the enemy, Japan intends to retreat, but Juno can not support for long, maybe try his best, can support 2-3 months, but to reach winter, it is simply impossibleThey held out on Juno's side just to wait for the right moment, and when the Sakura plan was executed, they could leave.

In the winter of last year, Japan completed the Juno Line, and in this year's spring, summer and autumn operations, the second and third lines of defense have not stopped, that is to say, even if the U.S. military can break through the Juno Line and take Juno, the whole of Alaska will not completely collapse, they will use the second and third lines of defense to delay the U.S. military, the entire vicinity of Juno, plus the southern part of Alaska, there are at least 300,000 square kilometers of land, and Japan will deploy here inch by inch to delay the attack of the U.S. military.
Now, everything is going well with the Sakura plan, with the number of American tanks captured by Japan reaching a new high, and now it can dispatch more than 5,000 armored forces at most, which is a huge force for attacking the Japanese defense line, 5,000 tanks may not be able to capture the position on a large scale, but for the unprotected inland, 5,000 tanks are a big killer, just think about it, when 5,000 steel monsters enter the city of tens of thousands, or even hundreds of thousands of people, 10,000 machine guns will cause a lot of killing, not to mention the defenseless infantry, when there is no firm position, when they encounter the attack of a tank cluster, it is difficult for them to even run, a person, even if it is a 100-meter sprint speed, can run into 10 seconds, in later generations is already the smallest handful of people in the entire world, or under professional equipment, professional running shoes, even if it is 100 meters and ten seconds, the speed per hour, is only 36 kilometers, barely similar to the maximum speed of the tank, wearing military uniforms and protective gear, holding a gun, It is impossible to run for 10 seconds, and in such a situation, it is waiting for the tank to be harvested.
It was with full confidence in the armored forces that Kawasaki Meijing threw himself into this plan, and now he just thought a little more thoroughly, and executed this plan a little better, and on the premise that all the tank modifications were not finally completed, he still had time, at least a month, for the final temporary cramming.
The winter in Alaska is unusually cold, but the summer is more suitable, especially near the Pacific Ocean, because it is deeply affected by the ocean climate, the perennial temperature difference is not large, even in summer, it is not much hot, but in the tank training ground, it is full of warm atmosphere, hundreds of armored monsters are divided into different areas here, in the driving, turning, basic coordination of tactics, in short, the roar is endless.
This is not the initial training ground, with the approach of the US army, it has recently reached the range of 17 kilometers in Juneau, if the artillery is assumed here, the entire eastern part of Juneau, there will not be any safe place, even in the west, it is not safe, who knows when the armored cluster of the American army will suddenly charge here, when the tank is not equipped with artillery fire, the tank is strong and weak, even the tank cannot deal with the tank, the tank is equipped with ordinary machine guns, It was impossible to penetrate the thick armor of the tank, at most it was a barrier for infantry and defensive positions.
Therefore, under the arrangement of the War Department, and for the sake of the future, and for the better implementation of the Sakura Plan, the entire training ground has been moved 85 kilometers to the north, which is already in the absolute hinterland of Juno's rear, and is not far from Japan's second line of defense.
In the days when Kawasaki Meijing was not there, the tank training was carried out as usual, and the division commander under him was in charge, under the premise that the number of modified tanks was small, Japan also organized a large number of American tanks for basic exercises, of course, this can only train the most basic, regardless of the premise of the battle, driving exercises, as for the combat exercises, they are replaced by land exercises, mainly machine gun firing, so that it can not be compared with the modified ones, but it is also acceptable.
The Chinese side has been very thorough in the modification of the tank, not only replacing the power system and shock absorption, but also carrying out a comprehensive modification of the weapon system, and the tank's machine guns have been reduced from a few to four and finally reduced to two, not in separate designs, not separately, each machine gun can be designed independently, it is fixed and parallel to the tank around, becoming a twin machine gun, controlled by a tanker.
Saving manpower and saving weight has always been the focus of the Chinese side of modification, under the premise of a certain power, the reduction of weight and manpower represents an increase in speed, because of the relationship between the duplex, the members of the tank, also from the previous 6, has become 3, a driver, a machine gunner and the remaining one maneuver, when the driver has a problem, can help the driver, when attacking, can help the machine gunner to reload is a panacea.
According to the premise of 5,000 armored forces now, the standard configuration of each tank is 4 people, and in the march, it can reach 4, and when it comes to real combat, it can be reduced to three, or even two, so that there is some spare strength. In this way, the entire expedition will reach 20,000 main forces, and 15,000 logistics personnel will be much less than the 40,000 expected before, which will reduce logistics a lot.
According to the standard of 40,000 people, one person's daily food and water, such a basic material, at least 3 kilograms or more, or even more, less than 10,000 people, which means 30 tons, China did not leak to Japan, under the premise of how large-scale logistics supply can be guaranteed, such a reduction is conducive to long-term operations.
When Kawasaki Meijing arrived, the entire training ground was in full swing, a large number of replenished tanks, so that Japan was more confident, personnel for Japan, is the most worrying problem, Japan does not even have to be like before, once again launched a call order to all personnel, just on the basis of the original, a simple adjustment is good, in this premise, the final shortlisted personnel more than 90,000 people, will be selected among the best, In the end, the total number of 35,000 people, together with the 300 or so people supported by China and 1,200 people selected from various machine factories in Japan, will be the final logistical force, which will be mainly responsible for supporting the entire Sakura project, so that the number of personnel can be kept to a minimum.
Just north of Juneau, in the open field near the second line of defense, tank training is in full swing, some of which are still training on American tanks, but as the modification continues, more and more people have gone to the newly modified tanks, and unlike the American tanks, these tanks have been greatly praised.
Some tankers who have driven US tanks, compared the US tanks with the newly modified tanks, and immediately felt the difference, comfort, the US tanks are simply a crazy bumpy ox cart, although it can drive more than 25 kilometers, it has already bumped people and is about to fall apart, not to mention 12 hours of continuous driving, even if it is five or six hours, it can't bear it, unless the speed is slowed down.
I heard before that Chinese engineers modified the tank to a maximum of more than 40 kilometers, which made the top management very happy, but the drivers at the bottom, they were not happy at all, the speed of about 25 kilometers, every day at a speed of about 20 kilometers, one or two hours of high speed, it was bumpy and about to fall apart, only to rely on the will to insist, if 35 kilometers, or even 40 kilometers, what kind of feeling it would be, maybe the war has not been fought, people will be finished.
After trying the Chinese modification, at 25 kilometers, basically, the tank is only a slight shaking, which is more comfortable on it, and the previous US tank has a different feeling, it will not be tired at all, although the 35 km shaking is a little larger, but it is also in the range of acceptance, which is much better than the American tank, especially in training, it is very obvious, in the past, the US tank, at most 2 hours, must be replaced, now, a person can even hold on for three or four hours, In this way, the efficiency of training is greatly increased.
In this era, the era when the tank has just appeared, no one has noticed ergonomics and shock absorption and the like, in China, shock absorption has always been a problem to consider, all kinds of cars and trucks running on the land of China, if there is no shock absorption, what degree will it be bumpy, violent vibration, will also cause the reliability of the components is not strong, easy to produce wear and tear, which is one of the biggest problems of wear and tear of mechanical parts.
China can be said to have directly crossed the initial stage of the appearance of the car, directly took the route of shock absorption, the excellent all-in-one machine and material science, so that the shock absorption is not a big problem, on these tanks, the engineer only made a little modification to the support surface, and completed the design of shock absorption, using not spring shock absorption, but more easy to produce and maintain torsion shock absorption, for a tank with a speed of no more than 40 and a total tonnage of no more than 18 tons, this is enough.
If it weren't for the fact that the overall structure was not designed in China, and let the Chinese engineers design and produce the whole, 35 kilometers might be as comfortable as 25 kilometers, and there would not be much shaking. In this case, even if it is the highest speed, there will be no problems, the comfort level is greatly increased, this comfort level can greatly increase the combat efficiency of the Japanese army, to a certain extent, it has a huge help for the Sakura Plan, and even under the premise of multiple drivers, it can travel day and night, which has huge benefits for the Sakura Plan.
