After Mu Tianyu settled Zhang Letong, he returned to the guest house and continued to conduct their special training with Jin Chen and Zhao Zhennan.

The special training plan formulated by Mu Tianyu is based on the basic test, and has made necessary adjustments according to each person's situation, so as to achieve the best results according to individual conditions.

When Zhao Zhennan saw the training plan, he felt that Mu Tianyu might take care of him, and the amount of training arranged was lighter than that of Mu Tianyu and Jin Chen.

He said a little incredulously: "Xiaoyu, my grades will never reach the level of the two of you." ”

"Brother Chengnan, our competition is a comprehensive strength, and of course we will also pay attention to individual individual results. And the individual results are very stable for you, and there are no dead ends. ”

Zhao Zhennan thought about himself, before he came, he had already run 80,000 kilometers when he practiced cross-country, which is equivalent to running two laps around the earth's equator; Practice high obstacles, jumping down from a 5-meter-high rope ladder 7,000 times; Practicing low obstacles, crawling and climbing 100 kilometers under a one-foot-high low-pile barbed wire fence is equivalent to climbing 3 laps around Beijing's Third Ring Road; practiced bomb throwing, and threw a total of 620,000 handleless grenades, totaling 370 tons, which can fit a train; Practicing obstacle swimming, he swam a total of 8,000 kilometers in a swimming lane full of water obstacles, which is equivalent to crossing the Bohai Strait 60 times.

Such a large amount of training is not something that can be completed in a sudden attack, so what Mu Tianyu said is right, and he has nothing to say.

And Mu Tianyu and Jin Chen, they had never trained so systematically with Zhao Zhennan before.

Therefore, their test results are not stable to a certain extent, and they need to accumulate a certain amount of training to achieve stable solidification.

And Jin Chen, suddenly, put forward an idea for the single competition subject of grenades. He asked Zhao Zhennan: "Is a handle-handled grenade farther and more accurate than a handleless grenade?" ”

Zhao Zhennan really studied this question, and he immediately replied:

"China's scientific research department once made a very comprehensive comparison, let the People's Liberation Army use handleled grenades and oval grenades to carry out throwing tests, and the test conclusion is: a handle is not farther than a handleless, nor is it more accurate than a handleless throw. The distance depends on the weight, while the accuracy depends on the level of training. ”

Zhao Zhennan also talked about a thing, he said: There is also a problem found in the test, the army often throws far away as the winner, but the competition uses training bullets, and later the live ammunition is tested, and the grenades thrown by the winners basically have no time to land, they are thrown too far, and they explode directly in the air.

When Mu Tianyu heard this, he immediately said: "According to Brother Zhennan, this school official competition may use handleless grenades, and the far throw may not add too many points, and the accuracy of the throw may be the focus of the extra points." ”

"Yes, generally speaking, when the throwing distance reaches a certain range, the score will be scored, and there is no bonus for throwing far, and if the throw exceeds or does not reach a certain range, the score will be reduced."

"Oh," Jin Chen hurriedly said, "In other words, if you throw too far, it won't add points, or even subtract points?" ”

Zhao Zhennan replied affirmatively: "Yes, at least in actual combat." ”

Mu Tianyu said: "I heard that handleless grenades cannot be thrown on inclined slopes or roofs, otherwise they will roll down to the side of the thrower." ”

"Yes," Zhao Zhennan replied, "This is a problem that must be paid attention to in the competition, if the slope or roof is on the target side, you should use the last stop position of the roll, that is, the actual explosion point, which is the score point." ”

"Oh, it's different from the previous sports games! In the sports meeting, the first landing point is used as the performance calculation point. ”

"Therefore, the information provided by Brother Zhennan is very important, and the military competition must be based on the actual combat effect." Mu Tianyu also felt that this information was very important, and he made it clear that special training should not be aimed at the standards of the sports meeting, but should be aimed at the actual combat effect.

In fact, this problem is also a common problem in our armed forces at present.

A handleless grenade, because it is light and small, is more convenient to carry and use than a handled, and can be carried more.

However, the main reason why our army is still equipped with hand-handled grenades is that the stock is too large and cannot be exhausted for a while. In addition, there is no threat of large-scale war at present, and in the spirit of the usual style of thrift and thrift, the use of handles continues to be used.

However, the PLA is also armed with new types of stemless grenades, such as the Type 82-2 grenade. This elastic performance is not inferior to that of grenades equipped abroad, and with the gradual depletion of old handle-handled grenades in stock, more and more troops will be equipped with new handleless grenades.

Therefore, Mu Tianyu said: "In this special training, we should also use the 82-2 handleless grenade as the main equipment, and the old-fashioned wooden-handled grenade as auxiliary equipment." ”

The 82-type grenade series consists of 82-1, 82-2, 82-3 and 82-2 all-plastic handleless steel ball grenades, the first three types of bullets were designed in 1982, and the 82-2 type all-plastic handleless steel ball grenades were designed and finalized in 1986, so they are also known as 86-type grenades, except for two 82-2 type grenades that have been mass-produced, the rest of the bullet types are also finalized and transferred to the technical reserve.

This kind of handleless grenade body is stamped into a spherical shell with an internal grooved A3 steel plate, loaded with 62 grams of TNT explosives, when exploding, the shell can produce more than 330 fragments of a single fragment mass of more than 3 grams, so that the killing radius of the grenade is greater than 6m, and the critical safety radius is less than 30m.

The fuze of the Type 82 handleless grenade is a flap firing needle type needle puncture fire delay time fuze, which is composed of four parts: the fuse body, the ignition mechanism, the initiating device and the insurance mechanism, and this structure is basically the same as the popular foreign flap firing mechanism. Usually use the fuse pin to fix the fuse in the fuse state, and make the firing torsion spring in the state of energy storage, when using the pin to pull out the fuse, the flap firing pin in the torsion spring under the drive of the firing cap, so that greatly improve the safety and reliability of the grenade.

As for the Type 82-2 all-plastic handleless steel ball grenade, the fragmentation bushing of the projectile body is injection molded with 1,600 steel balls and plastic, each steel ball has a diameter of about 0mm, and a layer of plastic is wrapped outside the fragmentation bushing as the shell of the grenade. In order to be non-slip and easy to hold, there are longitudinal and horizontal ribs, 5 transverse ribs and 8 radial ribs are injected outside the elastic body. There is no smoke and no flame when firing, and the flame and smoke when the delay is burned will not come out from the top, so as to ensure that the projectile will not produce sound, light and smoke during the throwing process, which is conducive to the concealment of the thrower.

The main characteristics of the Type 82-2 all-plastic handleless steel ball grenade are: simple structure, good economy, small size, light weight, and a large amount of fragments. Compared to the Type 67 wooden-handled grenade, the volume was reduced by 58% and the mass by 57%; Greater lethality, safety and reliability.
