At the end of the year, everyone is in a hurry to finish some courses and have a stable year together. Now the indoor is a national arts class, and the outdoor stabbing class has been changed to a bomb throwing class.

The bomb instructor was also a firearms instructor, Li Zhenxiong, and asked Sangou to carry a few boxes of instructor bullets over to explain the grenade lesson.

At present, most of the army's equipment is the wooden-handled grenade of the Gongxian Arsenal imitating the German-made 24, and the 24 was modified on the basis of the 18.

24 shortened the time of the grenade to explode, 18 from pulling the string to exploding for 6 to 7 seconds, and the enemy could have time to dodge or even throw back.

24 leads are shortened to 4 to 5 seconds, and it is generally difficult for the enemy to react, or dare to throw back, but if it is too close, there is still the possibility of being thrown, but it is rare, and the probability is very low.

……

Why do low-probability things in life always appear on TV and movies? Mainly for the pursuit of artistic effects; Besides, those actors knew in advance that the smoking grenade was just a fake prop, so they were not afraid, so they picked it up and threw it out.

Really on the battlefield, these actors, you give me a reverse, how do you know that this grenade will explode in a few seconds, maybe it will explode immediately.

Normal people look at the smoking grenade, they are already frightened, and the first reaction of the fighters is to lie on the ground, rather than risk throwing back, preferring to explode on the spot in a few seconds rather than risk being killed immediately to pick it up and throw it back.

When the grenade explodes, most of the shrapnel is flying upwards, lying on the ground, basically being able to survive, and you pick up the smoking grenade like Erha, and then throw it back, once it explodes, there is basically no life, at least one hand is gone.

Even if you hit the luck and encounter something with a low probability, and you can throw it back and explode again, it is estimated that your superiors will also beat you hard afterwards, violate battlefield discipline, and do not carry out punishment, and calculate it for you.

……

Instructor Li took out a 24 grenade and said a series of parameters, the bullet weighed 061kg, the warhead (charge part) weighed 017kg, the total length was 365, the charge type was TNT high explosive, and the detonation time was 4-5 seconds.

Instructor Li took out a smaller grenade and said: This kind of Gongxian imitation 24 grenade is equivalent to 2/3 of 24, and the weight is only 450 grams, about 70% of 24, which is in line with the arm strength and physical strength of Chinese soldiers, but the charge is only 50 grams, the explosion power is much smaller than that of 24, and the detonation time is about the same.

The advantages of the 24 grenade are many: first, because it has a long handle, it can be thrown far and accurately. Due to the principle of leverage, a soldier with basic training could throw it far and accurately. If you throw a bomb in a standing position, you can throw it 30~50 meters away, which is beyond the reach of other grenades.

Instructor Li took out a training bomb (it will not explode without explosives, and it is about the same size and weight as a real grenade), came to a standing position to throw the bomb, and threw it into the trench 40 meters away, which is already very powerful.

The second advantage is that in mountain warfare, especially when attacking from the back, a grenade without a handle is difficult to stand up when thrown up, and if it rolls down in a circle, it will hurt itself by mistake, while 24 will not.

Note: The U.S. military was in the Pacific theater, so there were many accidental injuries, and later the equipment was improved, and grenades were no longer used when attacking on the back.

24 The third advantage is that it can be used in a cluster; If a single grenade is not powerful enough to deal with some strong fortifications such as bunkers or tanks, cluster grenades can be used to solve the problem.

For example, tying several grenades together and sending them into the gun holes of the bunker with bamboo poles is equivalent to a bag of explosives. (Note: In the early days of the Anti-Japanese War, ** used cluster grenades to deal with Japanese tanks.) ）

However, the use of cluster grenades is only a helpless move due to the lack of explosive packs and the lack of remote delivery of bombs, and in fact, there are many problems; First of all, it can't be thrown far, several are tied together, it's heavy, and it can't be thrown far, what should I do? The only way to do this is to use a tragic human flesh bomb.

Secondly, the explosive effect of cluster grenades is not very good, and grenades mainly rely on fragments to kill and injure the enemy, which is more effective against group personnel targets, but very poor against buildings and armored targets.

The kind of scenes in movies and television where cluster grenades are thrown at enemy bunkers and tanks, and the enemy's bunkers and tanks explode and catch fire, is difficult in reality, after all, grenades do not have the same powerful firepower as explosive packs.

In addition, the time from the time of the fire to the explosion of each grenade will not be exactly the same, and when the first grenade of the cluster grenade explodes, the other grenades have not exploded, and they will be blown away from the place and exploded elsewhere.

If it is used to kill people, this is not a problem, but if it is used to blast the enemy's pillbox fortifications, blowing up the tank will disperse the explosive energy and will not achieve the purpose of blasting.

However, the transport of the 24 was relatively safe, because the detonator of the wooden-handled grenade had to be pulled and the string had to be pulled, and the safety pin of the grenade would explode once it was struck.

In terms of cost, 24 was cheap but time-consuming, and it took a lot of unnecessary man-hours to hollow out the wooden handle to accommodate the leads; In addition, the lead wire will be damaged by moisture in the wooden handle and will be pulled off.

Note: Later, in 1943, Germany improved the 43 on the basis of 24, in fact, it was a very simple transformation, that is, the lead was replaced in front of the bullet body, and there was no need to dig a hole in the wooden handle, which saved a lot of time and cost.

Instructor Li concluded that the grenade was very suitable for our country at that time, first, it was simple to manufacture and low in cost; Rather, it is simple to use, because the Chinese soldiers have a low level of education, and it takes longer to practice guns and artillery, and it is not necessarily good to use.

And the use of grenades, as long as you can throw stones, is fine, and the requirements for the user are minimal, as long as they are thrown at the enemy's position.

Note: During the entire Anti-Japanese War, the squadron used a total of more than 30 million grenades, most of which were 24 or imitations, and about 400,000 devils were killed and wounded on the grenades, which was the most feared melee weapon of the Japanese army in addition to the ZB-26 light machine gun.

Instructor Li is not in a hurry to teach everyone to throw bombs, or for the people of the three corps, except for the three dogs, who has not thrown grenades, not only on the training ground, but also on the battlefield, a lot of live ammunition has been thrown.

It's the three dogs, everything is fresh, but I'm embarrassed to say that I don't know, pick up a grenade and weigh it, it's quite heavy.

Looking at this almost two-pound thing, it is really not a simple matter to throw forty meters away, usually a two-three-two heavy stone, that is, a forty or fifty meters away.

And it is even more difficult to accurately throw this iron guy into the enemy's trench bunker thirty meters away, and it is not as simple as Instructor Li said, as long as he can throw stones.

Also, this is just a coach bomb, if it is a live bomb, after pulling the strings, the grenade in his hand is smoking, and it will explode at any time, killing himself, and the psychological pressure can be imagined.

You have to have a strong psychological quality, so that your hands will not be soft and trembling, and you dare to throw them with strength; In addition, in a state of war where bullets are flying everywhere and bombs are ringing everywhere, it is really a great courage to dare to expose one's body in order to throw a grenade.

This is really not a joke, you know, exposing the body to the enemy's gun, everyone knows what will happen and what the risks will be.
