However, at this time, Andrei did not know that in the future, he would rush to the Stalingrad theater to support, several new divisions to replenish the strength of the army are continuing training in the recruit training camps in Central Asia and Siberia, and a month and a half later, the first batch of support troops will leave for Stalingrad, and today will carry out grenade throwing training, grenade throwing training is a nightmare for many recruits, and I will always hear that recruits blow themselves up during throwing training, which is the reason for being too nervous, that is, the simplest and safest grenades will also appear in this situation, But such accidents are acceptable, as long as they don't happen often. Pen, fun, and www.biquge.info

Kuusinin, as an experienced engineer, of course, knew that the RGD-33 grenade shells of the Soviet army had a fuse that resembled a filter cigarette, which was put in by the thrower before use.

When throwing a grenade that is already in a ready state, hold the grip as much as possible with your hand, and then wave your arm to throw the grenade out.

This is determined by the special ignition mechanism of the bullet, when the whole grenade is pushed forward, the grip is held by the hand at this time, and the bullet body and the inner cylinder are free, the bullet body will drive the inner cylinder to move upward relative to the grip due to inertia, and the firing spring inside the grip is stretched at the same time, when the inertia force disappears, the firing spring of the projectile body and the inner cylinder is accelerated downward under the action of the firing spring in the grip, after the projectile body and the inner cylinder move in place, the firing pin in the firing pin seat fixed on the grip can just fire the fire cap in the fuse tube, and then ignite the delay drug, After a delay of about 3.5 seconds, the detonator and main charge were detonated.

The instantaneous process of this fire is generally completed in a short period of time after the grenade begins to exert force until it is shot, because it needs to rely on inertial force to complete the ignition process, so the force when throwing the bomb must be large and short, otherwise it will cause the inertia force of the projectile body to move and be insufficient, resulting in blind fire of the grenade.

On the other hand, the F-1 uses iron as its shell, which can be thrown to 30 to 45 meters in normal terms, and has an effective killing radius of about 30 meters [1]. The F-1 grenade contained 60 grams of trinitrotoluene (TNT) explosive, weighing 600 grams including the UZRGM fuse, which was also used in Soviet 2 and RGD-5 grenades, which detonated for 3.2 to 4 seconds.

After World War II, the Soviet Union began shipping large quantities of F-1 grenades and other weapons to several countries, including Iraq and other Arab regions, where imitations were also introduced. Although it has been discontinued, it is still present on the battlefield due to the large number of manufactures.

The biggest feature of the F-1 grenade is that it is powerful enough. Heavy enough, the F-1 uses cast iron as a shell and throws it at a distance of 30 to 45 meters under normal circumstances, and if the effective killing radius is 30 meters, it will blow itself up!!。 The F1 grenade is loaded with 60 grams of TNT explosives and weighs 600 grams with the UZRGM fuse, which has a detonation time of 3.2 to 4 seconds. After throwing the F1 grenade, you must lie on the ground honestly, or you will most likely be injured by your own grenade!

Complex operations will delay fighters, and front-line grenades are very important - the consumption of ammunition in large-scale wars is staggering, especially when the military-industrial system is destroyed, and it is necessary to provide troops with weapons that can be manufactured simply and quickly.

Kuusinin came up with the RGD-5, a small and light weight grenade with a long throwing distance, which has been the main equipment of the Soviet Union and the Warsaw Pact countries for many years after the end of World War II, and even in the eyes of later generations, it is a weapon with excellent performance.

The RGD-5 grenade is an oval-shaped handleless grenade, and the structure of the projectile body is simpler than that of the RG-42 grenade, consisting of two projectile bodies stamped into a semicircle. When the grenade is detonated, the huge kinetic energy generated by the 110gtnt explosive laid in the bomb body tears the bomb body apart, and at the same time, the bomb body is also driven by the explosive gas to burst out at a speed of hundreds of meters per second, producing a large number of effective killing fragments to kill the enemy's living targets around it.

RGD-5 has a low production cost (the unit price of each RGD-5 is only $5 now)... So this gadget was also quite common in war-torn areas in the future.

After the massive consumption of wooden-handled grenades on the battlefield, the Soviet army began the era of handleless grenades!

The instructor carefully taught his rabbit cubs before dropping the bomb, and he said: "This is the RGD-5 grenade, it is small and powerful, after opening the ring, throw it out for me, otherwise you little guys will wait to turn into meat sauce!" ”

After saying that, he pulled the grenade in his hand and threw it out! Bang, the dirt pit in the distance exploded, blowing up smoke and dust!

At the same time, it is necessary to train to dig trenches at night, but this is not difficult for the soldiers, most of the recruits recruited in Central Asia are from Kazakh collective farms, they often need to dig canals, and the rangers and hunters in the Siberian warriors also need to dig things, so the results of digging trenches are very satisfactory to the instructors!

At the same time, in countless gulags, more and more prisoners chose to join the army and go to the front, for them even to die at the hands of the Germans is better than to die in this blind wilderness!

How long does it take to train an ordinary lad into a relatively qualified military man?

By no means three months! After about a year of training, it may be possible to be regarded as relatively qualified and basically proficient in cultivating the military qualities that military personnel need to master and be ready to participate in war.

The losses of Soviet recruits in World War II were staggering. It was because they didn't know anything but how to use the rifle in their hand. It is dangerous for people who do not even know how to conduct coordinated operations at the squad and platoon level, who are not familiar with their comrades-in-arms, and who do not understand the army to participate in battles.

The training is still three months, but after the refinement of Andrei's program, climbing barbed wire and listening to machine guns in the trenches overhead, stabbing pigs and sheep, and so on.

Looking at these young boys, the instructors don't know how much they will survive in the future!

In fact, before the outbreak of the Soviet-German war, the "Soviet Association for the Promotion of National Defense and Aviation Chemical Construction" alone had more than 156,000 groups, 26,680 squads, and 3,500 squadrons throughout the country. More than 8,000 young people have been trained at the Aero Club, and more than 30,000 have learned how to fly gliders. But compared to the experienced German pilots, these pilots were only civil aviation pilots or aviation enthusiasts, they only knew how to fly airplanes and fire cannons, but they had no choice, and after a short period of training, they also had to go to the battlefield to fight the Nazi ace pilots!

Now that countless young men have left the factories, mines, and farmlands, and the women comrades have become the main force in many factories and mines, the comrades are working selflessly, and even the comrades who have retired and are too old to take part in farm work have spontaneously organized themselves to do what they can for the front line -- the old ladies have taken out their housekeeping skills in making boots, socks, and clothes, while the old men and women comrades have taken over all the tasks that the young men can replace in driving tractors, watering the fields, and cleaning the city.

All the city dwellers and farm members in the rear were enthusiastically donating their savings and valuables to the Soviets, and the comrades took out whatever was needed at the front, and the government offices at all levels had departments for receiving, counting, and diverting donated materials, money, and goods -- cash, state bonds, valuables, winter clothing, food, everything!

Now the whole country is mobilizing all its forces at full speed for the decisive battle at Stalingrad! And at the same time, the internal affairs department of the Far East received an urgent task!
