In addition to the powerful mortars, the Japanese army also has a more headache, that is, the grenadier canister, Tang Chengliang from the 89th Division knows very well, because the 89th Division and the Japanese army fought the Great Wall War of Resistance a few years ago.

Ryoko heard from the veteran that the bombs from the devil's grenadier were the same as raindrops, shining on the light and heavy machine gun positions, and kept falling, and in less than a while, the heavy machine guns were basically dumb, and the light machine guns had to shoot a few shots to change places in order to survive.

Lao Hei also survived the War of Resistance on the Great Wall, so he naturally knew the Japanese army's combat methods very well, so although the troops of the national army were rarely equipped with grenadiers, everyone still had to understand and learn this "weird" weapon.

Lao Hei brought a grenadier canister, which was an imitation of the Japanese Taisho ten-year style, which was as long as a half-barrel and had a special projectile, similar to the Japanese grenade.

The grenadier is similar to a small mortar, when firing, the firing rod is first pulled, then the ammunition is loaded from the barrel opening, the canister is held, and after a rough aiming through the aiming line, the belt on the firing machine is pulled, and the grenade is fired with the bottom of the firing explosive.

Since the angle of the grenadier is adjusted to determine the firing distance and aim at the target, only an experienced grenadier can accurately hit the target.

The grenadier has a large angle of fire and a curved trajectory, although the range is not far, it has a good killing effect, is easy to operate, can be carried by a single soldier and can be launched behind obstacles, and the concealment is very strong.

There are so many advantages, Lao Hei said, as long as you can use or have used it, you think it is very easy to use, for infantry, you don't have to risk standing up and throwing grenades, it is simply a bomb throwing weapon.

However, the range of the grenadier that copied the 10th year of Taisho was too short, only more than 100 meters, less than 200 meters, and it was dangerous to use it at a distance.

Within 200 meters, the enemy's rifle machine guns can be covered by fire, and even pistol shell guns can be attacked.

Later, the Japanese army changed to the eight-nine type, the caliber remained unchanged or 50 mm, and it would be a little heavier, that is, four or five pounds, which didn't matter to the infantry.

But its range is much better, the maximum range is 700 meters, the effective range is 500 meters, and at 500 meters away, basically except for machine guns, the power of hand rifles is much less, relatively speaking, it is very safe for the launcher.

Note: In 1938, the National Army also imitated a new grenadier in accordance with the tenth year of Taisho, called the 27th year of the Republic of China; However, the range is only 250 meters, which is 100 meters farther than the Taisho 10-type type, but far less than the 500-meter range of the 89-type type.

Even so, the national army still produced a lot of these simple and low-cost grenadiers to equip the troops, although they could not do the 89 type, but still made up for the serious shortage of the national army in artillery, and were deeply loved by the grassroots soldiers of the national army.

It was not until the appearance of the grenade that the grenadier slowly withdrew from the stage of history, and as a unique weapon in the East Asian theater during World War II, it was not paid much attention.

……

Therefore, in principle, the grenadier is an ultra-light mortar, which is used to kill and injure the enemy hiding behind fortifications and concealments or to kill and injure the enemy's living forces at a long distance, and its killing effect is good and easy to operate.

The grenadiers are carried by special ammunition bags, one of which can carry eight grenades, and a two-person grenadier group of 16.

If you train properly, you can hit 80 to 90 percent within 200 meters in actual combat, which is more accurate than throwing grenades, and you can attack from a distance of several hundred meters.

Lao Hei played a few hands to show everyone, basically two or three rounds can get rid of a light and heavy machine gun fire point, once the machine gun fire is destroyed, you can immediately organize your own light and heavy machine guns to suppress the opponent's firepower, and then launch a charge with superior forces.

For example, in defensive operations, grenadiers and machine gun fire can be used to coordinate the enemy's charge, first suppress the enemy's charge with machine gun fire, and then use the grenadier to kill the enemy at a distance of the opponent's grenade.

If the enemy gets up, he will be killed by machine gun fire, and if he leans down to hide, he will be killed by grenadiers. The radius of destruction of the fragmentation of a grenade grenade can reach 8-10 meters, which is much better than that of a grenade.

The grenadier is very lethal to infantry and machine-gun fire points that are not protected by strong bunkers, but it is not very useful for bunker pillboxes with permanent or semi-permanent fortifications.

So how do you get rid of bunker bunkers? Lao Hei asked everyone. For the infantry, it can only be said that the movement was blown up with explosives after approaching, but the casualties during the movement were very large, and it was difficult to pass the death distance of four or five hundred meters.

"Bombard it directly with a cannon." Da Biao said.

"With such a good treatment, then everyone is willing to be an infantryman, but the problem is that our artillery is very few, most of them are bought with money, and the cannonballs are fired one less shot, and the cannons can not be used casually." Lao Hei said helplessly.

"There are not many cannons, and there are still some small cannons, if there is an emergency and important stronghold, small cannons can be used to support the infantry."

What are the small cannons? Mainly 75 mountain artillery and 70 infantry artillery, that thing can only be used by units above the division level, there are many miscellaneous troops, and it is estimated that there are not many at the army level.

However, the Japanese army was very generous, with four to six 92-type 70 infantry guns equipped to the brigade level (almost battalion level), not including the field artillery wing of each standing division and regiment, equipped with nearly 100 75-150 mountain artillery, cannons, howitzers, etc.

The Japanese army also has tanks and fighting vehicles, these things are deadly super weapons for the infantry, Cao Zeyuan of the tank battalion is very clear, although he is the infantry of the tank battalion, with the combat of the tank, but also knows that the destructive power of the tank tank is a nightmare for the infantry.

In fact, tanks and permanent fortifications also have a nemesis, that is, artillery is close to direct shooting, artillery is expensive, mountain artillery infantry artillery is also fine, and no matter how bad the 37 battle defense artillery can be.

BUT THE PROBLEM IS THAT EVEN THE 37MM BATTLE DEFENSE ARTILLERY IS VERY LITTLE EQUIPPED BY THE NATIONAL ARMY, AND THIS KIND OF ARTILLERY IS ONLY EQUIPPED WITH A SMALL NUMBER OF THE DESCENDANTS IN THE DESCENDANT TROOPS, AND THE OTHER ORDINARY TROOPS DO NOT EVEN HAVE A SHADOW.

Lao Hei took everyone to visit the only 37 gun in the military academy, which was just imported from Germany, PaK battle defense gun, small in size, 1.66 meters long barrel, 1.65 meters wide, 1.17 meters high, only 450 kg in marching weight, 4 soldiers can also push it around.

The rate of fire of the 37 gun is 13 rounds / min, the muzzle velocity is 762 m / s, and the effective firing range is 300-600 m; When dealing with tanks, armor-piercing shells can penetrate 34 mm thick homogeneous steel armor at a distance of 100 meters, and armor-piercing capacity of 29 mm at a distance of 500 meters, which is more than enough to deal with Japanese tanks.

The thickest armor tank of the Japanese army in China is only 25 mm, the armor thickness of the common Type 89 tank is only 17 mm, and the armor thickness of the Type 94 and Type 95 light tanks is only 6-12 mm.

But in addition to the lack of resources, people are reluctant to make such thick steel plates, and another point is to bully us China, there is no artillery.

It can be seen that a country's war mainly relies on industry and the military industry, and the backwardness of the country, especially the backwardness of the military industry, means that it will be beaten.

If the military industry is developed, like Japan, and it can build its own aircraft, artillery, and tanks, there will be no need to use soldiers to fill those bloody holes, or the enemy will not dare to come to the door easily.

Lao Hei, who participated in the bloody battle of the Great Wall, couldn't help but feel a lot of feelings, of course, these words would not be said to this group of students, nor could they be said to the outside.

I have to look at this group of energetic students with pity, after they graduate, they will normally fight against the Japanese army, and when the time comes, how many will survive?
