Wang Xuexin was actually not surprised by this test result.
This is also one of the benefits of not using hollow charges.
It’s not that Wang Xuexin doesn’t have hollow charging technology, he can just earn some military industry coins and buy it from the system.
But some troubles will inevitably arise after using hollow charge technology... Hollow charge relies on metal jets to penetrate target armor. It has a problem that is difficult to solve: the fuze detonation distance.
After the warhead hits the target, if the detonation distance is too long, the path of the metal jet will be too long, which will cause the jet to not be concentrated and dispersed, resulting in poor armor-piercing effect.
If the detonation distance is too short, the metal jets will not have time to converge together to form a high-temperature and high-pressure jet, and the armor-piercing effect will also be poor.
This is a bit like a concave mirror focusing sunlight. The anti-conical shape of the hollow charge also focuses the metal jet. It will not work if it does not reach or exceed this focus.
Therefore, this armor-piercing projectile must be equipped with a special, particularly sensitive fuze: a piezoelectric ceramic instantaneous explosion fuze.
This kind of fuze can detonate with a reaction time of one hundred thousandth of a second when the warhead reaches a certain pressure after hitting the target, that is, when it reaches the focal distance.
However, the problem that comes with it is that it does not explode when it hits the ground, does not explode when hitting a soft target, etc... Insufficient pressure will be defaulted to not reaching the most suitable focus distance.
Therefore, the use of spring mattresses to block RPGs in the movie Wolf Warrior is actually a real reaction. This kind of fuze will not explode even if it hits a soft target. (If it is a grenade head that kills infantry, it is another matter.)
The rocket launcher that Wang Xuexin designed is simple and uses an ordinary fuse. It will explode as soon as it is touched, no matter what it hits, so there are not so many problems.
Anyway, there are enough tanks to deal with the Japs, so why bother to make it so complicated?
Isn't it superfluous to make things complicated?
What is the difference between a Japanese tank that can penetrate 100mm and a Japanese tank that can penetrate 15mm and shoot 12mm?
The simpler something is, the higher its reliability is. At this time, what the Eighth Route Army wants is simplicity, safety, and reliability. These are more important than anything else!
As for the Japanese medium tanks and heavy tanks, let alone the small number of the Japanese, their medium and heavy tanks actually correspond to the international light and medium tanks, and their side and rear armor are still only a dozen millimeters.
If it doesn't work, just replace the black powder with more powerful smokeless powder!
Therefore, Wang Xuexin considered more tactics that matched the rocket launcher.
"Chief!" Wang Xuexin replied: "If the Japanese are well prepared, it will be difficult for us to charge towards the Japanese tanks and rush 150 meters, so I was wondering if we could retreat to advance!"
Japanese tanks are not just tanks. They are usually covered by infantry. It is not easy to attack a hundred meters.
"Retreat to advance?" The leader was very interested in this. He thought about it and said, "You mean... let the Japanese charge?"
"That's right!" Wang Xuexin nodded and said: "That's what I mean. If we encounter the enemy on the plains, with the firepower of our army, we will definitely not be able to charge against the enemy. At that time, our army should take a defensive position and build fortifications on the spot!
"
This is actually a regular tactic of the Eighth Route Army, but in the past it was not proactive but was forced to take the defensive... No way, the equipment is not as good as the enemy. If they take the initiative to attack in plain areas, such troops basically do not exist.
Hearing this, the leader seemed to understand. He nodded and said thoughtfully: "Then... when the enemy launched an attack, we took the initiative to retreat. Before retreating, we left the rocket launcher shooter behind to ambush the Japanese!
"
As he spoke, the commander became happy: "That's a good idea. A range of more than a hundred meters is enough! It's best to put out more smoke, retract your fist a little and then hit it out, so that the Japanese can be hurt!"
The chief is worthy of being a chief. Wang Xuexin just made the beginning, and he had to guess everything that followed.
Wang Xuexin indeed had this idea.
The chief didn't explain it clearly, but it became clear after a comparison:
To take the initiative to attack, you need to charge with a rocket launcher. The target is too big, and the rocket launcher plus rockets are not light enough. The leap speed cannot be fast, and it is easy for the enemy to use it as a target.
But it's different if we take a defensive position. The combat troops hold the enemy for a while and let the bazooka shooters build individual bunkers or directly find a crater or something to hide themselves like spreading beans.
Then the combat troops retreated while fighting. If the Japanese rushed forward, they would fall directly into the ambush area of the rocket launcher!
Wang Xuexin had originally prepared a lot of words, but he didn't expect that he was finished by the chief in a few seconds. He even added smoke...
This smoke is great!
Not only can it interfere with the sight of enemy tanks, but it can also provide cover for rocket launcher shooters, killing two birds with one stone.
The chief of staff also understood. He thought for a moment and then raised an objection: "Chief, what if the Japanese infantry moves past the tanks to search and advance? Our rocket launchers are not enough to defeat the Japanese infantry!"
What this means is that the Japanese are not fools. They usually do not let tanks drive at the front, but use infantry in the front to clear roads and break obstacles.
At that time, the bazooka shooters will be fighting against the Japanese rifles and bayonets.
The chief didn't have a good idea about this either. He frowned and turned his attention to Wang Xuexin.
Of course Wang Xuexin had thought about this problem, and he replied without thinking: "Chief, Chief of Staff, I think this problem requires the cooperation of three parties. The first is the rapid deployment of bullet mines to delay the Japanese infantry!"
"That's right!" The leader agreed: "When the combat troops retreat, they can leave a batch of bullets and mines. The Japanese infantry is blocked but the tanks are not affected, so the tanks move forward!"
Wang Xuexin added: "Secondly, our combat troops can attract the enemy's firepower and attention, and consciously protect our rocket launcher shooters!"
"It makes sense!" The chief nodded slightly: "Our guns with original bullets can also shoot far, and we also have 50 small guns, which also have a range of 500 meters. Taking a step back can also provide cover for the front!"
Then the leader looked at Wang Xuexin strangely: "You have already talked about the underground and the ground. What else can the third aspect be? Could it be the sky?"
Wang Xuexin replied with a smile: "How can it be the sky? But it's almost the same! We can also use a rocket launcher to hit infantry, right? It's true that the rocket launcher has no grooves and less fragments, but we can stuff balls inside!"
Wang Xuexin couldn't hold back his words: "We will use small rolling balls and stuff hundreds of them inside at one go. When we see the Japanese infantry coming up, we will use this warhead to hit them. With a 'chirp' sound, that guy is not good at all."
Where did a big piece fall?"
The leader was stunned for a long time as he listened. After a while, he turned his attention to Zhang Wanhe and said, "Old Zhang, this guy is good! He is a weapons expert!"
