The smoke from the smoke bomb explosion still did not dissipate, but Lin Rui was able to determine the approximate location of the vehicle based on his hearing. The sound of the vehicle's engine, the footsteps of the infantry following the armored vehicles, and the collision of the weapons they carried. All gave him enough confidence. The only thing that made him unsure was his injured leg. He didn't know whether it could support his body.
The vehicle was getting closer, a slight tremor came from the roadside underfoot, and the engine roared. Lin Rui quickly poked his head out from the broken wall and took a look. The smoke outside was about to dissipate, and the Badger armored vehicle armed by the secret society gradually revealed its rigid lines. The vehicles and infantry did not notice him because Lin Rui was too close and became a blind spot of their attention. Everyone was paying attention to the enemy across the street, and no one thought that the enemy had already arrived at their side.
But it was precisely because he had gotten too close while taking advantage of the smoke that he couldn't fire now. Because the muzzle velocity of the rocket in his hand is 120ms. Since the launch overload causes the rocket's inertial delayed ignition mechanism to function, the powder delay insurance of the tail fuse must be opened when the rocket flies 10 to 14 meters out of the muzzle, and the rocket engine charge can be ignited.
"If a rocket is fired from a location less than ten meters away, even the fuse safety cannot be opened. The result may be that it hits the car body directly and then falls off. For an armored vehicle, it is almost like hitting it with a stone, causing no damage at all.
Because the electric-2 type piezoelectric fuze equipped with the 69-type 40 rocket launcher is divided into two mechanisms, the head and the tail. The head mechanism is the ignition energy source of the fuze and is mainly composed of ceramic piezoelectric crystals and circuits. When a rocket hits a tank, a high potential difference is generated at both ends of the crystal under the impact of the collision. This potential difference is connected to the electric detonator of the tail fuse through a wire. Like an electronic lighter, the electric detonator is detonated by an electric spark. Causes the warhead charge to explode.
The explosion wave pushes the cover body to form a metal jet, which penetrates the steel armor. The muzzle velocity of the rocket is 120ms. After the rocket flies 10 to 14m out of the muzzle, the rocket engine charge is ignited and accelerated due to inertia, and the rocket's speed reaches 295ms. In other words, to detonate a rocket normally, the warhead must move at a certain speed. This forced Lin Rui to keep a distance of more than fifteen meters from the armored vehicle.
Waiting silently for the vehicle to move forward, Lin Rui kept counting in his mind to estimate the distance and location. Finally he stood up suddenly and put the rocket launcher on his shoulders. A rocket shot out suddenly and hit the Badger armored vehicle more than thirty meters in front. There was a violent explosion, startling the armed men and fleeing in all directions. "There's an ambush!"
Lin Rui immediately squatted down, crawled quickly and moved in the other direction, bullets whizzing past his head. The trajectory of the rocket launcher can be easily judged. He is now a target and must leave here as soon as possible. A fragmentation grenade was thrown over. Lin Rui crouched down, rolled and hid in the corner with agility. "Boom!" The explosion of the fragmentation grenade made Lin Rui feel dizzy. He knew that if he hadn't seen the right moment and rolled into a blind corner, he would have been covered in shrapnel and bleeding profusely by now.
Lin Rui didn't dare to stay any longer, dragging his injured leg and moving as fast as possible. On the other side, Crazy Horse and other team members also destroyed another wheeled armor, which made the secret society's armed forces panic. Both wings were attacked at the same time, and the militants chose to retreat in unison.
Because this is an instinctive reaction of a commander. When you are moving forward, if you encounter enemies on both wings, the safest way is to retreat slightly to stabilize the situation. Because if you force a breakthrough regardless of the two wings, you are likely to be cut off by the enemy at your rear. This is a taboo when marching in complex terrain such as city streets. But their withdrawal also exposed a problem, exposing the self-propelled artillery supporting them from behind.
"It's the 2S19 self-propelled cannon. I saw it. It's a fucking big guy." Lin Rui pressed his earphones and gasped.
"I've seen it too. It's taller than ordinary tanks, and it looks bigger and bulkier." Ahu whispered, "Many secret society militants are retreating, and there are people around. It can't be fast. Move, I¡¯m trying to lock it in.¡±
Ahu was on the roof of a ruined building with another observer. He was carrying a launcher, which was their only Javelin missile. Because the Javelin missile is much more expensive than other anti-tank missiles, each missile alone costs more than 100,000 US dollars, not including the launch tube and aiming components. Even General Logan, who has deep pockets, cannot equip them in large quantities. This Javelin missile was assigned to them by General Kadom because he wanted to raid the enemy's artillery position last time. As a result, Lin Rui was reluctant to use it and has kept it until now.
This kind of Javelin missile is different from other anti-tank missiles. The Javelin anti-tank missile does not fly straight to the target and detonate after aiming at the target. Instead, it ejects out of the launch tube after aiming and locking the target. The ejection distance is about 10 meters.Then the missile engine ignites and adjusts its attitude, climbing vertically upward to a height of about 100 to 200 meters and then descending vertically. At the same time, the infrared guidance located at the front of the missile quickly finds and aims at the previously locked target, and then rushes towards the target at full speed to penetrate it at an extremely fast speed. And detonate the tank to complete the kill of the target. Some skilled veterans can even use Javelin anti-tank missiles to shoot down low-flying helicopters and other slower-flying, lower-altitude aircraft.
The top armor of ordinary tanks is relatively weak, and self-propelled artillery is even weaker. So although they only have one Javelin missile, it is enough to destroy the self-propelled artillery on the opposite side.
Lin Rui struggled a lot before taking out this missile for Ahu to use. He originally wanted Ahu to use a rocket launcher, because the Javelin missile could also be used to deal with helicopters. However, considering the distance and other unexpected factors, Lin Rui decided to hand over the Javelin missile to Ahu and let him complete the fatal blow.
"Hurry up, it's moving." Lin Rui said nervously, "Don't let it escape again!"
"I'm aiming and locking, this damn thermal imaging camera. Can't you hurry up! Okay, okay, I can do it, I've locked on the target!" Ahu shouted loudly. Following his roar, the transmitter he carried on his shoulder made a loud noise, and a ray of light suddenly flew into the sky, then suddenly accelerated and fell rapidly in the air, and the vague outline in the distance erupted with an earth-shattering explosion.
Ahu looked at the fire in the distance and cheered completely.
"Well done, the 2S19 self-propelled cannon was completely destroyed. You seemed to have detonated its ammunition rack, causing a devastating explosion." Lin Rui said loudly in the communication channel, "Okay, now notify everyone People retreated, but we continued to hold on.¡±
