Chapter 2621: Laser rangefinder

When the armored unit is moving in the desert, the movement is quite large. This is not only the black smoke coming out of the exhaust pipe when the tank is moving, but also the tank unit when it is moving. The yellow sand that stirs the ground is like a galloping horse, and the scene is quite magnificent.
Only during the World War, such large-scale battles of tanks on land often appeared. Now, it is rarely seen. Even when the two camps face off, both sides have deployed a large number of tanks. I have never seen a real battle, just the magnificent momentum on the exercise field.
Now, the battle is finally about to begin.
After shouting this sentence, Blair hurriedly threw away his cigarette and lighter, then closed the hatch and returned to the inside of his tank. At this time, the commander had passed the commander's peripheral sight and began to look forward. Maximum magnification!
The scene in front gradually became clear. The commander saw the angular turret of the tank on the opposite side. The long barrel in front of the turret immediately recognized it.
"Attention, shelling armor-piercing bullet! M833!" the captain shouted loudly.
Eagle country’s tanks don’t seem to attach much importance to the research and development of tank guns. They prefer to use doctrine. The current 105mm tank gun is the L7 standard tank gun in the entire camp. The advantage of this gun is that everyone’s shells can be used. Versatile, minimizing dependence on logistics supplies.
Although the artillery is the same, the Eagles have developed a series of advanced artillery shells, so the power has also been greatly improved.
When this tank gun was in service, they were first equipped with M735 shelling armor-piercing shells. Because they disliked that the power of this shell was not strong enough, they quickly developed their own M774 and M833 stabilized shell armor-piercing shells. They are all depleted uranium warheads, especially the M833 armor-piercing projectile at the back. The performance is quite advanced, with a penetration depth of 440 mm at 2000 meters!
At present, the armor data of various countries are confidential, but similar to the T-72, the first armor is not 400 mm thick, that is, after the explosive reaction armor is carried, the protection power is slightly increased. This kind of shell can easily tear apart the armor of the bear country's main battle tank, and it is still at a distance of two kilometers!
Due to the problem of the fire control system, the actual direct aiming distance of Xiong's tanks is not far. If the training of operating the tank is not rich enough, the fire control system is often not even used, and the launch data is bound directly by feeling.
The West is different. The West has advanced fire control systems, and what they pursue is to strike at the enemy from a long distance.
Now, following the command of the commander, Blair quickly drew an armor-piercing projectile from the back, banged it into the barrel, and shouted loudly: "Loading finished!"
The human flesh filling machine began his intense and efficient work.
The captain continued to aim at the opponent, and then activated the laser rangefinder. A thin laser beam flew from here to the tank on the opposite side. For the speed of light, this distance almost takes no time. When you come back in the past, you can measure the distance accurately.
You know, measuring the distance is the first step in an accurate attack. If you don't know the distance value, then you can't fight. After all, the trajectory of the shells is still curved, even if it is relatively small.
In the previous era, one could only rely on experience. Specifically, according to the principle of perspective, the width of the enemy’s tank was measured on one's sight, and then compared with the actual width. According to the proportional relationship, the two sides were calculated. distance.
This requires the captain to have strong mental arithmetic capabilities and to be able to carry the width data of all tanks.
There is no need now. A laser beam passes over and everything is done. Not to mention tanks. Many aircraft use laser rangefinders to measure distances when they first start using missiles.
The captain was waiting for the laser rangefinder to return the measurement results, but he was disappointed. His laser rangefinder actually failed. What's the matter?
Of course he didn't know what was going on. At this time, on the opposite tank, a mushroom head was specially installed on the top of each tank's turret. This device was used to interfere with the laser from the opposite side.
If you want to suppress and kill the opponent's laser rangefinder, it is not possible for the time being, but it is no problem to interfere with them. At the same time, this can also send a warning that the opponent is preparing to do it.
The fat armor Ali got into his turret, watching the battlefield in front of him, his face was calm and confident: "Attention, the distance is two kilometers, give me a shot, and then retreat!"
If it is other tanks, even the bear country’s T-72, the first hit rate is quite poor at a distance of one kilometer. However, their tank, the most powerful 79 tank, and the advanced fire control system can guarantee They have a very high long-range starting rate, and their battle will not be a swarm of forward attacks.
In Armor Ali's hands, he also held the armored soldier training textbook. This tutorial obtained from Han has become their magic weapon.
The laser rangefinders fired laser beams toward the opposite side one after another, quickly returning the results.
Two thousand five hundred meters, two thousand three hundred meters, two thousand one hundred meters, two thousand meters!
"Stop and fire!"
In fact, Han Guo's fire control system has long achieved two-way stability and has the ability to fire on the move. But now, in order to pursue absolute accuracy in the first round, they still choose to stop, and they should retreat as planned. Yes, of course I have to take advantage of this gap to open fire.
The gun barrel was aimed at the opponent, and the semi-automatic loader easily loaded the shells. After receiving the command from the commander, the gunner slammed the firing device of the artillery.
"Boom!" A huge roar sounded, and the entire tank sat backwards. At the muzzle, a ball of flame emerged. A 120mm tungsten alloy armor-piercing projectile was thrown away, the tail was deployed, and forward. flight.
This is also the most advanced armor-piercing bullet imported from Han!
If you want an armor-piercing projectile to have excellent penetration ability, you must have a high enough muzzle velocity. This type of 50-caliber 120mm tank gun has a longer barrel, which greatly increases the speed at which the gun ejects from the muzzle. At the same time, the shell After repeated processing, the aspect ratio has reached a limit number. All of these have greatly improved its breakdown ability!
The specific theoretical values ​​are purely theoretical. Now, in actual combat, they are preparing to create such a miracle, attacking the tanks of Eagle Nation from a long distance, and let them taste the power of their own armor-piercing projectiles!
