Wearing a bathrobe, Xia Lingyun saw Cortana sitting on the sofa, and poked her finger curiously and said: "This virtual image looks quite realistic, maybe it can project a fake target to confuse the enemy in the future." ”

Wang Zhiyuan brought out his innovative dinner, the canned hillbilly egg beef stew, and said: "Come on~taste~ my new hillbilly beef stew." ”

Xia Lingyun frowned, stretched her nose in front of the rice bowl, sniffed it and said, "How many times have you succeeded in the dark cuisine that you have been on a whim these days?" This time, although it is as unsightly as ever, it smells okay. ”

Cortana watched the two of them finish their miserable dinner, opened the recycling list and said, "Master Chief ~ found more than a dozen Type 15 automatic rifles, do you want to throw them away?" Wang Zhiyuan glanced at it and said, "It's basically useless, let Ka grab himself and leave another empty ammunition box and put it on the back roof of the ambulance." ”

After dinner, Wang Zhiyuan seriously reflected on the experience of the past two days, and felt that the lack of armor-piercing bullets was a huge problem, so he opened the computer in the driver's seat that had been occupied by Cortana for a long time to retrieve the armor-piercing bullet information.

It took more than an hour to watch it, and Wang Zhiyuan roughly summed it up: "Not to mention the types of bullets that are too backward, there are only a few commonly used in the world of chariots, and most of the actual combat effects have been more or less understood in various games and documentaries." ”

APCR-hard-core armor-piercing projectile, given that under the same kinetic energy, the smaller the force surface, the more concentrated the kinetic energy, and therefore the better the armor-piercing effect.

APDS - Shell-Piercing Shell: The difference with APCR is that after it comes out of the barrel, the armor-piercing core is separated from the warhead to achieve less wind resistance and higher velocity. Anyway, the armor-piercing ability is higher, but the damage is just as touching.

APFSDS - shelled tail stabilized armor-piercing projectile: The tail is added on the basis of APDS, the flight is more stable, and it is goodbye to rifled guns. None of these three aperture series can be loaded with explosives.

HE-High Explosive Shells: This thing is not primarily designed to target highly armored targets. But in modern times, basically as long as it is a cannon, how many rounds will be carried, and the bunker will be dismantled? No problem, tear the infantry? No problem, bug fighting? One shot is basically dead. The principle is crude and simple, similar to a grenade, relying on explosion waves and projectile fragments to kill. But it doesn't work well on tanks, especially modern tanks that seal well.

HEAT-Armor-piercing projectile: It is completely unaffected by the muzzle velocity and distance of the shell, and the metal jet that relies on the blasting of the shell itself to shoot through the tank, is the lethality.... Depending on the situation, the armor-piercing ability is strong, but the thicker the armor, the worse the effect. This is almost always the case with individual anti-tank weapons, but if the tank has a skirt or reactive armor or something like that, it's GG.

HESH-Armor Fragmentation: The Patent of the Rotten Nation. Rifled cannons fired, so the Rotten Nation is now almost the only military boss who still supplies rifled cannons. Actually, it's a bit similar to HE, but if you hit the blast in a certain area of the armor, the armor inside the collapsed tank will be killed. Someone once asked if he could kill the driver inside if he didn't penetrate the tank? This kind of bullet can.

High-explosive shells have proven to be very ineffective against modern main battle tanks, and three shots do not necessarily make the opponent ineffective.

Considering that the turret ammo rack can only hold 14 shells, plus 1 breech is a maximum of 15 shells, the ammunition type requires a high degree of target compatibility, which can hit both heavy armored vehicles and large creatures.

Those sub-caliber bullets are obviously not suitable as commonly used bullets, and you can only do some experiments on armor-piercing bullets and armor-shattering bullets to see the effect.

An anti-tank rocket was dismantled in the ammunition stacking module, and the principle used was basically that the metal jet broke the armor and stopped the 150 mm main gun ammunition stacking process.

The data of the anti-tank rocket warhead is magnified in equal proportions into the tank shell, and the 150-mm anti-tank rocket launcher is buzzing in the brain.

Armor fragmentation bullets are only popular among people in Y country, and the principle is not too complicated, probably a soft metal warhead, which is flattened and then detonated when it touches the armor surface.

By clinging to the blast wave of the explosion and shattering the tank's internals, it sounds like it would be more effective to hit a large thick beetle.

In line with the idea of experimenting to find out the truth, Wang Zhiyuan tried to make 3 of them and added them to the list of the process of the ammunition stacking module, thinking that as long as the effect of the HE grenade was successful.

After confirming all the repair process, Wang Zhiyuan looked back, Xia Lingyun walked out of the maintenance compartment next door with the Type 29 anti-materiel sniper rifle that had never been used.

Looking at her suffocated red neck, Wang Zhiyuan turned sideways and said with a smile: "Why did you come out with such a heavy thing?" Xia Lingyun stood the gun at his feet and said word by word: "This sniper rifle will be mine~"

Wang Zhiyuan nodded and said: "Okay~ Anyway, my marksmanship is not good, I remember you said that you have won a shooting championship before, and you just used it to the fullest." ”

Holding the gun on his shoulder, he walked up to Wang Zhiyuan and stretched out his small hand and said, "Bullet~?" I want bullets ~ at least 5 magazines of 10 rounds. ”

Putting down the cup in his hand, Wang Zhiyuan walked to the weapon rack in the maintenance compartment. She opened the cabinet underneath and took out 10 magazines, then took a Dragon SVD semi-automatic sniper rifle from the shelf and gave her a single cartridge of ammunition.

Wang Zhiyuan spread his hands and said, "It's all happy for you, right?" That thing is too heavy to play, if you really want to carry it out and encounter danger, you can only throw it away and run for your life, and those cool operations in the movie game are basically~"

Xia Lingyun said with some grievances: "Although we haven't been together for a long time, you have always been very serious about protecting me." I never let me take the slightest risk by eating and drinking for nothing with you, but now I want to use my strength to help you in this situation. ”

Looking at her somewhat red eyes, Wang Zhiyuan smiled and said: "The gun and bullets are given to you, look at ~ Why are you still crying, aiming has a night vision mode, just when you come to try the gun to soothe your mood." ”

The two opened the skylight of the RV bedroom, the orange sunset hung on the mountains in the distance, Wang Zhiyuan compared it with his finger and said: "It will be dark in less than two hours, hurry up and find the target and shoot a few shots." ”

Soon Wang Zhiyuan took the telescope and saw that there was a one-meter-sized spider crawling on the street lamp at the foot of the street in the west, and he turned on the ranging mode to see 800 meters.

Wang Zhiyuan grabbed the dust on the roof of the car and dispersed a little and said: "It's that unlucky guy, the wind direction is southerly and gentle at 800 meters, so it shouldn't be a big problem." ”

Xia Lingyun didn't like to open the tripod on the roof of the car, leaned on the roof of the car and slowly pulled the bolt, holding her breath and slowly pressing the trigger with her index finger. With a loud bang, the muzzle of the gun rolled up a large piece of sand, and bullets whistled out.

In the binoculars, the bullet missed a little and hit just in time, and the spider's hairy ribcage opened a fist-sized hole in the chest. The lamppost, splashed with green slime, was also cut deep by the bullet.

After running out of 2 magazines and basically beating up all the infected creatures that could be seen around the block, Wang Zhiyuan looked at Xia Lingyun, who was gray-faced, and said: "You have provoked all the surroundings, now do we two terracotta warriors have to go back to take a mandarin duck bath?" ”
