Open an aircraft carrier to fight against Japan

The rules of this competition are as follows: each side sends out three tanks, only one tank goes into battle each time, and the starting line is 800 meters apart, whichever side's three tanks are destroyed first or withdraws from the battle will be considered a loser.

On Lin Yuan's side, Zhang Yun was the first to fight. Zhang Yun was very confident in the skills of his crew, and he didn't intend to let the two behind him fight. At this time, a Japanese soldier fired a red signal flare, and the two sides immediately dispatched and drove towards each other. go.

At this time, the driver had just fired and started the tank. Zhang Yun smiled and said to the gunner: "Do you believe it or not? We can win this first battle without firing the cannon!"

The gunner said in surprise: "You can win without firing? Company commander, you must be kidding me!"

Zhang Yun said with a smile: "What am I teasing you for, just wait, I will go out and win this first battle now." After Zhang Yun finished speaking, he pushed open the hatch, and the gunner said in surprise: "Company commander, you What are you going to do? You can't go out!"

The gunner was wondering when Zhang Yun got out of the tank, and then he heard the sound of a heavy machine gun. The gunner thought to himself: "What is the company commander doing? Do you want to use the heavy machine gun to penetrate the Japanese army?" How is this possible?" While the gunner was thinking, the sound of the heavy machine gun didn't stop for nearly a minute.

The gunfire finally stopped. At this time, the gunner saw Zhang Yun returning to the turret with a smile on his face, and said, "Okay, we won the first battle."

The gunner said in surprise: "We won? How is it possible? If we can defeat them with machine guns alone, we won't have to wait so long for armor-piercing shells!"

Zhang Yun said with a smile: "Just wait and see, the Japanese army will send out the signal that they have lost the first battle."

The gunner put his eyes on the scope suspiciously, and lowered the magnification of the scope to the lowest level. At this time, the scope is equivalent to an ordinary periscope that does not magnify the scene. The gunner turned the periscope and looked at Gao Po. A red flag was raised, which signaled the defeat of a Japanese tank.

It turns out that the people inside the tank have very few channels to obtain information from the outside world. First of all, the sound is impossible, because the tank is covered with a thick iron shell, and it is difficult for the sound to come in. This means that information cannot be transmitted by shouting, so we can only Rely on the periscope to observe the outside world.

The field of view of the tank's periscope is very narrow. The field of view of a person's eyes is about 135 degrees, and the field of view that can be seen most clearly is also 60 degrees. However, the field of view of the periscope of both tanks is less than 25 degrees, and the elevation angle is less than [-] degrees. That is to say, during the battle, it is impossible to transmit information through signal flares, so the two sides came up with the method of erecting flags on Gaopo to convey the victory and defeat information. When a Japanese tank failed, it erected a red flag. If a tank fails, a yellow flag is raised.

When the gunner saw that one of the Japanese tanks had failed, he couldn't help asking, "What's going on? How did you defeat them with a heavy machine gun?"

Zhang Yun laughed loudly and said: "We got the wreckage of the Japanese tank. After our research, we found that the sighting equipment of the Japanese army is relatively backward. The gunner does not have his own periscope with a large field of view. To find the target, he can only rely on The commander searches through the periscope, and tells the gunner the position of the target after the commander finds the target."

"The field of view of the Japanese tank commander's periscope is very small, only less than 23 degrees, while ours is [-] degrees. This means that we have a higher probability of finding enemy tanks. The Japanese commander must know that their tanks have a small search field of view. Therefore, they will definitely choose to go out of the cabin to observe, after all, they can use their eyes to search for the target after leaving the cabin, and the probability of finding the target will increase greatly.”

"I guessed this in advance, so I went outside the turret and used our heavy machine guns to shoot at the enemy. Although the tank looks like a small spot at a distance of 800 meters, our heavy machine guns fire fast, and the speed of fire is very fast. Faster means that there are many bullets flying near the enemy, and the probability of hitting is high."

"I used the maximum rate of fire to aim at the Japanese tank and fired almost all the [-] rounds of machine gun ammunition in the magazine. In this way, there was always one bullet that could hit the commander. I was lucky. I found out that the Japanese army The tank turned around and walked back, only then did I know that the commander of the Japanese army must have been shot dead by me, and the Japanese army knew that the battle would not be possible without the commander, so they withdrew from the battle."

The gunner gave a thumbs up and said, "You still have a solution, company commander! Can we use this method again?"

Zhang Yun said with a smile: "Are you a fool when you're a little devil? With this lesson, their commanders will never dare to show their turrets again."

At this time, Masaichi Kumamoto also heard the reason for his failure, and his face was pale with anger, but he had no choice but to ask the tankers behind to pay attention not to expose his body outside the vehicle.

The second Japanese tank learned this lesson resolutely. Once the tank came out, the commander stayed in the turret. In this case, he could only use the periscope to search for the target. Zhang Yun did the same. He put his eyes on the Zhou style periscope. On the eyepiece, the objective lens was turned to search for the Japanese tank. At this time, the advantage of the large field of view was reflected. Zhang Yun spotted the Japanese tank first, so he said to the gunner: "The target is at one o'clock."

The gunner immediately turned the main gun and aimed at the direction of one o'clock. At this time, the Japanese tank had not found Zhang Yun's tank and was still moving in the original direction. The gunner next to Zhang Yun finished aiming and said immediately: "Stop!" The driver stopped the tank immediately, and the gunner pressed the laser launch button of the laser range finder during the stop, and a laser beam hit the Japanese tank and returned, and the distance immediately appeared on the screen, 873 meters!

The gunner operated the artillery, and pressed the muzzle firmly on the path of the Japanese tank. At this time, the Japanese tank also spotted Zhang Yun's tank. The commander saw that Zhang Yun's tank had stopped, and the muzzle was still following his own. The tank moved slowly, and was taken aback immediately, thinking: "The Chinese's main artillery tank has already aimed at us, will they hit us? We must dodge this shot, and the Chinese gunner on the opposite side must have calculated ahead of time." As long as we change direction immediately, they won't be able to hit us!"

Thinking of this, the Japanese commander immediately ordered: "Driver, change direction, hurry up!"

The driver instinctively asked, "Which way to change direction?"

The driver yelled, "Anywhere is fine! Hurry up!"

The driver also understood what happened at this time: the main gun of the Chinese tank had already aimed at them, and if he didn't turn around, he would definitely be hit. The driver hurriedly turned to the right, but the extremely poor mobility of the Japanese tank killed them. They, the huge tank delayed for a second before turning around. At this moment, the gunner next to Zhang Yun pressed the firing button, and an armor-piercing shell flew out of the gun barrel, and went straight to the Japanese tank.

The commander of the Japanese army had been staring at Zhang Yun’s tank all the time. Seeing the muzzle flash of Zhang Yun’s tank, his heart felt cold, and he thought: “It’s broken, they’re firing! God bless you, please don’t shoot it!” Hit us!"
