rebirth of change

What was Chen Kangjie's reason for persuading McClellan?That is, the anti-aircraft missile used by the terrorists is the Sam-7. 【 】

萨姆—7是一种单兵肩扛便携式防空导弹，1966年开始在苏联军队列装，这套武器系统采用9m32式导弹，9p54式发射筒，9p53式击发结构和9p17式地面电源。

This weapon has many advantages. 1. It is light in weight, easy to carry, and convenient to transport. The total length is less than 1.5 meters and the weight is less than 15 kg. status, it only takes 2 seconds; 10, the cost is low, you can buy one for only 3 dollars at the most expensive time, and you can get it for hundreds of dollars when the price is low; 5000, the concealment and survivability are strong, and it can be carried by a single soldier Not easy to find.

它的有效杀伤半径6米，最大射程3400米，最大射高1 0米。它打击的主要目标是速度260米秒以下的喷气飞机、螺旋桨飞机和直升机。

Because of these characteristics of its own, this weapon has indeed shown its talents. It has achieved good results in the third Middle East War and the early Vietnam War, but it has become more and more unsatisfactory as it goes on. For example, in the two years from 1972 to 1974 , the North Vietnamese army used the Sam-7 to attack the fighter jets and helicopters of the US military, and the shooting rate was less than 5.00%.

This is because the Sam-7 also has a lot of flaws, mainly in: 1. The tracking ability is very general. The coordinate instrument of the Sam-7 uses a relatively backward lead sulfide thermal element as a tracking detection device. The working band is from 1000 to 7 microns. It has high sensitivity to high-temperature heat sources above [-] degrees Celsius. It can automatically and continuously measure the angle of the aircraft relative to the missile.This is terrible. The infrared seeker is not very sensitive. It only has a good tracking effect on the strong infrared radiation emitted by the tail of the jet plane, but it is basically unable to track other parts of the plane.In other words, the Sam-[-] can only pursue enemy planes from the tail, and cannot intercept them head-on.

2. The infrared seeker technology is backward and very vulnerable to interference.In fact, in the late Vietnam War, pilots of U.S. fixed-wing aircraft did not panic when they discovered that they were attacked by Sam 7. They only needed to release infrared decoy bombs immediately to ensure their own safety.This kind of jamming bomb can radiate strong infrared rays. As long as it is placed around the protected target, it can make the Sam-7 unable to distinguish the difference between the decoy bomb and the radiation of the aircraft itself.In fact, because Sam-7 has very poor discrimination ability.In actual combat, U.S. pilots don't even need to release the bait bombs they carry. Instead, they only need to change direction rapidly and fly towards the sun. The sun flew away.Even if there is no sun, the pilot only needs to dive the plane and then pull it up to avoid this kind of crude anti-aircraft weapon, but it is a little bit dangerous.

After Chen Kangjie brought up these reasons, he said to McClellan again, "Aren't the current aircraft not as good as before? Are your technology not as good as your predecessors during the Vietnam War? Don't you have confidence?".

Chen Kangjie is considered to be General McClellan's army.

"Hehe, it seems that I can't do it if I don't agree," McClellan said with a wry smile.

"It seems inappropriate to give you extra money. When you finish, I will use a business jet to take you and your family to and from Hawaii, and provide a week's hotel accommodation," Chen Kangjie said gratefully, patting McClellan on the shoulder.

"Okay, thank you in advance, I happen to be on vacation in Hawaii," McClellan replied happily.

. . . . . .

After returning to the airport for lunch and refueling the plane, the air battle scene officially began.

"This is Lyme 1. I saw three trucks on the east side of the bridge." McClellan drove the fighter plane alone and made a short parallel flight with Chen Kangjie and the others. For Chen Kangjie, the lines are not important, as long as there are images, the lines can be dubbed later.

As for the close-up of the pilot that will appear later, it was shot at the airport.

After the three fighters formed their formation, they began to roll sideways in an orderly manner at a distance of nearly 60 meters from Chen Kangjie and the others.

At this time, on a yacht on the sea, Luo Fuman was holding another camera and was taking upward shots. For safety reasons, they were still a little far away from the bridge, but the distance was shortened through the camera.At the front of the convoy, inside the back of a Toyota pickup, Jedica was ready to film the convoy moving forward and the bridge being blown up, while in the air, Carpenter was also working on another helicopter, his The task is to photograph the details of the target being attacked from the air.

The previous cars were all driving on the new bridge, and now the damage action is about to start, and the old sea-crossing bridge is on the north side of the new bridge. In order not to damage the new bridge, so in the next shooting process, the direction of the car It's the other way around, that is, the car is traveling from Marathon to Keywest.

After calculation, they first found a place far away from the two bridges, and Chen Kangjie and his two shooting helicopters hovered over the north side of the bridge.

"The convoy drove from east to west and arrived at the designated location in 2 minutes. McClellan, can you arrive on time in 2 minutes and fire the heavy machine gun on board?" Chen Kangjie contacted the fighter plane beside Cameron.

"No problem, can arrive on time".

"Your goal is to hit the truck in the middle with a heavy machine gun, remember, it's the one in the middle," Chen Kangjie continued to emphasize.

"Where are the people in the car? There will be no casualties, right?" McClellan was somewhat worried.

"There is no one in the car, the second car is being towed by the first car, it is empty, you can do something bold"

Sure enough, it only took 2 minutes for McClellan to fly the fighter plane in front of Chen Kangjie and the others. At this time, three trucks arrived just in time. To be on the safe side, only the first truck had a driver and two adjusted cameras. , the lenses of these two cameras are aimed at the truck in the middle that is about to be destroyed, and the two trucks behind are driven forward by it at a fixed speed.

For the purpose of being careful and making no big mistakes, the film crew applied to the state government to close this section of the bridge for an hour. If other vehicles choose to pass here at this time, they may be affected by Yuchi.

This film essentially reflects the positive image of the US military and intelligence agencies, so this not-so-excessive application was quickly approved and implemented.

"OK, go", after Chen Kangjie finished speaking, their shooting helicopter followed the fighter jets and swooped down. The bullets fired by the heavy machine guns under the wings sparked a fountain of water jets in the sea. Unfortunately, when the machine gun bullets When the truck on the bridge was paddled from the sea, it was shot empty, leaving only a row of deep bullet holes on the concrete floor of the bridge deck, and the huge shell casings were ejected and fell all the way into the sea.

"**", McClellan was a little annoyed at not concentrating on the target.

"Dude, it's okay, do it again", since he missed the hit, what can Chen Kangjie say, he can only appease him.

"Thank you, I'll fly back right away, and I'll be back in 2 minutes," McClellan said, letting the plane fly a 90° sideways flight at low altitude.

"We are waiting for you 800 meters to the west".

Helicopters can hover, and Harriers can also hover, but the truck team on the bridge can't stop at this time, they can only continue to drive forward, otherwise it will waste time, so they can only move westward to shoot again 800 meters.

"ok".

There were no more accidents in the second shooting. The truck in the middle was smashed by a row of heavy machine gun bullets, and various fragments and parts flew around. Finally, an explosion occurred directly on the bridge deck, and the raging fire blocked the entire bridge deck. , The thick smoke also rushed to a height of more than ten meters. Not only was this shot captured in the air, but the two cameras behind the first truck also faithfully recorded the clear process.

"Long, do you want to take a close-up shot of a truck rushing through the crowd and the thick smoke next?" Jedika on the ground asked Chen Kangjie via radio.

"Let's make up for that later. Shoot the next two shots directly. Terrorists use Sam-7 missiles to attack fighter jets and fighter jets to destroy the bridge. It's just a waste of a truck. If we don't finish shooting the aerial shots today, it will be a waste of time." It's time to reapply for the fighter plane," Chen Kangjie replied.

"Direct missile launch?".

"Yes, launch the missile directly. You make the Afghan actor get ready and ask him to deflect as far as possible. When you want to launch, remember to inform in advance, so that the helicopter can drop the jamming bomb."

Fighters can rely on their own functions to rely on this old individual anti-aircraft missile, but it is different for helicopters. This simple weapon is still a bit easy to deal with helicopters. At least the probability of being shot down is two or three times higher than fighter jets. Therefore, it is necessary to release jamming bombs in advance to be foolproof. I am on the plane. If I am hit, then I will dig my own grave.

"understand".

The convoy on the bridge stopped. It was impossible for them to launch missiles on the speeding truck. It would be too dangerous. Moreover, the launching location could only be in front of the burning truck.

At this time, there was only one fighter jet and one helicopter in the sky, and all other aircraft were moved forward to avoid being affected by the fish pond.The fighter jet is below the front, and the helicopter is above the rear. The distance between the two planes is 150 meters, and the distance between them and the bridge deck is more than 1000 meters.

"Long, it's ready, when will it start?" After getting ready, Jedica reported to Chen Kangjie.

"How is it, Lao Ka?" Chen Kangjie didn't answer Jedika, but asked Cameron beside him first.

"Hey, what else can I do? I'm already on your boat, and now I'm on the verge of breaking out," Cameron said depressingly.

Filming for Chen Kangjie was hard work, but the most important thing is that it was extremely dangerous. Now that he is facing a real attack from a surface-to-air missile, no matter how courageous Cameron is, if he says he is not guilty, he will be lying.

"Hehe, I'm not afraid at all, I'm with you too, don't worry, nothing will go wrong", in order for Cameron to stabilize his mood and take a good picture, Chen Kangjie had to say easily, in fact, he himself Also somewhat worried, this matter is not afraid of [-], just in case.
