What is the reason why Chen Kangjie convinced McClellan? It is that the air defense missile used by the terrorists is Sam, 7.

Sam,7 is a single-soldier portable air defense missile that was installed in the Soviet army in 1966. This weapon system uses a 9M32 missile, a 9P54 launch cylinder, a 9P53 firing structure and a 9P17 ground power supply.

This weapon has many advantages: 1. It is lightweight, easy to carry, and convenient to transport. It is less than 1.5 meters long and weighs only 15 kilograms; 2. It is easy to operate and easy to learn. It is usually used by people reading the manual. It only takes 10 seconds from the loading state to the launch state; 3. It is cheap. When it is the most expensive, you can buy one for only 5,000 US dollars. When it is low, you can get it for a few hundred dollars. 4. It has strong concealment and survivability, and it is difficult to find it if it is carried by a single soldier.

Its effective killing radius is 6 meters, its maximum range is 3,400 meters, and its maximum shooting height is 1,200 meters. Its main targets are jets, propellers and helicopters with speeds below 260 meters per second.

Because of these characteristics, this weapon has indeed shown its strengths. It achieved good results in the Third Middle East War and the Vietnam War, but the more it went on, it became less satisfactory. For example, in the two years from 1972 to 1974, the North Vietnamese army used Sam to attack US fighter jets and helicopters, with a shooting down rate of less than 5%.

This is because Sam 7 also has great defects, mainly manifested in: 1. The tracking ability is very average. Sam 7's coordinate instrument uses relatively backward lead sulfide thermal elements as the tracking and detection device. Its working band is 1.8 to 2.9 microns, and it has a high sensitivity to high-temperature heat sources above 1,000 degrees Celsius. It can automatically and continuously measure the angle of the aircraft relative to the missile. This is very fatal. The infrared seeker is not sensitive and only has a good tracking effect on the detection of strong infrared radiation discharged from the tail of the jet aircraft. However, it is basically impossible to track other parts of the aircraft. In other words, Sam 7 can only pursue enemy aircraft from the tail and cannot intercept head-on.

2. The infrared seeker technology is backward and is very easy to be disturbed. In fact, in the late Vietnam War, pilots of US fixed-wing aircraft were not panicked when they found that they were attacked by Sam 7. They only needed to release infrared bait bombs immediately to easily ensure their safety. This interference bomb can radiate strong infrared rays. As long as it is placed around the protected target, Sam 7 cannot distinguish the difference between the bait bombs and the aircraft itself. In fact, because Sam 7 has a very poor discernment ability, US pilots do not even need to cast the bait bombs they carry in actual combat, but only need to change directions quickly and fly quickly towards the sun. After flying for a few seconds, Sam 7 will fly towards the sun stupidly. Even if there is no sun, the pilot only needs to dive the aircraft and pull it up to avoid such crude air defense weapons. It is just a little dangerous.

After Chen Kangjie brought out these reasons, he said to McClellan, "Are you not as confident as your current planes 20 years ago? Are you not as confident as your skills in the Vietnam War?"

Chen Kangjie is considered to be the army of McClellan.

"Haha, it seems that I can't agree," McClellan said with a wry smile.

"It seems a bit inappropriate to give you extra money. When you finish it, I will use a business plane to pick you up and drop off your family to and from Hawaii, and provide a week of hotel accommodation," Chen Kangjie patted McClellan's shoulder and said gratefully.

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

,,,,,,.

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

"This is Lyme 1. I saw three trucks in the east of the bridge." McClellan flew alone in the fighter plane and made a short parallel flight with Chen Kangjie and the others. As for the lines, it was indeed what McClellan said, but for Chen Kangjie, the lines are not important, as long as there is an image, the lines can be dubbed in the later stage.

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

After the three fighter planes formed the formation, they began to roll sideways in sequence just 60 meters away from Chen Kangjie and the others.

At this time, on a yacht on the sea, Rofoman was holding another camera and doing a back shot. For safety reasons, they were still a bit far from the bridge, but the distance was narrowed by the camera. In front of the convoy, in the rear compartment of a Toyota pickup truck, Jeddica was ready to shoot the scene of the convoy moving forward and the bridge was blown up. In the air, Carpenter was also working on another helicopter. His mission was to capture the details of the target being attacked from the air.

The cars used to be driven on the new bridge, but now they are about to start the damage operation. The old cross-sea bridge is on the north side of the new bridge. In order not to harm the new bridge, the direction of the car is reversed during the next shooting process, that is, the car is driving from Marathon to Keishvit.

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

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

"No problem, we can arrive on time."

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

"There will be no casualties in the car, right?" McClellan was a little worried.

"There is no one in the car, the second car is led forward by the first car, it is an empty car, you can boldly do it."

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

With the intention of being careful and not being wrong, the crew applied to the state government to close the bridge for an hour. If other vehicles choose to pass here at this time, it may be affected by the fish pond.

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

"OK, GO", after Chen Kangjie finished speaking, their shooting helicopter dived with the fighter plane. The bullets fired by the heavy machine gun under the wings stirred a row of fountain-like water in the sea, but they were a little unlucky. When the machine gun bullets were paddled from the sea to the trucks on the bridge, they were empty, leaving only a row of deep bullet holes on the concrete floor of the bridge deck, and the huge shells popped out and fell into the sea.

"shit", without a concentrated target, McClellan was a little annoyed.

"My man, it's okay, do it again." Since I didn't hit, what can Chen Kangjie say? I can only comfort me.

"Thank you, I'll fly back right away, I'll come back in two minutes," McClellan said as he would let the plane play a 90° side flight at a low altitude.

"We are waiting for you 800 meters west."

Helicopters can hover, and Harrier fighters can hover, but the truck convoy on the bridge cannot stop at this time and can only continue to drive forward, otherwise it will waste time, so the location they took the photo again can only move 800 meters westward.

"OK".

There was no accident in the second shooting. The truck in the middle was shattered by a row of heavy machine gun bullets. Various debris and parts splashed everywhere. Finally, an explosion occurred directly on the bridge deck. The blazing fire blocked the entire bridge deck, and the thick smoke caused also rushed to a height of more than ten meters. This shot was not only captured in the air, but the two cameras behind the first truck also faithfully recorded the clear process.

"Long, will you have to close up shooting the process of a truck rushing through everyone and the smoke in the back?" Jedica on the ground asked Chen Kangjie via radio.

"That's the shot behind, and take the two shots directly. The terrorists used Sam, 7 missile attack fighter jets and fighter jets to destroy the bridge. At most, they could waste an extra truck. If they didn't finish the shots in the air today, they would have to waste time applying for a fighter jet again," Chen Kangjie replied.

"Directly launch missiles."

"Yes, launch the missile directly. You prepare the Afghan supporting actor and ask him to be more biased. When you want to launch, remember to inform him in advance that the helicopter can drop jamming bombs."

Fighters can rely on their own functions to request this old single-handed air defense missile, but it is different for helicopters. This simple weapon is a bit easy to deal with helicopters. At least the probability of being shot down is two or three times higher than that of fighter jets. Therefore, interference bombs must be dropped in advance to ensure that they are foolproof. I am on the plane. If I am hit, I will dig my own grave.

"clear".

The convoy on the bridge deck stopped. They could not really launch missiles on the speeding truck. It was too dangerous, and the launch location could only be in front of the truck that was burning with smoke.

At this time, there was only one fighter and one helicopter in the sky. All other aircraft were displaced forward to avoid being affected by the fish pond. The fighter was below the front and the helicopter was above the rear. The two aircraft were 150 meters apart, and the distance between them was more than 1,000 meters from the bridge deck.

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

"Old Ka, how about it?" Chen Kangjie did not answer Jeddica, but asked Cameron next to him first.

"Oh, what else can I do? I've gotten on your pirate ship. Now I've got an arrow on the string and I have to fire it," Cameron said depressedly.

I don’t know how hard I have to say about filming for Chen Kangjie, but the most important thing is that it is very dangerous. Now I am actually facing the real attack of surface-to-air missiles. No matter how brave Cameron is, he will not be guilty. That is fake.
