Because this kind of assessment takes a long time, usually more than an hour, only three groups can be released at a time, and two sea areas are set up for assessment at the same time, and six groups are released at the same time, and assessment is conducted in two sea areas.
Zhang Jian and Fatty Wei are in a group and are conducting assessments in sea area A.
The remaining 4-6 groups will be assessed in sea area B.
After getting on the boat with the equipment, Fatty Wei glanced at the positions of groups 2 and 3 not far away, and whispered to Zhang Jian: "It seems we are lucky!"
Zhang Jian turned around and saw the problem.
The two members of Group 2 are from the Air Assault Battalion, and the Group 3 is composed of soldiers from the Reconnaissance Battalion of another Marine Brigade.
In other words, Group 3 is highly competitive, but Group 2 is definitely not as good at underwater subjects as the people from the reconnaissance camp because of their different professional focus.
Fatty Wei added: "It seems we won't be at the bottom."
Zhang Jian nodded vigorously and stretched out his hand.
Fatty Wei also stretched out his hand, and the two held their hands together and shook them vigorously.
"come on!"
The assault boat that picked up the team members arrived at the starting point with ease.
Fatty Wei looked at the sea water beside the boat and reached out to stir it up.
The water is very cold, drizzle has begun to fall in the sky, and the sky is getting gloomier.
The two of them are familiar with this sea area. The water depth is about 40 meters, and the water depth in the target sea area does not exceed 50 meters.
This area is a bay area, a natural haven, and the waves are not big, otherwise the difficulty of riding on the water will increase.
【In view of the general environment,
"Check the equipment!"
The veteran Jiaolong on the assault boat issued an order to the two of them.
The two quickly checked their diving equipment, underwater propellers, and finally the explosives.
This thing is the key point. Don't underestimate underwater explosions. It's not as simple as diving in there, planting a bomb and then blowing it up.
The key is to find and identify goals.
Once you make a mistake, you won't be able to find the target ship anywhere in the vast sea.
Soon, everything was checked.
The three groups jumped into the water at the same time at the sound of orders.
The first 800 meters of sea riding is an appetizer, comparing speed and propeller control capabilities.
Zhang Jian is responsible for controlling the thrusters, and Fatty Wei is responsible for position correction and distance calculation.
Fatty Wei was right.
From the very beginning, Group 2 lagged behind the other two groups by more than ten meters.
The control of this kind of micro thruster is like driving a motorcycle, but during the process of driving, you have to keep looking at the compass on the thruster and aim it in the correct direction. Once the deviation is corrected, the team will fall behind.
Group 2 was left behind at the beginning probably because they were not very proficient in operating the propellers, which led to the lag at the start.
Zhang Jian is an officer, and he is familiar with this subject. There is almost no difficulty in the first 800 meters. All he needs to do is to maintain the same shape with Fatty Wei, minimize the resistance, and increase the speed.
As expected, Group 3 was also a veteran, after all, they were soldiers from the reconnaissance battalion. At the beginning, they were neck and neck with Zhang Jian, at the same speed.
But after driving 400 meters, Group 3 suddenly slowed down for a few seconds.
Fatty Wei laughed loudly: "They must have discovered that their azimuth angle was off!"
It’s the same principle as land azimuth travel.
Fatty Wei's job is to constantly monitor whether the azimuth angle is wrong. If there is an error, he must correct Zhang Jian and correct it.
Group 3 slowed down, and two team members were obviously talking and arguing.
However, we quickly reached a consensus, corrected a little to the right, and continued to catch up.
The target ships of the three groups were at different locations, more than two hundred meters apart, so everyone took different routes.
The first turning point in the 800-meter ride was when Zhang Jian’s group arrived first.
"Slow down!"
Fatty Wei shouted: "Correct 30 degrees to the right!"
Zhang Jian reacted quickly. After a slight pause of less than three seconds, the propeller type immediately made the correct turn and rushed towards the dive position.
According to the subject settings, drive another 400 meters. If the two people's positioning is correct, they will find the dive point. There will be an assault boat driven by the veteran Jiaolong. They will not issue orders, but will only watch indifferently and record the team's performance.
Did you follow the rules and dive at the designated dive location, without crossing the line or misaligning yourself?
Any defects will be recorded and used as grounds for deduction of points.
Zhang Jian pushed the propulsion gear to the highest speed, and Fatty Wei felt like he was riding on a dolphin, riding the wind and waves on the sea and moving forward.
The sea breeze was fierce, and the raindrops gradually became bigger, hitting his face. Fatty Wei didn't even dare to raise his head while he was shouting - because at this time, he had to stare at the positioning device with naked eyes. If there was any deviation, he needed to correct it at any time. He raised his head
Sea water and rain will rush into your eyes and wet the screen of the positioning device, making the pointers and numerical values on it unclear.
Therefore, Fatty Wei could only tilt his head to prevent his eyes from being splashed with seawater, and also used his body to protect the positioning device.
Finally, Zhang Jian’s group was the first to reach the dive site.
Sure enough, there was an assault boat floating on the sea near there. One of the two veterans of Jiaolong on the boat had a telescope hanging on it. They looked at Zhang Jian and Fatty Wei expressionlessly.
"Is the location right!?"
Zhang Jianwen is called Fatty Wei.
Fatty Wei quickly checked the azimuth and locator, and finally nodded: "Yes, it's here."
"Dive!"
Without saying a word, Zhang Jian put on the eyepiece, put on the respirator mouthpiece, and dived immediately.
Gradually, as the pressure under the water increased and the water temperature dropped, Zhang Jian felt that his body's blood pressure was increasing and his breathing pressure was accelerating.
If they were new recruits, they would feel panic at this time, but Zhang Jian and Fatty Wei are both veterans. They have dived countless times and have no worries in their hearts.
However, low temperature and humidity have greatly increased the difficulty of underwater positioning. Because there is no reference object underwater, it is surrounded by water, and there is no distant view of the water. There are no trees, no mountains, and no bottom. Every Haite team member
They are all people with a strong sense of direction. Those who have no sense of direction are immediately confused when they reach the bottom of the water. They can't distinguish between east, west and north, let alone find the right direction to sneak 800 meters to find a target ship.
Fatty Wei, the guy in charge of positioning, was so familiar with positioning equipment that determining the direction had no difficulty for him.
After reaching a depth of 6 meters, he gestured to Zhang Jian and pointed to the left front, indicating to move forward.
After that, he came over and grabbed Zhang Jian's diving belt. Zhang Jian turned the gear valve again, and the micro-propeller sprayed out water jets and rushed forward.
800 meters underwater is a long time, and the world seems to be isolated from the sea.
All communication between the two is limited to sign language.
It's a wonderful feeling.
It seems that Zhang Jian and Fatty Wei are the only two people left in the world.
In order to get the correct direction and quickly approach the target ship, Fatty Wei indicated that he should move as close to the water as possible and maintain a depth of 5-6 meters underwater.
After all, it was a cloudy day and it was still raining. The visibility in the sunless sea water was too poor. Suddenly a gray thing appeared in front of him. The carrier suddenly hit something. Then, Fatty Wei saw Zhang Jian's whole body rolled up into a ball.
