Jiang Tianhang's individual demonstration ended quickly, because in the actual parachute jump, the time from leaving the plane to reaching the ground was very short.

Of course, the short time mentioned here is when the parachute environment is good and the airborne troops are safe.

The parachute landing in the course of actual combat is likely to involve the battle between the airborne troops and the air defense forces, and the unlucky ones may be beaten to pieces by large-caliber air defense machine guns in the air.

Now the rookies won't participate in actual combat at all, so Zhang Yan didn't consider the tactical actions of those actual combat training.

After Jiang Tianhang landed safely, the Air Force brought in five more veterans, and according to the Air Force staff officer, the next thing to demonstrate was the basic actions of the parachute group.

At the time of parachuting, the officers and men of the whole squad were united from the individual parachute to the whole squad, and there were different air movements.

The advantage of group operations is that they can break through the enemy's air defense blockade more quickly and strengthen their own combat effectiveness, but the disadvantage is that the targets in the air will be significantly larger and can be easily discovered.

At present, the long-range penetration operations of the airborne troops can generally be equipped with light wheeled assault vehicles and paratrooper assault vehicles (such as the Type 03 paratrooper assault vehicle, known as Hot Wheels, and the warrior military vehicle can also provide airborne support. Such a coordinated operation of the machine and step will greatly increase the survivability of the paratroopers in the rear of the enemy.

After Jiang Tianhang and the six of them floated in the air in weightlessness, the six of them changed from a two-person group to a six-person group.

In the wind tunnel, six people hold hands in a circle, a posture that is often seen when parachuting.

All six of them face down, and the camera mounted on the helmet clearly records their every movement, and this training shooting is also for repeated viewing after the training session to check for gaps.

When Jiang Tianhang and the six of them finished demonstrating, the sound of "woo" stopped in the training building.

The staff officer of the Air Force patted Zhang Ye on the shoulder and asked, "How do you look?" Do you want us to demonstrate again? ”

"No, the movement is very standard, I think it should be fine."

"So do you want those trainees to train now?"

As soon as Zhang Ye wanted to answer the words of the Air Force staff officer, Zhang Yan quietly pulled his sleeve, and Zhang Ye immediately turned his head to look at Zhang Yan beside him.

"Can I fly in first?" Zhang Yan asked with a smile.

"This?" Zhang Ye wasn't sure what Zhang Yan was thinking, so he turned to the Air Force staff officer with a questioning look, "This is our third platoon leader, Zhang Yan, what do you see?" ”

"Of course no problem!" The Air Force staff officer said happily.

"Thank you!"

Zhang Yan nodded to the staff officer of the Air Force, and walked straight towards the entrance of the wind tunnel, standing in front of the entrance, he suddenly turned around and shouted to Wang Haoran: "Haoran, immediately lead the team for warm-up training." ”

"Yes!"

Wan Haoran roared, ran to the side with the rookies, and started warm-up training.

Zhang Yan stood at the entrance of the wind tunnel, took a deep breath, and walked in.

After entering the wind tunnel, Zhang Yan's feet were soft and similar to a bouncer, and the huge turbofan engine was at his feet, and the whole wind tunnel looked very large, about four meters in diameter.

The top of the wind tunnel reached the height of a six-story building, and it was only then that Zhang Yan completely figured out what this training building in the wilderness was.

"Zhang Yan, are you ready?"

"Ready!"

"Device start-up, stay safe!"

"Device start-up, stay safe!"

The shouts of Air Force operators echoed on the training ground, and Zhang Yan took another deep breath and waited for the training to begin.

The sound of "woo" came to mind again, and Zhang Yan could clearly feel a gradually increasing thrust under his feet, pushing his body into the air.

"Damn, this one is interesting, it's similar to the inside of the swimming pool."

This is Zhang Yan's first feeling, his body gradually rises into the air with a huge thrust, and the floating state in a weightless state is the same feeling as practicing diving in a specially built swimming pool before. (Astronauts have that kind of swimming pool, with a depth of several tens of meters, simulating the state of weightlessness in space)

As the thrust under him became bigger and bigger, Zhang Yan's body began to rise to a height of about four meters, Zhang Yan began to change his posture, and the whole person fell forward, becoming a parachute posture with his face down and his body hanging in the air.

The huge thrust was blowing on his body, and the camouflage uniform was blown to hunt, Zhang Yan buckled up his windshield goggles and made a safe gesture to the air force that was controlling the equipment outside, and at the same time signaled that he could continue to increase the thrust.

With the continuous increase of thrust, Zhang Yan began to try to change posture and action in a state of simulating various unexpected situations.

"It feels so good to fly, I haven't flown in a long time!"

Zhang Yan floated alone in the air, condescendingly looking at the crowd standing outside the wind tunnel, their eyes were full of worry and nervousness!

When Zhang Yan first came into contact with airborne training, the wind tunnel equipment had not yet been installed in the troops, not even the special forces.

Zhang Yan and the others were taught by the veterans, each holding a square stool, in an open space, to carry out parachute ground training.

There are many steps in parachuting, ground training is the first step, and then there will be folding umbrella bags, basic subject movement exercises, ground cabin training and so on. (The so-called ground out-of-cabin training is to jump to the ground on an airplane, and the plane is parked on the ground.) After going to heaven, there are many things involved in air pressure difference problems, vortex problems, etc., so I won't talk about them here. ）

At the beginning, the training was to lie on the stool with the upper body hanging in the air to simulate the flight posture, which felt like a turtle swinging its limbs desperately, trying to break free from its fate.

Zhang Yan's suspended height is constantly rising, and it has reached a height of about ten meters.

The people standing in the open space couldn't help but sweat for Zhang Yan, who had not been parachuted for four years, and today was the first time he had been exposed to wind flying.

Zhang Yan felt that his breathing could no longer keep up, so he immediately gestured to the operators below to stop training.

The huge thrust under his body slowly decreased, and Zhang Yan could feel that his body was constantly declining, and he himself was gradually changing his body posture with the decreasing height.

When he was about three meters away from the ground, Zhang Yan stood hard, and the whole person stood suspended in the air, and then he soon bent over and bent his knees, becoming a safe parachute posture with his knees and chest.

"He's not in the right position!" The Air Force staff officer looked at Zhang Yan's landing posture and muttered thoughtlessly.

As soon as Zhang Ye, who was standing next to him, turned his head over, Zhang Yan had already fallen on the trampoline.

"Oops,!"

Zhang Yan shouted sharply, causing all the onlookers to run up to the wind tunnel, they were too nervous!
