319 high-altitude dropping, low-altitude skydiving

Coming out of the conference room, Li Yu and Zhang Li used the fastest speed to prepare the weapons and equipment and other materials needed for this mission, of course, the most important point, research and judgment intelligence, after that, the two of them did nothing, just hurried to sleep.

Sleeping is a kind of enjoyment for the general public, most of the time, sleeping is actually enjoyment for soldiers, but in some special moments, he is no longer enjoyment, but a task, such as at this moment, Li Yu and Zhang Li must seize the time to sleep, replenish physical strength, and reserve physical energy.

After sleeping until eight o'clock in the evening, the two of them got up, and after that, washed, ate, and prepared.

At about nine o'clock in the evening, a Great Wall off-road vehicle with a civilian license plate drove into the guest house, and Li Yu and Zhang Li got into the car and went directly to the air force airport in the car.

They were going to take an Air Force transport plane to the target airspace, and then parachute there.

This time they're going to do HALO.

HALO, or high-altitude dropping, low-altitude skydiving, is one of the most dangerous in skydiving.

"HALO", or High -Altitude- Low-Opening, means that skydivers jump from a high altitude and skydive at a low altitude.

HALO, this is a military parachuting technique developed by the U.S. Air Force in the 1960s for special forces infiltration missions.

The transporter flies at an altitude of 10,000 meters to avoid anti-aircraft missiles and artillery, and the paratroopers will descend to a low altitude at a very fast speed after jumping off the plane to avoid being identified on the radar as much as possible.

This allows special forces to quickly infiltrate enemy countries to carry out missions.

The idea behind HALO is to allow paratroopers to descend from the air to the ground as quickly as possible, while keeping them in the air for a shorter period of time, so that it will be difficult for the opponent's radar to detect them, and everyone can silently infiltrate into other countries' territory.

Since many HALO operations are performed at night, the danger is further increased.

Many HALO parachutes have a feeling of stillness after a minute of free fall, effectively levitating on a column of air that has been impacted.

Parachutes approach the ground at speeds of up to 250 kilometers per hour, which is very dangerous.

Most HALO parachutes use an automatic parachute opener, and they all wear an altimeter on their wrists.

At an altitude of 10,000 meters, the air temperature is below freezing, and the air is very thin, making it difficult to breathe, so the parachute is firmly fixed in a special insulated suit with a breathing apparatus, but the goggles and altimeter quickly freeze.

The Air Force planes will send Li Yu and Zhang Li to an altitude of 10,000 meters to carry out an airdrop, after which they will open a parachute at an altitude of 8,000 meters, and then use the paraglider wings to glide a distance of 40 kilometers to reach the designated place.

Most of the parachute training of ordinary troops is 800 meters away, and it rarely exceeds 1,000 meters.

However, the Black Dragon Commando of the Tiger Brigade has been built in accordance with the standards of the Navy's tactical research group since its establishment, so the requirements for parachuting are also very high; everyone must not only learn to parachute at low altitudes, but also learn to parachute at high altitudes, not only to be proficient in parachuting during the day, but also to train for parachuting at night.

Therefore, Li Yu and Zhang Li are still very confident in this parachute.

This time the mission was a bit special.

Militants have two ways to enter the borders of our country. One is from Batan, it stands to reason that this possibility should be very small, after all, Batan has a good relationship with us, so they are still very supportive of our anti-terrorism work, once a suspicious person is found, immediately arrested, or even killed directly, so the possibility of militants entering from here is not very large, but according to the intelligence of the intelligence department, this time, the militants are likely to enter from here, first, the road here is the best to take, very easy, second, the relationship between Batan and his hostile countries in the past two days has been tense, The attention of the border guards is basically in the other direction, and the militants may want to take advantage of the loopholes;

But there is another possibility, from another country in the immediate vicinity of Batam.

This is unlikely, because the road is very steep and not easy to walk.

However, anti-terrorism work must not be left to chance, and must be cautious, so after research, the higher-level departments made the following arrangements: The anti-terrorism combat team was deployed in Batan, while Li Yu and Zhang Li secretly infiltrated into other countries by parachuting from high altitudes and hid in high places, just in case.

The advantages of them at the high point are, first, that they can detect the intentions of the militants as soon as possible, to see if anyone will come from this road, and if so, immediately notify the anti-terrorist combat team in Batan, as long as the side gets timely information, it is still too late for them to rush over, after all, they have assault vehicles, and there is a road between the two sides, and it is easier for assault vehicles to advance at high speed; In addition, if there is any accident, Li Yu and Zhang Li can also use sniping to block the militants from the border.

The country where Li Yu and Zhang Li are going is actually quite friendly with us at present, and the relationship is quite normal, but this kind of secret operation must ensure the security of intelligence, and once the other party is notified, the militants may not know it in a few minutes, so this infiltration must be secret.

At some point, an officer of the Air Force came over and woke up Li Yu, who was sleeping: "Comrade, wake up, it's here!" ”

Only then did Li Yu open his eyes.

Arrived?

So fast?

However, when he looked down at his watch, he realized that it was actually late.

Tick - Tick – Tick –

In the cabin, a red light suddenly flashed non-stop.

The officer of the Air Force said to Li Yu: "Comrade, you can prepare to parachute!" ”

Li Yu and Zhang Li stood up.

"Check the umbrella!" Li Yu said.

Zhang Li and he first checked themselves, and then helped each other to check each other's umbrellas.

When everything was ready, Li Yu gave a thumbs up to the officer in the Air Force.

At this time, someone opened the hatch!

Rumble!

The cold and bitter cold wind poured in fiercely!

An Air Force officer from the flight team stood next to the cabin, and he gave a thumbs up to Li Yu and Zhang Li, signaling that the hatch had been opened and everything was normal.

"Wear an oxygen mask!" Li Yu shouted.

Zhang Li and he immediately put on the oxygen mask, and after Zhang Li put it on, he raised his hand to indicate that he had put it on, and the officers of the Air Force came to check one by one, very cautiously.

Then it's time to put on your night vision devices.

When everything was ready, the officer of the Air Force shouted at Li Yu: "Jump!" ”

Li Yu gave Zhang Li a thumbs up, and then suddenly began to accelerate forward, rushed forward a few steps, jumped into the air, and jumped into the air.

"Jump!"

The crew standing next to the hatch waved his hand outwards and signaled Zhang Li to parachute!

Bang bang bang!

Zhang Lizhu ran a few steps, and then jumped into the vast air with a whoosh!
