There is a wide variety of diving subjects in SAS Intensive Training.

The first is light diving, with only diving goggles and fins, generally diving 20 meters, diving 25 meters deep during the assessment, round trip, a total of 50 meters.

There are also night dives, generally about 7 p.m. from the coast to take the assault boat straight forward about 500 meters, in the sea to float, the float with a rope of about 50 meters to connect a large lead block, and then dive with a rope of about 500 meters from the traction of the float of the lead block to stretch the rope along the bottom of the sea, for the night dive at 9 o'clock in the evening.

Of course, the deep diving course is indispensable. This subject generally dives 50-75 meters, with oxygen cylinders and other equipment, and carries out various demining and explosive device dismantling operations underwater.

In addition to the usual traditional diving courses, there are also some quirky special diving subjects, such as urban diving.

What is City Diving? It is to dive in dirty urban rivers or large drainage canals.

Usually the water here will be very dirty, and the underwater situation is complicated, there are many debris, many obstacles, if you go down with your hands, it is easy to have problems, such as the snorkel is hanged, or the bottom of the water is entangled in debris.

In addition, there is also village shore diving, which is directly pulled to the fishing village by the sea to train during training.

You know, fishermen like to discharge it directly, and domestic sewage is not filtered and purified without any filtration, and what is discharged is not just water......

There are animal offal, fish offal, food scraps, and, of course, human excrement......

Yes!

That feeling!

Before you get into the water, you feel like you're in hell.

When you go to the water, you feel like you're going to hell.

When you are in the water, look at the expressions of the people around you, and you will feel that you have successfully brought hell to earth!

Every time I go to the water, I will call out in my heart - fly! pee-kun!

The afternoon class starts at 1:30.

According to the recent training schedule, it is generally from 1:30 to 4:30 before the training of water events, and the instructor is interspersed with on-site teaching and Q&A.

More than half a year has passed since the intensive training, and from the various diving basic training in the school swimming pool to the present, the ones left in the training class can be regarded as proficient in diving.

They moved their oxygen tanks and diving gear to the beach, got into rubber boats, and drove along the coastline to a pier about 1 nautical mile away from the school beach.

I came here to conduct training on pier EOD operations.

This pier is owned by the military, and the underwater situation under the pier is complicated, with a lot of reefs and various cement pillars, and even strange debris such as various wave piers that have been washed down over the years.

This training simulated an enemy agent infiltrating a dock, planting an underwater explosive device under the dock, and demanding disarming.

Two 12-liter oxygen cylinders can support about 4 hours of underwater activity.

The training stipulates that the fuse of an explosive device must be defused within 30 minutes.

In fact, this kind of training is relatively simple, and the later courses will be more complicated.

Because explosive devices are not only dismantled, according to the whole process (paralysis, I hesitate to write here, should I write in detail), to see that the first thing is to identify, detect, and then assess the situation and consequences, and then formulate a set of plans and at least two sets of dismantling records.

It is essential to know what the best outcome is and what the worst is intended.

Once the worst happens, how to prevent it in advance to minimize the damage.

Only then is the demolition carried out.

So, now it's time to simplify the previous things, go straight to the demolition, and tell the team what the device is.

It's actually a lot simpler.

Launching into the water is nothing more than adaptation to the water if various bomb disposal operations are carried out.

Underwater bomb disposal, under the premise that the situation is unknown, is generally used to use VIPER system submersibles for diving.

The so-called VIPER system is a closed scuba diving gear, which every cadet of the underwater defense brigade must learn to use proficiently.

The VIPER gear used here is made in Kangaroo Country, and the advantage of this system is that it has a negligible blister output.

The reason why it is necessary to use this kind of closed scuba for diving operations is based on the special design of many underwater explosive devices.

For example, some types of fuzes for torpedoes or mines belong to the type of non-triggering fuze, and are equipped with sonar-like fuzes, if the diving gear is open or semi-enclosed, the bubbles and sounds generated during underwater operations are too close to each other, and these sensitive mines and torpedoes can be easily detonated.

Today's scuba diving training program includes the link and ventilation with the SCUBA conventional two-cylinder system, the mouth occlusion oxygen supply system with the VIPER combination mask off and the SCUBA system for ventilation, underwater explosive disposal at the pier, light dives of 10 and 25 and 35 meters, diving and retrieval objects, underwater removal of fins and masks and diving shoes, etc......

In the underwater bomb disposal course conducted on the pier, the 1st squad was divided into four teams of two people, and then one of the remaining team members and one of the 2nd squad members were paired up to carry out underwater operations.

There are nine groups of 19 people, and three groups are launched at the same time each time, and three instructors carry diving gear to supervise the operation and serve as safety officers.

The wharf EOD project is very simple, but Zhuang Yan unexpectedly did not partner with one of Cui Weinan and Wei Shuping today.

As a class of 9 people, each training session is a group of 2 people, so each class has one person to partner with someone from another class.

Usually, due to the problems of language and communication convenience, Zhuang Yan partners with Wei Shuping most of the time, after all, Lao Wei can listen or not speak, and it is more convenient for Yan Yan to partner with him.

Today I don't know if it was Instructor Ahmed who pulled that tendon, and suddenly chose to let Zhuang Yan and

The partner was Lieutenant Garon.

The training went well from the start.

However, there was a slight situation when diving 35 meters.

The problem is with Garon.

Light diving is not a tandem event and requires a solo event.

Drive the rubber boat to the sea surface opposite the pier, choose a sea area with a depth of about 35 meters, and then two instructors sit on the rubber boat with a stopwatch, and two of the instructors carry oxygen cylinders to the bottom of the water to be responsible for single safety officers.

Everyone put on flippers, put on diving goggles, and jumped into the water.

There are several main types of training for light diving, such as knotting a rope underwater, finding objects quickly underwater, or completing simple placement and installation.

It was an underwater search day, and everyone had to dive to the bottom in one go, then find the marker and bring it back to the boat.

As many people go into the water, there are as many markers as there are, one for each person, and whoever finds it first will float first.

Garon had a slight twist in his search for the marker - he failed to find his target in the first place, and then became the last person to leave the water.
