The sas training training ranges from a wide variety of diving subjects.

First of all, it is light diving, with only diving glasses and flippers. It usually dives for 20 meters. During the assessment, it is 25 meters deep and the round trip is 50 meters in total.

There are also night diving. Generally, you take a assault boat from the coast around 7 pm and walk straight forward for about 500 meters. Put a float in the sea. Use a rope about 50 meters to connect a large lead block. Then use a rope about 500 meters to dive to stretch the rope along the coast from the lead block that pulls the float to the bottom of the sea to dive at 9 pm.

Of course, deep diving subjects are indispensable. This subject generally dives 50-75 meters, with oxygen cylinders and other equipment, and performs various mine removal and explosive device removal operations at the bottom of the water.

In addition to ordinary traditional diving courses, there are also some strange special diving subjects, such as city diving.

What is urban diving? It is to dive in dirty urban rivers or large drainage channels.

Usually the water here is very dirty, and the underwater situation is complicated, with many debris and obstacles. If you are a kid, it is easy to have problems, such as the snorkel being caught or being entangled by debris under the water.

In addition, there are village coast diving. During training, you can directly go to the fishing village by the sea to go into the water for training.

You know, fishermen like to discharge directly, and domestic sewage is not filtered or purified at all, and the discharged things are not just water...

There are animal internal organs, fish internal organs, and food residues. Of course, human excrement is indispensable...

ah!

That feeling!

Before you get into the water, you feel like you are going to hell.

When you go into the water, you feel like you are entering hell.

After getting on the water, looking at the expressions of the people around you, you will feel that you have successfully brought hell to the world!

Every time I go to the water, Zhuangyan will shout in my heart - fly! Shit and urine!

The afternoon class starts at 1:30.

According to the training schedule in recent times, the training of the water projects will generally be conducted from 1:30 to 4:30, and the instructors will be interspersed with on-site teaching and Q&A.

More than half a year has passed since the training camp. From various basic diving training in the school swimming pool to now, the training classes are all considered experienced diving experts.

Everyone moved oxygen cylinders, diving gear and other things to the beach, got on a rubber boat, and then drove along the coastline to a pier about 1 nautical mile away from the school beach.

I came here to conduct docking and blasting training.

This wharf is owned by the military. The water conditions under the wharf are complex. There are many reefs and various cement columns, and even various strange miscellaneous objects such as waveproof piers that have been washed down over the years.

This training simulates enemy agents sneaking into the dock, installing underwater explosive devices under the dock, and requiring them to be lifted.

Two 12l oxygen cylinders can support underwater activity for about 4 hours.

Training requires that a fuze of an explosive device must be removed within 30 minutes.

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

Because the explosive device is not only dismantled, but also according to the entire process (paralysis, I am very hesitant to write it here, should I write it in detail), first of all, you need to identify, detect, then evaluate the situation and consequences, and then formulate a set of plans and at least two sets of dismantling filing.

You must know what the best outcome is and what the worst is.

Once the worst situation occurs, how to prevent it in advance and reduce the damage to the lowest point.

Then the demolition is performed.

So, now we have simplified the previous things and went directly to the demolition to tell the team members what device it is.

This is actually much simpler.

Going into the water is just to adapt to various bomb disposal operations in the water.

Underwater bomb disposal, under the premise that the situation is unknown, the Viper system dive tool is generally used to dive.

The so-called viper system is a closed scuba diving tool, which every underwater defense brigade student must learn to use this diving system proficiently.

The viper diving tool used here is produced by Kangaroo Country. The advantage of this system is that its bubble discharge can be almost negligible.

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

For example, some fuse models of torpedo or mines belong to the non-trigger fuse type and are equipped with fuses similar to sonar. If the submersible tool is open or semi-closed, the bubbles and sounds generated during underwater operation are too close to each other, which can easily detonate these sensitive mines and torpedoes.

Today's scuba diving training program includes links and ventilation with the conventional double cylinder system of Scuba, wearing a Viper combination mask with a mouth-biting oxygen supply system, and using the Scuba system to ventilate, underwater explosion discharge at the dock, light diving of 10 and 25, 35 meters, diving extract, wearing fins and masks and diving shoes underwater, etc.

In the underwater bomb disposal course conducted on the dock, Class 1 was divided into four groups, two people in a group, and then one of the two team members was left to cooperate with one of the two team members to perform underwater homework.

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

The dock discharge project is very simple, but Zhuang Yan unexpectedly did not partner with Cui Weinan and Wei Shuping today.

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

Usually, due to the problem of convenient language and communication, Zhuang Yan partnered with Wei Shuping for most of the time. After all, Lao Wei can listen but not speak, so Zhuang Yan is more convenient to partner with him.

I don't know if it was Instructor Ahmed who drew the tendon today, and suddenly chose to let Zhuang Yan and

The partner is Lieutenant Gallon.

The training went smoothly from the beginning.

However, a little bit of a small situation occurred when diving 35 meters.

The problem lies with Gallon.

Light snorkel is not a project for two-person partners, and it is required to be performed by a single person.

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

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

There are several main training methods for light diving, such as knotting along the rope at the bottom of the water, quickly finding objects at the bottom of the water, or completing simple placement and installation, etc.

That day was underwater search, and everyone had to dive to the bottom of the water in one breath, then find the marker and take it back to the ship.

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 up first.
