Ballistic Silence of Special Years

The bottom of the sea is a silent world, like a grave.

A certain sea area in the northern part of W Island.

seabed.

The sharp knife 2 squad has been divided into 10 tactical groups at this time, each group has three people, and each group carries an underwater micro-propeller to assist in advancing.

And every team member is wearing a fully enclosed rebreather, which is a new type of equipment and a sharp weapon for special forces underwater operations.

There are generally two types of underwater rebreathers, one is open underwater breathing apparatus, which is the common equipment that carries an oxygen tank on the back, wears a mask on the head, bites the breathing mouth, and adjusts buoyancy through air pressure to dive.

The other is called a closed-circuit rebreather (CCR).

In the underwater special operations in the military field, especially in the penetration operations, the fully enclosed scuba is usually used.

Its advantage is that it has a long sneak time and a large dive depth. The most important thing is that the fully enclosed respirator does not produce air bubbles, which can minimize the probability of being discovered.

The underwater micro-propeller looks like a tube with a propeller device at the tail, and generally uses electric propulsion.

The earliest such gadgets were only equipped by the armies of western developed countries, and they were necessary for frogmen to attack and infiltrate long distances during underwater operations.

Take Yingjiang’s DPV small underwater propeller as an example. It is powered by batteries. When carrying two fully armed divers + 50 kg of additional load, the underwater speed still exceeds 2.6 knots/hour. It is also equipped with RNAV underwater navigation system. RNAV includes a 20-channel GPS receiver, trying to extract the last weak GPS signal for positioning.

Of course, the rabbit is not the rabbit that was so poor in the past. The special forces have also changed their shotguns. This underwater micro-propulsion is a new type of equipment that was just issued to the troops last year. Its performance is not inferior to DPV. The depth is within 30 meters.

The propulsion battery lasts for 6 hours while submerged at maximum speeds of 60 m/min to 90 m/min. .

According to the original infiltration plan, the Dagger 2 team will sneak to the shore along the attack route after getting out of the submarine. This is not just as simple as silent infiltration, but to detect the mines here along the shipping route. The situation of the division provides more detailed data for the minesweepers when the follow-up troops attack.

There are generally three ways to clear mines——

The first is contact clearance.This method is mainly used to clear traditional contact detonation mines.Contact clearing is generally carried out by minesweeping boats, which are equipped with underwater high-definition cameras, contact minesweeping equipment and ropes, etc., and the target mines are triggered by remote control minesweeping equipment to detonate.However, this method has a greater degree of damage to boats and equipment, and is generally rarely used.

The second is induction clearing.Induction clearing is mainly used for the detonation of non-contact mines.When in use, the relevant equipment can simulate the sound waves, magnetic fields, water pressure, etc. generated by the ship's navigation, interfere with the fuze of the target mine and detonate it.The implementation of long-distance non-contact mine clearance outside the dangerous area not only improves the safety of mine countermeasures tasks, but also minimizes the loss of related equipment and casualties.

The third is called manual removal.Manual removal is generally carried out by "frogmen".In actual combat, once the enemy arranges mines in harbors, narrow waterways or some hidden corners, traditional mine sweeping equipment cannot work, and “frogmen” need to carry mine anti-mine equipment to the target waters to detonate the mines.Underwater undercurrents are surging, and the process of dealing with mines has a high risk factor, and a little carelessness may cause irreversible results.Therefore, this method is a great test for the diver's diving skills, psychological quality and operational ability.

Because of the urgent task time, Hou Jun's squad is not responsible for demining this time, but for reconnaissance.

Each team's propeller is equipped with a device called a "mine hunter", which is actually a miniature mine-sweeping sonar with a search range of about 100 meters. It is marked on the electronic map of the Beidou system to provide parameters for the minesweepers of the subsequent offensive forces.

"Here is 01, all teams pay attention, time is running out, speed up the advance, we need to reach the shore within 15 minutes."

"02 Received, speed up."

"03 Received, speed up."

……

A series of replies came through the earphones, and the groups were progressing smoothly, Hou Jun felt a little relieved.

It seems that the mission went well.

suddenly
Suddenly, a gray object appeared in front of him, blocking the entire line of sight in the diving goggles.

"what?!"

Hou Jun quickly sent out a signal to signal all groups to stop advancing.

In the darkness, the diving lights revealed a large piece of seaweed-like thing floating about six meters ahead.

Although it is the bottom of the night, it can still be seen with the help of night vision equipment.

That is a huge net!
Hou Jun swam slowly over, reached out and touched the net, wanting to see what type it was.

Maybe it's the nets that the fishermen set up when they were working here?

It's not uncommon, sometimes the nets get lost and they end up as waste in the ocean, floating in the ocean forever.

With this touch, Hou Jun immediately realized that something was wrong.

This net is made of nylon, and it hangs from the water surface to the bottom, and the thread is very thick, which is not the standard of ordinary fishing nets.

This is not a fishing net!
This is the anti-frogman net!

Generally speaking, there will be this kind of anti-frogman net near the military port, just like laying mines, because in wartime, the hostile frogman unit will infiltrate and destroy the ships in the harbor. Not uncommon.

If an infiltrating frogman accidentally crashes into the net, it is no different from an entangled fish. If it tries to break free, it will inevitably make a violent noise, which is easy to be monitored by the sonar officer on duty on the shore or on the ship.

Hou Jun couldn't help secretly heaving a sigh of relief.

Fortunately, I was cautious enough to not let my guard down so I didn't bump into the net.

"Can this little trick stop me?"

He secretly smiled.

I heard that the blue army has mobilized the marine brigade this time, and has transferred the most powerful certain naval special brigade from the fleet.

It was quite scary at first. After all, underwater combat is his old profession, and he has a specialization in art. The veterans of the special reconnaissance battalion held their breath cautiously at first, not daring to underestimate it.

It doesn't seem that way now.

Isn't it the anti-frogman net?

This is the most primitive and low-end defense method.

Idiot!
Can a network be hard to live with yourself and your comrades in arms?

He gestured backwards, motioning for the players next to him to come over.

When the team members arrived, he pointed to the net in front of him, made a scissors gesture, and ordered his men to tear it down immediately.

The equipment brought on his body came into play at this time, and the team members under Hou Jun quickly took out the multi-functional diving knife and moved towards the nylon net.
