The bottom of the sea is a silent world, like a tomb.
A certain sea area in the northern part of W Island.
seabed.
The Sharp Knife 2 team has now been divided into 10 tactical groups, each group has three people, and each group carries an underwater micro-propeller to assist in advancement.
Each team member wears a fully enclosed rebreather, which is a new type of equipment and a weapon for special forces in underwater operations.
There are generally two types of underwater breathing apparatus. One is an open underwater breathing apparatus, which is a common type of equipment that carries an oxygen tank on its back, wears a mask on its head, bites its breathing mouthpiece, and adjusts buoyancy through air pressure for diving.
The other type is called closed-circuit rebreathers-ccr.
In underwater special operations in the military field, especially in infiltration operations, fully enclosed scuba is usually used.
Its advantages are long stealth time, large diving depth, and most importantly, the fully enclosed respirator does not produce bubbles, which can minimize the probability of being discovered.
The underwater micro-propeller is shaped like a tube with a propeller device at the tail, and generally uses electric propulsion.
This kind of gadget was first equipped by the armies of Western developed countries. It is a must-have for frogmen to penetrate long distances during underwater operations.
Take Yingjiangjia's DPV small underwater propeller as an example. It is powered by batteries. When carrying an additional load of 50 kilograms for two fully armed divers, the underwater speed still exceeds 2.6 knots/hour. In addition, this equipment also
Equipped with an RNAV underwater navigation system, RNAV includes a 20-channel GPS receiver to squeeze out the last weak GPS signal for positioning.
Of course, the rabbit is no longer the poor rabbit of the past. The special forces have also replaced their guns with guns. This underwater micro-propeller is a new type of equipment that was just issued to the troops last year. It is not inferior to the DPV in terms of performance. It weighs 30 kilograms and is easy to operate.
The depth is within 200 meters.
The battery can last for 6 hours when the propeller is sneaking at the maximum speed of 60 m/min to 90 m/min.
According to the original infiltration plan, after the Sharp Knife 2 team got out of the submarine, they had to sneak along the attack route to the shore. This was not just a simple silent infiltration, but also to detect mines along the shipping route.
The division situation provides more detailed data for the minesweepers when subsequent troops attack.
There are generally three methods for clearing mines -
The first is contact clearance. This method is mainly used to clear traditional contact detonation mines. Contact clearance is generally carried out by minesweepers. During the operation, they are equipped with underwater high-definition cameras, contact minesweepers and ropes, etc., and are triggered by remote control minesweepers.
Target mines are detonated. However, this method causes great damage to ships and equipment, and is generally rarely used.
The second type is induction clearing. Inductive clearing is mainly used for the detonation of non-contact mines. When used, the relevant equipment can simulate the sound waves, magnetic fields, water pressure, etc. generated when the ship is sailing, interfere with the fuse of the target mine, and detonate it.
Implementing long-distance non-contact minesweeping outside dangerous areas not only improves the safety of mine countermeasures tasks, but also minimizes the loss of related equipment and casualties.
The third type is called manual clearing. Manual clearing is usually carried out by "frogmen". In actual combat, once the enemy places mines in a harbor, a narrow channel or a hidden corner, traditional minesweepers cannot operate, and "frogmen" are needed.
Carry anti-mine equipment to the target waters to detonate mines. Underwater currents surge, and the process of handling mines is extremely dangerous. A little carelessness may cause irreparable consequences. Therefore, this method has a great impact on the diver's diving skills and psychology.
Quality and working ability are both great tests.
Because the mission time was tight, Hou Jun's team was not responsible for demining this time, but was responsible for reconnaissance.
Each team's thruster 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 can accurately scan for various mines nearby and then locate them.
Marked on the electronic map of the Beidou system, it provides parameters for the minesweeper of the subsequent offensive force.
"This is 01. Attention, all groups, time is running out. Speed ​​up the advance. We need to reach the shore in another fifteen minutes."
"02 received, speed up."
"03 Received, speed up."
…
A series of replies came through the earphones. Each group was progressing smoothly, and Hou Jun felt a little relieved.
It seems that this 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, instructing all groups to stop advancing.
In the darkness, the diving light illuminated a large piece of seaweed-like thing floating about six meters ahead.
Although it is dark on the seabed, you can still see it with the help of night vision equipment.
That's a huge web!
Hou Jun slowly swam over and reached out to touch the net, trying to see what type it was.
Maybe it's the fishing nets placed by fishermen when they work here?
This is not uncommon. Sometimes fishing nets are lost and become waste in the ocean, floating in the sea forever.
With this touch, Hou Jun immediately realized something was wrong.
This net is made of nylon and hangs from the water surface to the bottom. The thread is very thick and is not the standard of ordinary fishing nets.
This is not a fishing net!
This is a frog-proof net!
Generally speaking, there will be this kind of anti-frogman net near military ports, just like laying mines, because during wartime, hostile frogman detachments will infiltrate and destroy ships in the harbor. This kind of thing is very rare in the history of war.
Not uncommon.
】
If an infiltrated frogman accidentally crashes into the net, it will be no different from a fish that is entangled. If it tries to break free, it will inevitably make a violent sound, which can easily be detected by the sonar personnel on duty on the shore or on the boat.
Hou Jun couldn't help but secretly breathed a sigh of relief.
Fortunately, I was cautious enough and never let my guard down so I didn't hit the net.
"Can this little trick stymie me?"
He chuckled to himself.
I heard that the Blue Army mobilized the Marine Corps Brigade this time, and also mobilized the most powerful Marine Special Forces Group from the fleet.
It was quite scary when I heard it at first. After all, underwater warfare is my main business and I specialize in it. At first, the veterans of the special reconnaissance battalion were cautious and held their breath, not daring to take it lightly.
It seems like that now.
Isn't it just an anti-frog net?
This is the most primitive and low-end defense method.
What a joke!
How can a net catch yourself and your comrades?
He gestured backward to signal the team members next to him to come over.
When the team members arrived, he pointed to the net in front of him, made a scissor gesture, and ordered his men to tear it down immediately.
The equipment they carried came into play at this time. Hou Jun's team members quickly took out their multi-functional diving knives and swam towards the nylon net.
