Verne Assault reconnaissance operations around the world

Content Preview: Name: Dang Zhenguo.

Born on May 12, 1974.

He is a native of Kashgar Prefecture, Xinjiang Uygur Autonomous Region.

He joined the army in 1992 and served in the 38th Group Army.

In 1994, he entered the China Special Forces Command College for further study.

In 1997, he served in the Chinese Special Service Brigade with the rank of lieutenant and served as a detachment leader.

In 1999 the representative was trained at the "Hunter" school. In the same year, the rank was promoted to captain.

In 2001, he represented China in the "Verne" scout competition and won the first place. He also broke the record since the event was held, becoming the first soldier not to be captured during the competition. In the same year, he returned to China and studied at the National Defense University, China's highest military academy.

After graduating in 2003, he was awarded the rank of major by the Ministry of National Defense, and served as the deputy captain of the special brigade of the Chengdu Military Region of China, and concurrently served as the leader of the "Thunderbolt Group", responsible for the implementation of special tasks, the protection of important military and political personnel, and counter-terrorism.

In 2005, he participated in the operation codenamed "Justice". He killed 17 members of the "East Turkistan" organization in Xinjiang and arrested 4 important leaders, and was praised by the Central Military Commission and awarded special merits. The rank was promoted to lieutenant colonel.

In order to combat armed drug trafficking abroad. The secret organization "Third Commando" specializes in fighting drug traffickers in the Golden Triangle. In the same year, he carried out a cross-border operation and raided the secret base of the largest drug lord in the Golden Triangle.

Killed Aung Su's younger brother Aung Tai and 208 important members, and bombed ......

Submarines run on a power system. There are two types of this:

Diesel-electric power. In the early days, it was tried to be used as a submarine power** such as compressed air, manpower, steam, fuel oil, and electricity. And the first kind of submarine power that is truly mature is to use diesel engine and electric motor (diesel-electric) as the common power**.

Before World War I, submarines began to use diesel engines with electric motors as the power of submarines**. This power was the first type of mechanical power for submarines. The diesel engine is responsible for the power of the submarine to navigate on the surface and to recharge the battery**, and below the surface, the submarine uses the electricity that is pre-stored in the battery.

Since the power that can be stored in the battery must be used by the entire ship's equipment, even at a very low speed, it cannot sail under the surface for a long time, and must be recharged on the surface. The subsequent appearance of snorkels increased the submarine's submersible capability.

The snorkel was developed by the Dutch before World War II and later further improved by the Germans and first used on their submarines. The basic structure of the snorkel is simple, it is an elongated snorkel that directs the outside air to the diesel engine, and the exhaust gases generated are also discharged through the snorkel, and there is a line to prevent and remove the incoming seawater. The use of a snorkel allows the submarine to use a diesel engine in periscope depth conditions, so that the submarine does not have to float to replenish electricity.

The use of snorkels dramatically changed the way submarines operated and were resilient at the time. Before using a snorkel, the submarine must surface for ventilation and recharging, and this operation time is limited to night. After the use of snorkels, submarines only need to extend the snorkel out of the sea to recharge, which not only reduces the probability of being discovered, but also expands the time when submarines can be charged.

In response to this threat, the Allies used special radars carried by patrol aircraft to find tiny snorkels, and if they could not sink the submarine, at least force it to be unable to recharge and not be able to continue tracking and attacking.

Nuclear powerNuclear power is another power developed after diesel-electric power. The principle of nuclear power is to drive a steam turbine to drive a propeller or generator to generate power through the high temperature generated by the nuclear reactor to produce steam in the steam engine. The first to successfully install a nuclear reactor on a submarine was the USS Nautilus submarine of the US Navy, and there are five countries in the world that openly claim to have nuclear power, of which the United States and Russia have the highest proportion of use.

The United States even announced in 1958 that it would no longer build non-nuclear-powered submarines.

Compared with traditional diesel-electric submarines, nuclear-powered submarines have the advantages of large power output, high power endurance (because the fuel replenishment and replacement of nuclear-powered submarines is usually more than 10 years, compared with diesel-electric submarines of only a few weeks or months, it is greatly increased, so it is usually regarded as unlimited endurance), fast speed and so on. However, nuclear-powered submarines have the disadvantages of high technical difficulty, poor stability, high construction costs, high noise and high maintenance requirements. The advent of nuclear batteries solves these problems and means that submarines with superior performance can be manufactured in batches.

You're in ten, right, and so am I, the same as homework, you don't have to write celebrity turns.
