A naval unit that undertakes the task of crossing the sea and landing. Some countries call it naval infantry. It is usually composed of infantry, artillery, armored forces, engineers, reconnaissance and communication units, and some aviation units, which are generally compiled in the order of divisions (brigades), regiments and battalions. It is mainly equipped with infantry automatic weapons, portable self-propelled artillery, surface-to-air missiles, amphibious tanks, amphibious armored transport vehicles, hovercraft, fixed-wing aircraft and helicopters. Its task is: to carry out cross-sea landing operations and anti-landing operations independently or in cooperation with the army. When landing in cooperation with the army, he usually serves as the landing advance team, first rushing ashore to ensure the subsequent echelon landing; It can also cooperate with the army to undertake coastal defense tasks. From15th century to16th century, some countries established specially trained landing combat troops in order to expand overseas. /kloc-In the middle of the 0/7th century, Britain established the Naval Infantry Regiment. Since then, Russia, Portugal, France, Spain, the United States and so on have established the Marine Corps or the Marine Corps. In World War II, the Marine Corps developed rapidly, and the marine corps of various countries played an important role in landing operations. After the Second World War, countries such as the United States and Britain also used the Marine Corps for local wars many times. For example, the United States used the Marine Corps when it invaded Korea and Vietnam, and Britain used the Marine Corps in the Falklands War. During the Revolution of 1911 in China, the Guangdong Revolutionary Army once established the Marine Corps. 19 14 The government of the Republic of China established the Marine Corps. The PLA Navy established the Naval Marine Division on 1953. The Marine Corps of the Chinese People's Liberation Army has made important contributions to the landing operations of coastal islands such as the liberation of Yijiangshan Island. In the early 1990s, there were Marines in the armies of more than 50 countries and regions in the world. The United States Marine Corps is an independent service. Because of its unique position and function, it is regarded as the "fourth service" by Americans. The US Marine Corps is the largest elite force in the world, with a total of about194,000 men and women. Three divisions and three aviation wings are equipped with 4 16 fighters. It is even much larger than the entire army of most countries. The Marine Corps is the force that the navy undertakes the task of crossing the sea and landing, and it is a fast assault force to carry out amphibious operations. It is usually composed of infantry, artillery, armored forces, engineers, reconnaissance, communications and other departments (detachments). The basic task is to carry out landing operations and anti-landing operations independently or in cooperation with the army. Its establishment sequence is brigade, battalion (regiment), company, platoon and squad. The Marine Corps is an infantry specially trained for amphibious assault operations. They can land on the coast of Dong Jun from sea carriers, including enemy cities or places occupied by the enemy. In the strategic resource storage area of the city, crude oil and rubber are needed to produce the Marine Corps. Marine Corps is a special branch of military science. Their training is to prepare for various joint operations of the armed forces. The First Marine Corps officially served in the American War of Independence, but it was not until after this war that they officially became active in the world. The United States Congress rebuilt the Marine Corps in July 1798. The legend of their perseverance, strict discipline and strong adaptability also made them play an important role in the major wars of 19 th century and 20 th century. 1987, General Kelly, commander of the US Marine Corps, was the first to stand up and give a standard American military salute after watching the performance of the Chinese Marine Corps. A reporter came forward and asked, "General, do you really think their performance is excellent?" The general replied, "Yes." The reporter said: "It is said that these performers are all selected from the army and cannot represent the quality and level of the whole army." The general said, "But they are representatives of the whole army. Did you notice their faces after the performance? No satisfaction, only regret. They must feel that they haven't finished. An army that dares to face up to its own shortcomings and never satisfies the status quo will never be in an invincible position. " This is the Marine Corps in China. This is an army that has amazed military strategists from more than 20 countries in the world. This unit is praised by the Chinese as "the dragon on the sea and the tiger on the land". This force can attack quickly from the air to the land, from the sea to the water, and from the south to the north. This is a magical army. Marine Corps is an amphibious combat force composed of various arms and services, which can make quick landings and undertake coastal and island defense or support tasks. The marine corps has a complex combat area and fierce combat. It often needs to cross the sea to fight, attack the enemy behind, go deep alone and fight together. It is a fist to deal with local wars and military conflicts, and also a "sharp knife" in joint offensive operations, which plays an important role in modern wars. Chinese Marine Corps: Since King Charles I of Spain established the first Marine Corps in the history of human war in 1537, the United States, the Soviet Union, Britain, France and other countries have successively owned their own Marine Corps. In the Second World War, the Marine Corps went on and on in Normandy, Guadalcanal, Iwo Jima, Okinawa and other landing operations, with invincible achievements, and was known as the "most offensive army" in the world. After the war, the world's maritime powers vigorously developed the Marine Corps. From the creation of the Marine Corps more than 200 years ago to today, the United States has developed into an assault expeditionary force of about190,000 people and has become an elite division of the American armed forces. China, with a vast sea area of more than 3 million square kilometers and more than 6,000 scattered islands, established the Marine Corps in 1953. At that time, in order to liberate the coastal islands of China, the Marine Corps, the Marine Division and the amphibious tank were set up successively. The formation of the Chinese Marine Corps has contributed to safeguarding the national maritime rights and interests, territorial integrity and unity, consolidating coastal defense and forming necessary deterrence. For decades, the construction of the Chinese Marine Corps has been continuously strengthened. At present, China's marine forces include marine infantry, armored infantry, artillery, armored soldiers, engineers, tank soldiers, signalmen, amphibious scouts, anti-tank soldiers and other arms. Equipped with all kinds of infantry weapons, ferry and landing equipment made in China. They are called "the army in the army". To be an excellent marine, you must go through various forms of strict training. Zhou Naiwen, commander of a certain unit of the Chinese Marine Corps, said, "Use me in the first battle and use me to win" is the slogan that inspires us to act and is also our goal. As a rapid reaction force in charge of amphibious operations, amphibious training and comprehensive training of various arms are the highest forms of marine corps training. Maritime training: Maritime training is usually conducted in remote islands and coastal areas. Food, shelter and training conditions are extremely difficult. The most important feature of high-intensity sea training is high-temperature training. The mission of the Marine Corps is all-round. Soldiers with poor physical fitness can't adapt to the operational requirements. Therefore, the annual anti-high temperature training and adaptation training are the main training subjects of marines, and the standard is to be exposed to the sun for three to four hours. Members of the Marine Corps are directly recruited from local areas and selected from the army and other naval forces. No matter where the soldiers come from, they have to go through this first. Swimming training: The Marine Corps is an amphibious combat force, and besides some subjects on land, it also needs to be equipped at sea. To fight on the island and at sea, we must understand the sea, and swimming training is the most basic subject. In swimming training, recruits should reach 3 kilometers, veterans should reach 5 kilometers, and they should swim 300 meters with 20 kilograms of equipment. In amphibious emergency mobile operations, marines will perform special combat tasks in complex and changeable environments such as air, water, land and underwater, which puts higher demands on the psychological and physical qualities of every officer and soldier, such as endurance, adaptability and sensitivity. In the famous "Tiger Company on Land" of China Navy, everyone is a tough guy, from company commander to soldier, from correspondent to cook. Their daily basic course training includes 100 push-ups, 100 sit-ups, 190 swing arms, 100 strides, 100 squats and stands, and five kilometers cross-country. After completing the physical fitness and basic subject training in the first year, the marine corps recruits began to carry out special professional training in the second year, that is, according to the requirements of special operations, they emphasized the training of special equipment, special technology and special tactics under special conditions. In the Marine Corps, the most intensive training is amphibious scouts. They are responsible for sneaking into enemy islands for reconnaissance, assault and other important tasks, and are called the "team in the team" of the Marine Corps. For scouts, eating, living, walking, fighting and hiding are basic abilities, and field survival training is essential. Three to two and a half ounces of salt per person per day is an extremely harsh and even cruel condition for young people who want to carry out ultra-intensive training.
