As we all know, the old China did not have a complete military industry system. The weapons of the People's Liberation Army were basically seized on the battlefield. As far as artillery and firearms used in war are concerned, they are produced in 98 arsenals in the world, with as many as 110 types and models, which has caused great difficulties in logistics support.
After the outbreak of the Korean War, under the unified organization of the Central Military Commission, in order to improve the combat effectiveness of the troops, every effort was made to make every effort to increase the equipment of the troops by one step. Even so, the Northeast Frontier Force still can't unify the weapon system, in short, it is all Xiaomi plus rifle.
The history of world war tells us that there is never an unbreakable line of defense. So what tactics did the Chinese People's Liberation Army use to make the U.S. army unbreakable?
Since ancient times, the Chinese nation has been a nation full of wisdom, and the Long March of 25,000 miles is a miracle of the world. During the Korean War, the Chinese People's Volunteer Army created a line of defense that could not be broken, destroyed or destroyed. This line of defense is an underground tunnel constructed by the Volunteers on the 38th and 8th lines, known as the Great Wall Underground.
The Great Wall stretched hundreds of kilometers from the east coast of North Korea to the west coast. The United Nations led by the U.S. Army, despite their indiscriminate bombardment, did everything they could to stay one step beyond the thunder pool, but it is still unknown who actually initiated the tunnel warfare. The first battle in the tunnel was General Li Yuan, the 140 division commander of the volunteer army.
After the five battles in 1951, the United Nations Army led by the United States aggression was hit hard by our volunteers. The enemy and our two sides were deadlocked on the 38th and 8th lines. The enemy tried to occupy a large area of our country through armistice negotiations. Of course, we resolutely refused. They relied on their superior equipment and successively attacked our summer offensive and autumn offensive on the western front of North Korea.
Looking back at the course of our division's crushing of the enemy's summer offensive and autumn offensive, I deeply felt that General Li Yuan, who pioneered the tunnel battle, played an important role.
At the beginning of the summer offensive, Chief Li went deep into the front to observe the rules of the enemy's attack. One day he went to the frontier and accidentally found the prototype of a tunnel war: a cat pierced ear can hold 3-5 people. An idea came to mind. If you dig deeper and larger, and use wooden clogs to support it, you can prevent artillery and air defense and reduce military casualties.
