The main reason is that the main body of the war has changed, and China has changed from the Republic of China to the People's Republic of China.
Regime: The Kuomintang was only nominally unified, and the New China Central Committee deserved it.
1, the warlords of the Kuomintang period were independent and could not exert China's national strength.
2, the new Chinese regime deservedly ruled almost all of China, there were no divided warlords, and the military orders were smooth, ensuring the stability of the country. The Fangxin government was efficient and unified in government decrees, ensuring political stability and enabling New China to use the strength of the whole country to resist the United States and aid Korea.
Scale: The War of Resistance Against Japanese Aggression was an all-out war, and the Korean War was a local war.
1, because it is not a full-scale war, the war only exists on the Korean Peninsula, which greatly alleviates the national defense pressure of the Chinese army and allows China to concentrate elite troops into the Korean rotation war.
2, because it is not an all-out war, the korean war does not involve the fundamental interests of China and the United States. The United States could not win the war without expanding the scale of the war and without attacking China itself, so it had no choice but to cease hostilities.
State: The War of Resistance was fought on the mainland, the Korean War was fought in Korea, China's rear was stable, and industrial forces continued to develop.
1, the volunteer army fought in Korea, the war almost did not affect the country, the rear can provide stable resources to support.
2. While fighting wars, the volunteer army engaged in large-scale economic construction and recovered the northeast, and the military industry recovered rapidly.
3, the volunteer army began to fight, the Soviet Union began to provide economic assistance to China, heavy industry first began to build, it can be said that China is getting stronger and stronger.
Logistics: Strive to ensure logistics and strive to be the best.
1, the volunteer army went to the front line to fight, basically eat better than ordinary people in the rear, you can still eat enough, festivals and so on dumplings and meat.
2, the front line of the volunteer army fought, the rear at all costs to transport arms to the front line, military materials have not been completely cut off.
3, the soldiers and horses did not move grain and grass first, and the supply of materials in the rear of the volunteer army was guaranteed. Before the volunteer army entered the DPRK, the materials were hoarded to the Yalu River, the top level began to ask the Soviet Union for ammunition, and when the Korean War began, they found that the fried noodles were easy to use, so they mobilized the entire northeast people to make fried noodles.
Equipment: Equipped with the best equipment you can use.
1, the weapon is equipped with the best equipment that can be obtained. The troops who entered the DPRK concentrated the best equipment available in the country, and the grass-roots firepower was similar to the virtues of the World War II period.
2, advanced equipment gives priority to ensuring the front line, and there is no idea of preserving strength. Soviet-made weapons were given priority to supplying the army, and the quantity and quality of the army's firepower and heavy weapons in the later period were significantly improved.
3, pay attention to weapon imitation and research and development. The first time to capture the new weapons of the US military capable of research and development will be immediately developed and equipped with troops.
Combat attitude: Most of the elite troops entering the DPRK do not have the idea of preserving strength.
1, the army entering the DPRK is almost all elite troops, such as the 38th Army before the Korean War.
2, the troops obey the command, there is basically no cowardice, unauthorized retreat, avoidance, preservation of strength and other behaviors, combat deployment can generally be carried out as planned.
3, pay attention to the lives of soldiers. Contrary to the impression, the volunteer army cherished the lives of soldiers, and tried their best to avoid unnecessary sacrifices and preserve their living forces during combat. (Of course, this is relative to the Soviet Union and Japan's desperate attack, and the Nationalist army abandoning its teammates at every turn)
Army command: Officers and men are equal, the leading role is obvious, the tactics are flexible and changeable, and they are good at summing up experience
1. Officers and soldiers are equal, the leading role of grass-roots officers is obvious, and the combat effectiveness is obviously guaranteed.
2, flexible strategy and tactics, the army eats a long and wise, does not tacitly abide by the stereotype. Timely adjustment of operational objectives, such as: from the annihilation of the formed US army to the annihilation of the formed ROK army, and the creation of mass aircraft, blowing up stones and burying tanks, tunnel operations, cold guns and cold guns sniper warfare and other tactics.
Combat mobilization: The political mobilization ability is strong and the combat effectiveness is guaranteed.
1, the volunteer army political mobilization ability is super strong, the volunteer army generally feels that when the soldier is killed, it is the country, and it is dead for the country, and it is not afraid of sacrifice.
2, the domestic enthusiasm for defending the family and defending the country is high, especially the victory in the early stage of the war, which greatly stimulates the patriotic enthusiasm of the Chinese people, the young people enthusiastically join the army, and the strength and combat effectiveness are guaranteed.
Campaign planning and deployment of large corps: Commanders and fighters have a high level of combat and have rationally brought into play their combat effectiveness.
1, the campaign planning and corps deployment are generally reasonable, the command is appropriate, the advance and retreat are well-founded, and there is no large-scale collapse.
2, the strategic objectives were adjusted in a timely manner, and there was no excessively blind offensive and excessively blind retreat.
Topography:
1, North Korea's rugged terrain is not conducive to the deployment of large groups of US troops, but it is conducive to the penetration of volunteer infantry to carry out attacks.
2, the rugged terrain seriously weakened the effect of US bombing and shelling, which was conducive to the preservation of the active strength of the volunteer army.
In addition, the United States is full of anti-war, and China basically supports the War to Resist US Aggression and Aid Korea. The people of northern North Korea support it, and south Korea's internal divisions are also one of the reasons.
