Disputed:20,000 killed in action.

Vietnam claims:

26,000 killed; 40,000 wounded.

China claims: 6,954 killed; 15,000 wounded.

We have a variety of unfavorable factors, directly leading to excessive casualties:

During the war, the Chinese army did not have a recognizable rank and file system, leading to serious disorders in the chain of command; after the war, the Chinese army fully restored the pre-Cultural Revolution rank and file system, and the rank of colonel was added to become a four-tier system.

2. The Vietnamese army made good use of the mines that had caused a large number of casualties in the U.S. Army, which once again resulted in heavy casualties on the Chinese side.

3. The intensity of resistance on the Vietnamese side exceeded expectations, while the Chinese side's lack of experience in coordinated operations between combat vehicles, infantry and artillery led to heavy casualties during the war.

4. The front line communications were poor, and the artillery was unable to give full support due to frequent incidents of mistakenly hitting friendly forces.

5. The Type 59 and Type 62 vehicles were not suitable for use in mountainous jungle areas, and were often attacked by Vietnamese soldiers with anti-armor weapons, resulting in heavy losses. the Type 62 vehicles were too thinly armored and had insufficient defensive capabilities.

6. Infantry lacked armored personnel carriers or infantry combat vehicles to transport them, and relied on walking to fight, with poor mechanical power.

7. Insufficient medical equipment and medical personnel, resulting in a disproportionately high percentage of soldier deaths.

8. Insufficient engineering equipment and technology, especially the lack of modern river crossing tools, affecting the speed of attack.

9. Insufficient air support and lack of night fighting capability.
