"Shangganling" commented that our army must persist in the tunnel struggle for a certain period of time when the personnel and material conditions in the tunnel permit and the communication with superiors is smooth. It must seize the opportunity to replenish personnel and materials to the tunnel in a timely manner. It must also have deep troops.

Strong tactical, firepower, material and spiritual support.

At the same time, the tunnel troops must also actively organize classes.

Small-scale sneak attacks, raids, harassment and other combat activities are carried out as a team to counterattack or contain enemies occupying surface positions.

Depth troops must organize snipers or artillery to suppress the destruction of hostile tunnel entrances and effectively protect the tunnels.

The basic method to restore the position is to organize a strong counterattack. The specific method can be to cooperate with the troops inside and outside the tunnel, and to cooperate inside and outside.

You can also move your troops into the tunnel in advance and then rely on the tunnel to launch a counterattack.

And we must be fully mentally prepared and materially prepared for repeated battles.

This battle also reflected the important role of logistics in modern warfare. The volunteers' consumption of materials during the battle, especially the consumption of artillery shells, was unprecedented.

Based on the material reserves for the autumn counterattack, the Volunteer Army's logistics organization implemented key support and did its best to meet all the needs of Shangganling. It also used the automobile company reserved as a mobile force by the logistics department to strengthen transportation support.

There were many signs indicating that the enemy might launch a large-scale offensive in the Shangganling area.

What is even more obvious is that 10 days before the battle, Li Jiqiu, the staff officer of the 2nd Battalion of the 32nd Regiment of the 2nd Division, surrendered to our army and revealed his entire plan to cooperate with the US military in launching an attack on the 597.9 Highlands and the 537.7 Highlands Beishan.

Therefore, many sources, including some authoritative historical materials, believe that from the second day of the battle, the volunteers had determined the main direction of the US military's attack.

In fact, from the Volunteer Army Headquarters and the Third Corps to the 15th Army, there are no changes in troop deployment.

The operational intentions and main direction of attack against the US military were gradually clarified after three or four days of fighting.

This resulted in a great deal of passivity for the volunteers in combat.
