Du Yuming
The 5th Corps was the most elite unit in the NRA, and it is also the only Chinese unit that had tanks and armored vehicles. Its soldiers were combat-hardened veterans from previous engagements against Japanese forces, and as a result, morale was high. General Du Yuming, commander of the 5th Corps, dispatched two divisions to attack the Japanese-held Kunlun Pass. The New 22nd Divisions attack ended up cutting off Japanese reinforcements from the rear and also resulted in the death of the Japanese commander, Major General Masao Nakamura.
