Nguyễn Chơn

In February 1967, under the regimental commander Hà Văn Trí and his deputy Nguyễn Chơn, the 1st Regiment of the PAVN 2nd Infantry Division launched a fierce attack on a South Korean base garrisoned by a Republic of Korea Marine Corps (ROKMC) company and two United States Marine Corps (USMC) soldiers on the Quang Thạnh hill. The PAVN had captured half of the base but were repelled at last when another ROKMC company arrived as reinforcements by helicopters.^[1][2]

From mid July to mid November of 1974, Nguyễn Chơn led his 2nd Division concurrently fighting against the Army of the Republic of Vietnam (ARVN) 3rd Infantry Division and I Corps's Rangers in the Battle of Đức Dục and the Battle of Thượng Đức, causing irreplaceable losses for the ARVN forces.^{[3]: 114–121 [4]}

In late March 1984, the Military Region 5 forces including the 307th Division, the 1st Regiment of the 2nd Division, the 143rd Regiment of the 315th Division under the command of Maj. Gen. Nguyễn Chơn (newly assigned commander of the Region) launched a major offensive against Khmer Rouge Base 547 in Preah Vihear province. After eight days of fighting, the PAVN forces totally destroyed Base 547, eliminating 1,800 enemy troops, capturing 300 prisoners and 515 weapons. But the 1st Regiment suffered heavy casualties in the 7th day, and the 2nd Division even lost its commander - Col. Trương Hồng Anh in the last day of the campaign, when the PAVN forces already overran the Base.^[5][6][7]
