1972-5
The ARVN took over the base and at the start of the Battle of An Lộc in April 1972 it was defended by a battalion of the 7th Regiment, 5th Division and was also the base for the 9th Regiment. A combined 105mm and 155mm artillery battery was also based at Quần Lợi. On the evening of 7 April elements of the People's Army of Vietnam (PAVN) 9th Division overran Quần Lợi, the 7th Regiment was ordered to destroy their heavy equipment and fall back to An Lộc. Once captured the PAVN used Quần Lợi as a staging base for units coming in from Cambodia to join the siege of An Lộc and key members of COSVN were based there to oversee the battle. On 8 August the 18th Division launched an assult to retake Quần Lợi but were stopped by the PAVN in the base's reinforced concrete bunkers. A further attack was launched on 9 August with limited gains and attacks on the base continued for the next 2 weeks eventually gaining one third of the base. The ARVN finally atatcked the PAVN occuppied bunkers with TOW missiles and M-202 rockets and this broke the PAVN defense forcing the remaining defenders to flee the base.

The base is largely overgrown but a small area appears to remain in use by the PAVN.
