- The Chu Pao Pass area is cleared and the highway between Kontum and Pleiku opens to commercial traffic in early July. However, the enemy continues to harass traffic with sporadic attacks by fire and Route QL-14, although open, remains insecure.
- A total of six enemy regiments are reported in northern Dinh Tuong Province, about 65 km southwest of Saigon. After taking Kompong Trabek, NVA forces, probably elements of the 9th Division, supported by local Khmer Rouge units, are tightening control over Route QL-l from the Parrot's Beak area to Neak Luong on the Mekong River. By July 2 (22nd day), only two towns in the area remain under National Khmer control, Neak Luong and Svay Rieng. The series of heavy engagements between the NVA and South Vietnamese troops in the Elephant's Foot area in Military Region 4 continue; NVA continues to put pressure on QL-4, the supply route between the Delta's rice bowl and the nation's capital, while launching a series of coordinated attacks on the towns of Sam Giang, Cai Be and Cai Lay in Dinh Tuong Province from mid-May through mid-July; the attacks are driven back by territorial forces with strong support from U.S. tactical air and helicopter gunships.

Up to eight divisions operate along the border in the dry season (December to June) and pull back to established garrisons during the rainy season (July to November).

July 1981 (6th and 7th months, Year of the Rooster [Tan Dau]): The beginning of the rainy season forces the Vietnamese to pull back from the border town of Pailin, which they have occupied since May in response to Khmer Rouge advances at Phnom Malai.

July 1982 (5th and 6th months, Year of the Dog [Nham Tuat]): Some 20,000 PAVN troops are sent home in the first major troop rotation since 1978. Taking their place are fresh troops, many of them southern draftees sent to complete basic training in the forward bases of understrength divisions.

July 1985 (5th and 6th months, Year of the Ox [At Suu]): This year as the rainy season begins ten PAVN combat divisions remain in Cambodia, all of them understrength, some with as few as 5000 troops.
