During Operation Arc Light from 1965 to 1973, the United States deployed B-52F Stratofortresses from bases in the US to Guam to provide battlefield air interdiction, including strikes at enemy bases, supply routes and behind the lines troop concentrations, as well as occasionally providing close air support directly to ground combat operations in Vietnam. The conventional bombing campaign was supported by ground-control-radar detachments of the 1st Combat Evaluation Group (1CEVG) in Operation Combat Skyspot.

The Battle of Binh Ba, also known as Operation Hammer, was a battle during the Vietnam War. The action occurred when Australian Army troops from the 5th Battalion, Royal Australian Regiment fought a combined force of People's Army of Vietnam (PAVN) and Viet Cong (VC), including a company from the PAVN 33rd Regiment and elements of the VC D440 Battalion, in the village of Bình Ba, 5 kilometres (3.1 mi) north of Nui Dat in Phuoc Tuy Province. The battle was unusual in Australian combat experience in South Vietnam as it involved fierce close-quarter house-to-house fighting, although the majority of enemy killed was through heavy artillery and air-bombardment. In response to PAVN/VC attempts to capture Binh Ba the Australians assaulted the village with infantry, armour and helicopter gunships, routing the VC and largely destroying the village itself. Such battles were not the norm in Phuoc Tuy, however, and the heavy losses suffered by the communists forced them to temporarily leave the province. Although the Australians did encounter PAVN/VC Main Force units in the years to come, the battle marked the end of such large-scale clashes, and ranks as one of the major Australian victories of the war.
