number of victims with 420 and 90 respectively, and in five other places a total of about 100 civilians were executed. Two further massacres were reported by soldiers who had taken part in them, one north of Đức Pho in Quảng Ngãi Province in the summer of 1968 (14 victims), another in Bình Định Province on 20 July 1969 (25 victims). Tiger Force, a special operations force, probably murdered hundreds of civilians during a 6-month period in 1967. According to the Information Bureau of the Provisional Revolutionary Government of South Vietnam (PRG), a shadow government formed by North Vietnam in 1969, between April 1968 and the end of 1970 American ground troops killed about 6,500 civilians in the course of twenty-one operations either on their own or alongside their allies. Nick Turse, in his 2013 book, Kill Anything that Moves, argues that a relentless drive toward higher body counts, a widespread use of free-fire zones, rules of engagement where civilians who ran from soldiers or helicopters could be viewed as VC, and a widespread disdain for Vietnamese civilians led to massive civilian casualties and endemic war crimes inflicted by U.S. troops. One example cited by Turse is Operation Speedy Express, an operation by the 9th Infantry Division, which was described by John Paul Vann as, in effect, "many My Lais".

The 2nd Marine Brigade reportedly perpetrated the Binh Tai Massacre on 9 October 1966. In December 1966, the Blue Dragon Brigade reportedly perpetrated the Bình Hòa massacre. The Second Marine Brigade perpetrated the Phong Nhị and Phong Nhất massacre on 12 February 1968. South Korean Marines reportedly perpetrated the Hà My massacre on 25 February 1968. According to a study conducted in 1968 by a Quaker-funded Vietnamese-speaking American couple, Diane and Michael Jones, there were at least 12 mass killings committed by South Korean forces that approached the scale of the My Lai Massacre, with reports of thousands of routine murders of civilians, primarily the elderly, women and children. A separate study was carried out by RAND Corporation employee Terry Rambo, who conducted interviews in 1970 on reported Korean atrocities in ARVN/civilian areas. Widespread reports of deliberate mass killings by Korean forces alleged that they were the result of systemic, deliberate policies to massacre civilians, with murders running into
