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 conducted by South Korean forces which approached the scale of the My Lai Massacre with reports of thousands of routine murders on civilians primarily the elderly , women and children . A separate study by a RAND Corporation employee Terry Rambo conducted interviews in 1970 in ARVN/civilian areas on reported Korean atrocities . Widespread reports of deliberate mass-killings were reported to have occurred , alleging that these were systemic , deliberate policies to massacre civilians with murders running into the hundreds . These policies are also reported by US commanders , with one US Marine General stating " whenever the Korean marines received fire " or think ( they got ) fired on from a village ... they 'd divert from their march and go over and completely level the village ... it would be a lesson to ( the Vietnamese ) . " Another Marine commander Gen. Robert E. Cushman Jr. added , " we had a big problem with atrocities attributed to them , which I sent on down to Saigon . " Investigations by Korean civic groups have alleged there were at-least 9000 civilians massacred by ROK forces
