On 8 May 1970 a group of soldiers from 3 RAR who had served in South Vietnam attacked 1,000 Moratorium marchers who were peacefully protesting against the war in Adelaide. This led to 21 soldiers facing disciplinary charges, including five who had been arrested by police and also faced civil charges. The Army disciplinary heading led to at least 16 of the soldiers being fined or imprisoned for a short period. At least three of the soldiers were convicted when their cases were heard by the Adelaide Magistrate's Court; two did not receive a penalty and the other received a small fine.
