Document 5: Military Reaction Force: The Military Reaction Force, Military Reconnaissance Force or Mobile Reconnaissance Force (MRF) was a covert intelligence-gathering and counter-insurgency unit of the British Army active in Northern Ireland during the Troubles, a former member described it as a "legalised death squad". The unit was formed during the summer of 1971 and operated until late 1972 or early 1973. MRF teams operated in plain-clothes and civilian vehicles, equipped with pistols and submachine guns. They were tasked with tracking down and arresting, or killing, members of the Irish Republican Army (IRA). The MRF also ran double agents within the paramilitary groups and ran a number of front companies to gather intelligence. In October 1972, the Provisional IRA uncovered and attacked two of the MRF's front companies—a mobile laundry service and a massage parlour—which contributed to the unit's dissolution.
Document 6: Dirty War: The "Dirty War" (Spanish: "Guerra Sucia" ), was the name used by the Argentine Military Government for a period of state terrorism in Argentina from roughly 1974 to 1983 (some sources date the beginning to 1969), during which military and security forces and right-wing death squads in the form of the Argentine Anticommunist Alliance (Triple A) hunted down and killed left-wing guerrillas, political dissidents, and anyone believed to be associated with socialism. About 30,000 people disappeared, many of which were impossible to be formally reported due to the nature of the issue: state terrorism. The targets were left-wing activists, guerrillas and militants, trade unionists, students, journalists and Marxists and Peronist guerrillas and their support network in the Montoneros believed to be 150,000-250,000-strong and 60,000-strong in the ERP, as well as alleged sympathizers. Some 10,000 of the "disappeared" were guerrillas of the Montoneros (MPM) and the Marxist People's Revolutionary Army (ERP) although the lowest estimate is that the Montoneros and ERP had a combined strength of 5,000. The "disappeared" included those thought to be a political or ideological threat to the military junta, even vaguely, and they were killed in an attempt by the junta to silence the opposition and break the determination of the guerrillas. The worst repression reportedly occurred after the guerillas were largely defeated in 1977, when the church, labor unions, artists, intellectuals and university students and professors were targeted. Although the Montoneros reported having carried out some 600 armed attacks in 1977, the guerrilla threat had greatly declined. The junta justified this mass terror by exaggerating the guerrilla threat, and even staged attacks to be blamed on guerillas and used frozen dead bodies of guerilla fighters that had been kept in storage for this purpose. In late 1979, Amnesty International accused the Videla military government of being responsible for the disappearance of 15,000 to 20,000 Argentine citizens since the 1976 coup. That year, a special study by the New York City Bar concluded that around 10,000 Argentines had disappeared since the coup. According to "Registro Unificado de Víctimas del Terrorismo de Estado" (Ruvte), 662 were disappeared under the presidency of Isabel Perón and 6,348 were disappeared during the military dictatorship.
