Page "History of Guatemala" Paragraph 46

Four principal left-wing guerrilla groups — the Guerrilla Army of the Poor ( EGP ), the Revolutionary Organization of Armed People ( ORPA ), the Rebel Armed Forces ( FAR ), and the Guatemalan Party of Labour ( PGT ) — conducted economic sabotage and targeted government installations and members of government security forces in armed attacks.

These organizations combined to form the Guatemalan National Revolutionary Unity ( URNG ) in 1982.

At the same time, extreme right-wing groups of self-appointed vigilantes, including the Secret Anti-Communist Army ( ESA ) and the White Hand ( La Mano Blanca ), tortured and murdered students, professionals, and peasants suspected of involvement in leftist activities.
