Las Fuerzas Armadas de la Resistencia Nacional (National Resistance Armed Forces) was the military arm of National Resistance, a Salvadoran communist organization that was founded on May 10, 1975 when ideological differences within the ERP (Ejército Revolucionario del Pueblo) and the assassinations of Roque Dalton and Armando Arteaga made some members break away from the ERP. Ernesto Jovel was its first general secretary. Other founding members of the RN included Eduardo Sancho (aka Fermán Cienfuegos), Lil Milagro Ramírez, Julia Rodríguez and Arsenio.
