In 1989, the MRTA set up the 'Róger López' military detachment in the Medio Mayo zone, with an area of influence on the banks of the Mayo River, in the province of Lamas, San Martín. This detachment was part of the eight control zones established by MRTA's Northeastern Front.
In 1989, the MRTA established the military detachment called 'Róger López' in the area of Medio Mayo, as part of the expansion and territorial reorganization of the Northeastern Front. This detachment had as its area of influence the banks of the Mayo River in the province of Lamas. It was part of the eight zones controlled by the MRTA in the department of San Martin, as a result of the expansion of the theater of operations and the decentralization of the Tupacamarista Army. The creation of these zones and detachments allowed the MRTA to maintain greater control over military actions, evade the offensive of the Armed Forces and police, and prolong the armed confrontations in the region.
