is estimated that one-third of RENAMO forces were child soldiers. But abducted people also had to serve RENAMO in administrative or public service functions in the areas it controlled. Another way of using civilians for military purposes was the so-called system of "Gandira". This system especially affected the rural population in areas controlled by RENAMO, forcing them to fulfill three main tasks: 1) produce food for RENAMO, 2) transport goods and ammunition, 3) in the case of women, serve as sex slaves. RENAMO's stated goal was to free Mozambique from "Machelist Communism". RENAMO's political programme centered around the abandonment of FRELIMO's socialist policies, the adoption of a free market economy, and more traditionalist concerns such as the reinstatement of tribal leaders to positions of authority. Thus, despite its far superior numbers, FRELIMO was unable to adequately defend most regions except the most important cities by the mid-1980s. RENAMO was able to carry out raids virtually anywhere in the country except for the major cities. Transportation had become a perilous business. Even armed convoys were not safe from RENAMO attacks and were frequently attacked. FRELIMO strategies and operations FRELIMO reacted by reusing a system similar to the fortified villages aldeamentos introduced by the Portuguese: the creation of fortified communal villages called aldeamentos comunais where much of the rural population was relocated as the war intensified. Furthermore, in order to keep a minimum level of infrastructure working, three heavily guarded and mined corridors were established consisting of roads, railways and power lines: the Beira, the Tete (also called the Tete Run which speaks for itself regarding its safety) and the Limpopo Corridor. Despite extensive fortification along these corridors they were frequently subject to attacks, bombings of the railway line and locomotives along the Beira Corridor cost the FRELIMO government millions as it struggled to provide adequate food and services and put strains on its ally Zimbabwe. Foreign support and intervention FRELIMO initially received substantial military and development aid from the Soviet Union and East Germany but later received support from France, the UK and the U.S. In the U.S., conservative circles lobbied for the U.S Government to provide open support to RENAMO but were opposed by the State Department, which finally gained the upper hand following the publication of numerous, detailed reports which documented RENAMO's brutality. RENAMO received extensive military and logistical support from Rhodesia and South Africa as well as organisational
