Having fought the Portuguese using guerrilla strategies, FRELIMO was now forced to defend itself against the very same methods it employed against the colonial regime. It had to defend vast areas and hundreds of locations, while RENAMO operated out of a few remote camps, carrying out raids against towns and important infrastructure. Furthermore, RENAMO systematically forced civilians into its employment. This was done by mass abduction and intimidation, especially of children in order to use them as soldiers. It 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. Despite RENAMO'S alleged goals of freeing Mozambique from 'Machelist Communism' RENAMO never established a political program that proposed an alternative to FRELIMO, nor anyone in the role of a political leader throughout the war.
