The Obote government's four-year military effort to destroy its challengers resulted in vast areas of devastation and greater loss of life than during the eight years of Amin's rule. UNLA's many Acholi and Lango had been hastily enrolled with minimal training and little sense of discipline. Although they were survivors of Amin's genocidal purges of north-east Uganda, in the 1980s they were armed and in uniform, conducting similar actions against Bantu-speaking Ugandans in the south, with whom they appeared to feel no empathy or even pity.
