In February 2014, after Koang was given command of anti-government forces in Unity State, those forces attacked United Nations camps, hospitals, churches, and schools, engaging in widespread rape, torture, and the destruction of property, in an attempt to flush out civilians, soldiers, and policemen allied with the government.
À la mi-septembre 2014, Koang aurait ordonné à ses forces de prendre pour cible des civils Dinka lors d'une attaque dans l'État du Haut-Nil.
