Major General Gabriel Amisi Kumba (Tango Four) is Chief of Staff of the Forces Terrestres, the army of the Democratic Republic of the Congo. Amisi was a former Forces armees Zairoises (FAZ) officer who was recruited into the AFDL in 1996.[1] During the Second Congo War, Amisi was assistant chief of staff for logistics of RCD-G. He became famous for for helping command the repression of a mutiny in Kisangani in May 2002.[1] This position was the origin of his nickname, as T-4 was the abbreviation for his position. He was former commander of the 8th Military Region in North Kivu. There are credible allegations, some made by the BBC, that General Kumba has personally profited from his position, benefiting from mining in the East of the country, during the past few years.[2]
There have been many reports linking Amisi to mining operations in North Kivu. In particular, Amisi appears to have protected and profited from the operations of Colonel Samy Matumo, the former commander of the 85th Brigade that occupied the Bisie mine for several years.[1]
