Kumba was 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
Alliance of Democratic Forces for the Liberation of Congo (AFDL) in 1996. During the
Second Congo War, Amisi was assistant chief of staff for logistics of the
Rally for Congolese Democracy (RCD-G). This position was the origin of his nickname, as T-4 was the abbreviation for his position. He was implicated by
Human Rights Watch in the execution of soldier Joe Lona Bifuko and in the torture of prisoners in the ANC military intelligence detention centre in
Goma in 2001. Amisi repressed of a mutiny in
Kisangani in May 2002. Amisi was the former commander of the 8th Military Region in
North Kivu, appointed in January 2005. In August 2006, it appears he was moved from command of the 8th Military Region to become chief of staff of the
FARDC Land Forces (Forces Terrestre). There are credible allegations, some made by the
BBC, that General Kumba personally profited from his position, benefiting from mining in the east of the country, during the past few years. Many reports link Amisi to mining operations in North Kivu. In particular, he 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. On 22 November 2012, Amisi was suspended from his position in the
Forces Terrestres by president
Joseph Kabila due to his alleged role in the arms sales to rebel groups in the eastern part of the country, which may have implicated the rebel group
M23. In 2017, a UN report alleged that Amisi was mining gold on the Awimi River in
Tshopo province, and that the management of La Conquete, a company he allegedly owns, were guarded by Congo’s military (FARDC).{{cite web ==References==
