Gabriel Gatwech Chan (1960 – 5 January 2017), more commonly known by the nickname Tang-Ginye or Tanginye meaning "long pipe", was a Nuer and a commander in various primarily Nuer rebel militias in South Sudan. General Tanginye led a southern border militia allied to the Khartoum government during Sudan's civil war. Members of the Sudanese armed forces loyal to Gen Tang in Malakal clashed with the Sudan People's Liberation Army (SPLA) in 2006, killing about 150 people, and in 2009 in breach of the peace deal. In April 2011, clashes between his militia and the SPLA in the state of Jonglei killed at least 57 according to government officials. Shortly thereafter, Tanginye surrendered to SPLA forces and was placed under house arrest in Juba awaiting charges against him. During the South Sudanese Civil War, he allied with the SPLA-IO and later Lam Akol's militia, a Juba linked rebel group called the National Democratic Movement (NDM) and became its chief of staff. In January 2017 he visited a NDM-allied group, the Tiger Faction New Forces, in the Hamra area in the northern Upper Nile. In course of this visit, the Tigers were attacked by SPLM-IO-affiliated fighters belonging to the militia of John Uliny, and Tanginye was killed alongside most of the Tigers.
