Tito Biel Chuor (or Chol, Chor) was a high-ranking commander in the South Sudan Defense Forces (SSDF) during the Second Sudanese Civil War (1983–2005).
[3] Tito was pushed out of Leer by Paulino's forces, and on arrival in Yirol early in May 1999 he formally declared that he had switched to the SPLA, along with his officers and men.
[5] Riek Machar resigned from the government at the end of the year and in February 2000 formed the Sudan People's Defense Forces/Democratic Front (SPDF).
For a while the UMCC and SPDF cooperated, but the arrangement broke down as the government supplied Machar with arms and ammunition to settle grievances with the SPLA/Gadet troop.
[7] In early 2001 Tito Biel returned to Eastern Upper Nile with Riek Machar where they tried to drum up support for the SPDF militia.
