LtCol Wioyotomo Nugroho
Commander of the Combined Intelligence Task Force (Satuan Gabungan Intelijen, SGI), Dili
According to a report by David Jenkins, Nugroho was at the centre of East Timor operations until about December 1998 or January 1999, taking an active role in setting up the militias. One source says that he was reassigned to Jakarta early in 1999.
SGI ran a series of interrogation centres much feared by East Timorese activists for the torture it conducted, among other counter-insurgency activities. Almost nothing is known of who staffed the SGI. Other officers named as SGI 'commanders' in 1999 are LtCol Yayat Sudrajat and Col Anwar. Yet another is Capt Siburian.
Wioyotomo Nugroho graduated from the military academy in 1983 and is known to have taken two training courses in the US funded by IMET (International Military Education and Training), the first in intelligence while he was a captain, the second possibly in airborne combat.
David Jenkins lists him as 'Kopassus intelligence chief', but given his rank of Lieutenant Colonel this is more likely to mean that he was assistant for intelligence to the commander-general of Kopassus (Asintel Danjen Kopassus) rather than commander of Kopassus' Group IV (Intelligence/ Secret Warfare) . He may have doubled in this position as Commander of the Combined Intelligence Task Force (Satuan Gabungan Intelijen, SGI) in East Timor, a position he apparently held since at least June 1998. Some time in 1999 he took up a position in personnel in Kopassus.
