MajGen Mahidin Simbolon
Chief of Staff, Udayana command (Kasdam Udayana)
One of Mahidin Simbolon's jobs as chief of staff in Udayana military area, based in Bali but which included East Timor, was probably to provide logistical support for the East Timor militias.
Leaked Australian communications intercepts prove that Simbolon had close contacts with the militias. On 14 February 1999, militia leader Eurico Guterres phoned the Kopassus unit Tribuana to report on the condition of an injured member of the Mahidi militia. He was told: 'We know that Brig-Gen Simbolon is concerned that one of his crew is injured.' Mahidin Simbolon was close to Mahidi militia leader Cancio de Cavalho, who coined the name for his group as a tribute to the Indonesian officer.
On 12 May Simbolon attended a meeting at the Dili military headquarters with East Timor commander Tono Suratman and militia commander Joao Tavares.
His six assistants were all called to testify at KPP HAM hearings in December 1999. The given reason (for all except Col Endang Riswanda) was that they had been part of the Udayana tactical command (Komando Taktis Kodam Udayana) in the framework of the referendum in East Timor. They were:
Assistant for Logistics (Aslog Kasdam IX/Udayana)
Assistant for Operations (Asops Kasdam IX/Udayana). Born in about 1951, he graduated from the military academy in Magelang in 1974. In October 2000 he was appointed to head up the military command for West Timor (Korem 161/Wirasakti) based in Kupang, where he took special action to secure the border with East Timor. Besides having to handle East Timorese refugees angry over having lost their property in East Timor, and running a less-than-successful weapons buy-back scheme from militias, he faced local opposition to the expanded military presence he was building along the border. A new military base for batallion 744 was intended (he said) 'to anticipate disturbances from a foreign country whose ideology is different to that of Indonesia'.
Assistant for Intelligence (Asintel Kasdam IX/Udayana). He was afterwards promoted to BrigGen and in 2002 was a sub-area commander (danrem) in East Java.
- Col (Inf) Endang Riswanda
Assistant for General Planning (Asrena Kasdam), Kodam IX/Udayana). Born in about 1949, he graduated from the military academy in 1972.
Assistant for Territorial Affairs (Aster Kasdam IX/Udayana). Born in about 1951, he graduated from the military academy in 1974.
- Col I Ketut Redeng Warjana
Personal Assistant (Aspers Kasdam IX/ Udayana, serial no. 25379)

He later took over the East Timor command (1995-97), after Kiki Syahnakri.
