Suharto relied on the military to ruthlessly maintain domestic security , organized by the Kopkamtib ( Operation Command for the Restoration of Security and Order ) and BAKIN ( State Intelligence Coordination Agency ) . To maintain strict control over the country , Suharto expanded the army 's territorial system down to village-level , while military officers were appointed as regional heads under the rubric of the '' Dwifungsi '' ( " Dual Function " ) of the military . By 1969 , 70 % of Indonesia 's provincial governors and more than half of its district chiefs were active military officers . Suharto authorized '' Operasi Trisula '' which destroyed PKI-remnants trying to organize a guerilla base in Blitar area in 1968 , and ordered several military operations which ended the communist PGRS-Paraku insurgency in West Kalimantan ( 1967 – 1972 ) . Attacks on oil workers by the first incarnation of Free Aceh Movement separatists under Hasan di Tiro in 1977 led to dispatch of small special forces detachments who quickly either killed or forced the movement 's members to flee abroad . Notably , in March 1981 , Suharto authorised a successful special forces mission to end hijacking of a Garuda Indonesia flight by Islamic extremists at Don Muang Airport in Bangkok
