Komando Pasukan Khusus Special Unit: Satuan 81 Penanggulangan Terror / SAT-81 GULTOR (Anti Terror Unit 81)

To anticipate the increase in potential airplane hijacking cases in the 70s and 80s, the head of Indonesian Army Strategic Intelligence Office (BAIS) formed a new detachment in the Army Special Forces (then Kopassandha). On June 30, 1982, the new unit, called Detasemen 81 (Den-81) Kopassandha, was formally established with Major Luhut B. Panjaitan as its first commander and Captain Prabowo Subianto as its first vice commander. Both of these officers had been sent to Germans GSG-9 (Grenzschutzgruppe-9) school to learn about the anti-terror techniques. These two officers then selected and trained the Den-81 troops.

The desire to form Den-81 was mostly motivated by the hijacking incident of Garudas DC-9 Woyla in Don Muang Airport, Bangkok-Thailand, on March 31, 1981. The troops that involved in the operation to free Woyla became the first troops in Den-81. Later, Den-81 was changed into Unit-81 Anti-Terror (Sat-81 Gultor). From 1995-2001, Den-81 became the Group 5 Antiterror (Groups 4 Sandhi Yudha) in the Kopassus (new name for Army Special Forces) structure.

Sat-81 Gultor is under the direct command of Kopassus commander in chief. Currently, this unit is led by a colonel. The recruitment process of this unit starts when the troops finish the Para and Commando programes in Batujajar, West Java. From here, they will be assigned to Group 1 and Group 2 of Kopassus for orientation or gaining combat experience. After returning from these assignments, these troops will be evaluated for further assignment to the Anti-terror unit. The Anti-terror program is conducted in Special Combat Training School in Batujajar, West Java.

The most recent successful operation conducted by Sat-81 Gultor is the rescue of 26 hostages from Kelly Kwaliks terrorist group in Irian Jaya on May 15, 1996. However, Operation Woyla is still the biggest and internationally well-known operation that Indonesain Army ever experienced.

Currently, there is no exact information of the number of troops in Sat-81 Gultor.
