In 1977 there were incidents of unrest in Thailand of an unusual nature including serious crimes and international terrorism. Pol.Col. Chumpon Attasat Superintendent of the Riot Control and Suppression Sub-Division had established a special operation unit called "Anti-Hijacker". He has selected police officers within the unit who were physically, mentally, and intellectually ready to the specified qualifications to attend the training in order to cater to missions of the international nature. During the training, there was no financial support not even for the meals of the attendees. Therefore, participants joined in this training with their hearts and ideologies. After Pol.Col.Chumpon Attasit was assigned to take a position in a different unit the special operation had changed.
In 1983 There was an international terrorism incident and insurgency in Thailand, particularly in Bangkok. Pol.Maj.General Thip Asawarak Commander of Patrol and Special Operations Division at that time had resurrected the special operation unit. He requested the Royal Thai Police department for the authorization of an international training plan for the special operation unit similar to GSG9 in Germany. Later in 1984, The Royal Thai Police department ordered the establishment of a special operation unit within the Metropolitan Police Bureau, using the name of special operation unit "Arintaraj 26"
