The RKK has been one of the most brutal and active violent groups of the South Thailand insurgency in recent years.

The RKK was founded by young Salafi members of the Barisan Revolusi Nasional-Koordinasi (BRN-C) in 2000 that had received military training in Indonesia.

[citation needed] The RKK is based on well-trained, ruthless and effective commando style groups, named 'small patrol units' (Runda Kumpulan Kecil) after the description of their month-long military training course.

[1] Captured members have confessed to the Thai authorities that they routinely flee to Malaysia after carrying out violent attacks in Yala, Pattani or Narathiwat Province.

Although several RKK members have been arrested or killed by the Thai military or police in the past decade, it is very difficult for those involved in counterinsurgency to penetrate the structure of the group owing to its secrecy and great mobility.

[6][3] In July 2006, the Royal Thai Police (RTP) arrested two supposed members of the RKK, one of which was Sapee-aree Jekhor.

[10] On 18 November 2012 a train travelling through the City of Reuso (in the Narithiwat Province) derailed as a result of a bomb planted under the track.

[17] Seventeen suspects who were arrested by the Thai Police after the assassination of a Buddhist monk on 16 October 2005 claimed to have connexions with the RKK.

[3] The reports that followed the arrest stated that the insurgent group members had been trained at Muslim schools in Bandung, Indonesia.

[18] On 13 February 2013, an armed group of 60 men attacked a military base in the southern part of the country, 16 of whom were killed by the army.
