The Unit is organized in accordance with the European standards for Special Police Units, so that its structure and unit strength provide quality training and high operability level in performing certain tasks.
Everybody who wishes to become a member of Special Anti-Terrorist Unit has to go through rigorous and difficult selective training. The contest for accepting new candidates depends on the needs of the Unit and available job posts. Training of future members is based on the experiences of home and foreign specialized units and is harmonized with the universally accepted world standards and trends. In accordance with the strictly purposeful needs, the aim of Special Anti-Terrorist Unit training is to professionally train, drill, and prepare all the members of the operational unit both physically and mentally to successfully perform the most complex and delicate tasks in all situations and in every moment.
Ever since it was established to this day, the Special Anti-Terrorist Unit has been continuously developed and modernised and the process can be divided into three stages:
� First stage (from 1992 to 1995);
� Second stage (from 1995 to 2001);
� Third stage (from 2001 to today)
With the outbreak of war conflicts in Bosnia and Herzegovina, the members of the Bosnia and Herzegovina Ministry of the Interior divided based on their ethnicity, so on 4 April 1992, the Police Unit for Special Actions was also divided, and in the second half of 1992, the Special Police Brigade was formed. In the period of war conflicts, from 1992 to 1994, nine units were formed with brigade command stationed in the village of Janja, BIH. Formation structure was as follows: Command, I � Pale division, II � �ekovi�i division, III � Trebinje division, IV � Bijeljina division, V � Doboj division, VI - Banja Luka division, VII � Prijedor division, VIII � Ilid�a division, and IX � Fo�a division. During the war, the Special Police Brigade had 1,500 members, and 144 of them gave their lives for the Republic of Srpska and 400 members were injured. On multiple occasions, the Unit was decorated with the orders of Petar Mrkonji�, Nemanji�i, the First of Order of Njego�, and the order of Merits for the People. Certain number of Unit members was decorated with the orders of Milo� Obili� and Milan Tepi� and other decorations.
From 1995 to 2001, the whole Brigade completely changed under detailed monitoring of international organisations, primarily IPTF. When Dayton Peace Agreement was signed, and since its Annex 1B provided that special formations had to be disbanded and retreated to bases/barracks, the Unit changed its name into Anti-Terrorist Actions Police Brigade. The Annex 11 to Dayton Peace Agreement provided that members had to go through training under control of international police � IPTF. After reorganisation in 1998, the Unit got a new name � Specialised Police Service with the Command in Janja, near Bijeljina, divisions in Prijedor and Ilid�a were disbanded, and divisions in Trebinje and Fo�a were integrated with the base on Tjenti�te. Other divisions were transformed into specialised teams. After the reorganisation 1999/2000, the Specialised Police Service was dislocated from Janja to Banja Luka. All divisions were disbanded with exception to those in Janja and Banja Luka. The Specialised Team was located in Banja Luka and transformed into Anti-Terrorist Team.
In 2001, the division Janja was disbanded, and in Rakova�ke Bare base, near Banja Luka, the Specialised Police Service continued their activities, and parts of it were Anti-Terrorist Team, Specialised Team and Mechanised Team. In 2004, the Service changed its name into Special Police Unit. On 8 August 2016, when the Rulebook on internal organisation and systematisation of job posts in the Republic of Srpska Ministry of Interior entered into force, the Unit changed its name into Special Anti-Terrorist Unit. Since the establishment of the Police Brigade in 1992 until today, the duty of Commander was performed by the following people: 1. Milenko Kari�ik (1992-1993); 2. Goran Sari� (1993-1997); 3. Du�ko Jevi� (1997-1999); 4. Dragan Luka� (1999-2004); 5. Ranko Vukovi� (2004-2006); 6. Predrag Krajnovi� (2006-2015); 7. Dragan Ribi� (2015 -2018); 8. Goran Balaban (2018-).
