History
Development of unit it is possible to split into three stages: first stage (1992–1995), second stage (1995–2001) and third stage (2001–today). Special Anti-Terrorist Unit of Ministry of Republika Srpska was founded on April 4, 1992 as Special Police Brigade (Специјална бригада полиције). During the War in Bosnia and Herzegovina it was a unit that fought in many battles. In that time, brigades command was in Janja near Bijeljina and unit was divided on nine battalion-sized detachments : Every detachment was capable to be independent on battle field because of its organisation. Detachment had three special infantry platoons, armored-mechanized platoon, mortar, logistic and communication platoon. The brigade numbered around 1,400 fighters, of whom 144 were killed and about 400 wounded. Second development stage is considered for peace time when command was in Janja and when brigade was renamed into Specialized Police Service (Служба специјализоване полиције). Two detachments were disbanded (Prijedor and Ilidža) and Trebinje and Foča detachments were integrated into Tjentište base. Later all detachments except Janja and Banja Luka were disbanded and in Banja Luka was formed Anti-Terrorist Team. Third stage is stage in whom units command was dislocated in Rakovačke Bare in Banja Luka. Specialized Police Service was organized on three teams: Anti-Terrorist, Specialized and Mechanized. On 2004 service changed name into Special Police Unit (Специјална јединица полиције or СЈП) and next year base was moved in central base "Sarica" in Trn near Banja Luka. In 2016, the unit assumed its current name and its headquarters were moved to Zalužani.
