TheSecurity Directorate, best known by the acronymKOS (which is derived from the organization's original name in theSerbo-Croatian:Kontraobaveštajna služba - "Counterintelligence Service"), was the national military intelligence and security service of theYugoslav People's Army (JNA) that existed from 1946 until thebreakup of Yugoslavia in 1991. In 1992, theSecurity Directorate continued its work inSerbia and Montenegro.[citation needed]
The Counterintelligence Service (KOS) was formed in 1946 as one of the remnants of theDepartment for Protection of the People (OZNA), withDirectorate for State Security (UDBA) forming the second component of the new security and intelligence structure ofSFR Yugoslavia.[1] In 1955, it changed its name toSecurity Directorate (Uprava bezbednosti) and relocated from the General Staff to State Secretariat of People's Defence, laterFederal Secretariat of Peoples Defence.[citation needed]
Most information is still scant due to its classification as military secret, but some can be traced in the media, especially during theMilošević tenure and the role played in the break-up ofYugoslavia (e.g.Operation Labrador).[2]
