The Counterintelligence Service or KOS (Serbo-Croatian: Kontraobav(j)eštajna služba; Контраобав(ј)ештајна служба; Slovene: Kontraobveščevalna služba; Macedonian: Контраразузнавачка служба) was the counterintelligence service of the Yugoslav People's Army (JNA) that existed between 1946 and the breakup of Yugoslavia in 1991. In 1992, the Security Administration continued its work in Serbia and Montenegro.
KOS was formed in 1946 as one of the remnants of the Department for Protection of the People (OZNA), with State Security Directorate (UDBA) forming the second, civilian, component of the new security and intelligence structure of SFR Yugoslavia.
Most information is still scant due to its classification as military secret, but some can be traced in the media, especially during the Milošević tenure and the role played in the break-up of SFRY (e.g. Operation Labrador and Operation Opera orientalis).
Yugoslavia (Serbo-Croatian, Macedonian, Slovene: Jugoslavija, Југославија) was a country in Southeast Europe during most of the 20th century. It came into existence after World War I in 1918 under the name of the Kingdom of Serbs, Croats and Slovenes by the merger of the provisional State of Slovenes, Croats and Serbs (itself formed from territories of the former Austro-Hungarian Empire) with the formerly independent Kingdom of Serbia. The Serbian royal House of Karađorđević became the Yugoslav royal dynasty. Yugoslavia gained international recognition on 13 July 1922 at the Conference of Ambassadors in Paris. The country was named after the South Slavic peoples and constituted their first union, following centuries in which the territories had been part of the Ottoman Empire and Austria-Hungary.
Renamed the Kingdom of Yugoslavia on 3 October 1929, it was invaded by the Axis powers on 6 April 1941. In 1943, a Democratic Federal Yugoslavia was proclaimed by the Partisan resistance. In 1944, the king recognised it as the legitimate government, but in November 1945 the monarchy was abolished. Yugoslavia was renamed the Federal People's Republic of Yugoslavia in 1946, when a communist government was established. It acquired the territories of Istria, Rijeka, and Zadar from Italy. Partisan leader Josip Broz Tito ruled the country as president until his death in 1980. In 1963, the country was renamed again as the Socialist Federal Republic of Yugoslavia (SFRY).
1554 Yugoslavia, provisional designation 1940 RE, is a stony asteroid from the middle region of the asteroid belt, about 17 kilometers in diameter. It was discovered by Serbian astronomer Milorad Protić at Belgrade Astronomical Observatory, Serbia, on 6 September 1940.
The asteroid is a member of the Eunomia family, a large group of S-type asteroids and the most prominent family in the intermediate main-belt. It orbits the Sun at a distance of 2.1–3.1 AU once every 4 years and 3 months (1,547 days). Its orbit shows an eccentricity of 0.20 and is tilted by 12 degrees to the plane of the ecliptic. It has a well-defined rotation period of 3.89 hours, measured by several photometric light-curve observations. Based on measurements by the Japanese Akari satellite and the Wide-field Infrared Survey Explorer, the body's albedo is inconclusive – ranging from 0.07 to 0.27 – while the Collaborative Asteroid Lightcurve Link (CALL) assumes an albedo of 0.21, typical for stony asteroids.
