and was active only in the NOVJ & PO (People's Liberation Army of Yugoslavia and Partisan Detachments). The fourth section performed statistical and technical tasks, processed information, and kept records. This section also included special photography, secret writing, radio centers, and decoders. A fifth and sixth section were formed in the OZNA in March and April 1945. The fifth section was formed as a counterintelligence service against foreign agent networks in Yugoslavia; that is, foreign intelligence services. (In 1946, this section merged with the new third section, which was created after the military counterintelligence service became independent). The sixth section performed tasks dealing with counter-intelligence protection of transportation, but was absorbed soon after its establishment by the second sector. Activities When the National Liberation Army changed its name into the Yugoslav Army (JA) on March 1, 1945, the OZNA of Democratic Federal Yugoslavia proclaimed by special directive (March 24, 1945) a new organization of the JA – OZNA. The OZNA was in direct command of counter-intelligence protection of military command posts, institutions, and units. Sections were set up within independent corps. This third OZNA section was in force until the end of July, 1945. The "military" and "civil" part of the OZNA began to separate in 1945 and split in March, 1946. At that time, the new splinter organizations, the Administrative Directorate for Security of JA – KOS (Kontra-Obaveštajna Služba) was formed from the military part and the Administrative State Security Directorate (UDBA) from its civilian counterpart. Since the OZNA was actually left without its third section after the military counter-intelligence service became independent, it formed a new third section unconnected to the previous one. It focused initially on reconstruction and operations of the German intelligence service (especially Gestapo). Later, the third section assumed operations for all foreign intelligence services, borders, and traffic of foreigners (which were essentially the tasks of the fifth section). The fourth section continued filing information they had been collected within the OF VOS since 1941. From initial information files on 4,000 people, by the end of the war the number had increased to 17,750. The OZNA was led by a chief who was directly subordinate to the Supreme Commander of the Yugoslav Army, Marshal Josip Broz Tito. Mass killings of the "enemies of the people" During the entire period of its existence, the OZNA used illegal practices which included occasional mass murders of the "enemies
