FK Naša Krila Zemun
FK JRV Naša krila (Serbian Cyrillic: Наша крила; lit. "Our Wings"; commonly referred to as Naša krila Zemun or just Naša Krila) was a short-lived Yugoslav football club established in 1947 as a section of the eponymous sports society affiliated with the Yugoslav Air Force (JRV). Based in Zemun, SR Serbia, the club acted as the Air Force's official team, and relied on players serving their mandatory military service with the branch, also headquartered at Zemun.
Despite being active for only a few years, before being disbanded in 1950, the club was very successful in domestic football during its existence. In their first competitive season in 1947–48 they won promotion to Yugoslavia's top league, and went on to finish fifth in the 1948–49 and sixth in 1950. They also reached two Marshal Tito Cup finals (1947, 1949) and one semi-final (1948).
