Chetniks
Chetniks, or the Chetnik movement (Serbo-Croatian: Četnici, Четници, ; Slovene: Četniki), were a Serb nationalist and monarchist paramilitary organizations from the first half of the 20th century, formed as a resistance against the Ottoman Empire in 1904, and participating in the two Balkan Wars, World War I, and World War II. Between the wars, in the Kingdom of Yugoslavia, they functioned in the form of two civilian organizations. The name is today most closely associated with the Chetnik Detachments of the Yugoslav Army, the World War II movement of Draža Mihailović, which was later renamed the Yugoslav Army in the Homeland (Jugoslovenska vojska u otadžbini, Југословенска војска у отаџбини; JVUO, ЈВУО), though the original name remained more common. The Mihailović Chetniks were not a homogeneous movement.
