Operation Winter '94 (Serbo-Croatian: Operacija Zima '94, Операција Зима '94) was a joint military offensive of the Croatian Army (HV) and the Croatian Defence Council (HVO) fought in southwestern Bosnia and Herzegovina between 29 November and 24 December 1994. The operation formed part of the Croatian War of Independence and the Bosnian War fought between Bosnia and Herzegovina, Croatia and two unrecognized para-states proclaimed by Croatian Serbs and Bosnian Serbs. Both para-states were supported by the Yugoslav People's Army (JNA) and Serbia. The JNA pulled out in 1992, but transferred much of its equipment to the Bosnian Serb and Croatian Serb forces as it withdrew.
