At the beginning of the war, the Croatian government helped arm both the Croat and Bosniak forces. Logistics centres were established in Zagreb and Rijeka for the recruitment of soldiers for the ARBiH. The Croatian National Guard (Zbor Narodne Garde, ZNG), later renamed officially to Croatian Army (, HV) was engaged in Bosnian Posavina, Herzegovina and Western Bosnia against the Serb forces. During the Croat-Bosniak conflict, the Croatian government provided arms for the HVO and organised the sending of units of volunteers, with origins from Bosnia and Herzegovina, to the HVO.
