The Croatian Defense Forces (HOS) were the military arm of the Croatian Party of Rights (HSP) from 1991 to 1992, during the first stages of the Yugoslav wars. During the Croatian War of Independence, the HOS organized several early companies and participated in Croatia's defense. At the peak of the war in Croatia, the HOS had several battalions in size. The first HOS units were headed by Ante Paradžik, a HSP member who was killed by Croatian police in September 1991. After the November 1991 general mobilization in Croatia and the January 1992 cease-fire, HOS was absorbed by the Croatian Army.

The HOS units in Bosnia and Herzegovina consisted of Croats, Bosniaks and foreign volunteers led by Blaž Kraljević. On 9 August 1992, Kraljević and eight staff members were assassinated by the Croatian Defense Council (HVO) soldiers under the command of Mladen Naletilić. The HOS was disbanded shortly afterwards, and absorbed by the HVO and the Army of the Republic of Bosnia and Herzegovina at the beginning of the Croat-Bosniak War. The last HOS unit was dissolved on April 5, 1993 in central Bosnia.
