In 1992, elements of the Zrinski Battalion took part in the Battle of Kupres, before setting up a training camp in the town of Tomislavgrad. There the battalion personnel assisted in setting up and trained the Croatian Defence Council ("Hrvatsko vijeće obrane" – HVO). Later that year, elements of the battalion took part in Operation Tiger—aimed at lifting of the Siege of Dubrovnik. In 1993, elements of the Zrinski Battalion took part in Operation Maslenica, fighting in the area of Škabrnja. The Central Intelligence Agency assessed the Zrinski Battalion as one of the best units of the HV.
