[1][2] In October 1994, the 5th Corps of the ARBiH, led by Atif Dudaković, launched a major offensive operation called "Grmeč 94".

The ARBiH forces, consisting of approximately 13,000 soldiers, advanced from the northern parts of the enclave, aiming to capture several key villages and the former base of the JNA in Grmeč.

Over the next few days, the ARBiH forces continued to advance, capturing more territory and pushing towards Bosanski Petrovac and Krupa na Una.

However, the Army of Republika Srpska chief of staff, Manojlo Milovanović, demanded that the United Nations condemn the Muslim offensive and return to their initial positions.

On October 28, the President of the Republika Srpska, Radovan Karadžić, declared a "state of war" in the zone of responsibility of the 2nd Krajina Corps of the VRS and mobilized all able-bodied men who could bear arms in that area.

[3][citation needed] The ARBiH corps achieved its greatest success since the beginning of the war on October 29-31, surrounding Krupa na Una and entering Kulen Vakuf.

However, on October 29, the VRS units prepared for defense of Krupa na Una and successfully repelled a Muslim attack.

[citation needed] Serbian general Manojlo Milovanović is given orders to liberate land lost to Bosnian forces during “Operation Grmeć 94”.
