Mandate and functions The UNCRO mission was established under Chapter VII of the United Nations Charter. It was initially scheduled to end on 30 November 1995, and its mandate was to support implementation of a ceasefire agreed to by Croatia and the RSK on 29 March 1994, as well as an agreement on economic cooperation made on 2 December 1994. The former entailed monitoring areas between HV and ARSK forward positions, verification that specific types of heavy weapons were at least away from the forward military positions or placed in storage, maintenance of checkpoints, chairing Joint Commissions, and performance of liaison functions. The economic functions were supporting negotiation and implementation of further economic arrangements and facilitating and supporting activities aimed at opening of transport routes and power and water supply networks. UNCRO was also tasked with delivery of humanitarian aid and control, monitoring, and reporting of any transport of military personnel, supplies, equipment, or weapons across UNCRO-staffed border checkpoints between RSK-held parts of Croatia on one side and Bosnia and Herzegovina or the Federal Republic of Yugoslavia on the other. The mandate also directed UNCRO to monitor demilitarisation of the Prevlaka Peninsula at the entrance to the
Bay of Kotor, according to the
UNSC Resolution 779. The mission was scheduled to be scaled down in June to 8,750 troops from the larger UNPROFOR force in the country. UNCRO was criticised for several reasons. The Secretary-General's Report to the Council described the failures of UNPROFOR, but the new mission did not address them. There were insufficient troops, having been reduced from UNPROFOR levels by the new mission mandate, and inadequate human and material resources to carry out the mission tasks. As a result, fulfilment of the mission mandate was nearly impossible. Conversely, Croats were pleased that the mission acronym appeared to be an abbreviation of
Croatia. In response, Czech UNCRO troops used vehicle licence plates bearing the new mission's acronym when operating in HV-controlled territory and UNPROFOR plates in areas held by the ARSK due to safety concerns.
Order of battle UNCRO was commanded from UN Peace Force Headquarters (UNPF-HQ) established in
Zagreb. UNPF-HQ controlled UNCRO, the
United Nations Preventive Deployment Force (UNPREDEP) in the Republic of Macedonia, and UNPROFORwhich was confined to Bosnia and Herzegovina from late March. The UNPF-HQ commander was French Lieutenant General
Bernard Janvier. In July, South Korean diplomat Byung Suk Min was appointed as head of UNCRO, with Major General Eid Kamal Al-Rodan of the
Royal Jordanian Army as the mission's military commander. Before Al-Rodan, the post was held by Canadian Lieutenant General
Raymond Crabbe. UNCRO was initially deployed to the same parts of Croatia as UNPROFOR, however contemporary UNSC documents no longer referred to them as UNPAs—applying the designations of Sector East, West, North, and South, or "areas under the control of the local Serb authorities" instead. One group of sources refers to the areas of UNCRO deployment as UNPAs, another reflects the UNSC practice and omits the acronym, while others refer to the areas as "former UNPAs".
Response to Croatian offensives On 1 May, HV launched
Operation Flash and overran the ARSK-held part of Sector West in the course of few days. Šarinić warned Crabbe of the attack hours in advance to allow UNCRO troops to seek shelter. Nonetheless, UNCRO did not stop ARSK troops from retrieving the weapons. During the fighting, ARSK troops took 15 UNCIVPOL members, two interpreters, and 89 Nepalese and Argentinean troops hostage to use as human shields against the HV. HV troops hijacked an UNCRO armoured personnel carrier and a Land Rover to precede HV tanks that were moving west along the
A3 motorway. On 3 May, the Argentinean battalion of UNCRO facilitated the surrender of 600 ARSK troops near Pakrac, following an agreement reached between Croatia and the RSK which was mediated by
Yasushi Akashi, the personal representative of the UN Secretary-General. During Operation Flash, three Jordanian UNCRO troops were wounded by HV fire. On 4 August, the HV initiated
Operation Storm, which was aimed at recapturing Sectors North and South, which encompassed the bulk of the RSK. UNCRO was notified three hours in advance of the attack, when Šarinić made a phone call with Janvier. In addition, each HV corps notified the UNCRO sector in the path of its planned advance, and requested written confirmation that the information had been received. UNCRO relayed the information to the RSK authorities. Two days later, UNCRO was requested to protect 35,000 Serb civilians accompanying the ARSK as it retreated towards Bosnia and Herzegovina. They were trapped near
Topusko when HV troops captured
Glina, closing the last road available to them. The UNCRO Ukrainian battalion base was used as a venue for negotiations for the surrender of the trapped ARSK Kordun Corps; the negotiations were conducted in the presence of UNCRO officers. The commander of UNCRO Sector North signed the surrender agreement as a witness. This offensive also involved actions against UN peacekeepers; the
Army of the Republic of Bosnia and Herzegovina, which supported the offensive from the
Bihać pocket, attacked UNCRO observation posts defended by Polish troops, while HV troops used several Danish peacekeepers as human shields. During the offensive, ARSK detained five Sector East headquarters staff, several UNCRO vehicles were hijacked, and UN personnel were harassed. Four UN peacekeepers were killed in the offensivethree as a result of HV actions, and one as a result of ARSK fireand 16 were injured. HV troops also destroyed 98 UN observation posts. Following the two offensives and negotiations led by Akashi, UNCRO continued to supervise the ceasefire in Sector East. By November 1995, UNCRO had withdrawn to Sector East. Even though the UN had planned to reduce UNCRO to 4,190 troops by the end of September, and to approximately 2,500 by October, the mission strength remained at more than 7,000 troops until November. ==Termination and aftermath==
