This research represents an original approach, based on a set of international and national documents, as well as some unpublished documents from the Ministry of Defense of the Republic of Moldova related to the participation of Moldovan soldiers in peacekeeping missions. The current paper is focused on legal issues regarding the Moldovan military personnel participation in military operations. A significant role is attributed to the analysis of the participation in certain peacekeeping operations under the UN, OSCE and EU as well as NATO. Moldovan military personnel are deployed to conflict areas, particularly in: OSCE Special Monitoring Mission to Ukraine, Iraqi post-conflict humanitarian operation and rehabilitation “Operation Iraqi Freedom”, Kosovo Force (KFOR), The United Nations Mission in Kosovo (UNMIK), The United Nations Mission in Liberia (UNMIL), The United Nations Mission in Sudan (UNMIS), Peacekeeping operation in Bosnia and Herzegovina, NATO- led Stabilisation Force in Bosnia and Herzegovina (SFOR), EU military advisory mission in the Central African Republic(EUMAM). For the first time, a full list of all participants in these missions is given.
