This study analyses modes of control territory in conflict areas such as the Balkans, as well as other regions, where international security forces (military and police) have a specific mandate to support a government and ensure a safe and secure environment. This kind of control is necessary where political sovereignty is exercised on behalf or under the auspices or supervision of the international community by a transitional authority or by a local government troubled with stability problems. This contribution cannot take place during open hostilities or in a situation in which the military forces act as occupying power. In those situations we assume that the military forces have the authority and the obligation to exercise full control of the security factors for a determined period of time according to the needs and laws of war. During the occupation, according to International Humanitarian Law, the “de facto” control of the whole territory or part of it exercised by military forces is sufficient to oblige them to take over the responsibility to protect the civilian population, ensure the survival and the basic rights of the citizens, protect and carefully manage the resources of the country.
