Co-operation between civil society actors and military personnel is increasingly common in humanitarian missions since the early 1990s. However the interaction has led to varying degrees of friction between both groups, at times lessening the coordination and efficiency of the civil-military relationship. Existing theories of civilmilitary relations are largely based upon the relationship between the military and their civilian government, and have not been tested within the relationships experienced at the ground level during peace enforcement type missions. This study tests the theories of Samuel Huntington within the context o f the North Atlantic Treaty Organisation (NATO) led mission in Kosovo (KFOR) between 1999 and 2001. This period of time encompasses the NATO bombing campaign, including their interaction with civilian agencies during the refugee crisis, and the subsequent deployment of KFOR into Kosovo. The study examines KFOR’s interaction with various civilian entities including NGO’s, police forces, civilian administration, political and paramilitary figures. The methodological framework o f the study uses hypotheses generated from the work o f Huntington, and then tests the hypotheses with reference to KFOR’s actions and interactions with civilian entities. The thesis concludes that Huntington’s theory, with some qualifications, can successfully account for interaction in such an environment.
