Аннотация:The article is based on research conducted at the Defence Research Centre, emphasizing the qualitative data gathering conducted among members of the Slovenian Armed Forces (SAF) in the UN Interim Force in Lebanon (UNIFIL II) mission in 2007–09. Complex peace operations, as opposed to traditional ones, require a multinational structure and cooperation with several non-military actors/subjects. Trying to be effective, doing the job as well as possible and surviving the situation of living in a limited area with formal and informal interaction with a small number of people takes well-defined rules and procedures as well as the awareness of the importance of integrating mechanisms. Culture, encompassing the military organizational culture as well as the so-called ‘national culture’, undeniably has a substantial impact on the relations within a given multinational operation. Within the cultural framework, the common language or lingua franca deserves special attention.
