This paper analyses the military behaviour of Russia from 1992 to 2010. The method used is a combination of the dyad analysis introduced by Stuart Bremer in 1992 and the analysis of unit-level variables, which is distinctive of foreign policy analysis. We empirically test a set of hypotheses about the determinants of Russia's military behaviour in the post-Cold War period by considering the impact of changes of international variables – relative power, the presence of military alliance pacts, the territorial salience of the dispute – and state-level variables – the degree of democracy/autocracy and regime vulnerability. A bivariate and a multivariate analysis are carried out to explain the separate and joint impacts of independent variables.
