This research presents two dimensions on which post-communist NATO members can be divided, and dives into the question how much these variables affect troop contribution to NATO-led operations in Afghanistan. By collecting data from different public sources, a clear visual and numerical image will be created of the troop contribution and modernisation of defence for four different clusters of countries. Results show that post-communist nations overall contribute more to these military operations, but that not every group is equal in terms of how many troops are contributed. Modernised armies are in general less likely to contribute troops, while countries that have a higher domestic and regional threat perception are more avid to fight for their NATO security guarantee.Show less
