This study investigated whether ‘re-usable’ soldiers, that is, those who performed well during operations (military capacity), and were able to readjust postdeployment (civil adjustment), could be identified at predeployment. Participants were 364 UN peacekeeping soldiers. Three hypotheses were posed: the selection system for conscripts cannot identify soldiers with low military capacity (H: 1); the selection system for conscripts cannot identify soldiers with poor civil adjustment after deployment (H: 2); and the two aspects of ‘re-usability’ (military capacity and civil adjustment) would be intertwined (H: 3). Results showed that the selection system for conscripts was unable to identify soldiers' military capacity and civil adjustment. Results also showed that these two aspects were unrelated, and did not interact. Indications on possible consequences and improvements are discussed.
