Corruption in the defence sector diminishes public trust, reduces military effectiveness, and damages the legitimacy of the state. In Ukraine, high levels of corruption are having an impact in the conflict in the East. Despite some reform efforts, tackling corruption remains a vital need. Drawing on the findings of the Government Defence Anti-Corruption Index 2015, published by Transparency International, this paper examines the main corruption risks facing the Ukrainian defence establishment. It identifies policy and budget transparency, procurement, operations, personnel and public engagement as key corruption risk areas, and makes recommendations for reform.
