Corruption in defense is much more than a moral issue. Cases of corruption impact negatively the efficiency of defense establishments, while defense budgets are under ever increasing pressures. Further, unchecked corruption reduces the level of defense capabilities, impacts the operational effectiveness of the armed forces and puts soldiers lives at increased risks. It lowers the military’s standing in society and the level of respect by international partners. In its extreme manifestation, corruption may threaten democratic governance mechanisms and even the foundations of a modern state. The increasing understanding of problems associated with defenserelated corruption led, inter alia, to the launch of the NATO Building Integrity Initiative in 2008. Its first phase focused on the development of a training course, a defense integrity self-assessment tool, and a compendium of good practices in building integrity and reducing corruption in defense, published jointly by NATO and the Geneva Center for the Democratic Control of Armed Forces (DCAF).
