This paper investigates public attitudes toward types of war casualties. Through a survey experiment, we examine Taiwanese responses to hypothetical scenarios involving casualties among Taiwan's own military, the US military as allies, the Chinese military as enemy combatants, and mainland Chinese civilians. Our paper reveals three findings: first, there is a stronger aversion among Taiwanese citizens to their own military casualties compared with those of their allies. Second, Taiwanese attitudes toward their own military casualties are more adverse than those incurred by enemy military. Lastly, Taiwanese support for military action diminishes more significantly with Chinese civilian casualties than with Taiwanese military losses.
