A "casualty" refers to a person who is injured or killed in an accident, disaster, or military conflict. This term is often used in reports to describe the impact of events such as car accidents, natural disasters, or armed conflicts. Casualties can include both fatalities and those who sustain injuries requiring medical attention. In a broader context, the term can also apply to the loss of resources or equipment in various situations. For example, in a military operation, a casualty might refer to damaged vehicles or lost supplies, highlighting the overall cost of the event beyond just human loss.
