What best defines 'risk' in a military context?

In a military context, 'risk' is best defined as the probability and severity of potential loss. This definition encompasses both the likelihood of an adverse event occurring and the potential consequences if that event does occur. Understanding risk in this way allows military planners and decision-makers to assess not only how frequently an enemy action or another threat might arise but also the degree of impact it could have on objectives, personnel, equipment, and mission effectiveness.

This comprehensive view of risk is essential in military operations, where both the chances of encountering threats and the possible outcomes must be evaluated to create effective strategies and contingency plans. It informs decision-making processes, resource allocation, and operational planning by considering both the uncertainty of threats and the implications of their realization.

Other definitions may focus on narrower aspects such as the presence of enemies or the existence of hazards, missing the broader perspective that includes both odds and consequences, which are crucial elements in effective military risk assessment and management.
