What term is used for the operational strategies to be turned to when an incident exceeds capabilities?

The term "Defensive" refers to operational strategies that are employed when an incident escalates beyond the capabilities available to manage it effectively. In such scenarios, defensive strategies prioritize the protection of life, property, and the environment, often by establishing barriers or strategies that limit the incident's impact rather than attempting to eliminate it immediately. This approach is essential when resources are overwhelmed, and the safety of personnel and the public becomes a primary concern.

For example, in firefighting, defensive tactics might involve creating firebreaks or protecting exposures rather than directly attacking a large, uncontrolled blaze. This strategic shift emphasizes safeguarding what can be protected instead of aggressively pursuing a solution that may not be feasible under the circumstances. Such defensive measures are crucial for managing emergencies safely while additional resources or support are mobilized.
