What is a critical factor when devising a rescue plan for a responsive casualty?

When devising a rescue plan for a responsive casualty, tactical feasibility is paramount. This factor encompasses the overall context of the mission, including the environment, available resources, and potential threats. A rescue plan must be realistic and executable given the tactical situation at hand, ensuring that the safety of both the casualty and the responding personnel is preserved.

A plan grounded in tactical feasibility allows for adaptability and real-time decision-making. It ensures that the rescue can be conducted without exposing personnel to unnecessary risks or complications that could arise from engaging in strategies that are not aligned with the mission's current realities. Therefore, focusing on what is tactically sound helps in mobilizing resources effectively and ensures a higher chance of a successful outcome in the rescue operation.
