The key idea is using casualty precedence to guide evacuation priorities. Precedence assigns a urgency level to each patient, indicating how soon they must be moved and treated. By counting how many casualties fall into each precedence category, planners determine how many evacuation missions are needed and choose the most efficient routes and destinations for those patients. This ensures the most urgent cases get rapid transport and access to appropriate medical facilities, while less urgent cases are scheduled around available assets.

This concept isn’t about unit identifiers like squadron color, nor about a patient’s insurance status or when medical supplies are dropped. Those factors don’t drive evacuation sequencing or routing; patient movement decisions hinge on clinical urgency and the aim to maximize survivability with the available evacuation assets.
