During which phase should the evacuation of casualties ideally begin?

The correct phase for the evacuation of casualties to ideally begin is during Tactical Evacuation Care. This phase focuses on the transportation of casualties from the point of injury to higher levels of medical care. During Tactical Evacuation Care, successful evacuation strategies can be implemented, and casualties are stabilized for transport.

In this phase, it is crucial to ensure that the casualties have received initial care and are ready for evacuation. This includes monitoring their vital signs and any immediate protective medical interventions, allowing them to be moved safely to definitive care facilities.

The other phases have specific roles in the care of the casualty. For instance, Care Under Fire primarily involves life-saving interventions while under hostile conditions; it is not typically safe or practical to begin evacuations due to ongoing combat. Tactical Field Care focuses on providing care in a more stable environment but is still generally not centered around moving casualties to evacuation points. Post-evacuation Phase relates to care that happens after a casualty has been evacuated, where transport logistics and follow-up care come into play.

Thus, Tactical Evacuation Care is the appropriate phase for beginning the evacuation of casualties, as it ensures that the necessary preparatory care has been completed prior to transport.
