When does tactical field care typically commence?

Tactical field care typically commences during the assessment of the casualty. This stage occurs after the initial care under care under fire, when the provider has moved to a safer environment and can begin a thorough evaluation of the patient's injuries and condition. At this point, the medic can address both life-threatening conditions and any other injuries while considering the tactical environment.

The mention of the METC, which refers to the Medical Education and Training Campus, highlights that while there are established principles and guidelines, the context and specific training received can vary depending on the program and unique situations encountered in the field. Hence, tactical field care timing can sometimes be influenced by the training framework, but it predominantly starts with the casualty assessment phase.

The other options pertain to different aspects of emergency care and do not align with the specific timing of tactical field care in the context of combat scenarios.
