Which phase of TCCC is primarily focused on managing life-threatening conditions?

The phase of TCCC primarily focused on managing life-threatening conditions is Care Under Fire. During this initial phase, the primary goal is to address immediate threats to life while still in a combat situation. Medical personnel are trained to assess and manage critical injuries quickly, often under fire or in a chaotic environment. This phase emphasizes controlling hemorrhage – the most common cause of preventable death on the battlefield – and delivering essential support even when conditions are not secure.

This approach is crucial because it allows for quick intervention that could save a life before the casualty is moved to a safer location for further treatment. Care Under Fire prioritizes the balance of providing medical care while ensuring the safety of both the medical providers and the casualty, making it distinct from later phases, which focus more on stabilization and evacuation.
