Which of the following is NOT a phase of TCCC?

The correct response highlights that "Assess damage" is not a recognized phase in the Tactical Combat Casualty Care (TCCC) protocol. TCCC focuses on providing care in high-stress environments, primarily those seen in combat. The primary phases of TCCC are Care Under Fire, Tactical Field Care, and Tactical Evacuation Care.

In the context of TCCC, the initial phase, Care Under Fire, emphasizes personal and peer protection, which includes actions such as returning fire to ensure safety and moving casualties to cover, creating a safer environment for providing care. The aspect of "Self-aid, buddy aid" aligns with the imperative of providing immediate care while still under threat.

Thus, the phases of TCCC do not include "Assess damage," as the focus is on delivering aid as quickly and effectively as possible rather than evaluating damage before taking action. Therefore, this is why the answer "Assess damage" does not fit within established TCCC framework.
