What should be the first priority for a combat lifesaver when approaching a casualty?

The first priority for a combat lifesaver when approaching a casualty is to assess the environment for safety. This is crucial because the safety of both the rescuer and the casualty takes precedence before any medical intervention can take place. If the environment is unsafe, such as in the presence of ongoing combat threats or other hazards, the lifesaver may become a casualty themselves, which would not only endanger their own life but also complicate the situation for the casualty.

Assessing the environment allows the lifesaver to identify any potential dangers such as enemy fire, explosives, or hazardous conditions that could hinder the rescue effort. Only after ensuring that the environment is secure can the lifesaver begin providing care effectively. This initial assessment lays the foundation for a successful rescue operation and facilitates optimal medical treatment while minimizing risk to personnel.
