What should a medic assess before providing care to a casualty in a tactical situation?

In a tactical situation, assessing potential threats in the environment is paramount for a medic before providing care to a casualty. This evaluation helps ensure the safety of both the medic and the casualty, as threats like enemy activity, hazardous terrain, or explosive risks could compromise the medic's ability to render aid effectively. Being aware of these threats allows the medic to make informed decisions about the timing and method of care, and whether it is safe to proceed with immediate medical interventions or if the situation requires extraction to a safer location first.

While knowing a casualty's allergies and medical history are important for providing effective treatment, these factors can be gathered during the care process if conditions permit. The personal background of the casualty may be relevant but is secondary to ensuring an immediate safe environment to deliver care. Hence, assessing environmental threats takes precedence in a tactical scenario.
