Army medic's procedure (6)
I believe the answer is:
triage
'army medic's procedure' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for triage that I've seen before include "Assignment of urgency to illnesses" , "Determination of patient priority for treatment" , "Selection and allocation for medical aid" , "Hospital reception" , "Hospital procedure" .)
