Non-military person (8)
I believe the answer is:
civilian
'non-military person' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for civilian that I've seen before include "Non-combatant" , "Nonmilitary person" , "Member of a country" , "He's not in the clergy or military" , "Citizen (non-military)" .)
