Non-specific officer (7)
I believe the answer is:
general
This clue is a double definition.
'non-specific' is the first definition.
(I've seen this in another clue)
'officer' is the second definition.
(general officer is a kind of officer)
(Other definitions for general that I've seen before include "High ranking officer" , "Leader" , "Enlarge (anag.)" , "blanket" , "Usual; overall" .)
