Type of punishment for NCO (8)
I believe the answer is:
corporal
I believe this clue is a double definition.
'type of punishment' is the first definition.
(I've seen this in another clue)
'nco' is the second definition.
(I've seen this before)
'for' acts as a link.
(Other definitions for corporal that I've seen before include "material" , "Like old-fashioned punishment" , "Of the body, or army NCO" , "Bodily" , "Of the body, like NCO" .)
