NCO has gear sent out (8)
I believe the answer is:
sergeant
'nco' is the definition.
(I've seen this before)
'gear sent out' is the wordplay.
'out' indicates an anagram (out can mean wrong or inaccurate).
'gear'+'sent'='gearsent'
'gearsent' anagrammed gives 'SERGEANT'.
'has' acts as a link.
(Other definitions for sergeant that I've seen before include "Reagents (anag)" , "Military rank" , "Gets near (anag) -- NCO" , "officer of the law" , "Copper" .)
