Officer with drunken count is fair target (7)
I believe the answer is:
coconut
'fair target' is the definition.
(I've seen this before)
'officer with drunken count' is the wordplay.
'officer' becomes 'co' (Commanding Officer abbreviation).
'with' says to put letters next to each other.
'drunken' indicates anagramming the letters.
'count' is an anagram of 'conut'.
'co'+'conut'='COCONUT'
'is' acts as a link.
(Other definitions for coconut that I've seen before include "one of a lovely bunch?" , "Large palm fruit" , "Shy occupier" , "Hard-shelled fruit of palm tree with white lining" , "Palm tree product" .)
