Pilot bombing marina (6)
I believe the answer is:
airman
'pilot' is the definition.
(I've seen this before)
'bombing marina' is the wordplay.
'bombing' indicates anagramming the letters.
'marina' anagrammed gives 'AIRMAN'.
(Other definitions for airman that I've seen before include "crew member" , "Pilot" , "Male flyer" , "He flies" , "Flier" .)
