Rake with gunfire (6)
I believe the answer is:
strafe
'rake with gunfire' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for strafe that I've seen before include "Attack with machine-guns from the air" , "Attack with machine-gun fire" , "Set RAF to attack with gunfire" , "Attack with machine guns or cannon from a low-flying plane" , "Attack with machine-gun from the air" .)
