Shoot from cover (5)
I believe the answer is:
snipe
'shoot from cover' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for snipe that I've seen before include "The bird to shoot from cover" , "Wading bird; shoot from concealment" , "Curlew or sandpiper" , "Game bird" , "Shoot from place of concealment" .)
