Shoots out from hiding (6)
I believe the answer is:
snipes
'shoots' is the definition.
(sniping is a kind of shooting)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for snipes that I've seen before include "Fires from place of concealment" , "Shoots from a concealed position - at birds of marshy areas?" , "Petty verbal attacks on the wading birds" , "Puts down" .)
