Shoot the carrier! (3)
I believe the answer is:
bag
This clue is a double definition.
'shoot' is the first definition.
(I've seen this in other clues)
'carrier' is the second definition.
(I've seen this before)
'the' acts as a link.
(Other definitions for bag that I've seen before include "The amount of game shot by sportsman" , "Container for carrying thing" , "Piece of luggage" , "Pouch" , "Sack" .)
