Carries out orders (5)
I believe the answer is:
obeys
'carries out orders' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for obeys that I've seen before include "Does as one's told" , "Complies with orders" , "Listens to" , "Carries out (instruction)" , "Submits to authority" .)
