Crook or crew (5)
I believe the answer is:
staff
I believe this is a double definition.
'crook' is the first definition.
(I've seen this before)
'crew' is the second definition.
(I know that crew is a more specific form of the action man)
(Other definitions for staff that I've seen before include "Baton" , "Personnel or wooden pole" , "Post - office workers" , "Stick - office employees" , "Administrators etc - stick" .)
