I believe the answer is:

staff

I'm a little stuck... Click here to teach me more about this clue!

'kind of officer' is the definition.
(I've seen this in another clue)

I can't explain the remainder of the clue.

(Other definitions for staff that I've seen before include "Hands" , "Stick of authority" , "team?" , "Crew" , "Rod of authority" .)

I've seen this clue in the Evening Standard.
