Strategic maneuver (6)
I believe the answer is:
tactic
'strategic maneuver' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for tactic that I've seen before include "Scheme or ploy used in battle, sport, etc, often within an overall strategy" , "Device" , "Action/strategy to achieve a specific end" , "Strategy carefully planned to achieve a specific end" , "Military means to an end" .)
