Crossword Genius

Deviant sailor and soldier imprisoning Queen and King (8)

Ross

I believe the answer is:

aberrant

'deviant' is the definition.
('aberrant' can be a synonym of 'deviant')

I can't explain the remainder of the clue.

(Other definitions for aberrant that I've seen before include "Divergent from the normal" , "Irregular" , "Diverging from the norm" , "Deviating from what is accepted" , "departing from standards" .)

I've seen this clue in The Independent.
