Some feared capricious military cop (6)

I believe the answer is:

redcap

'military cop' is the definition.
(term for a member of the Royal Military Police)

'some feared capricious' is the wordplay.
'some' says the answer is hidden in the clue (some of the parts of the word are used).
'REDCAP' is hidden within 'feared capricious'.

(Other definitions for redcap that I've seen before include "MP" , "Hole from explosion" , "Mil. policeman (colloq.)" , "Military policeman (slang)" , "bird!" .)

I've seen this clue in The Times.
