American army officer, or a martial arts expert? (9)

I believe the answer is:

coloradan

'american' is the definition.
(I know that Coloradan is a type of american)

'army officer or a martial arts expert?' is the wordplay.
'army officer' becomes 'col' (short for colonel).
'martial arts expert?' becomes 'dan' (I've seen this in other clues).
'col'+'or'+'a'+'dan'='COLORADAN'

(Another definition for coloradan that I've seen is " from a particular American state".)

I've seen this clue in The Times.
