Units ordered to the capital (5)
I believe the answer is:
tunis
'the capital' is the definition.
(Tunis is an example)
'units ordered' is the wordplay.
'ordered' indicates anagramming the letters.
'units' anagrammed gives 'TUNIS'.
'to' acts as a link.
(Other definitions for tunis that I've seen before include "North African location" , "North African port and capital" , "Capital of a republic in north Africa" , "Carthage lies near this N. African city" , "Tom, Dick or Harry" .)
