Country units in country (9)
I believe the answer is:
indonesia
'country' is the definition.
(Indonesia is an example)
'country units in' is the wordplay.
'country' becomes 'india' (India is an example).
'units' becomes 'ones' ('one' can be a synonym of 'unit').
'in' is an insertion indicator.
'india' enclosing 'ones' is 'INDONESIA'.
(Other definitions for indonesia that I've seen before include "State" , "somewhere in Asia" , "Muslim republic" , "SE Asian country" , "An ionised country of South East Asia" .)
