Army man runs country (7)
I believe the answer is:
myanmar
'country' is the definition.
(Myanmar is an example)
'army man runs' is the wordplay.
'runs' is an anagram indicator.
'army'+'man'='armyman'
'armyman' is an anagram of 'MYANMAR'.
(Other definitions for myanmar that I've seen before include "Country on the Bay of Bengal" , "Another name for Burma" , "Army man in new Burma" , "Modern name for Burma" , "Yangon is its capital" .)
