Army man reformed country (7)
I believe the answer is:
myanmar
'country' is the definition.
(Myanmar is an example)
'army man reformed' is the wordplay.
'reformed' is an anagram indicator.
'army'+'man'='armyman'
'armyman' is an anagram of 'MYANMAR'.
(Other definitions for myanmar that I've seen before include "Far East location" , "Another name for Burma" , "Country on the Bay of Bengal" , "Modern name for Burma" , "Country of SE Asia" .)
